(D)-Deprenyl

Compound Code KAT-NEU-09
Pharmacological Tag MAO-B Inhibitor / Dopaminergic Modulator / Neuroenergetic Probe
Structural Class Propargylated Phenylethylamine
Mechanism (Putative) Irreversible inhibition of MAO-B → ↑ Dopamine in striatum ↓ H2O2 production → Neuroprotection (oxidative hypothesis) Propargyl moiety → Mitochondrial anti-apoptotic signaling Metabolized to D-amphetamine → Central stimulation
Functional Role Cognitive preservation in Parkinson's Delay of L-DOPA dependence Stimulant adjunct in depressive states Mitochondrial resilience enhancer Experimental anti-aging vector
Structural Analogues Rasagiline Desmethylselegiline (L)-Deprenyl Methamphetamine Pargyline
Predicted Onset Slow (irreversible enzyme binding requires cumulative dosing)
Predicted Duration Long (>24h due to MAO-B regeneration kinetics)
Affinity Profile MAO-B: high (irreversible covalent binding) DAT/NET/SERT: Robust (via metabolites) Mitochondrial apoptotic cascade: indirect interference Sigma receptors: speculative binding
Computational Predictions CNS Activity: high BBB Penetration: confirmed Neuroplasticity: potential via BDNF upregulation Mitochondrial Bioenergetics: preserved under stress Risk of Stimulation: high (via amphetamine metabolites) Neurotoxicity: Neglectible Longevity Pathways: candidate for caloric-mimetic synergy
Interpretation An amphetamine in disguise — dressed in neuroprotective garb. (D)-Deprenyl occupies a unique biochemical duality: stimulant & safeguard. While pharmacologically "clean", its metabolic afterlife is dirtied by amphetamine. Used in Parkinson's but peeking into anti-aging labs. It doesn’t merely delay death — it modulates hypothamalic neuronal-aging center. Perfect neuropharmacologically.
