Description and Uses
(–)-β-Pinene is a bicyclic monoterpene that has been found in various plants, including C. sativa, with diverse biological activities. It is lethal to S. littoralis third instar larvae (LD50 = 65 μg/larva). (–)-β-Pinene inhibits infectious bronchitis virus (IBV) replication (IC50 = 1.32 mM) and exhibits a cytotoxic concentration (CC50) value of greater than 10 mM in Vero cells. In vivo, (–)-β-pinene (100 mg/kg) decreases immobility time in the forced swim test in mice, an effect that can be reversed by the serotonin (5-HT) receptor subtype 5-HT1A antagonist WAY-100635 .
(-)-β-Pinene has been used as a standard for the analysis of terpenoid compounds in plant essential oils by GC analysis. It may be used as a building block to synthesize natural products such as grandisol, robustadial and (+)-nopinone. (-)-β-Pinene undergoes hydroformylation in the presence of platinum/tin catalysts to form trans-10-formylpinane.
