Int J pharm Sci Drug Res 2017, 9(3), 118-25.
The present study was aimed to formulate and evaluate chitosan nanoparticles containing acyclovir as potential ophthalmic drug delivery system. The topical application of acyclovir as eye ointment remains a concern for effective management of various ocular viral diseases owing to poor ocular drug bioavailability. The acyclovir loaded chitosan nanoparticles were prepared by ionic gelation of chitosan. Differential scanning calorimetry and fourier transform infra red spectroscopy measurements were carried out on the prepared nanoparticles, pure acyclovir and chitosan polymer. Fifteen different formulations were prepared and evaluated for particle size, Zeta potential, scanning electron microscopy, entrapment and loading capacity and in-vitro drug release profile. All the prepared formulations resulted in nano size in 377.9 to 720.6 nm and displayed spherical shape with zeta potential of +33.2 to +42.8 mV. The encapsulation efficiency and loading capacity were 70.7% - 90.9% and 25% - 50.8% respectively. The acyclovir loaded chitosan nanoparticles displayed crystallinity than acyclovir. The in-vitro release profile of acyclovir from the nanoparticles showed a sustained release of the drug over a prolonged period of 24 hours and fit best with Higuchi model with zero order and non- Fickian diffusion was superior phenomenon. The in vivo results reveal that ocular viral infections can be inhibited by the nanoparticles more significantly than the drug in conventional dosage forms. No appreciable difference was observed during 90 days in which nanoparticles were stored at various temperatures. Thus the results suggest that acyclovir loaded chitosan nanoparticle suspension appears promising for effective management of ocular viral infections.

Most low density bags are made from polythene, a chemically inert compound consisting of carbon and hydrogen. Burning of this plastic waste and burying of the plastics releases harmful toxic material which is a major pollutant in environment. Degradation of waste plastics through microorganism is the alternative method to deal with such problems. In this present study low density polythene bags degrading bacteria were isolated from greater Visakhapatnam dumping yard. Out of 20 isolates, one isolate was selected, due to its significant activity in biodegradation of polymer. After 30 days of incubation the isolate resulted 28% in weight loss of polythene bags. SEM images of the treated polythene bags confirmed that the isolate is having significant biodegradation ability by forming holes on the surface. Increased biomass of the bacteria on polymer and decreased biomass in spent medium indicates the significant utilization of polythene, as carbon source. The degraded material contains 5x102 CFU/mL of bacteria. Morphology and biochemical tests confirmed that isolate belongs to Pseudomonas sp. This work reveals that the atmospheric conditions of Visakhapatnam supports the biodegradation of plastic materials by microorganisms to control pollution of terrestrial and marine regions in some extent.

Antipsychotic prescription patterns are fundamentally different across countries due to variations in factors including health care polices, availability, cost of drugs, and preferred treatment modalities. The burden of illness is enormous although it remains grossly under represented. The objectives of this study were to assess the risk factors and co-morbidities in psychiatric disorders, evaluate the prescribing pattern of antipsychotic drugs and its conformance to treatment guidelines, and study drug related problems. Those patients above 18 years diagnosed with psychiatric disorders for at least 6 months were considered eligible. The adverse effects and prescribing pattern of antipsychotics were evaluated. International guidelines were used to create conformance indicators. 100 patients were enrolled for this study out of which 45% were male and 55% were female. The major population belonged to the age group of 31-40 years and majority of these patients were diagnosed with Bipolar Affective Disorder (BPAD). Diabetes and hypertension were the common co-morbidities. Most patients received a combination of mood stabilizers with antipsychotics. Also, most of the patients on lithium reported tremors and headaches. Among the four selected - 116 - drugs, order of appropriateness from high to low as per indication was lithium and resperidone followed by olanzapine and sodium valproate. Assessment of risk factors and comorbidities for psychiatric disorders plays a key role, as a considerable number of subjects posses one or more risk factors. This study emphasizes the need for therapeutic drug monitoring of narrow therapeutic index drugs due to high risk of adverse drug reactions.

Int J pharm Sci Res 2016, 7(10), 4064-73.
Asthma is obAdd Newstructive disease characterized by bronchoconstriction and inflammation for which beta 2 (β2) agonists that act through the β2 adrenoceptor are the first line agents of choice. Glycine16Arginine (Gly16Arg) is a common single nucleotide polymorphism (SNP) of β2 adrenoceptor whose effects on treatment response remain inconclusive. Hence the study aims to understand and determine the effect of the Gly16Arg SNP on β2-agonist binding and treatment responsiveness. Structure guided mutagenesis was performed with discovery studio tool, energy minimization was performed using Chemistry at Harvard Macromolecular Mechanics(CHARMM) force field, protein confirmation was studied using Ramachandran plot, Molecular docking analysis was performed using Autodock 4.2 and statistical analysis was performed using Graph pad prism 6.0. Statistically significant difference was observed between the binding energies of Glycine16 (Gly16) and Arginine16 (Arg16) groups. Further, the binding energies of β2 agonists were found to be comparatively less in Arg16 group than the Gly16 group suggesting - 115 - that the Arg16 variant carriers may be poor responders of β2 - sympathomimetic therapy. Presence of functional non synonymous single nucleotide polymorphisms in the β2 adrenoceptor significantly alters β2sympathomimetic binding. Patients with Arg16 variant may therefore be poor or non-responders of conventional bronchodilator therapy.

Formulation of poorly water-soluble drugs has always been a challenging problem for scientists and is expected to become a bigger challenge since approximately 40% or more of the new chemical entities being generated through drug discovery programs are poorly water-soluble. A poorly water-soluble drug indicates insufficient bioavailability following oral administration, resulting in fluctuating plasma levels and is largely dependent on meals. Simvastatin is one such agent. The purpose of this study was to formulate and optimize simvastatin nanosuspension. In the present work, simvastatin nanosuspension was prepared by nano milling technique using yttrium stabilized zirconium oxide beads as the milling media. A series of polymers and surfactants were screened, and HPMC E3 was selected for further studies. Central composite design (CCD) was adopted to optimize formulation parameters. The optimized nanosuspension was lyophilized and characterized by particle size distribution (PSD),polydispersity index (PDI), drug content, and x-ray diffraction (XRD). Its dissolution profile was compared with that of the micronized pure drug and marketed product. Optimized nanosuspension showed spherical shape with surface oriented stabilizer molecules and a mean particle diameter of 225 nm. There was no change in crystalline nature after formulation and it was found to be chemically stable with high drug content.

Int J pharm Sci Res 2016, 7(10), 4253-62.
The seeds of Vitis vinifera have been shown to have antioxidant, anticancer and antimicrobial properties due to the presence of rich bioactive phenolic components like resveratrol. The research deals with the synthesis of silver nanobioconjugates from the methanolic extract of grape seeds and the pure compound resveratrol. The presence of resveratrol was confirmed by HPLC analysis in methanolic extract of various parts of grape fruits such as skin, pulp and seeds of two varieties (pink and black). As higher amount of resveratrol was present in the seed extract of pink grapes, it was selected for the silver nanobioconjugate synthesis. Various conditions were applied to influence the rapid reduction of Ag+ to Ag°, such as microwave heating, water bath heating, sunlight exposure and incubation at 37°C for nanobioconjugate synthesis. The reduction of silver ions was confirmed by color changes, adsorption spectroscopy (280-800nm) and percentage yield. Among the four different methods, sunlight exposure proved to be rapid in the synthesis and the yield of nanobioconjugates was also high. Therefore, this method was chosen for the synthesis of silver nanobioconjugates using resveratrol. The bioactivity of the synthesized silver nanoconjugates were also evaluated through antimicrobial activity. The results showed that the resveratrol in grape seeds extract can act as good reductant and stabilizer for the silver nanobioconjugate synthesis, which also exhibits potent bioactivity.

A novel reverse phase liquid chromatographic method has been developed for the simultaneous estimation of Atorvastatin Calcium, Ezetimibe and Fenofibrate in bulk and Pharmaceutical formulations by using reverse phase Agilent 100-5 C18 column [250mm x 4.6mm]. The mobile phase (Methanol: water) in the ratio of 70:30% v/v was pumped at a flow rate of 1ml/min and the column effluents were monitored at 250nm using Variable Wavelength UV detector. Linearity was obtained in the concentration - 110 - range of 20-100 μg/ml for Atorvastatin and Ezetimibe and 50-250μg/ml for Fenofibrate. The established method was statistically validated according to the ICH Q2B guidelines and the percentage relative standard deviation for precision, robustness and ruggedness was found to be less than 2% indicating high degree of precision and robustness. The percentage recovery for the accuracy was found to be 100.52%, 100.45% and 101.31% for Atorvastatin, Ezetimibe and Fenofibrate respectively which were within the specified limits of recovery. Assay for the marketed formulation proved that 99.86% of Atorvastatin, 99.61% of Ezetimibe and 99.83% of Fenofibrate. Hence due to its simplicity, rapidity, precision and accuracy the developed HPLC method can be applied for the estimation of Atorvastatin, Ezetimibe and Fenofibrate in pure and marketed formulations by a modern analyst.

Curcuminoids are dietary phytochemicals obtained from dried rhizomes of turmeric plant (Curcuma longa). Curcuminoids are mixture of curcumin, demethoxy curcumin and bisdemethoxy curcumin in which curcumin is a major constituent. Several polymorphic forms of curcumin were reported. The present study relates to the preparation of different solid forms of curcuminoids and to study the influence of other constituents of curcuminoids on the polymorphic behaviour of curcumin. The developed solid forms were characterized by various spectral methods like Fourier Transform Infrared Spectroscopy (FTIR), Powder X- ray diffraction (PXRD), Differential Scanning Calorimetry (DSC) and Scanning Electron microscopy (SEM). On crystallization from ethanol and upon melt crystallization, curcuminoids underwent transformation into an amorphous form. Grinding did not affect the polymorphic nature of curcuminoids. These findings suggest that curcuminoids undergo polymorphic modifications very similar to curcumin.

Man has been dependent on plants for the treatment and cure of different diseases since time immemorial. Plants have served not only as a source of food and shelter but also as a very important source of different "portions" used for the treatment and cure of diseases. These portions are herbal or plant based mixtures made by traditional healers; who are individuals having a knowledge of medicinal plants of that particular area. In India, there are several thousands of medicinal plants, known to be used for specific diseases. Canavalia virosa is one such plant, known to be used for different curative purposes. However, it is more popular as a food plant as it is a tribal pulse. Canavalia virosa is a flowering plant belonging to the family Fabaceae. It is one of the lesser know vines from the genus Canavalia. It is not only important as an alternative protein source but also a promising medicinal plant as indicated by traditional medicine systems. This paper brings together some of the work carried out on this wonder plant by different researches.

Int J Sci Nat 2017, 8(1), 154-7.
Micropropagation is a widely implemented technique for production of a large number of plantlets in a very short period of time and in a trifling space of a culture room. Shoot tips and meristem culture techniques offer an opportunity for virus free plants production. In the present study, shoot tip culture technique was used for the production of plantlets of Saccharum officinarum (var. Co 92005). Shoot tips of size 0.5 cm dissected out from actively growing twigs of 6-8 month old plants, were cultured on MS basal medium supplemented with different concentrations of BAP and coconut milk. MS medium with 0.5 mg/l BAP and 20 per cent coconut milk was found to be best for culture initiation and establishment with 100 per cent response and maximum elongation of shoots. The same medium was found better for multiple shoot formation with 100 per cent response and maximum shoot multiplication. Maximum rooting response was observed on MS medium with 2.5 mg/l IBA with 100 per cent response with an average number of roots 2.93 roots/shoot and average root length 2.5 cm within two weeks. The rooted plantlets were transferred to pots filled with coco peat and were hardened under a polytunnel with 90 per cent survival after 15 days.

Gastroretentive drug delivery systems have shown to be of a better significance in controlling the release rate for drug having site specific absorption. The aim of the present investigation was to develop non effervescent floating matrix tablets of atenolol. Since atenolol is a BCS class III drug, aim was to get controlled release and also to increase permeability in vivo. So, non effervescent floating matrix tablet was prepared using lipophilic surfactant and hydrophilic polymers. The prepared hot melt granules (HMG) were characterized by Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC) and X-ray diffraction (XRD). There was no incompatibility observed in HMG. The HMG based floating matrix tablets were optimized by Box Behnken design to study the effect of independent variables, i.e. drug: lipophilic polymer ratio (X1), drug: total polymer ratio (X2) and hydrophilic polymer I: hydrophilic polymer II ratio (X3) on dependent variables like % drug released at 1, 6 and 10 h. All batches - 108 - showed good floating properties with total floating time more than 12 h. From the regression analysis, it was observed that all three independent variables show significant effect on the response variables. There was no significant change after 6 months of stability study of optimized batch.

The study was investigated to establish the diuretic and antiurolithiatic activities of chloroform and ethanolic leaf extract of Melochia corchorifolia. The chloroform and ethanolic leaf extract were administered to experimental rats orally at a dose of 200 mg/ kg and 400 mg/kg. Furosemide (5 mg/kg) was used as reference standard for diuretic activity. The parameters measured for diuretic activity was total urine volume; urine electrolyte concentrations such as sodium, potassium, chloride and bicarbonates. In in-vitro antiurolithiatic activity, Calcium oxalate crystallization was induced by the addition of 0.01M sodium oxalate solutions in synthetic urine. The effect of chloroform and ethanolic leaf extract of Melochia corchorifolia (100, 200 and 500 μg/ml) was studied by time course measurement of absorbance at 620 nm for ten minutes by means of a spectrophotometer. Both the extracts show good in-vitro antiurolithiatic activity. In in-vivo antiurolithiatic activity, urolithiasis was induced in male rats by administering ethylene glycol (0.75% v/v) in drinking water for 28 days and the parameters such as oxalate, calcium and phosphate were estimated in urine. Serum creatinine, calcium and uric acid were also estimated. Treatment with the leaf extract of Melochia corchorifolia restored all biochemical, urinary parameters.

Ulcerative colitis comes under inflammatory bowel disease (IBD), a disease of colon, with inflammation confined mostly to mucosa characteristically affecting the rectum. Mesalamine has been used in the maintenance of remission in ulcerative colitis and management of mild to moderate active disease. Thus, it is used as the model drug in the present study and to formulate mesalamine retention enema and its comparative evaluation with the marketed product - MESACOL (Mesalamine Rectal Suspension USP). The suspensions were formulated by controlled flocculation method to maintain the sedimentation volume as that of marketed product. Xanthan gum and guar gum were used as suspending agents and Carbopol 934 as flocculation retardant. The formulations were characterized for their appearance, redispersibility, pourability, assay, pH, rheological properties, sedimentation volume, particle size determination, in vitro drug release and short-term stability of the selected formulations. We observe that appearance, redispersibility, pourability and pH were within the acceptable limits. Particle size of the suspensions of almost all the formulations were lying in the range of 60-65μm as that of marketed product. Sedimentation volume and thixotropic behaviour of the suspensions with xanthan gum was good when compared to guar gum. The percentage of drug content was found to be between 94-100% which was within acceptable limits. In vitro drug release at the end of 30 min of F2 (100.04%) and F5 (101.91%) were better than marketed product (87.96%). At the end of short-term stability studies (2 months), Formulation F2 indicated no significant change in sedimentation volume, assay, pH, average particle size and redispersibility and hence it is the optimized formulation.

J pharma Sci Tech 2016, 5(2), 109-12.
Substitution of a pharmaceutical product with another depends among others on the extent of similarity and comparability of pharmaceutical quality parameters of such products. This research work was conceived to evaluate and compare properties of optimized formulations F-4 and F-6 with Artelum® (REF-P), a standard, registered and commercially manufactured Artemether - Lumefantrine (AL) fixed dose combination tablets. Pharmaceutical properties such as weight uniformity, hardness, disintegration (DT), friability and dissolution of F-4, F-6 and REF-P were evaluated and compared. Results of achieved properties were alluded to by process capability index (CpK). Indeed, with weight variation of less than 2% relative standard deviation (RSD), DT of less than 104 s, friability of less than 0.64%, hardness of greater than 4.5 Kp, hardness / friability ratio of greater than 7.7, artemether dissolution in 60 min of greater than 54.5% and lumefantrine dissolution in 45 min of greater than 80%, the pharmaceutical properties of F-4, F-6 and REF-P complied with quality standards that enabled them to deliver good performance as shown by CpK. With DT of less than 2 min and RSD of 0.93% - 1.11%, achieved qualities were better than predefined. It is opined that quality and risk management benefits inherent in quality by design (QbD) model has been brought to bear on F-4 and F-6 as alluded to by the achieved qualities which were in most cases better than predefined and comparable to REF-P.

J pharma Sci Tech 2016, 5(2), 105-8.
Arising from challenges of physicochemical properties of Artemether and Lumefantrine especially their low solubility and permeability, this research was put together to assess the implications on the physicotechnical characteristics of the resultant Artemether-Lumefantrine (AL) fixed dose combination tablets. Granules were prepared by wet granulation technique and compressed into tablets using manually operated tablet press with 12.5 mm; round and flat face punches and die. Compaction behaviours at different compression pressures of between 30 and 42 MNm-2, kinetics as well as mechanisms of dissolution of AL in the tablets were evaluated and compared. Results of compaction characteristics showed that formulation 6 (F-6) was easy to compress into tablets compared with formulation 4 (F-4) with mean yield pressure (Py, MNm-2) of 163.93 and 336.7 respectively. Kinetics of dissolution of artemether in F-4, F-6 and reference product (REF-P) followed Korsmeyer-Peppas modelwith erosion as mechanism of dissolution in F-4 and REF-P, and Fickian diffusion in F-6. On the other hand, kinetics of dissolution of lumefantrine in F-4 was shown to follow Hixson-Crowell, Korsmeyer-Peppas for F-6 and Zero model for REF-P with all the formulations following Fickian diffusion as mechanism of dissolution. In conclusion, despite its multi-component nature and strict adherence to design space (DS) component of quality by design (QbD), the physicotechnical properties of the formulations alluded to good performance which will facilitate building of better pharmaceutical quality parameters into final products. This will however be elucidated in subsequent research work.

Traditional uses for these plants treat specific conditions or diseases. The present study examined the antibacterial activity using the disk diffusion method using Ethanolic & Methanolic extract as part of the process of understanding the chemistry, toxicity and efficacy of these plant extracts. Methanolic and Ethanolic extracts of this plant was examined using a standard antimicrobial disk diffusion method. - 102 - Extracts were tested against both Gram negative (Escherichia coli, Vibrio cholerae, Salmonella typhi and Pseudomonas aeruginosa) & Gram positive (Bacillus cereus & Staphylococcus aureus) bacteria. Methanolic in vitro regenerated roots showed higher inhibition zone against all bacterial species while natural growing plant root extract showed minimum inhibition. In vitro regenerated root extract showed moderate inhibition zone against all bacterial species. S. aureus showed maximum (25.2 mm) inhibition zone in in vitro root methanolic extract while V. cholerae showed minimum (14 mm) in natural growing root extract. In ethanolic extract maximum inhibition zone (22.1 mm) was observed against S. aureus and another maximum inhibition zone (21.3mm and 21mm) was reported against B. cereus and P. aeruginosa respectively. These results served to validate our procedures and indicate the need for the present study. Implications of these results for bioactivity and drug discovery potential of plant extracts can be further explored. This study serves as basis for further research on these weed plants.

Pharmacog Mag 2017, 13(51), 385-92.
The prevalence of overweight-obesity and associated comorbidities have reached alarming levels necessitating the need to explore effective therapeutics. In the present work, we demonstrated the promising antiobesity activity of ethanolic fraction of Terminalia tomentosa bark (EFTT) in diet induced obese rat model. High Fat Diet (HFD)-fed obese rats were orally administered with EFTT (50, 100 and 200 mg/kg body weight). Changes in body weight, body - 101 - composition, bone mineral concentration, bone mineral density, plasma glucose, insulin, leptin, adiponectin, circulatory and tissue lipid profiles, and the activities of liver antioxidant enzymes, key lipid metabolic enzymes and mRNA expressions of fatty acid synthase (FAS), peroxisome proliferator-activated receptor gamma (PPAR-γ), leptin and tumor necrosis factor alpha (TNF-α) were assessed in experimental rats in the presence and absence of EFTT. At a dose of 200 mg/kg b.wt, EFTT has substantially attenuated body weight and related patho-physiological alterations in HFD-induced obese rats. These findings were correlated with histological observations of adipose tissue. The therapeutic activity of EFTT could be possibly through restoration of antioxidants status, regulation of key lipid metabolizing enzymes, expression of FAS, leptin, PPAR-γ and by synchronized control of energy metabolism in liver and adipose tissue.

The leaves of N. arbor-tristis are used in the Traditional Systems of Medicine like Unani, Ayurveda and Sidhha against different diseases such as obstinate sciatica, fever, diabetes and act as cholagogue, diaphoretic and anthelminitic. The major phytochemicals reported in leaves are triterpines and its glycosides, which may be responsible for various pharmacological - 100 - actions like anti-inflammatory, anti-spasmodic, antibilious, expectorant, laxative, diaphoretic, diuretic and anti-helmintic. Due to various pharmacological actions, commercialization of this drug to meet its increasing demand has resulted in a decline in its quality, because of lack of adequate regulations and scientific protocols. There is, therefore, a need to develop a systematic approach for authentication and develop well-designed methodologies for standardization of this important drug. In the present study, the reported pharmacopoeial parameters to evaluate the raw material and can be used as reference standards for the purpose of quality control/quality assurance of this drug are presented.

Int J Sci Nat 2017, 8(1), 132-7.
India is the second largest producer of silk after China. Hence the scope for increasing the silk production in our country is immense. A large number of varieties of silk worm are used for the silk production. Mulberry belongs to the family Moraceae which has more than 20 species and the common species found in India are, being Morus alba, M. indica, M. atropurpurea roxb, M. nigra, M. serrata and M laevigata. The composition of the leaves varies with variety, degree of maturity and the type of soil in which the plants are grown. Mulberry silkworm is a monophogus insect which feeds only on the mulberry leaves. Growth and development of silkworm and cocoon crop are mainly influenced by yield and nutritional quality of mulberry leaf used as feed. In the present study, the effect of yellow leaves of the mulberry variety V1 on the growth and biochemistry of haemolymph of the silk worm variety PMxCSR2 in three groups viz., 3rd to 5th instar, 4th to 5th instar and 5th instar was studied. In the first group, on the 16th day a significant increase in weight of 3.30 ±0.056 g was observed in the control when compared to the treatment which recorded a growth of only 0.27 ±0.016 g. In the second group, growth of only 0.25 ±0.006 g for the treatment and a significantly higher 2.29 ±0.030 g for the control were observed on the 12th day of rearing. In the third group, a significantly higher growth of 2.325 ±0.061 g in the control and only 0.74 ±0.094g in the treatment were recorded on the 9th day. The concentration of proteins and carbohydrates were significantly higher in the control in all the three groups when compared to the treatment while, the concentration of the lipids was significantly higher in the treatment in all the three groups when compared to the control. The concentration of the total proteins and carbohydrates in the yellow mulberry leaves were significantly lower when compared to those of green mulberry leaves confirming the fact that the nutritional value of the mulberry leaves significantly influence the growth and protein, carbohydrate and lipid content of the haemolymph of the silk worm in turn influencing the silk quality and quantity.

Int J pharm Sci Res 2016, 7(10), 4074-84.
The aim of the present study is to carry out fluorescence analysis, phytochemical extraction, preliminary phytochemical screening, estimation of total flavonoids, tannins, alkaloids, steroids saponins and in vitro antiurolithiatic studies on the leaf aqueous and ethanolic extracts of Bauhinia variegata. The results of fluorescence analysis indicate that the powder on treatment with 50% H2SO4 shows dark brown colour under UV. The results of preliminary phytochemical screening indicated the presence of saponin glycosides, tropane alkaloids and acidic compounds. The results of quantitative determination indicated that the aqueous extract contains highest amount of flavonoids expressed as 54.6 mg/gm equivalents of quercetin, maximum amount of tannins in ethanolic exract as 56.30 mg/gm equivalents of quercetin, equal amounts of alkaloids are present in both extracts as 25mg/gm equivalents of atropine sulphate, steroids and saponins in lowest amount. The in vitro antiurolithiatic activity was studied as percentage inhibition of stones by nucleation, growth and aggregation assays for aqueous and ethanolic extracts at 200-1000 μg/ml taking cystone tablets as standard. The results indicated that the inhibition of growth of crystals increased with increase in concentration of the extract. Therefore, the plant claimed to possess antiurolithiatic activity and further in vivo studies as well as isolation of individual compounds responsible for - 99 - the activity are necessary.

Hippocratic J Unani med 2016, 11(2), 79-94.
Due to unsystematic use of many antibiotics and antifungal drugs at higher doses at medical centers to get early medical and commercial benefits causes many problems to human health. Microorganisms developed resistance against many antimicrobial drugs and uses of these synthetic medicines are also associated with severe - 98 - adverse effects. Therefore, there is an urgent and constant need to develop new, safe and effective therapeutic agents for the treatment of infections. Dar-e-Hald (Berberis aristata) is a medicinal plant used in Unani System of Medicine since long time either as single drug or in compound formulations to treat infectious diseases. In this study Dar-e-Hald was screened for its antibacterial and antifungal activity against different gram positive and gram negative bacterial strains such as Bacillus sp, Staphylococcus aureus, Streptococcus pyogenes, Vibrio cholera, E. coli and Proteus sp.etc. and different fungal strains like Aspergillus flavus, Aspergillus fumigates, Aspergillus nigur, Candida albicans, Candida keyfr, Candida parapsilosis. The Aqueous and alcoholic extract and powder of the test drug was used to determine antibacterial and antifungal activity by disc-agar diffusion technique at three concentration levels (50, 25 and 12.5μg/disc) and compared with standard drugs. Ciprofloxacin (5 μg/ disc) taken as standard for antibacterial potential and for antifungal activity Fluconazole (10 μg/disc), Nystatin (100 μg/disc) and Amphotericin (100 μg/disc) were used. Zone of Inhibition was taken as the parameter for the assessment of antimicrobial activity. Minimum inhibitory concentration for alcoholic extract of Berberis aristata against bacterial and fungal strains was also determined. Dar-e-Hald shows significant activity against most of the bacterial and fungal strains used for the study. Furthermore, before testing these drugs for antimicrobial activity, the samples of the drugs were also checked for authenticity based on certain Physico-chemical parameters.

Pharmacog Mag 2017, 13(51), 358-62.
The objective of this study is to recognize the mechanism of anticancer, antidepression, and immunoregulation of D. sinensis Hemsl. Seventy-two steroidal glycosides of D. sinensis Hemsl. were evaluated on the docking behavior of tumor-associated proteins (PI3K, Akt, mTOR), depression-related proteins (MAO-A, MAO-B) and immune-related proteins (tumor necrosis factor-α [TNF-α], tumor necrosis factor receptor 2 [TNFR2], interleukin-2Rα [IL-2Rα]) using Discovery Studio version 3.1 (Accelrys, San Diego, USA). The molecular docking analysis revealed that mostly steroidal glycosides of D. sinensis Hemsl. exhibited powerful interaction with the depression-related protein (MAO-A) and the immune-related proteins (TNFR2, IL-2Rα). Some ligands exhibited high binding energy for the tumor-associated proteins (PI3K, Akt, mTOR) and the immune-related protein (TNF-α), but MAO-B showed none interaction with the ligands. This study has paved better understanding of steroidal glycosides from D. sinensis Hemsl. as potential constituents to the prevention of associated cancer, depression and disorders of immunoregulation.

The use of medicinal plants in the form of extracts and oils dates back to pre-historic times. The aim of the study was to determine the effect of Essential oil (EO) extracted from leaves of Plectranthus amboinicus on lung cancer cell line, A549. MTT assay was performed to check the efficacy of Essential oil to induce death in cancerous A549 cells and normal HEK293 cells. Acridine Orange/Ethidium Bromide staining, Hoechst staining and DNA fragmentation assays were used to confirm the apoptosis inducing ability of EO on A549 cells. RT-PCR and western blotting was performed to check the expression of pro- and anti-apoptotic factors. Calorimetric assay was done to check caspase-3 and caspase-9 activities. Essential oil at lower concentrations was found to induce cell death selectively in the lung cancer cells (IC50 = 10.74 μg/mL). The transcriptional expression studies of the pro-apoptotic Bax and anti-apoptotic Bcl-2; and the western blot analysis of pro-apoptotic BAK and BAD showed that EO upregulated the expression of pro-apoptotic factors and down regulated the expression of anti-apoptotic factors in A549 cells. Caspase-9 and 3 activities were found to be upregulated in the calorimetric studies. The down regulation of anti-apoptotic factors and upregulation of pro-apoptotic factors show that the Essential oil induced apoptosis in the lung cancer cells via the intrinsic or the mitochondrial pathway.

The seed oil of Zanthoxylum bungeanum Maxim (ZBSO) is considered to be rich source of fatty acids, mainly oleic and linoleic acids, and has been used for the treatment of burns in Chinese medicine. Objective: We evaluated the healing efficacy of ZBSO and explored its possible mechanism on scalded rats. Materials - 96 - and Methods: Sprague-Dawley rat models with deep second-degree burns were set up, and ZBSO (500 and 1000 μl/wound) was topically applied twice daily for 7 days and then once daily until wound healing. The therapeutic effects of ZBSO were evaluated by observing wound closure time, decrustation time, wound-healing ratio, and pathological changes. Collagen type-III, matrix metalloproteinase-2 (MMP-2), MMP-9, phospho-nuclear factor-kB (p-NF-kB) p65, inhibitor of NF-kB subunit α p-IkBα, and inhibitor of NF-kB subunit α (IkBα) expression were determined using Western blotting. Results: The ZBSO-treated group showed a higher wound-healing ratio and shorter decrustation and wound closure times than the untreated group. The topical application of ZBSO increased collagen synthesis as evidenced by an increase in hydroxyproline level and upregulated expression of collagen type-III on days 7, 14, and 21 posttreatment. A reduction in MMP-2 and MMP-9 expressions also confirmed the collagen formation efficacy of ZBSO. Furthermore, there was a significant increase in superoxide dismutase levels and a decrease in malondialdehyde levels in ZBSO-treated wounds. ZBSO also decreased tumor necrosis factor alpha, interleukin-1 (IL-1) β, and IL-6 levels in serum, upregulated IkBa, and downregulated p-NF-kB p65 and p-IkBα expression in vivo, indicating the anti-inflammatory action of ZBSO. Conclusion: ZBSO has significant potential to treat burn wounds by accelerating collagen synthesis and the anti-inflammatory cascade of the healing process.

China) : Optimization of surfactant-mediated, ultrasonic-assisted extraction of antioxidant polyphenols from rattan tea (Ampelopsis grossedentata) using response surface methodology. Pharmacog Mag 2017, 13(51), 446-53.
Rattan tea is a medicinal plant that has been used for many years for the treatment of inflammation, fatty liver, tumor, diabetes, and hyperlipidemia. A green and novel approach based on surfactant-mediated, ultrasonic-assisted extraction (SM-UAE) was developed for the extraction of antioxidant polyphenols from Rattan tea. A nonionic surfactant Tween-80 was selected as extraction solvent. The antioxidant activity was measured by total phenolic content (TPC) and ferric-reducing/antioxidant capacity (FRAC) assay. Optimization of extraction parameters including concentration of solvent, ultrasonic time, and temperature were investigated by response surface methodology. The antioxidant activity was measured by TPC and FRAC assay. The optimal extraction conditions were determined as 6.8% (v/v) of aqueous Tween-80, ultrasonic temperature of 54°, and ultrasonic time of 28.8 min. Under these conditions, the highest TPC value of 360.4 mg gallic acid equivalent per gram of dry weight material (GAE/g DW) was recorded. Moreover, 6.8% (v/v) of aqueous Tween-80, ultrasonic temperature of 54.5°, and ultrasonic time of 28.4 min were determined for the highest FRAC value of 478.2 μmol of Fe2+/g of weight material (μmol Fe2+/g DW). Compared with other methods, the TPC and FRAC values of 313.5 mg GAE/g DW and 389.6 μmol Fe2+/g DW were obtained by heat reflux extraction using ethanol as solvent, respectively, and 343.2 mg GAE/g DW and 450.1 μmol Fe2+/g DW were obtained by UAE using ethanol as solvent, respectively. The application of SM-UAE markedly decreased extraction time or extraction cost and improved the extraction efficiency, compared with the other methods.

The genus Wikstroemia has about 70 species, but only a limited number of species have been studied chemically. Wikstroemia indica has long been used as a traditional crude drug in China. However, there is no report about the bioactivity of Wikstroemia scytophylla. This paper reports the chemical investigation and biological evaluation of the W. scytophylla. The EtOAc extraction of W. scytophylla was isolated using chromatographic methods, and the compounds were analyzed by spectroscopic methods. The in vitro antitumor activities against five human cancer cell lines were performed according to the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method. The chemical investigation of the stems of W. scytophylla resulted in the isolation of 12 compounds mainly including one biflavone (1), - 95 - five flavones (2-6) compounds, and six lignans (7-12), in which compound 8 was a new natural product. Compounds 1 and 7-12 were evaluated for their antitumor activities while these compounds showed weak cytotoxicity with the half maximal inhibitory (IC50) values more than 40 μM. All of these compounds were isolated from this plant for the first time, and compounds 2-12 were first reported from genus Wikstroemia, in which compound 8 was a new natural product. Compounds 1 and 7-12 exhibited weak antitumor activities (IC50

Pharmacog Mag 2017, 13(51), 418-24.
GCSB-5, an herbal drug composition with an anti-inflammatory effect, is prepared by boiling, which is the most common herbal extraction method in traditional Korean medicine. Several parameters are involved in the process, i.e., extractant type, herb-to-extractant ratio, extraction temperature and pressure, and total boiling time. The aim of this study was to examine the influence of boiling time on index compound amount and the antioxidative and anti-inflammatory activities of GCSB-5. Different samples of GCSB-5 were obtained by decocting for 30, 60, 90, 120, 150, and 240 min. Each sample was tested for hydrogen ion concentration (pH), total soluble solid content (TSSC), marker compound profiles, and antioxidative and anti-inflammatory activity. pH was found to decrease while TSSC increased with extended decoction. Marker compound contents for GCSB-5 (acanthoside D for Acanthopanax sessiliflorus Seem, 20-hydroxyecdysone for Achyranthes japonica Nakai, and pinoresinol diglucoside for Eucommia ulmoides Oliver) remained relatively constant regardless of the length of boiling. Total D-glucose amount increased with longer boiling. The antioxidative and anti-inflammatory potentials of GCSB-5 were not substantially affected by decoction duration. Biological characteristics and marker compound content of GCSB-5 were not altered significantly in prolonged boiling.
