inhibitors of the enzyme can be designed and synthesised with the aim of being developed into novel anti-parasitic drugs. Analogue based design was used to target the Plasmodium falciparum dUTPase (PfdUTPase). The structures of previously discovered selective inhibitors of the PfdUTPase were modified by insertion of an amide bond. A series of tritylated uracil acetamide derivatives were synthesised
普遍存在的酶dUTP核苷酸水解酶(dUTPase)催化dUTP水解为dUMP,可以被视为抵制尿嘧啶掺入DNA的第一道防线。抑制这种酶会导致尿嘧啶过度掺入DNA中,导致DNA片段化和细胞死亡,因此具有致死性。通过利用人和疟原虫dUTPase之间的结构差异,可以设计和合成该酶的选择性抑制剂,以开发为新型抗寄生虫药物。基于类似物的设计用于靶向恶性疟原虫dUTPase(Pf dUTPase)。先前发现的Pf选择性抑制剂的结构dUTPase通过插入酰胺键进行修饰。合成了一系列三苯甲基化的尿嘧啶乙酰胺衍生物,并评价了其对体外酶和寄生虫生长的抑制作用。这些化合物是Pf dUTPase的弱抑制剂。
