Phenylpropylaminopentane

Common card · No. 478516

1-Phenyl-2-propylaminopentane (PPAP), also known as α,N-dipropylphenethylamine (DPPEA) and by the developmental code name MK-306, is an experimental drug related to selegiline which acts as a catecholaminergic activity enhancer (CAE). PPAP is a CAE and enhances the nerve impulse propagation-mediated release of norepinephrine and dopamine. It produces psychostimulant-like effects in animals. In 2025, it was discovered that PPAP is a potent catecholamine reuptake inhibitor, including of dopamine and to a lesser extent of norepinephrine. The drug is a phenethylamine and amphetamine derivative and was derived via structural modification of selegiline. PPAP was first described in the literature in 1988 and in the first major paper in 1992. It led to the development of the improved monoaminergic activity enhancer (MAE) benzofuranylpropylaminopentane (BPAP) in 1999. PPAP was a reference compound for studying the MAE system for many years. However, it was superseded by BPAP, which is more potent...
