Pharmacology

Trideca-7,9,11-trienoic acid has been shown to have an antianxiety effect in Mus musculus, Rattus norvegicus, and Homo sapiens. It reduces hypolocomotion caused by anxiety, which was psychopharmacologically induced with mCPP, in Mus musculus and Rattus norvegicus. A 2 mg/kg dose of diazepam has a very similar effect to 20 mg/kg of trideca-7,9,11-trienoic acid. This may suggest that trideca-7,9,11-trienoic acid is also a GABA agonist like diazepam.^[1][4][5][6]

Extraction from A. cynapium

Trideca-7,9,11-trienoic acid can be extracted from dried aerial parts of A. cynapium with methanol, followed by chloroform, followed by column chromatography with DCM and methanol (40:60), followed by flash chromatography with DCM and methanol (92.5:7.5), followed by preparative TLC.^[1]

Uses

In addition to its potential as an anxiolytic, trideca-7,9,11-trienoic acid has also been studied for use in inks and protective coatings.^[1][7]
