modified by varying its side chain. In this study, we synthesized Q203 analogues with different side chains and studied their effects on anti-tubercular activity. Many analogues showed good potency against M. tuberculosis replicating in liquid broth culture medium (extracellular activity) regardless of chain length and conformational changes. However, a polar character in the side chain region was unfavorable
6-氯-2-乙基-N-(4-(4-(4-(三氟甲氧基)苯基)哌啶-1-基)苄基)咪唑并[1,2- a ]吡啶-3-的抗结核活性羧酰胺(Q203)通过改变其侧链进行修饰。在这项研究中,我们合成了具有不同侧链的Q203类似物,并研究了它们对抗结核活性的影响。许多类似物对M显示出良好的效力。结核菌在液体肉汤培养基中复制(细胞外活性),而与链长和构象变化无关。但是,侧链区域的极性特征不利于抗结核活性。的类似物,25,28,35和36,对M表现出出色的活性。结核在巨噬细胞内部复制(细胞内活性),并具有较高的药物暴露水平和较长的半衰期,具有良好的药代动力学(PK)特性。
