  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.

  本公开的组合物提供了新型荧光探针，可用于分枝杆菌，尤其是抗β-内酰胺类抗生素分枝杆菌的特异性成像和检测。这些探针加入了一个分子，专门针对分枝杆菌中 DprE1 的独特捕获机制，从而对分枝杆菌具有特异性。因此，只有同时表达 β-内酰胺酶和 DprE1 的分枝杆菌才能激活笼式荧光探针，并通过有效的还原-共价结合机制将释放的荧光探针粘附到细菌细胞上。更有利的是，这种探针的灵敏度最高，可用于单个分枝杆菌的检测。
