st 1059

Description

ST 1059: metabolite of midodrine (ST-1085); RN given refers to parent cpd [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

deglymidodrine : An aromatic ether that is 1,4-dimethoxybenzene which is substituted at position 2 by a 2-amino-1-hydroxyethyl group. The immediate and active metabolite of midrodine, it is a direct-acting sympathomimetic with selective alpha-adrenergic agonist activity. Midrodine is used (generally as its hydrochloride salt) as a prodrug for deglymidodrine, which acts as a peripheral vasoconstrictor in the treatment of certain hypotensive states.

Roles (3)

RoleDescription
alpha-adrenergic agonistAn agent that selectively binds to and activates alpha-adrenergic receptors.
sympathomimetic agentA drug that mimics the effects of stimulating postganglionic adrenergic sympathetic nerves. Included in this class are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters.
vasoconstrictor agentDrug used to cause constriction of the blood vessels.
