Enzo Life Sciences R(-)-Deprenyl. HCl (100mg). CAS: 14611-52-0
Deprenyl inhibits apoptosis and displays neuroprotective effects in a variety of in vitro and in vivo systems. In vivo it rescues nigral dopaminergic neurons after systemic MPTP treatment. In vitro it rescues PC12 cells from apoptotic cell death induced by trophic withdrawal. The putative target responsible for the anti-apoptotic effects is glyceraldehyde-3-phosphate dehydrogenase. Deprenyl also inhibits monoamine oxidase-B, which is not involved in its anti-apoptotic mechanism. Parkinson’s disease therapeutic. Alternative name: Selegiline hydrochloride. Purity: ≥98% (HPLC). Solubility: Soluble in water. Long Term Storage: Ambient.
