quinolone antibacterials are one of the most important classes of pharmacological agents known as potent inhibitors of bacterial dna gyrase and topoisomerase iv that efficiently inhibit dna replication and transcription by generating several double-stranded dna break. some quinolone derivatives demonstrated inhibitory potential against eukaryote topoismarase ii and substantial dose-dependent cy...

background: present investigations were carried out to evaluate an ethanolic extract of oxalis corniculata linn. for its anticancer and antioxidant activity in ehrlich acsites carcinoma (eac) - induced in swiss albino mice. methods: cancer was induced in mice by aspiration of peritoneal fluid of eac inoculated mice and diluted to get 1x10 6 cells/ml in phosphate buffer. cancerous animals were d...

substituted 1, 2, 4- triazoles have shown multiple biological activities such as anti-inflammatory, anti fungal, etc. 5-mercapto triazoles were prepared from the potassium dithiocarbazinates. these triazoles were used for preparation of different derivatives by two different schemes. in the first scheme the mannich bases were prepared from 5- marcapto-s triazole quinazolines. the 5-marcato-s-tr...
