  • Title: Novel spironolactone-analogs as impurities in spironolactone.
    Author: Chen H, Wang XY, Yang ZD, Li YC.
    Journal: Steroids; 2004 Sep; 69(10):647-52. PubMed ID: 15465109.
    Abstract:
    Six novel spironolactone-analogs steroids (3-8) were isolated from spironolactone by using various chromatographic methods. Their structures were elucidated by spectrometric analysis. Two of the analogs (3 and 7) were confirmed by X-ray crystallography. The A-ring of compounds 3-7 is opened at C-2C-3 bond, and compound 7 is an organic polysulfide, which has a rare, nine-membered ring with a five sulfur atom bridge.
