pro-inflammatory leukotrienes, is an attractive drug target for the pharmacotherapy of inflammatory and allergic diseases. Here, we present the design, synthesis and biological evaluation of novel series of ethyl 5-hydroxyindole-3-carboxylate derivatives that efficiently inhibit human 5-LO. SAR analysis revealed that the potency of compounds is closely related to the positioning of the substituents at the
5-脂氧合酶(5-LO)是一种催化促炎性白三烯生物合成初始步骤的酶,是炎性和过敏性疾病药物治疗的引人注目的药物靶标。在这里,我们目前的设计,合成和生物评估的新型系列5-羟吲哚-3-羧酸乙酯衍生物有效地抑制人5-LO。SAR分析表明,化合物的效力与取代基在苯硫基甲基环上的位置密切相关。在硫酚的邻位和邻位/对位中引入甲基或氯基团是最有利的修饰。在所有测试的化合物中,乙基5-羟基-2-(间苯二甲硫基甲基)-1-甲基-1H-吲哚-3-羧酸酯(19)是最有效的衍生物,在IC 50 = 0.7μM的无细胞测定中阻断5-LO活性,并在IC 50 = 0.23μM的多形核白细胞中抑制5-LO产物合成。
