The aldehyde derivatives of 1,3-dipropyl xanthines as described in this paper, constitutes a new series of selective adenosine ligands displaying bronchospasmolytic activity. The effect of substitution at 3rd - and 4th -position of 8-phenyl xanthine has also been taken into consideration. The synthesized compounds showed varying binding affinities at different adenosine receptor subtypes (A1 , A2A
如本文所述,1,3-二丙基黄嘌呤的醛衍生物构成了一系列新的选择性腺苷配体,显示出支气管痉挛活性。还考虑了 8-苯基黄嘌呤的第 3 位和第 4 位取代的影响。合成的化合物在不同的腺苷受体亚型(A1、A2A、A2B 和 A3)上显示出不同的结合亲和力,并且对组胺气溶胶诱发的豚鼠哮喘具有良好的体内支气管痉挛活性。大多数化合物对 A2A 受体亚型显示出最大的亲和力。发现具有二乙基部分的单取代 3-氨基烷氧基 8-苯基黄嘌呤(化合物 12e)是最有效的 A2A 腺苷受体配体(Ki = 0.036 µM),其次是二取代的 4-氨基烷氧基-3-甲氧基-8-苯基黄嘌呤(Ki = 0.
