this series which is exemplified by 1-[3-(naphth-2-ylmethoxy)phenyl]-1-(thiazol-2-yl)propy l methyl ether (2d, ICI211965). 2d inhibits cell-free guinea pig 5-LPO activity, LTC4 synthesis in plasma free mouse macrophages, and LTB4 synthesis in rat and human blood (IC50s 0.1 microM, 8 nM, 0.5 microM, and 0.4 microM, respectively) but does not inhibit the synthesis of cyclooxygenase products at concentrations
(甲氧基烷基)噻唑是新颖的5-脂氧合酶(5-LPO)抑制剂,既不是氧化还原剂也不是铁螯合剂。考虑到酶活性位点的假设模型导致了该系列,该系列以1- [3-(萘-2-基甲氧基)苯基] -1-(噻唑-2-基)丙基甲基醚(2d,ICI211965)为例)。2d抑制无细胞豚鼠5-LPO活性,无血浆小鼠巨噬细胞中的LTC4合成以及大鼠和人类血液中的LTB4合成(IC50分别为0.1 microM,8 nM,0.5 microM和0.4 microM),但不抑制在巨噬细胞中合成浓度高达50 microM,在血液中合成浓度高达100 microM的环氧合酶产物。2d在大鼠中具有口服活性(给药后1小时内在血液中离体ED50 10 mg / kg)。SAR研究表明,高体外效力需要甲氧基,噻唑基,和萘基,并且主要取决于取代方式。(甲氧基烷基)噻唑是手性的。1-甲氧基-6-(萘-2-基甲氧基)-1-(噻唑-2-基
