especially good activity. Conformational restriction of either the polar region or lipid tail produced compounds devoid of activity. A number of selected analogues were also evaluated in vivo as antagonists of LTD4-induced bronchoconstriction in the guinea pig. The data established these compounds as a novel class of leukotriene antagonists with potential utility for the treatment of asthma and other immediate
已经制备了一系列5-炔基-和5-芳基-4,6-二硫代癸二酸和相关化合物以评估白三烯拮抗剂活性。炔基化合物是通过相应的炔属缩醛通过硫缩醛交换制备的。芳基衍生物是由适当的苯甲醛合成的,其中大多数是通过以下三种通用途径之一制备的:迈耶的恶唑啉法,钯偶联法和羟基苯甲醛烷基化。在体外检查了这些类似物拮抗LTD4诱导的豚鼠气管平滑肌收缩的能力,并与[3H] LTD4竞争豚鼠肺膜上的受体位点。这项研究发现了许多构效关系。脂质尾部和极性区域中的两个亚甲基的最佳链长为10-12个原子(或其等价物)。在芳族系列中,邻位和间位取代的化合物具有可比的活性,而对位衍生物则无活性。芳香环和脂质尾部的取代通常具有良好的耐受性,末端苯基(6)和乙炔(33)类似物的活性特别好。极性区或脂质尾部的构象限制产生了缺乏活性的化合物。在体内也评估了许多选择的类似物作为豚鼠中LTD4诱导的支气管收缩的拮抗剂。数据确定这些化合物为一类
