α-Pinene is highly bioavailable with 60% human pulmonary uptake with rapid metabolism or redistribution. α-Pinene is an anti-inflammatory via PGE1, and is likely antimicrobial. It exhibits activity as an acetylcholinesterase inhibitor, aiding memory. Like borneol, verbenol and pinocarveol (−)-α-pinene is a positive modulator of GABAA receptors. It acts at the benzodiazepine binding site. α-Pinene forms the biosynthetic base for CB2 ligands, such as HU-308.
