5‐styryl‐oxathiazol‐2‐ones as inhibitors of the Mycobacterium tuberculosis (Mtb) proteasome. As part of the study, the structure–activity relationship of oxathiazolones as Mtb proteasome inhibitors has been investigated. Furthermore, the prepared compounds displayed a good selectivity profile for Mtb compared to the human proteasome. The 5‐styryl‐oxathiazol‐2‐one inhibitors identified showed little activity
这是5-苯乙烯基草并恶唑-2-酮类药物作为结核分枝杆菌(Mtb)蛋白酶体抑制剂的首次报道。作为研究的一部分,已研究了草硫唑酮作为Mtb蛋白酶体抑制剂的构效关系。此外,与人蛋白酶体相比,制备的化合物对Mtb表现出良好的选择性。鉴定出的5-styryl-oxathiazol-2-one抑制剂对复制Mtb几乎没有活性,但对非复制细菌具有快速杀菌作用。(E)‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ 4 ‐‐‐‐‐‐‐‐yré‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ was ‐‐‐‐‐‐‐‐‐‐一was- ‐‐‐‐‐‐‐‐‐‐‐‐ 4?-‐‐‐‐‐‐‐‐‐‐‐‐‐‐5å?-‐‐‐‐‐‐‐‐‐‐‐‐ was?-‐‐‐‐‐‐‐‐‐‐‐‐waså?-‐‐‐ 5-(4-Chlorostyryl)‐1,3,4-Oxathiazol−2-1?的效果最佳,在所有测试浓度下的集落形成单位(CFU)/ mL仅在小于
