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). Synthesis and evaluation of alpha-thymidine analogues as novel antimalarials.,Cui H, Carrero-Lerida J, Silva AP, Whittingham JL, Brannigan JA, Ruiz-Perez LM, Read KD, Wilson KS, Gonzalez-Pacanowska D, Gilbert IH J Med Chem. 2012 Dec 27;55(24):10948-57. doi: 10.1021/jm301328h.
