The article describes the design, synthesis, and characterization of a new series of 8‐trifluoromethylquinoline substituted pyrazole‐3‐carboxamides (9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h, 9i, 9j, 9k, 9l, 9m, 9n, 9o, 9p, 9q, 9r, 9s, 9t) derived from different primary and secondary amines. The intermediate and target compounds were characterized using spectroscopic methods. The structures of intermediate 7
本文介绍了一系列新的8-三氟甲基喹啉取代的吡唑-3-羧酰胺的设计,合成和表征(9a,9b,9c,9d,9e,9f,9g,9h,9i,9j,9k,9l,9m,9n,9o,9p,9q,9r,9s,9t)衍生自不同的伯胺和仲胺。使用光谱方法表征中间体和目标化合物。单晶X射线研究证明了中间体7和目标分子9d的结构。所有合成的目标化合物(9a,9b,9c,9d,9e,9f,9g,9h,9i,9j,9k,9l,9m,9n,9o,9p,9q,9R,9S,9吨)和三个中间体(6,7,8)被筛选其在体外对抗结核活性结核分枝杆菌ħ 37器Rv应变。两种化合物9k和9t表现出显着的抑制活性,MIC为3.13 µg / mL,与标准药物乙胺丁醇的活性相当。衍生自苄胺衍生物的羧酰胺比其苯胺类似物更具活性。通常,具有N-亚甲基键的杂化酰胺(-CONHCH 2‐)表现出增强的抗结核活性。在抗菌筛选中,中间体3-肼基-2
