Terpinolene

Terpinolene is a monoterpene found in the essential oils of various plants, including C. sativa, and has diverse biological activities including antiproliferative and antioxidant properties. It inhibits expression of AKT1 in Jurkat and K562 cells by 95% when used at a concentration of 0.05% and inhibits the growth of K562 cells when used at a concentration of 0.01%. Terpinolene also inhibits the growth of HT-29, Hep-2, NCI-292, and HL-60 cells (IC50s = 16.7, 13.7, 17.4, and 28.8 μg/ml, respectively). In cultured human blood cells, terpinolene (10-75 mg/L) increases total antioxidant capacity (TAC), but decreases cell viability when used at a concentration of ≥150 mg/L.
