Fosgonimeton is an investigational new drug that is being evaluated to treat neurodegenerative diseases such as Alzheimer's and Parkinson's disease.^[1] It is a pro-drug of the active metabolite dihexa. Dihexa in turn binds to the hepatocyte growth factor (HGF) and potentiates its activity at its receptor, c-Met.^[2]^[3]
