New series of 2-(2-arylidenehydrazinyl)pyrido[2,3-d]pyrimidines 5a–e and pyrido[2,3-d][1,2,4]triazolo[4,3-a]pyrimidines 6–15 were synthesized and evaluated for their cytotoxic activity against two cancer cell lines, namely PC-3 prostate cancer and A-549 lung cancer. Some of the tested compounds displayed high growth inhibitory activity against PC-3 cells. Whereas, compounds 5b and 15f showed relatively
新系列(2- arylidenehydrazinyl)吡啶并[2,3-的d ]嘧啶5A - ë和吡啶并[2,3- d ] [1,2,4]三唑并[4,3一]嘧啶6 - 15合成并评估它们对两种癌细胞系,即PC-3前列腺癌和A-549肺癌的细胞毒活性。一些测试的化合物显示出对PC-3细胞的高生长抑制活性。而化合物5b和15f显示出对PC-3和A-549细胞系相对有效的抗肿瘤活性。特别是4-(3-乙酰基-5-氧代-6-苯基-8-(噻吩-2-基)吡啶基[2,3- d ] [1,2,4]三唑并[4,3- a] pyrimidin-1(5 H)-基)苯磺酰胺15f在亚微摩尔水平下(IC 50 分别为0.36、0.41μM)对两种细胞系均表现出优异的抗肿瘤活性。此外,研究了有前途的化合物15f对更敏感的细胞系PC-3的细胞毒活性的潜在机制。数据表明15f能够至少部分地通过提高细胞周期抑制剂p21的表达水
