PSB 0777 ammonium hydrate
Based on 1 Customer Validation
PSB 0777 ammonium hydrate is a potent and selective adenosine A2A receptor full agonist with Ki values of 44.4 nM, 360 nM for rat and human A2A receptors, respectively. PSB 0777 ammonium hydrate has Ki values of ≥10000 nM, 541 nM for rat and human A1 receptors, respectively. PSB 0777 ammonium hydrate shows poor brain penetrant and perorally non-absorbable effect. PSB 0777 ammonium hydrate has the potential for inflammatory bowel disease (IBS) research research.

Biological Activity
Ki: 44.4 nM (rat A2A), 360 nM (human A2A), ≥10000 nM (rat A1) and 541 nM (human A1)[1]
PSB 0777 ammonium hydrate (compound 7) shows high selectivity for the A2AAR (>225-fold) versus the other AR subtypes (Ki values of >10000 nM and ≫10000 for human A2B receptor and A3 receptor, respectively). PSB 0777 ammonium hydrate acts as an full agonist at A2AAR with an EC50 value of 117 nM in CHO-K1 cells[1].
PSB-0777 ammonium binds human β1 (Ki=4.4 μM) and β3 (Ki=3.3 μM) adrenergic receptors[2].
PSB 0777 ammonium hydrate (0.1 µM, 1 µM, 10 µM) increases concentration-dependently Acetylcholine (Ach, 1 mM) contractions in untreated and inflamed rat ileum/jejunum preparations in ex vivo experiments[1].

PSB 0777 ammonium hydrate (0.03, 0.3, 3 mg/kg; i.p.) causes dose-dependent hypothermia and hypoactivity in C57BL/6J mice[2].
PSB 0777 ammonium hydrate cannot be absorbed systemically by the digestive mucosa once administered by the oral route. PSB 0777 ammonium hydrate (0.4 mg/kg/day; PO) has very low plasma concentrations in rats at 30 min (below 5 nM), and there is no plasma concentrations at 60 min after administration. PSB 0777 ammonium hydrate (0.4 mg/kg/day; IP) makes plasma concentrations well evident at 30 min, and decreases after 60 min, and is not detectable at 120 and 240 min[3].
