A 77636 hydrochloride is a selective and potent dopamine D1-like agonist stimulating the release of adenylate cyclase. It has been reported that upon binding to D1DR (dopamine D1 receptors), A 77636 hydrochloride displays 85% of the intrinsic activity that dopamine provides. Some studies show that A 77636 hydrochloride also increases the release of cortical acetylcholine. A 77636 hydrochloride is an activator of D1DR.
