Phenylpropylaminopentane
Phenylpropylaminopentane
Stimulant drug of the substituted phenethylamine class
(-)-1-Phenyl-2-propylaminopentane (also known as (-)-PPAP and N,α-dipropylphenethylamine)[1][2][3] is a stimulant of the substituted phenethylamine class that has been derived from selegiline.[4] When compared with selegiline and other substituted phenethylamines (-)-PPAP has a notably different mechanism of action and pharmacological effect.[4]
(-)-PPAP is classified as a monoaminergic activity enhancer that stimulates the impulse propagation mediated transmitter release of the neurotransmitters dopamine, norepinephrine and serotonin in the brain. Unlike stimulants such as amphetamine, which release a flood of monoamine neurotransmitters in an uncontrolled manner, (-)-PPAP instead only increases the amount of neurotransmitters that get released when a neuron is stimulated by receiving an impulse from a neighbouring neuron. Both amphetamine and (-)-PPAP promote the release of monoamines and deuteramines, however while amphetamine causes neurons to release neurotransmitter stores into the synapse regardless of external input, (-)-PPAP does not influence the pattern of neurotransmitter release and instead releases a larger amount of neurotransmitters than normal.[5]
(-)-PPAP has no monoamine oxidase inhibitory activity.[6]
