Abstract/OtherAbstract:
Marasmin, which is especially known from the two South African species Tulbaghia alliacea and Tulbaghia violacea, but was also described for the garlic mushroom Marasmius alliaceus, is the precursor of the thiosulfinate marasmicin. Marasmicin has attracted considerable attention because of its antifungal and tuberculostatic activity. However, many Allium species of subgenus Melanocrommyum, especially Allium suworowii, are also very rich in marasmin. Allium suworowii revealed concentrations of marasmin up to 1.6%, related to the fresh weight of bulbs, whereas up to 3.0 %, related to air-dried fruiting bodies, of the corresponding γ-glutamyl-marsmin were found in Marasmius alliaceus. Both species show much higher amounts of marasmin as Tulbaghia and could be considered as natural source for isolation of this compound. Further promising Allium species with considerable amounts of marasmin besides other cysteine sulfoxides are Allium stipitatum and Allium altissimum. (RsRc)-Marasmin is typical for the investigated species of the subgenus Melanocrommyum, whereas the γ-glutamyl-(SSRC)-marasmin is the only cysteine sulfoxide for the genus Marasmius known until now. Both cysteine sulfoxides were isolated and described as o-phthaldialdehyde-(OPA)-derivatives.. Furthermore, the cysteine sulfoxides methiin, propiin, , eventually S-(2-pyrrolyl)-L-cysteine sulfoxide and the S-(2-pyridyl)-L-cysteine N-oxide were found.
