چکیده

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 cytotoxic potential against some cancerous cells. in present study, synthesis and cytotoxic activity evaluation of new series of n-pipearzinyl quinolones containing n-2-(furyl-2 or 3-yl)-2-(chlorobenzyloxyimino) ethyl moiety 7a-i have been studied. reaction of quinolone, with 2-bromo-1-(furan-2 or 3-yl)ethanone-o-substituted chlorobenzyloxime in dmf in presence of nahco3 at room temperature, gave the title compounds n-2-(furan-2 or 3-yl)-2-(chlorobenzyloxyiminoethyl) quinolone 7a-i. synthesized compounds were further evaluated in-vitro against three human breast tumor cell lines. preliminary screening indicated that compound 7 g demonstrated significant growth inhibitory potential against all evaluated cell lines. the results of structure-activity relationship study exhibited that quinolone derivatives are superior in cytotoxic potential compared to 1, 8-naphthyridone series. furthermore, ethyl quinolone derivatives were more potent cytotoxic agents comparing with cyclopropyl quinolones.

Functionalized N(2-oxyiminoethyl) piperazinyl quinolones as new cytotoxic agents.

PURPOSE The prokaryotic type II topoisomerases (DNA gyrase and topoisomerase IV) and the eukaryotic type II topoisomerases represent the cellular targets for quinolone antibacterial agents and a wide variety of anticancer drugs, respectively. In view of the mechanistic similarities and sequence homologies exhibited by the two enzymes, tentative efforts to selectively shift from an antibacterial...

Synthesis and Cytotoxic Evaluation of Novel 3-Substituted Derivatives of 2-Indolinone

     The assessment of the degree or rate of cellular proliferation and cell viability is critical for the assessment of the effects of drugs on both normal and malignant cell populations. In the present study, a few novel 3-substituted derivatives of 2-indolinones were synthesized by condensation of substituted oxindole or isatin derivatives with appropriate aldehydes or primary aromatic amine...
