A new series of C2-glycosyl benzofuranylthiazole derivatives was synthesised by the further cyclization of glycosyl thiourea and 2-(bromoacetyl)-benzofuran via Hantzsch’s method. The corresponding 2-(bromoacetyl)-benzofuran derivatives were obtained by the reaction from various salicylaldehydes, and the glycosyl thiourea was prepared through a series of steps from D-Glucosamine. The acetylcholinesterase-inhibitory
通过Hantzsch法进一步环化糖基硫脲和2-(溴乙酰基)-苯并呋喃,合成了一系列新的C2-糖基苯并呋喃基噻唑衍生物。由各种水杨醛反应得到相应的2-(溴乙酰基)-苯并呋喃衍生物,由D-氨基葡萄糖通过一系列步骤制备糖基硫脲。产品的乙酰胆碱酯酶抑制活性通过 Ellman 方法测试。随后评估了最具活性的化合物的 50% 抑制浓度值。N-(1,3,4,6-四-O-苄基-2-脱氧-β-D-吡喃葡萄糖基)-4-(5-甲氧基-苯并呋喃-2-基)-1,3-噻唑-2-胺具有最佳的乙酰胆碱酯酶抑制活性,50% 抑制浓度为 2.03 ± 0.26 μM。
