In the present work, twenty-five nicotinoyl pyrazoline derivates bearing N-methyl indole moiety have been designed and synthesized. The biological evaluation of these compounds as tubulin assembly inhibitors revealed that most of them were potential antitumor agents. Among them, compound 28 exhibited most potency against cancer cell line panels (GI50 = 29–90 nM for HeLa, HepG2 and MCF-7 cells) without
在目前的工作中,已经设计并合成了二十五个带有N-甲基吲哚部分的烟酰基吡唑啉衍生物。这些化合物作为微管蛋白组装抑制剂的生物学评估表明,它们中的大多数是潜在的抗肿瘤药。其中,化合物28对癌细胞系的药效最大( 对于HeLa,HepG2和MCF-7细胞,GI 50 = 29–90 nM),对非肿瘤细胞无毒性( 对于293 T细胞,CC 50 > 300μM),结合到微管蛋白的秋水仙碱位点,并在微管蛋白组装试验中表现出出色的抑制活性(IC 50 = 1.6μM,优于CA-4)。进行了分子动力学模拟以验证化合物28的对接姿势与微管蛋白结晶。对HepG2和HeLa细胞的进一步研究表明,化合物28可能导致有丝分裂阻滞至G2 / M期,随后诱导细胞凋亡。还在HeLa异种移植裸鼠上评估了化合物28的体内效率,相对肿瘤抑制率高达61.52%,而没有明显的体重减轻和组织损伤(通过H&E染色检查),与CA-4相当(抑制59
