WIN 64338 hydrochloride is a potent and competitive antagonist of bradykinin B2 receptor . Bradykinin B2 receptor is a G-protein coupled receptor for bradykinin. Bradykinin is an inflammatory nonapeptide and plays a critical role in edema, vasodilation, pain fiber stimulation and smooth muscle spasm. WIN 64338 hydrochloride is a potent and competitive bradykinin B2 receptor antagonist. In human IMR-90 cells, WIN 64338 inhibited bradykinin binding to the bradykinin B2 receptor with Ki value of 64 nM and inhibited Ca2+ efflux stimulated by bradykinin with pA2 value of 7.1 in a competitive way. WIN 64338 inhibited guinea pig ileum contractility induced by bradykinin with pA2 value of 8.2 and also inhibited acetyicholine-induced contractility . In iris sphincter isolated from rabbit, WIN 64338 (1-10 μM) inhibited contractile responses evoked by bradykinin with pKB value of 6.6 . In guinea-pig tracheal smooth muscle cells, WIN 64338 inhibited inositol phosphate formation induced by bradykinin . In guinea-pigs, WIN 64338 (30 nM) significantly inhibited the increases in plasma extravasation induced by bradykinin via the release of tachykinins from the trigeminal nerve .
