3',4'-Methylenedioxy-α-pyrrolidinobutiophenone

3',4'-Methylenedioxy-α-pyrrolidinobutyrophenone (MDPBP) is a stimulant of the cathinone class developed in the 1960s, which has been reported as a novel designer drug. MDPBP is sometimes sold under the name "NRG-1" as a mixture with other cathinone derivatives, including flephedrone, pentylone, MαPPP and its higher homologue MDPV. As with other cathinones, MDPBP has been shown to have reinforcing effects in rats.
