of heterocyclic derivatives with potential anticancer activity, in which a pyrrolo[1,2-b]pyridazine or a pyrrolo[2,1-a]phthalazine moiety was introduced in place of the 3′-hydroxy-4′-methoxyphenyl ring of phenstatin have been synthesised and their structure-activity relationship (SAR) was studied. Fourteen of the new compounds were evaluated for their in vitro cytotoxic activity by National Cancer Institute
摘要 两个具有潜在抗癌活性的新杂环衍生物系列,其中引入吡咯并[1,2- b ]哒嗪或吡咯并[2,1- a ]酞嗪部分代替3'-羟基-4'-甲氧基苯基合成了苯司他丁环并研究了它们的构效关系(SAR)。美国国家癌症研究所 (NCI) 针对 60 种人类肿瘤细胞系评估了 14 种新化合物的体外细胞毒活性。在第二阶段五剂量反应研究中筛选了体外生长抑制方面最好的五种化合物,其中三种对结肠、卵巢、肾、前列腺等多种细胞系显示出非常好的抗增殖活性,GI 50 <100 nM 、脑癌和乳腺癌、黑色素瘤和白血病。生物活性化合物的对接实验显示与微管蛋白秋水仙碱结合位点具有良好的相容性。
