Description
Ginkgolide C is a bioactive diterpenoid trilactone compound derived from the leaves of the Ginkgo biloba tree. Similar to its counterparts Ginkgolide A and Ginkgolide B, it is characterized by its unique trilactone structure with multiple chiral centers, contributing to its diverse pharmacological properties. Ginkgolide C is known for its potent antagonistic effects on platelet-activating factor (PAF), making it a promising candidate for treating inflammatory and allergic conditions. Additionally, it has been studied for its neuroprotective effects, particularly in the context of neurodegenerative diseases and cerebral ischemia.
