Metabolism of idebenone (CV-2619), a new cerebral metabolism improving agent: isolation and identification of metabolites in the rat and dog. 1985

T Kobayashi, and K Yoshida, and M Mitani, and H Torii, and S Tanayama

Metabolic studies of idebenone (CV-2619), a new cerebral metabolism improving agent, in the rat and dog by thin-layer chromatography, gas-liquid chromatography-mass spectrometry and fast atom bombardment-mass spectrometry led to characterization of the following metabolites: the parent compound, 6-(9-carboxynonyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (QS-10), 6-(7-carboxyheptyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (QS-8), 6-(5-carboxypentyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (QS-6), 6-(3-carboxypropyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (QS-4), 1- or 4-phenyl sulfate of the hydroquinone derivatives of CV-2619 and QS-4, and 1- and 4-phenyl glucuronides of the hydroquinone derivative of QS-10. These results indicated that CV-2619 was metabolized by oxidation of the side chain followed by beta-oxidation to form successively QS-10, QS-8, QS-6 and QS-4, and reduction of the quinone ring and subsequent conjugation yielding the sulfates and glucuronides of the hydroquinone derivatives of CV-2619, QS-10, QS-8, QS-6 and QS-4.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
