About: N,α-Diethylphenethylamine

N,α-Diethylphenethylamine (N,α-DEPEA, 2-ethylamino-1-phenylbutane, EAPB) is a close chemical analog of methamphetamine, which has been sold as a designer drug. It was originally patented by Knoll Pharma as one of several analogs for pharmaceutical applications. In animals models these analogs showed properties of cognitive enhancement and increased pain tolerance. Nevertheless, this class of compounds was never developed into a medicine.N,α-DEPEA has not been studied in humans, but experts such as Pieter Cohen of Harvard Medical School expect it to be less potent than methamphetamine, but greater than ephedrine.
