Smilagenin

DB05450InvestigationalSmall molecule

Smilagenin is a novel non-peptide, orally bioavailable neurotrophic factor inducer that readily reverses free radical neurotoxicity produced by 1-ethyl-4- phenylpyridium (MPP+) in dopaminergic neurones and reverses the decrease of neuronal... Pre-clinical work with smilagenin showed it to be neuroprotective against betya-amyloid and glutamate damage which contributes to Alzheimer's disease and reverses the changes in the area of the brain involved in Parkinson’s disease.
