4-(Nitrophenyl)hydrazone derivatives of N-acylhydrazone were synthesized and screened for suppress lymphocyte proliferation and nitrite inhibition in macrophages. Compared to an unsubstituted N-acylhydrazone, active compounds were identified within initial series when hydroxyl, chloride and nitro substituents were employed. Structure-activity relationship was further developed by varying the position
合成了N-酰基hydr的4-(硝基苯基)hydr衍生物,并筛选了其在巨噬细胞中抑制淋巴细胞增殖和抑制亚硝酸盐的作用。与未取代的N-酰基hydr相比,当使用羟基,氯和硝基取代基时,在初始系列中鉴定出了活性化合物。通过改变这些取代基的位置以及连接与结构相关的取代基,进一步发展了结构-活性关系。取代基位置的变化揭示了更有希望的复合抗炎药系列。相反,N附加到4-(硝基苯基)hydr部分的-甲基基团降低了活性。通过调节巨噬细胞中IL-1β的分泌和前列腺素E2的合成以及抑制淋巴细胞中钙调磷酸酶磷酸酶的活性,可以实现化合物的抗炎活性。化合物SintMed65进入小鼠腹膜炎的急性模型,口服后抑制了中性粒细胞的浸润。总而言之,我们详细地证明了N-N-酰基new新家族的结构要求和抗炎活性的潜在机制,这可能代表了抗炎药物开发的重要医学化学方向。
