3-[6-(Acetylamino)-3-pyridinyl]-N-[2-[[2,4-dichloro-3-[[(2-methyl-8-quinolinyl)oxy]methyl]phenyl]methylamino]-2-oxoethyl]-(E)-2-propenamide, or FR 173657, is a nonpeptide bradyykinin B2 receptor antagonist. It is an orally-active noncompetitive antagonist with high affinity to the B2, that inhibits BK-induced bronchoconstriction and B2 receptor-mediated phosphatidylinositol hydrolysis
