The present study describes comprehensive stress testing of febuxostat under different prescribed ICH stress conditions, and a stability-indicating reverse phase novel ultra-performance liquid chromatographic (UPLC) assay was established. It was found capable of giving faster retention times, requiring minimal solvent and maintaining good resolution.(More)
The aim of this study was to investigate the effect of Morin on the pharmacokinetics of Piracetam in rats, in vitro enzyme kinetics and metabolic stability (high throughput) studies using human liver microsomes in UPLC. For pharmacokinetics studies, male Wistar rats were pretreated with Morin (10 mg/kg) for one week and on the last day, a single dose of(More)
A series of 3-(benzo[d]isoxazol-3-yl)-N-substituted pyrrolidine-2, 5-dione (7a-7d, 8a-8d, 9a-9c) have been prepared and evaluated for their anticonvulsant activities. Preliminary anticonvulsant activity was performed using maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) tests after intraperitoneal (ip) injection into mice, which are(More)
BACKGROUND Due to wide consumption of flavonoids in the dietary supplement, and an imperative role of CYPs and P-glycoprotein inhibition in drug disposition. So there is increasing scientific interest in drug-flavonoid interactions. OBJECTIVE The present study aims to investigate the effect of morin, a flavonoid, on the pharmacokinetics of febuxostat in(More)
A series of 3-[{5-(substituted-phenyl)-3-(phenyl/4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl}carbonyl]quinoxalin-2-ol derivatives (3–24) were synthesized by reacting 2-hydroxy quinoxaline-3-hydrazide with different substituted 1,3-diphenyl prop-2-en-1-ones in absolute ethanol. The structures of all the compounds were established on the basis of spectral(More)
Malaria is the leading infectious disease found in humans, affecting third-world countries. Worldwide, more than two billion people are at risk of malaria, with about 500 million clinical cases of malaria each year and one million deaths. In this focused review, an effort has been made to summarize the reactions of singlet oxygen with organic substrates,(More)
Piracetam was subjected to the hydrolytic, oxidative, thermal and photolytic stress, according to ICH guideline Q1A (R2). The drug depicted degradation only in basic conditions, while it was stable to other stress conditions (acidic, neutral hydrolysis, thermal and photolytic conditions). A total of one degradation product was formed, which were separated(More)
A rapid bioanalytical method was evaluated for the simultaneous determination of piracetam and its metabolite (M1) in human microsomal preparations by fast ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS). In addition, a validated method of M1 in rat plasma was developed and successfully applied on pharmacokinetic studies. The(More)
A series of (Z)-N-(1-(2-(2-amino-3-((dimethylamino) methyl) phenyl)-5-phenyl-1,3,4,oxadiazol-3(2H)- yl)ethanone derivatives was prepared and studied for its antimicrobial and antioxidant activities. Among the synthesized derivatives, compounds (7c) (Z)-N-(1-(2-(2-amino-3-((dimethylamino)methyl)phenyl)-5-phenyl-1,3,4-oxadiazol-3(2H)-(More)
