P4pal10 is a pepducin antagonist of proteinase-activated receptor 4 (PAR4) and formyl peptide receptor 2 (FPR2), as well as an agonist of free fatty acid receptor 2 (FFAR2/GPR43).1,2 It is composed of a peptide that corresponds to the third intracellular loop of human PAR4 that is conjugated to palmitic acid .1 P4pal10 selectively inhibits the aggregation of isolated human platelets induced by the PAR4 peptide agonist AYPGKF-NH2 over the PAR1 peptide agonist SFLLRN-NH2 , the TP receptor agonist U-46619 , the platelet glycoprotein Ib (GPIb), GPIX, and GPV agonist ristocetin, ADP , or collagen at 5 µM. It inhibits increases in intracellular calcium induced by the FPR1 and FPR2 agonist WKYMVm but not by the FPR1 agonist fMLF in isolated human neutrophils and induces superoxide production in TNF-α primed isolated human neutrophils stimulated with the FFAR2 allosteric modulator Cmp58.2 P4pal10 (1, 3, or 10 µg/kg) reduces myocardial infarct size in a rat model of coronary artery ligation-induced ischemia-reperfusion injury.3 It increases the paw withdrawal threshold in rat models of osteoarthritis induced by monoiodoacetate injection into the knee joint or medial meniscal transection.4

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
