title: Phenopyrrozin, a new radical scavenger produced by Penicillium sp. FO-2047.
abstract: A new radical scavenger, named phenopyrrozin, was isolated from the culture broth of Penicillium sp. FO-2047. Phenopyrrozin was purified from whole broth solvent extraction, silica gel chromatography, and HPLC. The structure of phenopyrrozin was elucidated as 5,6,7,7a-tetrahydro-2-hydroxy-1-phenyl-3H-pyrrolizin-3-one. The IC50 of phenopyrrozin against lipid peroxidation induced by Cr2K2O7 was 73 micrograms/ml. Phenopyrrozin also reduced chromosomal aberrations induced by paraquat.
