Impairments of glycogen and drug metabolisms by chloropeptide, a hepatotoxic mycotoxin of Penicillium islandicum sopp.

Administration of chloropeptide, a hepatotoxic cyclic pentapeptide of Penicillium islandicum Sopp, caused a marked decline in the hepatic glycogen synthetase activity with concomitant increase in NADP-dependent G-6-P dehydrogenase activity. The microsomalmixed function oxygenases were also reduced in the liver of rats following chloropeptide treatment.
