Altertoxins and the related compound stemphyltoxin-III, also produced by Alternaria, are mutagenic. Tenuazonic acid (Chemical name: 2H-Pyrrol-2-one, 3-acetyl-1,5-dihydro-4-hydroxy-5- (1-methylpropyl)-, (S- (R*,R*))-) appears to inhibit protein synthesis by preventing newly formed protein molecules from detaching from the ribosomes on which they formed.
