= 2.06 μM), which are the most potent and selective noncarbohydrate-based inhibitors toward gal-3/8 isoforms to date. The molecular docking investigations suggested that the unique amino acids Arg144 in galectin-3 and Ser213 in galectin-8C could contribute to their potency and selectivity. The scratch wound assay demonstrated that Cpd53 and Cpd57 were able to inhibit the MRC-5 lung fibroblast cells
半乳糖凝集素 3 和半乳糖凝集素 8 均通过识别含半乳糖的糖蛋白参与细胞粘附、迁移、凋亡、血管生成和炎症过程。抑制半乳糖凝集素 3/8 活性是治疗癌症和组织纤维化的潜在方法。在此,一系列新型N-芳基磺酰基-5-芳氧基-吲哚-2-甲酰胺衍生物被公开为半乳糖凝集素 3 和半乳糖凝集素 8 C 端结构域的双重抑制剂,具有低微摩尔水平的K d值(Cpd 53 , gal -3: K d = 4.12 μM,gal-8C: K d = 6.04 μM;Cpd 57 ,gal-3: K d = 12.8 μM,gal-8C: K d = 2.06 μM),它们是最有效和选择性的迄今为止针对 gal-3/8 亚型的非碳水化合物抑制剂。分子对接研究表明,galectin-3 中的独特氨基酸 Arg144 和 galectin-8C 中的 Ser213 可能有助于其效力和选择性。划痕试验表明,化合物53和化合物57也能够抑制
