3’4′-Methylenedioxy-α-pyrrolidinobutyrophenone (MDPBP) is a stimulant compound developed in the 1960s which has been reported as a novel designer drug often sold under the name NRG-1 as a mixture with other substituted cathinone derivatives including flephedrone pentylone MαPPP and MDPV.The main metabolic steps are thought to be demethylenation followed by methylation of one hydroxy group aromatic and side chain hydroxylation oxidation of the pyrrolidine ring to the corresponding lactam as well as ring opening to the corresponding carboxylic acid.
