  摘要：

  腺苷已被建议在哮喘患者中诱导支气管高反应性，据信这是A（2B）腺苷受体（AdoR）介导的途径。我们假设选择性的高亲和力A（2B）AdoR拮抗剂可能在哮喘的治疗中提供治疗益处。为了确定一种高亲和力，选择性的A（2B）AdoR拮抗剂，我们合成了8-（C-4-吡唑基）黄嘌呤。化合物22 8-（1H-吡唑-4-基）-1,3-二丙基黄嘌呤是N-1未取代的吡唑衍生物，对A（2B）具有良好的结合亲和力（K（i）= 9 nM） AdoR，但与A（1）AdoR相比只有2倍的选择性。在N-1-吡唑的22位引入苄基导致19，其具有中等选择性。SAR研究的最初重点是制备19的取代苄基衍生物，因为相对于19，相应的苯基，苯乙基和苯丙基衍生物显示出A（2B）AdoR亲和力和选择性降低。苯环上的首选取代如在33和36中分别在19中，C 1包含一个吸电子基团，特别是F或CF（3），在保持对A（2B）AdoR的亲和力的同时

• Analogs of caffeine and theophylline: effect of structural alterations on affinity at adenosine receptors

  A variety of analogues of caffeine and theophylline in which the 1-,3-, and 7-methyl substituents have been replaced with n-propyl, allyl, propargyl, and isobutyl and, in a few cases, with chloroethyl, hydroxyethyl, or benzyl were assessed for potency and selectivity as antagonists at A1- and A2-adenosine receptors in brain tissue. Caffeine and theophylline are nonselective for these receptors. Nearly all of the 22 analogues of caffeine are more potent than caffeine itself at adenosine receptors. Replacement of the 1-methyl moiety with n-propyl, allyl, or propargyl substituent has little effect on potency at the A1 receptor while enhancing potency about 7- to 10-fold at the A2 receptor. 3,7-Di-methyl-1-propylxanthine is only slightly (1.4-fold) more potent than caffeine at the A1 receptor while being 10-fold more potent at the A2 receptor. 1,3-Di-n-propyl-7-methylxanthine is also selective for the A2 receptor, being 8-fold more potent than caffeine at the A1 receptor and 40-fold more potent at the A2 receptor. A number of other caffeine analogues including 3,7-dimethyl-1-n-propylxanthine, 7-allyl-1,3-dimethylxanthine, and 1,3-dimethyl-7-propargylxanthine are also somewhat selective for the A2 receptor. The most potent caffeine analogue was 1,3-di-n-propyl-7-propargylxanthine, which was about 100-fold more potent than caffeine at both A1 and A2 receptors. The 10 theophylline analogues were relatively nonselective except for the 1-ethyl analogue and the 1,3-diallyl analogue, which were selective for the A2 receptor, and the 1,3-di-n-propyl, 1,3-diisobutyl, and 1,3-dibenzyl analogues, which were somewhat selective for the A1 receptor. 1,3-Di-n-propylxanthine was 20-fold more potent than theophylline at the A1 receptor and 5-fold more potent at the A2 receptor.
