Identification of Antitubercular Benzothiazinone Compounds by Ligand-Based Design
摘要:
1,3-Benzothiazin-4-ones (BTZs) are a novel class of TB drug candidates with potent activity against M. tuberculosis. An in silico ligand-based model based on structure-activity data from 170 BTZ compounds was used to design a new series. Compounds were tested against a panel of mycobacterial strains and were profiled for cytotoxicity, stability, and antiproliferative effects. Several of the compounds showed improved activity against MDR-TB while retaining low toxicity with higher microsomal, metabolic, and plasma stability.

The compositions of the present disclosure provide novel fluorogenic probes for use in the specific imaging and detection of mycobacteria species, and in particular β-lactam-antibiotic resistant. Specificity for mycobacteria is conferred on these probes by incorporating a moiety that specifically targets the unique trapping mechanism of the DprE1 found in in mycobacteria. Accordingly, only Mycobacteria species that express both a β-lactamase and DprE1 enable both the activation of the caged fluorescent probe, and the affixing of the released fluorescent probes to the bacteria cells through the functioning reduction-covalent binding mechanism. Advantageously, such a probe is able, at its most sensitive, to allow single mycobacterium detection.
