SYNTHESIS, CHARACTERIZATION AND IN-VITRO ANTICANCER SCREENING OF VITIS VINIFERA SEED ETHANOLIC EXTRACT LOADED CHITOSAN NANOPARTICLES IN H-29 COLON CANCER CELL LINE
Nanotechnology can be applied to deliver and protect antioxidants in order to control the oxidative stress phenomena in several chronic pathologies. Chitosan (CS) and its carboxymethyl derivatives are smart biopolymers that are non-toxic, biocompatible, and biodegradable, and, hence, suitable for various biomedical applications, such as drug delivery gene therapy and tissue engineering. Vitis vini...

PREPARATION AND IN-VITRO EVALUATION OF APREMILAST EFFERVESCENT FLOATING TABLETS
Apremilast, the new PDE4 inhibitor drug, exhibits low solubility and low permeability; therefore, shows variable bioavailability. Effervescent floating tablets of apremilast were developed to sustain the drug release rate by increasing gastric retention time. These tablets were prepared by wet granulation technique, using different polymers like carbopol 934P, hydroxypropyl methylcellulose K4M, tr...

DEVELOPMENT AND VALIDATION OF BIOANALYTICAL METHOD FOR THE PHARMACOKINETIC STUDY OF FAMOTIDINE SNEDDS IN RATS USING RP-HPLC
A selective and high throughput RP-HPLC method was developed to detect and quantify Famotidine in rat plasma using Ranitidine hydrochloride as an internal standard (IS). After liquid-liquid extraction, the analyte and the internal standard were chromatographed on Enable 18H (5µ, 250×4.6mm) C18 column using 20 µL injection volume with a run time of 15 minutes. An isocratic mobile phase consistin...

NOVEL, RAPID, ISOCRATIC RP-HPLC METHOD DEVELOPMENT AND VALIDATION FOR SIMULTANEOUS ESTIMATION OF BETAMETHASONE DIPROPIONATE, MICONAZOLE NITRATE AND CHLOROCRESOL IN PHARMACEUTICAL DOSAGE FORM
A novel, rapid, isocratic, reversed-phase HPLC method was developed to simultaneously determine betamethasone dipropionate, miconazole nitrate and chlorocresol in a topical dosage form. The separation was performed on the C18 prontosil (250 x 4.6mm x 5µ) column. The mobile phase used for this study consists of acetonitrile and phosphate buffer of pH 2 in the ratio of 70:30 v/v, respectively. The ...

ANTIBACTERIAL ACTIVITY FROM BARK EXTRACTS OF PTEROSPERMUM ACERIFOLIUM (L.) WILLD.
Although there are many studies on antimicrobial activities of different plants, there is no report on antibacterial activity of Pterospermum acerifolium (Sterculiaceae). Therefore, a microbiological study was conducted to detect antibacterial activity of P. acerifolium. Successive ethanolic extract of bark of P. acerifolium were fractionated with hexane, butanol, methanol and water. In vitro anti...

ENHANCEMENT OF SOLUBILITY OF AN ORAL HYPOGLYCAEMIC DRUG, GLIMEPERIDE BY THE TECHNIQUE COCRYSTALLISATION
Co-crystallization is one of the most reliable alternative approaches to increase the solubility of poorly water-soluble drugs without affecting their physicochemical properties. Pharmaceutical cocrystals are neutral organic compounds connected to the API preferentially by loosely formed bonds as dipole-dipole interaction. Our present study aims at improving the solubility of an effective oral hyp...

DNA INTERACTION STUDIES BY UV OF COPPER COMPLEX BASED ON HETEROCYCLIC CHALCONES
Privileged structures have been widely used as an effective template in medicinal chemistry for drug discovery. Chalcone is a common simple scaffold found in many naturally occurring compounds. Chalcones, considered as the precursors of flavonoids and isoflavonoids, are abundant in edible plants. Chalcone metal complexes and their derivatives have been known over the past fifty years. Copper is an...
