In search of novel purine antimetabolites, a series of 8‐substituted methylxanthine derivatives was prepared in order to explore their in vitro anticancer, anti‐HIV‐1 and antimicrobial activities. The target compounds include: 8‐[(3‐substituted‐4‐oxo‐thiazolidin‐2‐ylidene)hydrazino]‐1,3‐dimethyl (or 1,3,7‐trimethyl)‐3,7‐dihydropurine‐2,6‐diones 5a–e, 8‐[(3,4‐disubstituted 2,3‐dihydrothiazol‐2‐ylidene)hydrazino]‐1
在寻找新型嘌呤抗代谢物的过程中,制备了一系列 8-取代甲基黄嘌呤衍生物,以探索其体外抗癌、抗 HIV-1 和抗菌活性。目标化合物包括:8-[(3-取代-4-氧代-噻唑啉-2-亚基)肼]-1,3-二甲基(或1,3,7-三甲基)-3,7-二氢嘌呤-2, 6 - 二酮 5a - e, 8 - [(3,4 - 二取代的 2,3 - 二氢噻唑 - 2-亚基) 肼] -1,3,7 - 三甲基 - 3,7 - 二氢嘌呤 - 2,6 - 二酮 6a- d 和 8-(5-氨基-3-芳基吡唑-1-基)-1,3-二甲基-(或1,3,7-三甲基)-3,7-二氢嘌呤-2,6-二酮7a-g。体外抗癌结果显示,化合物5d对白血病K-562表现出超敏感性谱,GI50值<0.01 μM。化合物7c对结肠癌HCT-15和肾癌CAKI-1表现出显着的活性(GI50值为0.47和0.78 μM,分别)。化合物 7a 对结肠癌 HCT-15
