Sinalbins A and B, phytoalexins from Sinapis alba: elicitation, isolation, and synthesis.
The chemical structure and synthesis of sinalbin A is described. This cruciferous phytoalexin is produced by white mustard (Sinapis alba) after treatment with biotic and abiotic elicitors. In addition, a related metabolite, named sinalbin B, is present in extracts from elicited plants, but not in those from non-elicited controls. Sinalbin B, which was also synthesized, appears to be both a phytoalexin and a biosynthetic precursor of sinalbin A.
