= 16–64 µg/mL). In silico docking study revealed the enoyl-acyl carrier protein reductase (InhA) and anthranilate phosphoribosyltransferase as potential molecular targets for the indolizines. The X-ray diffraction analysis of the compound 4b was also carried out. Further, a safety study (in silico and in vitro) demonstrated no toxicity for these compounds. Thus, the indolizines warrant further development
摘要 筛选了一系列 1,2,3-三取代的吲哚嗪(2a-2f、3a-3d和4a-4c)对敏感 H37Rv 和耐多药 (MDR)结核分枝杆菌的体外全细胞抗结核活性(MTB) 菌株。化合物2b–2d、3a–3d和4a–4c对 H37Rv-MTB 菌株具有活性,最小抑制浓度 (MIC) 范围为 4 到 32 µg/mL,而吲哚嗪4a–4c具有乙基酯基团苯甲酰基环的 4 位也表现出抗 MDR-MTB 活性(MIC = 16–64 µg/mL)。电脑模拟对接研究表明,烯酰-酰基载体蛋白还原酶(InhA)和邻氨基苯甲酸磷酸核糖转移酶是吲哚嗪的潜在分子靶标。还进行了化合物4b的X射线衍射分析。此外,一项安全性研究(计算机和体外)证明这些化合物没有毒性。因此,indolizine 需要进一步开发,并且可能代表一类新的有前途的 InhA 抑制剂和多靶向药物,以对抗药物敏感和耐药的 MTB 菌株。
