Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/26604665

The sesquiterpene trilactone bilobalide is one of the active constituents of the 50:1 Ginkgo biloba leaf extract widely used to enhance memory and learning. Bilobalide was found to antagonise the direct action of gamma-aminobutyric acid (GABA) on recombinant alpha(1)beta(2)gamma(2L) GABA(A) receptors. Bilobalide showed anticonvulsant properties through the activation of glutamic acid decarboxylase (GAD) enzyme, which is a key enzyme in biosynthesis of GABA. Bilobalide has been proposed to exert protective and trophic effects on neurons. Bilobalide may be useful in developing therapy for diseases involving age-associated neurodegeneration. Bilobalide is an active component of EGb, a standardised extract of Ginkgo biloba leaves. Bilobalide accounts for about 3% of the total extract.

Curator's Comment: Also was used subcutaneously. In focal cerebral ischemia models, the administration of bilobalide (5-20 mg/kg, s. c.) 60 min before ischemia dose-dependently reduced the infarct area in mouse brain and the infarct volume in rat brain 2 days after the onset of the injury. https://www.ncbi.nlm.nih.gov/pubmed/13130383
Oral administration of bilobalide at 3 and 6 mg/kg/day
Route of Administration: Oral
Bilobalide at 3, 10 and 30 uM increased GABA EC50 values: 1.5 times (56.0 –82.0 uM), 1.8 times (54.1 – 95.9 uM) and 2.7 times (67.7 –182.0 uM), respectively in in Xenopus laevis oocytes
