The cruciferous phytoalexins brassinin and cyclobrassinin are intermediates in the biosynthesis of brassilexin

Following feeding experiments with the tetradeuterated cruciferous phytoalexins brassinin ( 5b) and cyclobrassinin ( 6b), leaves of Brassica carinata were elicited with the blackleg causing fungus Phoma lingam and incubated. Spectroscopic and HPLC analyses indicated that both brassinin ( 5a) and cyc...

Zusammenfassung:	Following feeding experiments with the tetradeuterated cruciferous phytoalexins brassinin ( 5b) and cyclobrassinin ( 6b), leaves of Brassica carinata were elicited with the blackleg causing fungus Phoma lingam and incubated. Spectroscopic and HPLC analyses indicated that both brassinin ( 5a) and cyclobrassinin ( 6a) were incorporated into the cruciferous phytoalexin brassilexin ( 7a).
