4-Methoxycinnamic acid - An unusual phenylpropanoid involved in phenylphenalenone biosynthesis in Anigozanthos preissii

Abstract In vitro root cultures of Anigozanthos preissii and Wachendorfia thyrsiflora (Haemodoraceae) are suitable biological systems for studying the biosynthesis of phenylphenalenones. Here we report how we used these root cultures to investigate precur

O-Methylation of phenylphenalenone phytoalexins in Musa acuminata and Wachendorfia thyrsiflora

Biosynthetic O-methylation at various sites along the backbone of inducible phenylphenalenones in Musa acuminata var. Williams (Musaceae) and Wachendorfia thyrsiflora (Haemodoraceae) was investigated using 13C-labelled precursors. The inducibility of O-methylated metabolites was demonstrated in both species and the origin of methoxyl group from [methyl-13C]l-methionine was confirmed. In addition to known phenylphenalenones, a methoxylated metabolite, 4-(4-hydroxy-3-methoxy-phenyl)-benzo[de]isochromene-1,3-dione, was detected and its structure elucidated mainly by NMR spectroscopic techniques. The experiments were used to discriminate methionine-derived and artificial methoxy groups formed during methanolic extraction. Finally, demethylation of 4′-methoxycinnamic acid and subsequent conversion to 3′,4′-methylenedioxycinnamic acid was demonstrated in M. acuminata.
