4F-MPH: Difference between revisions

Line 20:

4F-MPH is thought to act primarily as a [[dopamine and norepinephrine]] [[reuptake inhibitor]], meaning it effectively boosts the levels of dopamine and norepinephrine [[neurotransmitters]] in the brain by binding to and partially blocking the transporter proteins that normally clear these catecholamines from the synaptic cleft. This allows dopamine and norepinephrine to accumulate within the reward pathways in the brain, resulting in stimulating and euphoric effects.

According to a ~~recent study~~, 4-FMPH is ~~about as~~ effective ~~as methylphenidate as a~~ norepinephrine reuptake ~~inhibitor~~ (~~NRI~~), ~~but~~ is ~~approximately three~~ times as effective at ~~inhibiting the~~ reuptake of ~~dopamine as its parent compound~~.~~{{citation needed}}~~

According to a pharmacological evaluation, the ''(±)-threo'' isomer of 4-FMPH is 2.15 times more effective at dopamine reuptake inhibition, and 2.7 times more at norepinephrine reuptake inhibition, than its parent compound methylphenidate. The ''(±)-erythro'' isomer, however, is 65 times less effective at dopamine reuptake inhibition and 45.6 times less effective at norepinephrine reuptake inhibition than methylphenidate. Neither racemate of 4-MPH has a significant impact on serotonin reuptake.<ref>Analytical characterization and pharmacological evaluation of the new psychoactive substance 4-fluoromethylphenidate (4F-MPH) and differentiation between the (±)-threo and (±)-erythro diastereomers | https://analyticalsciencejournals.onlinelibrary.wiley.com/doi/abs/10.1002/dta.2167</ref>
