Phenopyrrozin, a new radical scavenger produced by Penicillium sp. FO-2047
1995
A new radical scavenger, named phenopyrrozin, was isolated from the culture broth of Penidllium sp. FO-2047. Phenopyrrozin was purified from whole broth by solvent extraction, silica gel chromatography, and HPLC. The structure of phenopyrrozin was elucidated as 5, 6, 7, 7a-tetrahydro2-hydroxy-l-phenyl-3H-pyrrolizin-3-one. The IC50 of phenopyrrozin against lipid peroxidation induced by Cr2K2O7 was 73μg/ml. Phenopyrrozin also reduced chromosomal aberrations induced by paraquat.
