The benzo[d]thiazol-2-yl(piperazin-1-yl)methanones scaffold has been identified as new anti-mycobacterial chemotypes. Thirty-six structurally diverse benzo[d]thiazole-2-carboxamides have been prepared and subjected to assessment of their potential anti-tubercular activity through in vitro testing against Mycobacterium tuberculosis H37Rv strain and evaluation of cytotoxicity against RAW 264.7 cell lines
苯并[ d ]噻唑-2-基(哌嗪-1-基)甲烷酮支架已被鉴定为新的抗分枝杆菌化学型。已经制备了三十六种结构多样的苯并[ d ]噻唑-2-羧酰胺,并通过针对结核分枝杆菌H 37 Rv菌株的体外测试以及针对RAW 264.7细胞系的细胞毒性评估了其潜在的抗结核活性。十七种化合物显示出具有低(1–10)μM范围的MIC的抗分枝杆菌潜力。5-三氟甲基苯并[ d] thiazol-2-yl(piperazin-1-yl)methanenes成为最有希望的结果,可产生6个阳性结果(2.35-7.94μM),并且具有低细胞毒性(在50μg/ mL浓度下抑制率小于50%)。这些命中的治疗指数为8–64。建立了定量结构活性关系,采用显示出高预测性的统计可靠的CoMFA模型([Rp[RËd2个=0.718,[RñCv2个=0.995)。
