Summary: | UDP-galactopyranose mutase (UGM) is an essential enzyme involved in the bacterial cell wall synthesis, and is not present in mammalian cells. Thus, UGM from
(
) represents a novel and attractive drug target for developing antituberculosis agents. A pyrazole-based compound,
, was previously identified as a mixed inhibitor of
UGM which targets an allosteric site. To understand more about the structure activity relationship around the
scaffold as a
UGM inhibitor, thirteen pyrazoles and triazole analogues were synthesized and tested against both
UGM and
in vitro. While the introduced structural modifications to
did not improve the antituberculosis activity, most of the compounds showed
UGM inhibitory activity. Interestingly, the pyrazole derivative
showed a competitive model for
UGM inhibition with improved Ki value of 51 ± 4 µM. However, the same compound did not inhibit the growth of
