Several esters of beta-carboline-3-carboxylic acid were synthesized and tested in respect to their affinity for the benzodiazepine receptor in bovine cortex membranes. Out of these derivatives, the methyl, ethyl, and n-propyl ester were clearly the most potent, while the n-butyl, benzyl, and 3-pyridylmethyl ester were considerably less active. Moreover, several beta-carboline-3-carboxylates with ethanol
合成了几种β-咔啉-3-羧酸酯,并测试了它们对牛皮质膜中苯并二氮杂receptor受体的亲和力。在这些衍生物中,甲基,乙基和正丙基酯显然是最有效的,而正丁基,苄基和3-吡啶基甲基酯的活性明显较低。此外,几种以乙醇衍生物为酯醇组分的β-咔啉-3-羧酸酯都比乙基或正丙基酯本身的活性差。结论是,β-咔啉-3-羧酸盐对苯并二氮杂receptor受体的亲和力极大地取决于分子大小以及酯醇组分的疏水性和电子参数。
