α-Pyrro​lidino​pentio​thiophenone (also known as α-PVT) is a synthetic stimulant of the cathinone class that has been sold online as a designer drug.[1][2][3] It is an analogue of α-PVP where the phenyl ring has been replaced by thiophene.

α-PVT was first identified in Japan in 2013.[4] Its metabolism has been described in literature.[5][6]

Side effects

α-PVT has been shown to possess high cytotoxicity against human cell lines.[7]


Sweden's public health agency suggested classifying α-PVT as hazardous substance on November 10, 2014.[8]

As of October 2015 α-PVT is a controlled substance in China.[9]

α-PVT is illegal in Switzerland as of December 2015.[10]
