β-Cedrene ((+)-β-Cedrene), a sesquiterpene isolated from both Centaurea kotschyi var. kotschyi and Centaurea kotschyi var. decumbens, exhibits a broad range of biological activities, including antibacterial, anti-inflammatory, antispasmodic, tonic, diuretic, sedative, insecticidal, and antifungal properties. Additionally, β-Cedrene acts as a potent competitive inhibitor of the CYP2B6-mediated bupropion hydroxylase activity, demonstrating a K i value of 1.6 μM [1] [2].
