attempt to develop potent antitumor agents, new rhodacyanine analogues containing the pyridinium ring ( 5a – 5h ), the isoquinolinium ring ( 6a – 6c ) and the quinolinium ring ( 7a – 7e ) linked to the rhodanine ring via N–N covalent bond were designed, synthesized and evaluated for antitumor activity against human lung cancer cell line (H460) by MTT assay in vitro . Most of the tested compounds showed enhanced
摘要为了开发有效的抗肿瘤药物,新的含有酪氨酸环(5a-5h),异喹啉鎓环(6a-6c)和喹啉鎓环(7a-7e)的若丹菁类似物通过N–N共价键与罗丹宁环连接通过MTT法体外设计,合成并评价了对人肺癌细胞系(H460)的抗肿瘤活性。与先导化合物MKT-077相比,大多数测试化合物显示出增强的抗肿瘤活性,IC 50值为0.006至9.2μmol/ L。其中,最有前途的化合物7d(IC 50 = 0.006μmol/ L)的活性是MKT-077(IC 50 = 1.3μmol/ L)的216.7倍。讨论了目标化合物的初步结构-活性关系。
