(–)-2β-Carbomethoxy-3β-(4-bromophenyl)tropane (RTI-51, bromopane) is a semi-synthetic alkaloid in the phenyltropane group of psychostimulant compounds. First publicized in the 1990s, it has not been used enough to have gained a fully established profile. RTI-51 can be expected to have properties lying somewhere in between RTI-31 and RTI-55. Importantly it has a ratio of monoamine reuptake inhibition of D > S > N (1.8:10.6:37.4nM respectively) which is an unusual balance of effects not produced by other commonly used compounds (although RTI-121 is similar, but more DAT selective). It has been used in its 76Br radiolabelled form to map the distribution of dopamine transporters in the brain.
Modern research seems to confirm the above hypothesis. However, earlier work produced more scattered results. Based upon what is obvious from the table, RTI-31, RTI-51, and RTI-55 are all similarly potent TRIs.
Data in Above table from rats brains (1995). More recent work has advocated using cloned human transporter/s.
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
