The synthesis of several new pyrazolo[3,4‐b]pyridine, pyrido[2',3':3,4]‐pyrazolo[1,5‐a]pyrimidine and imidazo[1',2':1,5]pyrazolo[3,4‐b]pyridine derivatives is described. The obtained compounds were tested for their antiproliferative activity in vitro. One of them, 4‐phenyl‐2‐(3,4,5‐trimethoxy‐β‐styrylo)pyrido[2',3':3,4]pyrazolo[1,5‐a]pyrimidine (9), revealed cytotoxic properties against the cells of
几种新型吡唑并[3,4-b]吡啶、吡啶并[2',3':3,4]-吡唑并[1,5-a]嘧啶和咪唑并[1',2':1,5]的合成描述了吡唑并[3,4-b]吡啶衍生物。测试所得化合物的体外抗增殖活性。其中之一,4-苯基-2-(3,4,5-三甲氧基-β-苯乙烯基)吡啶并[2',3':3,4]吡唑并[1,5-a]嘧啶(9),显示出细胞毒性对所有三种人类癌细胞系的细胞的特性都适用。另一种,2,4-二甲基-吡啶并[2',3':3,4]吡唑并[1,5-a]-嘧啶 (2),仅对人膀胱癌细胞系 HCV29T 的细胞显示出微弱的细胞毒活性. 测试的所有其他化合物均未显示任何细胞毒性活性。
