2,5-Diaryl tetrahydrofurans, 2,5-diaryl tetrahydrothiophenes, 2,4-diaryl tetrahydrofurans, 2,4-diaryl tetrahydrothiophenes, 1,3-diaryl cyclopentanes, 2,4-diaryl pyrrolidines, and 2,5-diaryl pyrrolidines are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response. The compounds exhibit this biological activity by acting as PAF receptor antagonists, by inhibiting the enzyme 5-lipoxygenase, or by exhibiting dual activity, i. e., by acting as both a PAF receptor antagonist and inhibitor of 5-lipoxygenase.
A method to treat disorders mediated by PAF or leukotrienes is also disclosed, that includes administering an effective amount of one or more of the above-identified compounds or a pharmaceutically acceptable salt thereof, optionally in a pharmaceutically acceptable carrier.
本文披露了以下化合物:2,5-二芳基四氢呋喃,2,5-二芳基四氢噻吩,2,4-二芳基四氢呋喃,2,4-二芳基四氢噻吩,1,3-二芳基环戊烷,2,4-二芳基吡咯烷和2,5-二芳基吡咯烷,这些化合物可以减少多形核白细胞在炎症或免疫反应中的趋化和呼吸爆发,从而减少有害氧自由基的形成。这些化合物通过作为PAF受体拮抗剂、抑制5-脂氧合酶酶或表现出双重活性即同时作为PAF受体拮抗剂和5-脂氧合酶抑制剂来表现出这种生物活性。本文还披露了一种治疗PAF或白三烯介导的疾病的方法,包括在药学上可接受的载体中投与上述化合物或其药学上可接受的盐的有效量。
