RTI-126, ((-)-2β-(1,2,4-oxadiazol-5-methyl)-3β-phenyltropane) is a phenyltropane derivative which acts as a potent monoamine reuptake inhibitor and stimulant drug. It is around 5x more potent a stimulant than cocaine, but is relatively unselective, binding to all three monoamine transporters although still with some selectivity for the dopamine transporter. RTI-126 has a fast onset of effects and short duration of action, and its pharmacological profile in animals is among the closest to cocaine itself out of all the drugs in the RTI series. Its main application in scientific research has been in studies investigating the influence of pharmacokinetics on the abuse potential of stimulant drugs
