    Product Description

    AAT-008 is an orally bioavailable and potent antagonist of the prostaglandin E2 (PGE2) receptor subtype 4 (EP4; IC50 = 16.3 nM in a human EP4 functional assay).1 It is selective for EP4 with IC50 values of 2.4, 1,890, >20,000, and >20,000 nM for binding to human recombinant EP4, EP2, EP1, and EP3, respectively. AAT-008 has potent binding affinity for human, rat, and dog EP4 (Kis = 0.97, 6.1, and 38 nM, respectively) and suppresses PGE2-induced elevation of intracellular cAMP with an antagonistic potency (pA2) of 1.1 nM in vitro. Oral administration of AAT-008 reduces carrageenan-induced mechanical hyperalgesia in rats in a dose-dependent manner.

    WARNING This product is not for human or veterinary use.
