RTI-171
-2β--3β-tropane is a phenyltropane derivative which acts as a selective dopamine reuptake inhibitor, with a relatively slow onset of action and short duration of effects found in animal studies....

RTI-121
-2β-Carboisopropoxy-3β-tropane is a stimulant drug used in scientific research, which was developed in the early 1990s. RTI-121 is a phenyltropane based, highly selective dopamine reuptake inhibitor and is derived from methylecgonidine...
