A series of 2-(tetrazol-5-yl)sulfonylacetamide derivatives were synthesized and evaluated for their in vitro inhibitory activity against Mycobacterium tuberculosis (Mtb) and Mycobacterium marinum (Mm). The most active compounds exhibited in vitro MIC90 values of 1.25 μg/mL against Mtb, but they were less effective against Mm (MIC90 ≥ 10 μg/mL). Despite the most active compounds having favourable physicochemical
合成了一系列2-(四唑-5-基)磺酰基乙酰胺衍生物,并评估了其对结核分枝杆菌(Mtb)和海分枝杆菌(Mm)的体外抑制活性。最活跃的化合物对 Mtb 的体外MIC 90值为 1.25 μg/mL,但对 Mm 的效果较差(MIC 90 ≥ 10 μg/mL)。尽管最活跃的化合物具有良好的理化性质,其中一种与小鼠肝微粒体一起孵育时的半衰期约为 3 小时,但两种代表性的高活性化合物对半胱氨酸衍生物表现出强烈的化学反应性,作为体内替代物以硫为中心的亲核试剂,表明亲电性过高,因此可能在体内发生不加区别的化学反应,代表一般毒性的不可接受的高风险,并且治疗有效的可能性很低。
