azolidin-3-yl]-4-biphenylcarboxamide derivatives was synthesized and evaluated for analgesic and anti-inflammatoryactivity. In this study, biphenyl-4-carboxylic acid hydrazide was converted to the corresponding aryl hydrazones using aryl aldehydes in the presence of catalytic amount of glacial aceticacid. The aryl hydrazones on reaction with thioglycolic acid in the presence of anhydrous zinc chloride
合成了一系列新颖的N- [5-(亚芳基)-2-(芳基)-4-氧代-噻唑烷-3-基] -4-联苯羧酰胺衍生物,并评估了其镇痛和抗炎活性。在这项研究中,在催化量的冰醋酸存在下,使用芳基醛将联苯-4-羧酸酰肼转化为相应的芳基hydr。在无水氯化锌存在下与巯基乙酸反应的芳基腙,得到Ñ-[2-(芳基)-4-氧代-噻唑烷-3-基] -4-联苯甲酰胺在无水乙酸钠和冰醋酸的存在下与芳族醛进一步反应,得到标题化合物。所有化合物在10 mg / kg的剂量下均表现出抗炎活性。所有这些新合成的化合物的结构均通过其元素分析(C,H,N)和光谱数据(IR和1 H NMR)确定。
