Abstract
1-Piperideine, 5-aminopentanoic acid, and its lactam, 2-piperidone, were identified as metabolites of cadaverine in 10,000 g mouse liver supernatants to which diamine oxidase had been added. Both metabolites were also found when the cadaverine metabolite 1-piperideine was incubated with the preparation which suggested that 1-piperideine is an intermediate in the formation of 5-aminopentanoic acid and 2-piperidone. Identification of the metabolites was based on gas chromatography-mass spectrometric analysis in comparison to authentic standards. Mouse brain homogenates converted 1-piperideine to 5-aminopentanoic acid. The results suggest that the metabolic fate of cadaverine may provide precursors of pharmacologically active analogues of GABA.
