Pentedrone (also known as α-methylamino-valerophenone) is a stimulant of the cathinone class that has been sold as a designer drug and has been found since 2010 as an ingredient in a number of " bath salt" mixes sold as legal highs.      
Pentedrone acts as a
norepinephrine-dopamine reuptake inhibitor without causing their release, the same mechanism of action as methylphenidate. 
Pentedrone has been linked to at least one death where it was combined with
α-PVP and caused heart failure.
A forensic standard of Pentedrone is available, and the compound has been posted on the Forendex website of potential drugs of abuse.
On January 28, 2014, the DEA listed it, along with 9 other synthetic cathinones, on the Schedule 1 with a temporary ban, effective February 27, 2014.
Pentedrone is a
Anlage II controlled drug in Germany.
As of October 2015 Pentedrone is a controlled substance in China.
Pentedrone is banned in the Czech Republic.
