1-Benzyl-4-(3-phenylpropyl)-1,2,3,6-tetrahydropyridine is a synthetic organic compound used primarily as a research intermediate in medicinal chemistry and neuropharmacology. It serves as a scaffold for designing novel central nervous system (CNS) agents due to its tetrahydropyridine core, which is structurally related to known neurotoxins like MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine). This similarity makes it valuable in studies exploring mechanisms of neurodegeneration, such as in Parkinson's disease models, where analogs are investigated for their effects on dopaminergic neurons and monoamine oxidase (MAO) pathways, including potential interactions with MAO-B. It is also employed in synthetic routes to develop selective MAO inhibitors or dopaminergic modulators for research into cognitive, mood, and neurodegenerative disorders. Strictly for laboratory use; not intended for therapeutic or human applications.
