Our previous exploration of 2-phenylquinolin-4-ones (2-PQs) has led to an anticancer drug candidate 2-(2-fluorophenyl)-6,7-methylenedioxyquinolin-4-one monosodium phosphate (CHM-1−P-Na). In order to develop additional new drug candidates, novel 2-PQs were designed, synthesized, and evaluated for cytotoxic activity. Most analogues, including 1b, 2a,b, 3a,b, 4a,b, and 5a,b, exhibited significant inhibitory
我们之前对2-苯基喹啉-4-酮(2-PQs)的探索已导致候选抗癌药物2-(2-氟苯基)-6,7-亚甲基二氧基喹啉-4-酮磷酸一钠(CHM-1-P-Na )。为了开发其他新的候选药物,设计,合成并评估了新型2-PQ的细胞毒性活性。大多数类似物,包括1b,2a,b,3a,b,4a,b和5a,b,均对所有测试的肿瘤细胞系表现出显着的抑制活性(IC 50为0.03-8.2μM)。作为最有效的类似物之一,2-(3-氟苯基)-5-羟基-6-甲氧基喹啉-4-酮(3b)在美国国家癌症研究所(NCI)的评估中选择性抑制了60个癌细胞系中的14个。初步的作用机制研究表明3b对胰岛素样生长因子1受体(IGF-1R)的酪氨酸自磷酸化有显着影响。3b的安全药理学分析表明,对大多数测试酶的正常生物学功能均无明显影响。此外,磷酸3b的2-(3-氟苯基)-6-甲氧基-4-氧代-1,4-二氢喹啉-5-基磷酸钠(15)超过了阿霉素的活性,可与CHM-1媲美。
