HDMP-28
HDMP-28 or methylnaphthidate is a piperidine based stimulant drug, closely related to methylphenidate, but with the benzene ring replaced by naphthalene. It is a potent dopamine reuptake inhibitor, with several times the potency of methylphenidate and a short duration of action, and is a structural isomer of another potent dopamine reuptake inhibitor, N,O-Dimethyl-4-piperidine-3-carboxylate.
Most of the TMP analogs of HDMP-28 have SERT Ki values in the range >10,000 and so are selective for dopamine and noradrenaline reuptake, with little or no effect on serotonin. HDMP-28 also has high affinity to SERT, and so behaves as a triple reuptake inhibitor.
D.R. = Discrimination Ratio = DA ÷ CFT.
A low D.R. = addictive, whereas a high D.R. = low propensity for self-administration.Legality
HDMP-28 is illegal in Switzerland as of December 2015.
