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