Deoxyuridine 5'-triphosphate nucleotidohydrolase (dUTPase) is a potential drug target for malaria. We previously reported some 5'-tritylated deoxyuridine analogues (both cyclic and acyclic) as selective inhibitors of the Plasmodium falciparum dUTPase. Modelling studies indicated that it might be possible to replace the trityl group with a diphenyl moiety, as two of the phenyl groups are buried, whereas
脱氧尿苷5'-三磷酸核苷酸水解酶(dUTPase)是疟疾的潜在药物靶标。我们先前报道了一些5'-三苯甲基化的脱氧尿苷类似物(环状和无环的)作为恶性疟原虫dUTPase的选择性抑制剂。模型研究表明,由于两个苯基被掩埋,而第三个苯基暴露于溶剂,则可能有可能用二苯基部分取代三苯甲基。本文中,我们报告了一些亲脂性和分子量均低于三苯甲基铅化合物的二苯类似物的合成和评估。共晶体结构表明,二苯基抑制剂以类似的方式与相应的三苯甲基衍生物结合,其中两个苯基部分占据了预测的掩埋苯基结合位点。
