5-Lipoxygenase (5-LO) and microsomal prostaglandin E2 synthase (mPGES)-1 are key enzymes in the biosynthesis of leukotrienes and prostaglandin (PG)E2, respectively, and are considered as valuable targets for the treatment of inflammatory diseases. Here, we present the identification of 2-mercaptohexanoic acid derivatives as dual inhibitors of 5-LO and mPGES-1. The lead compound 2(4-(3-biphenyloxyp
5-脂氧合酶(5-LO)和微粒体前列腺素E 2合酶(mPGES)-1是白三烯和前列腺素(PG)E 2生物合成中的关键酶,被认为是治疗炎性疾病的重要靶标。在这里,我们介绍2-巯基己酸衍生物作为5-LO和mPGES-1的双重抑制剂的鉴定。铅化合物2(4-(3-(3-联苯氧基丙氧基)苯硫基)己酸(21)在无细胞试验中抑制人5-LO和mPGES-1的IC 50分别 为3.5和2.2μM,并抑制5-LO在完整细胞中具有更高的效力(IC 50 = 0.9μM)。化合物21(10μM)既不显着抑制相关的12-或15-LO,也不抑制环氧合酶-1和-2或胞质磷脂酶A 2。基于对5-LO和mPGES-1的选择性和有效抑制,有必要进一步评估炎症的临床前模型中的这些2-巯基己酸。
