number of novel xanthines bearing a variety of substituents at positions 1, 3, 7 and 8 were prepared and evaluated for their binding affinity to the human adenosine receptor A1, A2A, A2B and A3 subtypes. Several of the 1,3,8- and 1,3,7,8-substituted xanthines showed moderate-to-high affinity at human A2B and A1 receptors, with the most active compound (14q) having a pKi of 7.57 nM for hA2B receptors and
制备了许多在1、3、7和8位带有各种取代基的新颖黄嘌呤,并评估了它们与人腺苷受体A 1,A 2A,A 2B和A 3亚型的结合亲和力。1,3,8-和1,3,7,8-取代的黄嘌呤中的几种对人A 2B和A 1受体表现出中等至高亲和力,其中活性最高的化合物(14q)的ap K i为7.57。 n M对h A 2B受体的选择性和对h A 2A受体的选择性是8.1倍和h A 1的 受体的3.7倍。
