Chemistry:MDPHP
MDPHP (3',4'-Methylenedioxy-α-pyrrolidinohexiophenone) is a stimulant of the cathinone class originally developed in the 1960s,[1] which has been reported as a novel designer drug. In the UK its slang name is monkey dust.[2][3] It is closely related to the potent stimulant MDPV though with slightly milder effects, and has been used as an alternative in some countries following the banning of MDPV.[4][5][6][7]
Pharmacology
MDPHP acts as a potent norepinephrine-dopamine reuptake inhibitor. The IC50 values for MDPHP are 60-935 nM at NET, 8.4-50 nM at DAT and 9000 nM at SERT.[8][9]
Legal status
MDPHP is specifically listed as a controlled substance in Japan [10] and Hungary,[11] and is controlled under analogue provisions in a number of other jurisdictions.
Documented fatalities
A case of a "fatal acute intoxication caused by MDPHP" in a 48 year old male was reported in February 2022 by physicians at an Italian hospital.[12] Another case has been reported, involving a 30-years-old male cocaine consumer, found dead on July 20th, 2023, in Florence, Italy.[13]
