Six new Phthalic acid amides of the general formula C8H5O3-NH-R were prepared by the reaction of Phthalic anhydride with various amines namely Glycine, N, N-diphenyl amine, 1-naphthyl amine, 4-amino toluene-3-sulphonic acid, Toluene-p-sulphonamide, m-nitro aniline. The synthesized compounds were characterized by using IR, 1HNMR & 13CNMR spectroscopy. Petra Osiris Molinspiration (POM) analyses revealed the significant bioactivity by elucidating the structural parameters in drug design of the synthesized compounds. In this work we have performed POM of our synthesized compounds to predict their drug like behaviour. Petra program package was used for the calculation of physiochemical properties of the organic compounds. On the basis of findings of Petra analyses reveals that our synthesized compounds have potential pharmacophores for antiviral and anti bacterial activities. Prediction of bioactivity by Molinspiration software calculates druglikeness score against GPCR ligands, ion channel modulators (ICM), kinase inhibitors (KI), nuclear receptor ligands (NRL), protease inhibitors (PI) and other enzyme inhibitors (EI). All synthesized compounds showed better activity against ICM, KI, PI and NRL as compared to the reference...

Ascorbic acid is one of the essential and most vital medicines needed to maintain healthy living. Due to its non-availability through endogenous biosynthesis in humans, it is arguably one of the most consumed Over-The-Counter drugs. Thus, a simple, precise, low-cost and accurate reversed-phase liquid chromatographic (RP-LC) method was developed and optimized to analyse for the percentage content of ascorbic acid in different brands of Vitamin C syrups. The chromatographic separation carried out on an ODS (C18) Ultra sphere column, 5µm (25cm x 2mm), was achieved with HPLC water and methanol as the mobile phase, pumped at a flow rate of 1ml/min and using an ultraviolet detector for detection. The calibration curve was linear over the range of 10-100µg/ml and the method was found to be specific as no interference peaks of impurities and excipients were observed. The method developed was used to assess the quality of fifty-five samples of different types of Vitamin C syrup. Among the samples assessed for their percentage content of ascorbic acid, 18.2% fell below...

Objective: The present investigation is focused on detecting anti-carcinogenic potential of virgin coconut oil. Methods: The virgin coconut oil (VCO) from coconut endosperm was prepared by cold compression method. It was examined then for cytotoxicity by cell exclusion studies using trypan blue dye. Chemical carcinogenesis method using benzopyrene was used to study the anticarcinogenecity of VCO. Curcumin was taken as standard. The low dose and high dose VCO was compared with normal, vehicle and standard treatments. Biomarker studies and histopathological evaluation was also performed. Result: The VCO upto 9μl showed no significant cytotoxicity. The low dose (4ml/kg body wt) and high dose (8ml/kg body wt) of VCO had significant reduction in gastric Lactate Dehydrogenase (LDH) activity, which is a biomarker for gastric cancer. Histopathological reports also showed very less infiltrations and absence of hyperplasia compared to control. Conclusion: The present study showed that, the virgin coconut oil have anti-carcinogenicity property, thus it prevent hyperplasia in the stomach of mice, induced by...

Background: The plant Hamelia patens belong to a family Rubiaceae, which is rich in active phytochemicals like flavonoids and alkaloids. Although Plant has been traditionally used for the treatment of various ailments still no systematic pharmacognostical, phytochemical and pharmacological work has ever been carried out on this potential plant. Aim: The present study was carried out for the standardization and determination of in vitro antioxidant activity of the aqueous and methanolic extracts of aerial parts of plant Hamelia patens. Method: After the determination of all the standardization parameter, preliminary phytochemical analysis was done following various qualitative procedures for the determination of alkaloids, flavonoids, etc. Quantitative phytochemical analysis was performed for the determination of total phenolics by Folin-Ciocalteu method, total flavonoid by Aluminium chloride colorimetric assay and in-vitro antioxidant properties were evaluated by DPPH, ABTS and FRAP method. Result: Phytochemical analysis revealed the presence of various phytoconstituents like alkaloids, flavonoids etc. The highest amount of phenolic was found in the methanolic stem extract i.e. 236.22 mg of GA/g of extract...

Objectives: To obtain the data regarding the effects of sodium valproate on enhancement of monoamines mediated behavioural responses following administration of ECS for ten days to rats. Methods: Forty rats were selected for the study in which tonic-clonic seizures were developed fully after giving single maximal electroconvulsive shock (150V, 210mA). Four groups (n= ten in each) were received different treatment(duration= Ten days) 1) Control group- distilled water (2ml daily) 2) ECS pretreated group- single ECS daily 3) Valproate group- valproate suspension(5.4 mg/kg/day, p.o.) 4) Test group- Single ECS daily + valproate suspension one hour after ECS((5.4mg/kg/day, p.o.). Following behavioural studies were done on Day eleven – apomorphine induced stereotypy, lithium induced head twitches and clonidine induced sedation to study dopaminergic, serotonergic and noradrenergic functions respectively. Results: All Three scores i.e. apomorphine induced stereotypy; lithium induced head twitches and clonidine induced sedation were statistically significantly increased in ECS pretreated group as compared to control group. Apomorphine induced stereotypy score & lithium induced head twitches were statistically significantly decreased in test...
