carboxylic acid analogues have been synthesized, characterized and evaluated anti-proliferative activity against five human cancer cell lines such as A549 (lung cancer), Mia Paca (pancreatic cancer), HeLa (cervical cancer), MDA MB-231 (breast cancer), MCF-7 (breast cancer) and normal embryonic kidney cell line (HEK) were carried out using MTT assay. Few of the synthesized analogues exhibited potent
摘要在我们寻求扩大新的潜在抗癌药物的追求中,一系列18种新颖的1-环丙基-6-氟-4-氧代-7-(4-取代的哌嗪-1-基)-1,4-二氢喹啉-3-羧酸已合成,表征和评估了类似物对五种人类癌细胞系(例如A549(肺癌),Mia Paca(胰腺癌),HeLa(宫颈癌),MDA MB-231(乳腺癌),MCF-使用MTT分析进行了7(乳腺癌)和正常胚胎肾细胞系(HEK)的检测。很少有合成的类似物在较低浓度下对癌细胞系表现出有效的抗癌活性。与阿霉素相比,合成的化合物对正常人胚胎肾细胞系(HEK)的毒性较小。值得注意的是,化合物3o与环丙沙星相比,它对所有五个癌细胞系均表现出强大的活性。进一步的研究表明,化合物3o可以插入小牛胸腺DNA中,形成3o -DNA复合物,这可能会阻止DNA复制,从而发挥抗增殖活性。对接模拟研究得到了与II型DNA拓扑异构酶的分子相互作用的支持。这些衍生物可以成为潜在抗癌药物开发的先导结构。
