A series of new thiophene derivatives has been synthesized using the Gewald protocol. The acetylcholinesterase inhibition activity was assayed according to Ellman’s method using donepezil as reference. Some of the compounds were found to be more potent inhibitors than the reference. 2-(2-(4-(4-Methoxyphenyl)piperazin-1-yl)acetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (IIId) showed 60% inhibition, compared to only 40% inhibition by donepezil.
一系列新的噻吩衍生物通过Gewald方法合成。根据Ellman的方法测定了这些化合物对乙酰胆碱酯酶的抑制活性,并以多奈哌齐作为对照。发现其中一些化合物的抑制效果比对照组更强。2-(2-(4-(4-甲氧基苯基)哌嗪-1-基)乙酰氨基)-4,5,6,7-四氢苯并[b]噻吩-3-羧酰胺(IIId)显示出60%的抑制,而多奈哌齐仅显示40%的抑制效果。
