Abstract
- Virotoxins are a group of monocyclic peptides recently identified in the deadly mushroom Amanita virosa by Faulstich and coll. We found that two of these peptides, which have a methyl sulfonyl group, namely viroidin and viroisin are very effective to protect F-actin against oxidative degradation by osmium tetroxide in vitro. Their desoxo analogs, which have a methyl sulfoxyde group instead of methyl sulfonyl are less active, therefore there exists a relationship between the chemistry of the sulfur group and the activity of the peptides.
