(–)-2β-Carbophenoxy-3β-(p-
tolyl)tropane (RTI-4229-120) is a
phenyltropane derivative which acts as a reasonably selective
dopamine reuptake inhibitor, along with weaker inhibition of
noradrenaline and
serotonin reuptake.[1] It has a reasonably fast rate of occupancy of dopamine transporters in the brain, though slower than that of
cocaine itself.[2] RTI-120 has a short duration of action, along with other p-methyl substituted phenyltropanes such as
RTI-150,
RTI-171 and
RTI-199, giving it a more similar pharmacological profile to cocaine compared to longer acting analogues like
RTI-121 and
RTI-177.[3]
