Hippuristanol

Hippuristanol is a small molecule found in the coral Isis hippuris[1] which was discovered by Jerry Pelletier and others of McGill University in Montreal, Quebec, Canada.[2] It appears to have anti-viral activity and may hold promise as a cancer therapy.[3] Binds to and inhibits the eukaryotic translation initiation factor protein eIF4A.[4]
