Several potential inhibitors of mRNA guanine 7-methyltransferase, which were designed from mechanism-based considerations, were evaluated against the vaccinia virus capping enzyme complex. Of the compounds tested, 5'-deoxy-5'[6-(2-aminopyrrolo[2,3-d]-pyrimidine-4-one) methylthio]adenosine (9) had good selective inhibitory activity against vaccinia mRNA guanine 7-methyltransferase, exhibiting an IC50
从基于机制的考虑设计了几种潜在的鸟嘌呤7-甲基转移酶mRNA抑制剂,针对牛痘病毒加帽酶复合物进行了评估。在测试的化合物中,5'-脱氧-5'[6-(2-氨基吡咯并[2,3-d]-嘧啶-4-酮)甲硫基]腺苷(9)对牛痘mRNA鸟嘌呤7-具有良好的选择性抑制活性。甲基转移酶,IC50为9.2 X 10(-5)M。结构活性考虑因素表明,低分子量多底物加合物抑制剂对RNA甲基转移酶的特异性抑制作用是可以实现的。
