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 growth factors and dopamine receptors in the brain. P58 is a protein synthesis stimulant acts by restoring levels of proteins that are altered in the ageing brain, reversing the loss of nerve receptors in the ageing brain and potentially allowing for the regrowth of neural connections. P58 therefore provides a totally novel mode of action with potential importance for diseases associated with ageing of the brain. P58 is one of a family of phytochemicals isolated from traditional treatments for the elderly that have previously been shown to offer significant benefit in the treatment of senile dementia.
