Abstract

Adenosine receptors have been the target of intense research with respect to potential use of selective ligands in a variety of therapeutic areas. Caffeine and theophylline are adenosine receptor antagonists, and over the past three decades a wide range of selective agonists and antagonists for adenosine receptor subtypes have been developed. A complication to the therapeutic use of adenosine receptor ligands is the observation that the effects of acute administration of a particular ligand can be diametrically opposite to the chronic effects of the same ligand. This 'effect inversion' is discussed here by Ken Jacobson and colleagues, and has been observed for effects on cognitive processes, seizures and ischaemic damage.

摘要

腺苷受体一直是深入研究的对象,涉及在各种治疗领域中潜在使用选择性配体。咖啡因和茶碱是腺苷受体拮抗剂,在过去三十年里,已开发出多种针对腺苷受体亚型的选择性激动剂和拮抗剂。腺苷受体配体治疗应用中的一个复杂情况是,观察到特定配体急性给药的效果可能与同一配体的慢性效果截然相反。肯·雅各布森及其同事在此讨论了这种“效应反转”,并且在对认知过程、癫痫发作和缺血性损伤的影响方面已观察到这种现象。
