A new series of C1-glycosyl thiazole derivatives was synthesised by the reaction of 1-(1,3,4,6-tetra-O-acetyl-2-deoxy-β-D-glucopyranos-2-yl)thiourea with 2-bromoacetophenone derivatives. Subsequent removal of the acetyl groups were conducted using NaOMe–MeOH. The structures of all new products were confirmed by IR, 1H NMR and HRMS (ESI). The acetylcholinesterase inhibitory activities of these new compounds
1-(1,3,4,6-四-O-乙酰基-2-脱氧-β-D-吡喃葡萄糖-2-基)硫脲与2-基反应合成了一系列新的C1-糖基噻唑衍生物。溴苯乙酮衍生物。随后使用 NaOMe-MeOH 进行乙酰基的去除。所有新产品的结构均通过 IR、1H NMR 和 HRMS (ESI) 确认。测试了这些新化合物的乙酰胆碱酯酶抑制活性。其中,N-(2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-β-D-glucopyranosyl)-4-(4-nitrophenyl)-1,3-thiazole-2-amine显示出最佳活性,抑制率为 43.21%。
