Benzothiophene derivatives like benzothiophene sulphonamides, biphenyls, or carboxyls have been synthesized and have found wide pharmacological usage. Here we report, bromo‐benzothiophene carboxamide derivatives as potent, slow tight binding inhibitors of Plasmodium enoyl‐acyl carrier protein (ACP) reductase (PfENR). 3‐Bromo‐N‐(4‐fluorobenzyl)‐benzo[b]thiophene‐2‐carboxamide (compound 6) is the most
苯并噻吩衍生物如苯并噻吩磺酰胺、联苯或羧基已被合成并具有广泛的药理学用途。在这里,我们报告了溴苯并噻吩甲酰胺衍生物作为疟原虫烯酰基-酰基载体蛋白 (ACP) 还原酶 (PfENR) 的有效、缓慢的紧密结合抑制剂。3-Bromo-N-(4-fluorobenzyl)-benzo[b]thiophene-2-carboxamide (compound 6) 是最有效的抑制剂,对纯化的 PfENR 的 IC50 为 115 nM。化合物 6 的抑制常数 (Ki) 对辅因子为 18 nM,对巴豆酰辅酶 A 为 91 nM。这些抑制剂显示出与辅因子的竞争动力学和与底物的非竞争动力学。因此,这些化合物有望用于开发有效的抗疟药。© 2011 IUBMB IUBMB Life, 63(12): 1101–1110, 2011
