Identification of zinc and cadmium complexes of the mycotoxin sporidesmin A by electrospray mass spectrometry
Abstract
The fungal toxin sporidesmin A (spdA), responsible for the occurrence of facial eczema in livestock, forms a dianionic thiolato complex of the type [(spdA)2M]2– with zinc and cadmium, identified by electrospray mass spectrometry; such complexes may be important in the protection against facial eczema offered by zinc salts.
