Plasmodium falciparum thymidylate kinase (PfTMPK) is a key enzyme in pyrimidine nucleotide biosynthesis. 3-Trifluoromethyl-4-chloro-phenyl-urea-α-thymidine has been reported as an inhibitor of Mycobacterium tuberculosis TMPK (MtTMPK). Starting from this point, we designed, synthesized and evaluated a number of thymidine analogues as antimalarials. Both 5′-urea-α- and β-thymidine derivatives were moderate
恶性疟原虫胸苷酸激酶 ( Pf TMPK) 是嘧啶核苷酸生物合成的关键酶。3-Trifluoromethyl-4-chloro-phenyl-urea-α-thymidine 已被报道为结核分枝杆菌TMPK ( Mt TMPK)的抑制剂。从这一点出发,我们设计、合成并评估了许多作为抗疟药的胸苷类似物。5'-尿素-α-和β-胸苷衍生物都是Pf TMPK 的中度抑制剂,并且还显示出对寄生虫生长的中度抑制。几种酶-抑制剂复合物的结构为改进抑制剂设计提供了基础。然而,我们发现某些 5'-尿素-α-胸苷类似物具有抗疟活性,其中PfTMPK 不是主要的作用方式。该系列的优化产生了具有有效抗疟活性的化合物(EC 50 = 28 nM;CC 50 = 29 μM)。
