Discovery of New Ginsenol-Like Compounds with High Antiviral Activity.

A number of framework amides with a ginsenol backbone have been synthesized using the Ritter reaction. We named the acetamide as Ginsamide. A method was developed for the synthesis of the corresponding amine and thioacetamide.

Synthesis and structure-activity relationships of novel camphecene analogues as anti-influenza agents.

A chemical library was constructed based on the scaffold of camphecene (2-(E)-((1R,4R)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene-aminoethanol).
