The pyrrolidino enaminones, with the carboxylic acid chain fixed at the nitrogen, inhibit cyclooxygenase more potently or selectively than 5‐lipoxygenase. According to the structure‐activity relationships discussed the potency depends significantly on the chain length of the carboxylic acid, the substitution pattern of the heterocyclic moiety and of the phenyl group. Compound 4c is the most efficient
羧酸链固定在氮原子上的吡咯烷烯胺酮比 5-脂氧合酶更有效或选择性地抑制环加氧酶。根据所讨论的结构-活性关系,效力显着取决于羧酸的链长、杂环部分和苯基的取代模式。化合物4c是最有效的环氧合酶抑制剂。对于结合特征,比较了花生四烯酸的未折叠构象和氟比洛芬、双氯芬酸、ML 3000 和先导化合物 4a 的能量最小化构象。除了已知的结构特征外,还假设羧酸官能团和苯基残基的距离相似,可以解释与酶活性位点的相互作用。
