IC₅₀ & Target^[1]

PAR4

2 nM (IC₅₀)

All Protease Activated Receptor (PAR) Isoforms :

In Vitro

PAR4 antagonist 9 (Compound 32) exhibits favorable metabolic stability, with a remaining ratio of 85% in the human-derived system and 100% in the rat-derived system in metabolic stability tests^[1].
PAR4 antagonist 9 exhibits potent PAR4 antagonistic activity, with an FLIPR IC₅₀ of 2 nM and a γ-Thr PRP IC₅₀ of 4 nM^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

PAR4 antagonist 9 (Compound 32) (3 mg/kg; p.o.; single dose) produces complete, concentration-dependent inhibition of PAR4-mediated platelet aggregation for at least 7 h in cynomolgus monkeys, with effects reversing as plasma concentrations fall below 10 nM^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Cynomolgus monkeys (2 animals, healthy)^[1]
Dosage:

3 mg/kg
Administration:

p.o.; single dose
Result:

Achieved complete suppression of PAR4 agonist peptide-stimulated platelet aggregation at 3 h and 7 h post-dosing.
Attained plasma levels of 78.63 nM (monkey 1) and 77.87 nM (monkey 2) at 3 h, followed by concentrations of 49.44 nM (monkey 1) and 59.11 nM (monkey 2) at 7 h.
Lost sustained antithrombotic activity at 30 h post-dosing as efficacy returned to baseline, with plasma concentrations declining to 6.65 nM (monkey 1) and 1.04 nM (monkey 2).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
