The metabolic pathway of the dopaminagonistic ergoline derivative, proterguride, was studied in vitro in a rat liver perfusion experiment. Metabolites were isolated by preparative HPLC and identified by MS and NMR analyses. In total, seven compounds could be identified. The metabolic steps involved in the biodegradation of proterguride are N-deethylation, N-oxidation, hydroxylation, and/or dehydrogenation and oxidative cleavage of the indole ring.

D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction

D001711 Biotransformation The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
