Biochem/physiol Actions
MK-0524 is a potent and selective prostaglandin D2 (PGD2) receptor PTGDR (DP1) antagonist with inverse agonist activity (Ki = 570 pM/DP1, 2.95 nM/TP, 745 nM/DP2, >890 nM for EP1/2/3/4, FP and IP). MK-0524 inhibits cAMP accumulation in PGD2-challenged human platelets (IC50 = 90 pM) and blocks PGD2-induced nasal congestion in a sheep allergic rhinitis model in vivo (by 99% at 0.1 mg/kg i.v.). MK-0524 decreases DP1-dependent basal cAMP level in HEK293 (1-100 nM) without affecting DP1-dependent basal ERK1/2 phosphorylation (up to 1 μM).
Potent and selective prostaglandin D2 (PGD2) receptor PTGDR (DP1) antagonist with inverse agonist activity in vitro and in vivo.
