What is SC-51322?

Description

The prostaglandin E₂ (PGE₂) receptor (EP₁) is involved in triggering PGE₂-mediated pain as well as neuronal survival and growth. SC-51322 is a selective EP₁ antagonist that inhibits PGE₂ signaling in a guinea pig ileum muscle strip assay with a pA₂ value of 8.1 and demonstrates analgesic activity in a mouse writhing assay with an ED₅₀ value of 0.9 mg/kg. It is pharmacologically similar to SC-51089, but does not release hydrazine, a known carcinogen to rats, as does SC-51089. SC-51322 potentiates the vasorelaxation of human pulmonary vein induced by PGE₂ with an EC₅₀ value of 7.75 μM.
