The chemistry of pyrimidine is a blossoming field. Numerous method for the synthesis of pyrimidine and also their diverse reactions offer enormous scope in the filed of medicinal chemistry. The utility of pyrimidines as synthon for various biologically active compounds has given impetus to these studies. The review article aims to review the work reported and the chemistry and biological activitie...
PROLONG RELEASE BIOADHESIVE VAGINAL FILM OF ANTI-HIV DRUG (ZIDOVUDINE): FORMULATION AND IN- VITRO EVALUATION
The present study concerned with the development and characterization of bioadhesive vaginal film (VF). Zidovudine containing VF were prepared by solvent casting method using different ratios of Acrycoat S 100 (AC) or Ethyl cellulose (EC) to Hydroxy propyl methyl cellulose (HPMC) and di butyl phthalate(DBP) as a plasticizer. The optimized films were found to be transparent, flexible and soft and e...
The phytochemical analysis of the medicinal plant Kalonchoe pinnata was carried out to evaluate the antioxidant potential. Alcoholic extracts of the leaves was subjected to in vitro antioxidant activity screening models such as inhibition of lipid peroxidation, nitric oxide ,superoxide radical and hydroxyl radical scavenging activity. Ascorbic acid was used as the standard for superoxide anion rad...
The aim of the study was to evaluate the circulating antioxidant such as vitamin C, vitamin E and GSH in nickel (Ni) induced toxicity in rats and in vitro free radical scavenging assay. In this investigation nickel sulfate (20 mg/kg body weight (b.w.) was administered intraperitoneally (i.p.) for 20 days to induce toxicity. Naringin was administered orally (80 mg/kg body weight) for 20 days with i...

(Guava) family Myrtaceae is an important dietary plant used traditionally for medicinal purpose around the world. The fruit part of the guava is used because of its food and nutritional value but other part of the guava plant are used in the traditional system due to their medicinal p...
DEVELOPMENT AND VALIDATION OF SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS DETERMINATION OF PREDNISOLONE ACETATE AND OFLOXACIN IN EYE-DROP
The present manuscript describes simple, sensitive, rapid, accurate, precise and economical spectrophotometric method for the simultaneous determination of prednisolone acetate and ofloxacin in combined eye drop dosage form. The method is based on the simultaneous equations method for analysis of both the drugs using methanol as solvent. Prednisolone acetate has absorbance maxima at 243 nm and ofl...
DETERMINATION OF PIOGLITAZONE HYDROCHLORIDE IN BULK AND PHARMACEUTICAL FORMULATIONS BY UV SPECTROPHOTOMETRIC METHOD
UV spectrophotometric method was developed and validated for the analysis of pioglitazone in tablets. The analyses were performed in Phosphate buffer (pH 7.4). Beer’s law was valid in concentration range of 10-50 mcg/ml and UV detection was done at 238 nm. The developed method was validated respect to linearity, precision, accuracy, selectivity / sensitivity applied to the determination of Piogl...
EVALUATION OF ANXIOLYTIC ACTIVITY OF HYDROALCOHOLIC ACTIVITY OF TEPHROSIA PURPURIA (L) PERS ON SWISS ALBINO MICE
The present work is to evaluate the anxiolytic activity of a hydroalcoholic extract of Tephrosia purpuria (L) Pers (HAETP) in mice using the elevated plus-maze (EPM), elevated zero-maze (EZM), Y-maze and hole-board models. Furthermore, the anxiolytic effects of HAETP were compared to a known active anxiolytic drug diazepam. The extract, administered orally, in two different doses of HAETP 200 mg/k...
Amlodipine is the third generation calcium antagonist, 1,4-dihydropyridine derivative with the prolonged duration of the antihypertensive action, especially blocking L-type Ca2+ ion channels. It promotes beneficial therapeutic effect by coronary and other blood vessel diseases and thus delays development of the atherosclerosis. It has several known trade names, the most mentioned is Norvasc. Amlod...
