MCE 國際站:PSB 0777 ammonium hydrate
產品活性:PSB 0777 ammonium hydrate 是一種有效的選擇性腺苷 A2A 受體激動劑,對大鼠和人 A2A 受體的 Ki 值分別為 44.4 nM,360 nM。PSB 0777 ammonium hydrate 對大鼠和人的 A1 受體的 Ki 值分別 ≥10000 nM,541 nM。PSB 0777 ammonium hydrate 顯示出較差的大腦滲透性和口服生物利用度。PSB 0777 ammonium hydrate 具有用于炎性腸病 (IBS) 研究的潛力。
研究領域:GPCR/G Protein
作用靶點:Adenosine Receptor
In Vitro: 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.
PSB-0777 ammonium binds human β1 (Ki=4.4 μM) and β3 (Ki=3.3 μM) adrenergic receptors.
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.
In Vivo: PSB 0777 ammonium hydrate (0.4 mg/kg/day; oral gavage; from the day 5 to 10) causes a marked reduction of inflammatory cell infiltration and an amelioration of colonic mucosal architecture.
PSB 0777 ammonium hydrate (0.03, 0.3, 3 mg/kg; i.p.) causes dose-dependent hypothermia and hypoactivity in C57BL/6J mice.
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.
