title: Formation of 18-deoxy-19-noraldosterone by a human aldosterone-producing adenoma.
abstract: The recently synthesized 18-deoxy-19-noraldosterone is a potent aldosterone antagonist. In the present study we demonstrate the in vitro formation of 18-deoxy-19-noraldosterone from 19-noraldosterone in a human aldosterone-producing adenoma and normal adrenal tissue. The metabolite was isopolar, cochromatographed with the authentic standard on high-performance liquid chromatography, and the identity was further analyzed by mass spectrometry. The possible role of 18-deoxy-19-noraldosterone in primary aldosteronism is also discussed.
