series of 3-(4-hydroxy-1-naphthalenyl)-2-propenoic acids was prepared and the inhibitory activities of its members on IL-1 generation were evaluated both by in vitro systems using human monocytes and/or rat exudated macrophages stimulated with LPS, and by an in vivo system using the rat CMC-LPS air-pouch model. Many compounds in this series were found to be potent inhibitors of IL-1 generation both in
制备了一系列新的3-(4-羟基-1-萘基)-2-丙酸,并通过体外系统使用人单核细胞和/或大鼠渗出的巨噬细胞评估了其成员对IL-1生成的抑制活性。使用大鼠CMC-LPS气袋模型通过LPS刺激,并通过体内系统刺激。发现该系列中的许多化合物在体外和体内都是有效的IL-1生成抑制剂。构效关系表明,在大鼠CMC-LPS气袋模型中,通过口服给药在萘环上具有3-烷氧基,5-烷基和4-羟基取代基的(Z)-2-取代的丙酸表现出最佳的抑制作用。在所评估的化合物中,(Z)-3-(5-乙基-4-羟基-3-甲氧基-1-萘基)-2-甲基-2-丙烯酸(20a),对大鼠渗出的巨噬细胞抑制人单核细胞产生IL-1的作用(IC50值为3.0 microM,IC50值为1.4 microM)在口服CMC-LPS模型中显示出最有效的抑制活性。化合物20a还在炎症动物模型中显示出抗炎作用。
