Chemistry:3-Chlorophenmetrazine

From HandWiki

3-Chlorophenmetrazine (3-CPM; code name PAL-594) is a recreational designer drug with stimulant effects.[1][2] It is a substituted phenylmorpholine derivative, closely related to better known drugs such as phenmetrazine and 3-fluorophenmetrazine (3-FPM; PAL-593).[1][2]

The drug has been shown to act as a norepinephrine–dopamine releasing agent (NDRA) with additional weak serotonin release.[1][2] Its EC50 values for induction of monoamine release are 27 nM for dopamine, 75 nM for norepinephrine, and 301 nM for serotonin in rat brain synaptosomes.[1][2] Hence, it releases dopamine about 3-fold more potently than norepinephrine and about 11-fold more potently than serotonin.[1][2]

Similarly to cis-4-methylaminorex, the drug is notable in being one of the most selective dopamine releasing agents (DRAs) known, although it still has substantial capacity to release norepinephrine.[1][2]
