Function

KTHY_PLAF7 Catalyzes the phosphorylation of thymidine monophosphate (dTMP) to thymidine diphosphate (dTDP), the immediate precursor for the DNA building block dTTP (PubMed:18477629, PubMed:19126267, PubMed:31934749, PubMed:20353400). Can also phosphorylate dGMP and to a lesser extent GMP, dUMP and dIMP (PubMed:18477629, PubMed:19126267, PubMed:31934749, PubMed:20353400). Can use either ATP or dATP as phosphate donors in presence of Mg(2+) (PubMed:18477629).^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Plasmodium falciparum thymidylate kinase (PfTMPK) is a key enzyme in pyrimidine nucleotide biosynthesis. 3-Trifluoromethyl-4-chloro-phenyl-urea-alpha-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-alpha- and beta-thymidine derivatives were moderate inhibitors of PfTMPK and furthermore showed moderate inhibition of parasite growth. The structure of several enzyme-inhibitor complexes provides a basis for improved inhibitor design. However, we found that certain 5'-urea-alpha-thymidine analogues had antimalarial activity where inhibition of PfTMPK is not the major mode of action. Optimization of this series resulted in a compound with potent antimalarial activity (EC(50) = 28 nM; CC(50) = 29 muM).
