influence of fluorine, in particular on the A-ring, a new series of fluoro analogues (7a–l) of phenstatin (3) was synthesized and tested for interactions with tubulin polymerization and evaluated for cytotoxicity on an NCI-60 human cancer cell lines panel. We have shown that the replacement of 3,4,5-trimethoxyphenyl A-ring of phenstatin with 2,4,5-trifluoro-3-methoxyphenyl unit, results in the conservation
为了研究氟的影响,尤其是对A环的影响,合成了一系列新的非他汀(3)的氟类似物(7a – l),并测试了其与微管蛋白聚合反应的相互作用,并评估了其对NCI的细胞毒性。 -60人癌细胞系面板。我们已经表明,用2,4,5-三氟-3-甲氧基苯基单元代替苯达他汀的3,4,5-三甲氧基苯基A-环,导致了抗微管蛋白和细胞毒性作用的保守。氟异康他汀7k是本研究中最有效的抗癌药,对白血病细胞SR(GI 50 = 15 nM)和HL-60(TB)(GI)具有最高的抗增殖潜力50 = 23 nM)和黑色素瘤细胞系MDA-MB-435(GI 50 = 19 nM)。
