Yeah, but doesn't appear to be overly popular hah.
Methcathinone -> α-Methylamino-Propiophenone, MAPP
Buphedrone -> α-Methylamino-Butyrophenone, MABP
Pentedrone -> α-Methylamino-Valerophenone, MAVP
Hexedrone -> α-Methylamino-Caprophenone, MACP
Pentedrone (same length as α-PVP) appears to be the most potent. A longer chain will lead to less potent compounds, as seen with α-PHP (PV-7) and Hexedrone, PV-8, PV-9 and so on.
