L-765,314 is a drug which acts as a potent and selective antagonist of the α1-adrenergic receptor subtype α1B.[1] It has mainly been used to investigate the role of α1B-adrenergic receptors in the regulation of blood pressure.[2][3] The α1B receptor is also thought to have an important role in the brain; however, L-765,314 does not cross the blood–brain barrier.[4]
