adenosine A2A receptors antagonist

MRS3558 is an agonist of A3 adenosine receptors.

CAY10680 is a dopamine-sparing, benzothiazinone compound that selectively inhibits both MAO-B activity (IC50 = 34.9 nM in human) and adenosine A2A receptors (Ki = 39.5 nM in human). It demonstrates significantly less potent inhibitory values for other adenosine receptor subtypes (Kis > 1 μM) and MAO-A (IC50 ≥ 10 μM). At 1-20 μM, CAY10680 has been shown to abolish cAMP accumulation in CHO cells transfected with adenosine A2A receptors. In the central nervous system adenosine A2A receptor expression is localized to dopamine-innervated areas where heteromeric complexes are formed with dopamine D2 receptors. Because inhibition of adenosine A2A receptors has been shown to enhance D2 receptor function, the blockade of adenosine A2A receptors has emerged as a potential treatment for Parkinson's disease. An additional strategy in the treatment of Parkinson's disease has been to block the activity of monoamine oxidase B (MAO-B), the enzyme involved in dopamine catabolism.

The A1, A2A, A2B, and A3 adenosine receptors (ARs) are ubiquitous G protein-coupled receptors. The four AR subtypes have been implicated in several areas of therapeutic interest such as stroke and other ischemic conditions, as well as inflammation, neurodegenerative diseases, diabetes, and sleep regulation. A3 AR antagonists are of interest as therapeutic agents in glaucoma agents and inflammation. CAY10498 is a potent and selective A3 AR antagonist exhibiting a Ki of 37 nM with 60 and 200-fold selectivity over A1 and A2A adenosine receptors, respectively. CAY10498 is also a structural analog of reversine, a dedifferentiation agent of embryonic progenitor cells. However, no dedifferentiation effects or any connection between A3 AR antagonism and dedifferentiation have been demonstrated.
