useful antitumor drugs, thiocolchicine derivatives, including their phosphate and other water soluble salts, were synthesized and evaluated for inhibition of tubulin polymerization and for in vitro cytotoxicity. Three compounds, 7, 10, and 11, showed potent inhibition of tubulin assembly (IC50 = 0.88–1.1 μM). In addition, compound 7, a water soluble succinic acid salt of N-deacetylthiocolchicine (4), showed
作为我们继续研究秋水仙素类作为治疗上有用的抗肿瘤药物的一部分,硫代秋水仙素衍生物,包括它们的磷酸盐和其他水溶性盐,被合成并评估了抑制微管蛋白聚合和体外细胞毒性。三种化合物,7,10,和11,表现出微管蛋白的强效抑制组件(IC 50 = 0.88-1.1μM)。此外,化合物7,一种N-脱乙酰硫代秋水仙碱 ( 4 ) 的水溶性琥珀酸盐,对一组肿瘤细胞系显示出有效的细胞毒性,表明它可能是开发作为治疗性抗肿瘤剂的潜在线索。化合物8N , N-二甲基-N-脱乙酰硫代秋水仙碱 ( 5 ) 的水溶性琥珀酸盐显示出对 HCT-8 和 SK-BR-3 细胞的选择性活性。N , N-二乙基-N-脱乙酰硫代秋水仙碱( 6 ) 似乎不是 P-gp 外排泵的底物,基于对 P-gp 过表达 KBvin (0.0146 μg/mL) 细胞获得的相似 ED 50值和亲本 KB (0.0200 μg/mL) 细胞系。
