decreased significantly if a chlorine or methoxy group replaced the fluorine atom. 3'-Fluoro-6-methoxy-2-phenyl-4-quinolone-3-carboxylic acid (68) had the highest in vitro cytotoxic activity among all tested carboxylic acid derivatives and their salts. The mechanism of action may be similar, but not identical, to that of tubulin binding drugs, such as navelbine and taxol. Compound 68 merits further investigation
作为对2-苯基-4-喹诺酮系列中潜在抗癌候选药物的持续搜索的一部分,合成并评估了3',6-取代的2-苯基-4-喹诺酮-3-羧酸衍生物及其盐。初步筛选显示,含有间氟取代的2-苯基的羧酸类似物具有最高的体外抗癌活性。如果氯或甲氧基取代氟原子,则活性会显着降低。在所有测试的羧酸衍生物及其盐中,3'-氟-6-甲氧基-2-苯基-4-喹诺酮-3-羧酸(68)的体外细胞毒性活性最高。作用机理可能与结合微管蛋白的药物(如纳韦宾和紫杉醇)相似但不相同。化合物68作为新型亲水抗有丝分裂剂值得进一步研究。
