  摘要：

  测试了几种8-取代的O6-苄基鸟嘌呤，2-和/或8-取代的6-（苄氧基）嘌呤，取代的6（4）-（苄氧基）嘧啶和6-（苄氧基）-s-三嗪的能力。使人类DNA修复蛋白O6-烷基鸟嘌呤-DNA烷基转移酶（AGT，烷基转移酶）失活。已鉴定出两种类型的化合物在使人HT29结肠肿瘤细胞提取物中的AGT失活方面比O6-苄基鸟嘌呤（原型低分子量灭活剂）明显更有效。它们是在8位带有吸电子基团的8-取代的O6-苄基鸟嘌呤（例如8-氮杂-O6-苄基鸟嘌呤和O6-苄基-8-溴鸟嘌呤）和5-取代的2,4-二氨基-6-（苄氧基）在5位带有吸电子基团的嘧啶（例如2,4-二氨基-6-（苄氧基）-5-亚硝基和2，4-二氨基-6-（苄氧基）-5-硝基嘧啶）。在完整的HT29结肠肿瘤细胞中，后者的衍生物在灭活AGT方面比O6-苄基鸟嘌呤更有效。如果这些类型的嘌呤和嘧啶没有表现出不希望的毒性，则它们可以优于O6-苄基鸟嘌呤作为用
