RWJ-58259
RWJ-58259 is a selective PAR-1 inhibitor with an IC50 value of 0.15 μM. RWJ-58259 binds selectively to PAR-1, blocks the binding of tethered ligands, interferes with calcium mobilization and PAR-1-related cellular functions, and exhibits no PAR-1 agonist activity or thrombin proteolytic inhibitory activity. RWJ-58259 inhibits thrombin-induced platelet aggregation, calcium signaling and vascular smooth muscle cell proliferation, reduces neointimal thickness and arterial stenosis, and alleviates vascular occlusion and platelet deposition. RWJ-58259 can be used in the research of thrombotic diseases and vascular injury associated with acute coronary intervention.
