2-Phenyl-4-quinolone acetic acids and their esters were synthesized and evaluated for interaction with tubulin and for cytotoxicity against a panel of human tumor cell lines. 2-Phenyl- and 2-(2'-fluorophenyl)-4-quinolone-8-acetic acids (11 and 12) displayed potent cytotoxicity with ED(50) values at nanomolar concentrations, but had minimal activity against tubulin polymerization. 2-(2'-Fluoropheny
合成了2-苯基-4-喹诺酮乙酸及其酯,并评估了与微管蛋白的相互作用以及对一组人类肿瘤细胞系的细胞毒性。2-苯基和2-(2'-氟苯基)-4-喹诺酮-8-乙酸(11和12)在纳摩尔浓度下显示出强的细胞毒性和ED(50)值,但对微管蛋白聚合的活性却最小。2-(2'-氟苯基)-4-喹诺酮-6-乙酸(3)和2-(2'-氟苯基)-4-喹诺酮-8-乙酸甲酯(10)适度抑制微管蛋白聚合。
