α-Pyrrolidinopentiophenone (also known as α-pyrrolidinovalerophenone, α-PVP, O-2387, β-keto-prolintane, prolintanone, or desmethylpyrovalerone) is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug. Colloquially, it is sometimes called flakka or gravel. α-PVP is chemically related to pyrovalerone and is the ketone analog of prolintane.
