The ginkgolides represent a challenge for the organic chemist owing to thei
r unique cage structure and their high potential biological activity. They
were found to be potential PAF antagonists. The results of studies carried
out in our laboratory are discussed, leading to conclusions on ginkgolides
quantitative structure-activity relationship by using CoMFA and the probabl
e pharmacophore and the interaction fashion between ginkgolides and PAF rec
eptor.
