used in silico screening to rapidly direct the synthesis, based on the copper-catalyzed 3 + 2 Huisgen's reaction (click chemistry), of potential inhibitors. We designed 26 new triazole-based compounds in accordance with the pocket binding requirements of human mPGES-1. Docking results, in agreement with ligand efficiency values, suggested the synthesis of 15 compounds that at least in theory were shown
微粒体前列腺素E 2合酶(mPGES)-1催化PGH 2向PGE 2的转化它涉及多种病理,例如发烧,疼痛和炎症性疾病。为了鉴定新型的mPGES-1抑制剂,我们在计算机筛选中基于铜催化的3 + 2 Huisgen反应(点击化学反应),使用了潜在的抑制剂,以快速指导合成。我们根据人mPGES-1的口袋结合要求设计了26种新的基于三唑的化合物。对接结果与配体效率值一致,表明合成了15种化合物,至少从理论上讲,它们在抑制mPGES-1方面更有效。这些选定化合物的生物学评估已揭示了三种新的潜在抗炎药:(I)化合物4对mPGES-1具有选择性,IC 50值为3.2μM,(II)化合物双重抑制5-脂氧合酶和mPGES-1的化合物20,和(III)化合物7显然起5-脂氧合酶激活蛋白抑制剂的作用(IC 50 = 0.4μM)。
