2,4-Dihydroxy-9-phenyl-1H-phenalen-1-one (4-hydroxyanigorufone, 1), a compound isolated from Anigozanthos flavidus and Monochoria elata, displayed a high radical scavenging capacity in the ORAC assay. A systematic approach was adopted in order to explore

[phenyl-13C6]Lachnanthocarpone ([phenyl- 13C6]2,6-dihydroxy-9-phenylphenalen-1-one), a hypothetical intermediate in the biosynthesis of various natural phenylphenalenones, was prepared in four steps using [U- s
Variability of phenylpropanoid precursors in the biosynthesis of phenylphenalenones in Anigozanthos preissii

Feeding experiments using 13C labelled precursors and NMR spectroscopic studies revealed general biosynthetic incorporation of phenylalanine and variable incorporation of cinnamic acid, p-coumaric acid, caffeic acid and ferulic acid into phenylphenalenones in root cultures of Anigozanthos preissii. Evidence was obtained for parallel pathways of phenylphenalenone biosynthesis, with respect to the left phenylpropanoid unit, and a sequence involving utilisation of p-coumaric acid with late generation of an intermediate catechol moiety in the right phenylpropanoid unit.

, p. 974 - 980 (2007/10/03)
Several perinaphthenone/phenylphenalenone compounds were synthesized to establish a relationship between structure and antifungal activity against Mycosphaerella fijiensis. Substitutions on the unsaturated carbonyl system or addition of a phenyl group reduced antibiotic activity.
