k-351

Nipradolol (KT-210; K-351), an alpha-1-adrenergic receptor antagonist, effectively inhibits the elevation of intraocular pressure (IOP) induced by Phenylephrine in an albino rabbit model, suppresses noradrenaline (NA)-induced muscle contractions, and demonstrates vasodilatory effects on the coronary artery in dogs [1] [2].

Methyldopa (MK-351), an alpha-adrenergic agonist (selective for α2-adrenergic receptors) psychoactive medicine, is served as an antihypertensive or sympatholytic.

Methyldopa hydrate (MK-351 hydrate) is a DOPA decarboxylase inhibitor and indirect α2-adrenergic receptor agonist used to treat hypertension. It inhibits the sympathetic nervous system, decreases production of dopamine, norepinephrine, and epinephrine, and exhibits NO-dependent sedative activity.

L-(-)-α-Methyldopa hydrochloride is an alpha-adrenergic agonist psychoactive drug. It is used as a sympatholytic or antihypertensive. Methyldopa has a dual mechanism of action. It is a competitive inhibitor of the enzyme DOPA decarboxylase, which converts
