Bradykinin receptor B2 is a constitutively expressed G protein-coupled receptor. In canines, recent studies revealed that the canine heart can be preconditioned by an abdominal surgical incision to mediate a protective effect through the activation of the B2 receptor. In the presence of the B2 antagonist HOE140, the protective effect was not observed. Thus, B2 antagonists may be a promising new class of compounds to treat ischemic heart disease or for clinical use after the onset of cerebral ischemia.
