Derivatives of 2-chloro-2′-deoxyadenosine (1a) containing secondary 6-NH2 groups (5a-c) or a 8-Br substituent (9) were synthesized. They were tested together with ring-modified congeners containing a pyrrolo[2,3-b]pyridine, pyrrolo[3,2-c]pyridine, or pyrazolo[3,4-d]pyrimidine ring system as inhibitors of various leukemic cell lines. Only the 8-Br derivatives 9 showed inhibitory activity, whereas the
合成了含有仲6-NH 2基团(5a-c)或8-Br取代基(9)的2-氯-2'-脱氧腺苷(1a)的衍生物。将它们与含有吡咯并[2,3- b ]吡啶,吡咯并[3,2- c ]吡啶或吡唑并[3,4- d ]嘧啶环系统作为各种白血病细胞系抑制剂的环修饰同类物一起进行了测试。。仅8-Br衍生物9表现出抑制活性,而碱基修饰的同类物没有活性。化合物1a在ap K a = 1.4(2'-脱氧腺苷在p K a= 3.8)。质子化发生在N(7),而不是在dA观察到的N(1)。
