human a2a receptors

GS-6201 (CVT-6883) is a selective antagonist of the adenosine A2B receptor, demonstrating high affinity and selectivity with a Ki of 22 nM for human adenosine A2B receptors.

N6-Cyclopentyladenosine (CPA) is a selective agonist of the adenosine A1 receptor, mimicking its action with Ki values of 2.3 nM, 790 nM, and 43 nM for human A1, A2A, and A3 receptors, respectively. CPA is used to modulate cellular signaling, neurotransmission, and other biological processes.

Sch412348 is a potent competitive the human adenosine A2A receptor antagonist with Ki of 0.6 nM and has >1000-fold selectivity over all other adenosine receptors.

CGS 15943 is an orally bioavailable non-xanthine antagonist of the Adenosine Receptor. In transfected CHO cells, its Ki values for human A1, A2A, A2B, and A3 Adenosine Receptors are 3.5, 4.2, 16, and 50 nM, respectively.

MRS 1523 can exert an antihyperalgesic effect through N-type Ca channel block and action potential inhibition in isolated rat dorsal root ganglion (DRG) neurons. MRS 1523 is an effective and selective adenosine A3 receptor antagonist Ki: 18.9 nM and 113 n

MRS-1706 has Ki values of 1.39, 112, 157, and 230 nM for human A2B, A2A, A1, and A3 receptors respectively. MRS-1706 is an effective and selective adenosine A2B receptor inverse agonist.

SCH442416 (SCH 442416) is an selective antagonist of adenosine A2A receptor. SCH442416 binds to human and rat A2A receptors with high affinity (Ki values are 0.048 and 0.5 nM respectively).

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.

PSB 0777 ammonium hydrate is a potent and selective adenosine A2A receptor full agonist, with K i values of 44.4 nM for rat A2A receptors and 360 nM for human A2A receptors. For rat and human A1 receptors, it has significantly lower affinity, with K i values of ≥10000 nM and 541 nM, respectively. The compound exhibits poor brain penetration and is not orally absorbable. It is of interest in research related to inflammatory bowel disease (IBD) [1] [2] [3].
