Ginkgolide A (BN-52020) is a highly active PAF antagonist cage molecule that is isolated from the leaves of the Ginkgo biloba tree. Shows potential in a wide variety of inflammatory and immunological disorders. Ginkgolide A (BN-52020) failed to affect apoptotic damage neither in serum-deprived nor in staurosporine-treated neurons.
Ginkgolide A significantly shortened the sleeping time in anesthetized mice.
