Abstract

Mycobacterium tuberculosis infections still pose a serious threat to human health. Combination therapies are effective medical solutions to the problem. Mycobacterium tuberculosis is an intracellular pathogen that mainly depends on a virulence factor (Mycobacterium tuberculosis protein tyrosine Phosphatase B, MptpB) for its survival in the host. Therefore, MptpB inhibitors are potential components of tuberculosis combination treatments. Herein, a new series of MptpB inhibitors bearing a rhodanine group were developed using a structure-based strategy based on the virtual screening hit. The new MptpB inhibitors displayed potent MptpB inhibitory activities and great improvements in cell membrane permeability. The optimal compounds reduced the Bacterial burden in a dose-dependent manner in a macrophage Infection model, especially, a combination of compound 20 and rifampicin led to a Bacterial burden reduction of more than 95%, greater than the reductions achieved with compound 20 or rifampicin alone. This research provides new insights into the rational design of new MptpB inhibitors and verifies that the MptpB inhibitor has a promising potential as a component of tuberculosis treatment.
