通过2-氨基苯并噻唑与多种肉桂酸化合物的亲核酰基取代反应,通过简便、高效的方法合成了一系列苯并噻唑酰胺衍生物。所得产物表现出良好的热稳定性。使用市售标准药物酚磺乙胺作为阳性对照,评估所有化合物的体外止血活性。结果显示,化合物Q2具有显着的部分凝血活性,在5、10和50 μmol L -1时降低毛细血管通透性,激活凝血酶活性,并且比阳性对照组(酚磺乙胺,高达1283.9倍)具有更强的血小板聚集活性。在纳摩尔范围内)。分子模型研究表明,化合物Q2是一种竞争性凝血酶激活剂。因此, Q2可能是进一步生物筛选和药物分子生成的潜在先导。此外,本文还讨论了所制备化合物的结构-活性关系。

A novel series of potential biologically active new cinnamoyl amides were synthesized in good yield and short reaction times. We have studied the one-pot, solvent-free reaction of cinnamic acid derivatives with aromatic amines using 1,3-dicyclohexylcarbodiimide under microwave irradiation in the presence of small quantities of dimethylformamide to improve energy transfer.
