WIN 64338 hydrochloride is a potent, selective, nonpeptide competitive antagonist of bradykinin B2 receptor. WIN 64338 hydrochloride inhibits [3H]-Bradykinin binding to the bradykinin B2 receptor on human IMR-90 cells with a Ki of 64 nM. WIN 64338 hydrochloride also can inhibits [3H]Quinuclidinyl benzilate binding to the rat brain muscarinic receptor (Ki=350 nM)[1][2].
