Thio analogues of purine, pyridine, and pyrimidine were prepared based on the initial activity screening of several analogues of these heterocycles against Mycobacterium tuberculosis (Mtb). Certain 6-thio-substituted purine analogues described herein showed moderate to good inhibitory activity. In particular, two purine analogues 9-(ethylcarboxymethyl)-6-(decylthio)9H-purine (20) and 9-(ethylcarboxymethyl)-6-(dodecylthio)-9H-purine (21) exhibited MIC values of 1.56 and 0.78 mug/mL respectively against the Mtb H(37)Rv strain. N-9-Substitution apparently enhances the antimycobacterial activity in the purine series described herein.

Purine-derived covalent probes (e.g., halo or di-halo-substituted purine based covalent probes) and related ligands are described. The compounds can be used to identify reactive nucleophilic amino acid residues, such as reactive cysteine residues, in proteins and to modify the activity of proteins with reactive nucleophilic amino acid residues (e.g., reactive cysteine residues) via the formation of protein adducts comprising the ligands. Modified proteins prepared from the probes and ligands are also described.
