RTI-112 (2β-carbomethoxy-3β-(3-methyl-4-chlorophenyl)tropane) is a synthetic stimulant drug from the phenyltropane family. In contrast to RTI-113, which is DAT selective, RTI-112 is a nonselective triple reuptake inhibitor.
In vitro tests show a very similar serotonin transporter (SERT)/dopamine transporter (DAT)/norepinephrine transporter (NET) selectivity to cocaine, although in vivo behaviour is different:
"The nonselective monoamine transporter inhibitor RTI-126 and the DAT-selective inhibitors RTI-150 and RTI-336 both had a faster rate of onset (30 min) and a short duration of action (4h). In contrast, the nonselective monoamine transporter inhibitor RTI-112 had a slower rate of onset (30–60 min) and a longer duration of action (10h). The DAT-selective inhibitors RTI-171 and RTI-177 also had slower rates of onset (30–120 min), but RTI-171 had a short duration of action (2.5 h) while RTI-177 had a very long duration of action (20 h)."
The efficacy of cocaine analogs to elicit self-administration is related to the rate at which they are administered. Slower onset analogs are less likely to function as behavioral stimulants than analogs eliciting a faster rate of onset. Nonselective analogs are less likely to function as "reinforcers" than reuptake inhibitors that have DAT specificity.
You know you're livin' a lie when you just can't win
Pulling in first prize ain't gonna give you a break
You know I'm kickin' back, I had a broken wing
Me and my shadow are the next best thing
I need someone
You know it might take more than you give to me
Are you gun-shy, are you listening?
What we got here is dead reckoning
And take me in for the night in the right time zone
We'll do what you like, make a left turn home
I put out the light, you're turnin' way too red
No stop sign straight up ahead
You need so much
So much sympathy
That's more than I can say
You know it's not too late
Are you gun-shy, are you listening?
What we got here is dead reckoning
And if it feels good, we'll do it again
See your way clear, dead reckoning
Tell me why, tell me why
Are you listening?
Are you listening?
Are you listening?
Are you listening?
You mean so much
So much to me
That's more than I can say
You know it's not too late
Are you gun-shy, are you listening?
What we got here is dead reckoning
And if it feels good, we'll do it again
See your way clear, dead reckoning, yeah
What we got here is dead reckoning
