We synthesized the novel seco cyclopropa[c]pyrrolo[3,2-e]indole (CPI) bisalkylators and evaluated their antitumor activity. Among these derivatives, 11a (AT-760), in which the two seco 3-methoxycarbonyl-2-trifluoromethyl CPI (MCTFCPI) moieties are connected with a 3,3'-(1,4-phenylene)bisacryloyl group, was found to exhibit more potent cytotoxicity and antitumor activity against HeLaS3 human uterine
我们合成了新型山高环丙烷[c]吡咯并[3,2-e]吲哚(CPI)双烷基化剂并评估了其抗肿瘤活性。在这些衍生物中,发现其中11a(AT-760)的两个Seco 3-甲氧基羰基-2-三氟甲基CPI(MCTFCPI)部分与3,3'-(1,4-亚苯基)双丙烯酰基相连。分别对HeLaS3人子宫颈癌细胞和结肠26腺癌细胞具有比8(bizelesin,U-77,779)更强的细胞毒性和抗肿瘤活性。还显示出与化合物8或丝裂霉素C(MMC)相比,化合物11a在人结肠CX-1模型中表现出改善的体内功效。发现11a的有效剂量比8a的有效剂量低2倍。
