Biochem/physiol Actions Bioactive terpenoid found in Ginkgo biloba. Bilobalide, a biologically active terpenic trilactone (terpinoid), derived from geranylgeranyl pyrophosphate (GGPP) is an inducer of cytochrome P450 enzymes CYP3A1 and CYP1A2. Bilobalide, a GABAA, GABAA-rho, 5-hydroxytryptamine type 3 (5-HT(3)) receptor antagonist, may be used to study the function of these receptors in brain processes such as cognition and memory. Bilobalide may also be used to study the function of platelet-activating factor receptors in cardiomyocytes.
