Synthesis and inhibitory activity of thymidine analogues targeting Mycobacterium tuberculosis thymidine monophosphate kinase.

Abstract : We report on Mycobacterium tuberculosis thymidine monophosphate kinase (TMPKmt) inhibitory activities of a series of new 3'- and 5'-modified thymidine analogues including α- and β-derivatives. In addition, several analogues were synthesized in which the 4-oxygen was replaced by a more lipophilic sulfur atom to probe the influence of this modification on TMPKmt inhibitory activity. Several compounds showed an inhibitory potency in the low micromolar range, with the 5'-arylthiourea 4-thio-α-thymidine analogue being the most active one (K(i)=0.17μM). This compound was capable of inhibiting mycobacteria growth at a concentration of 25μg/mL.
