Biosynthesis of defensive coccinellidae alkaloids: Incorporation of fatty acids in adaline, coccinelline, and harmonine

In this study, we report on in vitro incorporation experiments of several labelled fatty acids in the ladybird alkaloids coccinelline (Coccinella 7-punctata), adaline (Adalia 2-punctata), and harmonine (Harmonia axyridis). The obtained results clearly indicate that stearic acid is the precursor of coccinelline and harmonine, whereas myristic acid is at the origin of the carbon skeleton of adaline. Possible pathways for the biosynthesis of these alkaloids are presented. In vitro incorporation experiments of labelled fatty acids in the ladybird alkaloids coccinelline (Coccinella 7-punctata), adaline (Adalia 2-punctata) and harmonine (Harmonia axyridis) indicate that stearicacid is the best precursor for the biosynthesis of coccinelline and harmonine, whereas myristic acid is more efficient for the formation of the carbon skeleton of adaline.
