Bopindolol-d9 (()-Bopindolol-d9) is the deuterium labeled Bopindolol (HY-B1562). Bopindolol (()-Bopindolol) is an orally active antagonist of beta-adrenoceptors (ARs) with partial agonist activity. Bopindolol is non-selective for beta1- and beta2-ARs and has low affinity for beta3-AR subtype. Bopindolol has intrinsic sympathomimetic as well as membrane stabilizing actions, inhibits renin secretion, and interacts with 5-HT receptors. Bopindolol is a proagent of Pindolol (HY-B0982). Bopindolol can be used for essential and renovascular hypertension research.
