L-765,314 is a drug which acts as a potent and selective antagonist for the Alpha-1 adrenergic receptor subtype α_1B. It has mainly been used to investigate the role of α_1B receptors in the regulation of blood pressure. The α_1B receptor is also thought to have an important role in the brain; however, L-765,314 does not cross the blood–brain barrier.
