Deserpidine (S3562-GRP)

Deserpidine (Harmonyl), an alkaloid isolated from the root of Rauwolfia canescens related to Reserpine, is a competitive angiotensin converting enzyme (ACE) inhibitor. Deserpidine also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex. Deserpidine is used as an antihypertensive agent and a tranquilizer.
