合成了一系列[[((四唑-5-基芳基)氧基]甲基]苯乙酮,并作为白三烯D4诱导的豚鼠回肠收缩的拮抗剂进行了评估。在苯乙酮的3-位上用乙基(66),丙基(68),丁基(83)和异丁基(84)取代,得到的-log IC 50值分别为7.9、8.0、7.8和7.7。当四唑-5-基通过化学键(67),亚甲基(68)或乙烯(71)与对位的第二个苯环连接时,会得到同样有效的化合物。为了保持高拮抗剂活性,苯乙酮应在2位上被羟基取代,四唑环应具有酸性氢原子。1- [2-羟基-3-丙基-4-[[4-(1H-四唑-5-基甲基)苯氧基]甲基]苯基]乙酮(68,
This invention provides novel benzene derivatives which are leukotriene antagonists, formulations of those derivatives, intermediates for preparing the derivatives, and a method of using those derivatives for the treatment of conditions characterized by an excessive release of leukotrienes.
