Abstract
Tuberculosis (TB) is a chronic infectious disease, which is caused by the pathogen Mycobacterium tuberculosis (Mtb) and reemerged as a global health risk with a significant proportion of multi-drug resistant and extensively drug resistant TB cases. It is very urgent to find some novel high-confidence drug targets in Mtb for discovering the effective anti-TB agents. Thioredoxin reductase (TrxR) has been identified to be a highly viable target for anti-TB drugs for its important role in protecting the pathogen from thiol-specific oxidizing stress, regulating intracellular dithiol/disulfide homeostasis and DNA replication and repair. In the present work, a near-infrared (NIR) fluorescent probe DDAT was developed for the detection of TrxR activity and used to high-throughput screen the TrxR inhibitors from natural products. Two screened TrxR inhibitors from Sappan Lignum and microbial metabolites that were further used to inhibit Mycobacterium tuberculosis. All the results indicate that DDAT is a practical fluorescent molecular tool for the discovery of potential anti-TB drugs.
