Some newly discovered mycotoxins.
The discovery of the aflatoxins in 1960 has taken place in the present era of the intense awareness of the importance of environmental contaminants. It has dramatically influenced subsequent fungal research with the resulting rapid increase in the number of publications describing mycological, chemical, toxicological and epidemiological aspects of mycotoxins. In this contribution results will be discussed which were published only subsequent to 1970. In this period the importance of several new classes of mycotoxins was realized, e.g. the toxic cytochalasins and the tremorgens. The potential role of highly oxygenated metabolites in mycotoxicosis was emphasized by the establishment of secalonic acids A and D. emodin, moniliformin, altenuisiol alternariol and austdiol as toxins. The structure of viridicatumtoxin, C30H31NO11, a metabolite produced by Penicillium viridicatum will be described. It is a novel compound, structurally related to the tetracyclines. The characterization of several mycotoxins from other toxigenic fungi will be reported.
