Atopaxar (E5555) is a potent, orally active, selective and reversible thrombin receptor protease-activated receptor-1 (PAR-1) antagonist. Atopaxar, an antiplatelet agent, interferes with platelet signaling. Atopaxar can be used for the research of atherothrombotic disease[1][2].
Atopaxar (0.0001-10 μM; 1h) inhibits haTRAP (high-affinity thrombin receptor activating peptide) binding to PAR-1 on human platelet membranes in a concentration-dependent manner, with an IC50 of 0.019 μM[2].Atopaxar inhibits human platelet aggregation induced by thrombin or TRAP in a concentration-dependent manner[2].Atopaxar does not inhibit PRP (platelet-rich plasma) aggregation induced by ADP, U46619, collagen, and PAR-4ap, up to a concentration of 20 μM[2].
Atopaxar (30-100 mg/kg; p.o.) causes a dose-dependent prolongation of the time to occlusion of the femoral artery in photochemically-induced thrombosis (PIT) guinea pigs model[2]. Atopaxar does not prolong bleeding time in guinea pigs at the highest tested dosage of 1000 mg/kg[2].
