Juvabione is the methyl ester of todomatuic acid, both of which are sesquiterpenes (C15) found in the wood of true firs of the genus Abies. They exist as part of a mixture of sesquiterpenes based on the bisabolane scaffold. Sesquiterpenes of this family,
(±)9-HpODE is a racemic mixture of the fatty acid hydroperoxide product (9(S)-HpODE) formed from lipoxygenase action on linoleic acid. It shows antimicrobial activity against various fungal and bacterial pathogens and thus may play a role in plant defense. In mammalian species, monocyte-induced oxidization of LDL generates significant amounts of esterified 9-HpODE, which is rapidly reduced to 9-HODE.
Lumisterol (9β,10α-Ergosterol), a steroid compound, is the (9β,10α)-stereoisomer of Ergosterol. Lumisterol is a photoprotective agent against UVB-induced DNA damage and anti-proliferative activities[1].
