Parmodulin 2 (ML161) is an allosteric inhibitor of protease-activated receptor 1 (PAR1) with an IC50 of 0.26 μM[1]. Parmodulin 2 is a potent and non-competitive inhibitor of SFLLRN-induced P-selectin expression leading to inhibition of platelet aggregation in vitro and platelet thrombus formation in vivo[2].
Parmodulin 2 (ML161; 10 µM; for 30 minutes) inhibits proinflammatory signaling in endothelial HUVECs cells[3].
Parmodulin 2 (ML161; 5 mg/kg; IV) significantly inhibits platelet thrombus formation, with a 73% inhibition in AUC (area under the curve)[2].
Parmodulin 2 inhibits platelet thrombus formation in vivo, and it does not prolong bleeding time. Parmodulin 2 selectively inhibits platelet aggregation through Par1 and the α2A-adrenergic receptor[2].
