SAR247799 (S1P1 agonist 3) is an orally-active, selective G-protein-biased agonist for the sphingosine-1 phosphate receptor-1 (S1P1). It demonstrates EC50 values ranging from 12.6 to 493 nM in S1P1-overexpressing cells and HUVECs. SAR247799 holds promise as a valuable tool for investigating endothelial protection, particularly in the context of type-2 diabetes and metabolic syndrome[4].

S1PR1:12.6-493 nM (EC50)

SAR247799 (0, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, 10 μM; 10 min) induces a concentration-dependent phosphorylation of extracellular-regulated kinase-1/2 (Erk1/2) and protein kinase B (Akt) in HUVECs[1]. SAR247799 (0-10 μM, 8 min) induces impedance change in HUVECs in a dose-dependent manner[1]. SAR247799 (1 μM, 1st) does not cause desensitization demonstrated by Ca 2+ flux assay in S1P1-Chinese hamster ovary (CHO) cells[1].

SAR247799 (1 and 3 mg/kg; p.o.; 1 h before renal occlusion) dose dependently reduces the severity of ischemia/reperfusion (I/R)–induced acute kidney injury[1]. SAR247799 (0.3, 1, 3 mg/kg; i.v.) dose dependently increases the coronary conductance ratio in pig model of coronary endothelial dysfunction[1]. SAR247799 (30-min intravenous administration; 8- to 10-week-old farm pig) exposure (C max and AUC) increases with dose in pigs.

C max , maximum concentration. T max , time at which maximum concentration achieved. T last , last time point sampled. AUC 0-last , area under curve from 0 to last time point. Cl, clearance. Vss, volume at steady state or volume of distribution. T 1/2z , elimination half-life. N, number of animals. Animal Model: Acute kidney injury rats (12 to 15-week-old Fischer rats)[1]Dosage: 1 and 3 mg/kg Administration: P.o.; administered 1 hour before renal occlusion. Result: Inhibited the increase in serum creatinine (89 and 96% at 1 and 3 mg/kg) and urea (61 and 85% at 1 and 3 mg/kg). Protected renal proximal tubules against necrosis and blunted the development of interstitial hemorrhage. Animal Model: Acute kidney injury rats (8- to 12-week-old Fischer rats)[1]Dosage: 3 mg/kg Administration: P.o.; twice a day for 7 days and twice a day for 7 day Result: Showed a dosedependent trend for reducing macrophage.
