Background: Bradykinin receptor B2 is a G protein-coupled receptor for bradykinin. Recent studies on mice myocardium revealed that the activation of the cardiac sympathetic system through the stimulation of cardiac sensory nerves involved the activation of the B2 receptor. B2 receptor agonists may have important clinical value in the treatment and prevention of various cardiovascular disorders such as hypertension, ischemic heart disease, left ventricular hypertrophy, ventricular remodeling and congestive heart failure, as well as diabetic disorders by mimicking the reported beneficial effects of bradykinin. Blocking bradykinin B2 receptors after experimental cerebral ischemia reduces brain edema, infarct volume and neuronal necrosis, and improves neurological outcome. Thus, B2 antagonists may be a promising new class of compounds for clinical use after the onset of cerebral ischemia.
