A metabolite of Captopril. A new antihypertensive agent | [Definition]
ChEBI: An organic disulfide in which the disulfide bond links two units of captopril. It is a secondary metabolite of captopril. | [Description]
Captopril disulfide is a metabolite and symmetrical disulfide form of the angiotensin converting enzyme (ACE) inhibitor captopril . Captopril disulfide is the main degradation product of captopril and is formed by oxidation. It is a potential impurity in commercial preparations of captopril. Captopril disulfide inhibits angiotensin I-induced increases in mean arterial pressure in anesthetized dogs (ID50 = 0.231 mg/kg, i.v.). | [References]
