N-Methyldopamine hydrochloride is a precursor of adrenaline in the adrenal medulla. N-Methyldopamine hydrochloride is a modification of the dopamine (DA), and retains agonist activity at the DA1 receptor. N-Methyldopamine hydrochloride remains capable of universal surface coating and secondary reactions using the surface catechols. N-Methyldopamine hydrochloride can be used for heart failure research[2].In Vitro: N-Methyldopamine hydrochloride shows highly improved surface coating properties, and exhibits an accelerated coating rate. N-Methyldopamine hydrochloride coating makes solid surface cell adhesion possible, and postfunctionalization of the coating is also possible.
