1-(2-Naphthyl)-2-propylaminopentane (NPAP), also known as 2-naphthyl-α,N-dipropylphenethylamine, is a monoaminergic activity enhancer (MAE) of the α-propylphenethylamine and naphthylaminopropane families related to phenylpropylaminopentane (PPAP).
[1] MAEs are agents that enhance the action potential-mediated release of monoamine neurotransmitters.
[2][3][4] NPAP is a MAE of norepinephrine and dopamine but not of serotonin.
[1] Like PPAP, it is inactive as a classical monoamine releasing agent.
[1] NPAP was developed by József Knoll and colleagues and was first described in 2001.
