  The Discovery of an Unusually Selective and Novel Cocaine Analog: Difluoropine. Synthesis and Inhibition of Binding at Cocaine Recognition Sites

  摘要：

  Cocaine is a stimulant drug with a high abuse liability. Although it inhibits several monamine transporters in the mammalian brain, its primary mechanism of action has been ascribed to its inhibition of the dopamine transporter. The synthesis, characterization, and receptor binding properties of all eight isomers of a unique tropane analog, 2-carbomethoxy-3-[bis(4-fluorophenyl)methoxy]tropane is described. In addition, we report that the S-enantiomer, (S)-(+)-2 beta-carbomethoxy-3 alpha-[bis(4-fluorophenyl)methoxy]tropane, Difluoropine, is a potent (IC50 10.9 nM) and selective (324 [DA/5HT]) ligand for the dopamine transporter.

  The compounds of the present invention comprise a tropane compound or ligand that selectively binds to tropane recognition sites, e.g., neuron transporters such as the DAT. The tropane ligand is radiolabeled with a radioactive technetium or rhenium by a chelating ligand which is attached to the tropane ligand by a linker.Tropane compounds or ligands useful in the pratice of the present invention can generally be represented by formula II where R1 and R2 are defined as above and where R1 can also be substituted at the C4 position of the tropane ring:Any tropane compound of the general formula II is useful in the present invention so long as it binds to DAT.Useful tropane analogs have a 3α-group, i.e., are of the boat configuration.Intermediates for the synthesis of the radiolabeled tropanes are claimed.

• Structure−Activity Relationship Comparison of (<i>S</i>)-2β-Substituted 3α-(Bis[4-fluorophenyl]methoxy)tropanes and (<i>R</i>)-2β-Substituted 3β-(3,4-Dichlorophenyl)tropanes at the Dopamine Transporter

  Extensive structure-activity relationships at the dopamine transporter (DAT) have been developed around two classes of tropane-based ligands. Opposing stereoselectivity and divergent structural requirements for optimal DAT binding suggest that these tropane-based DAT inhibitors may not access identical binding domains. To further investigate this hypothesis, a series of (S)-2beta-carboalkoxy-3alpha-(bis[4-fluorophenyl]methoxy)tropanes (11a-f, 13-16) and their identically (R)-2beta-substituted 3beta-(3,4-dichlorophenyl)tropanes (3, 5a-d) were prepared and evaluated for binding at the DAT and for inhibition of [H-3]dopamine uptake in rat brain. These studies showed that most of the identically 2-carboalkoxy-substituted analogues, within the two classes of compounds, bind with high affinity to DAT (K-i = 5.5 - 100 nM), albeit with opposite stereochemistry. However, the larger azido- (15) and isothiocyanato- (16) (S)-2beta-carbophenylethoxy-3alpha-(bis [4-fluorophenyl] methoxy)tropanes demonstrated a significant decrease in DAT binding potency (IC50 = 210 and 537 nM, respectively), suggesting that the DAT does not tolerate 2-position steric bulk in the benztropine class, as it does with the 2-substituted 3-aryltropanes. In addition, binding affinities at the serotonin transporter, norepinephrine transporter, and muscarinic receptors were evaluated and compared for compounds 2, 3, 11a-e, and 13. Together, the binding profiles across these systems demonstrated significant differences between these two classes of tropane-based ligands, which may be exploited toward the discovery of a cocaine-abuse pharmacotherapeutic.

Thus, the seven possible stereoisomers of (-)-cocaine have been synthesized and found to inhibit [3H]-2 beta-carbomethoxy-3 beta-(4-fluoro-phenyl)tropane [( 3H]WIN 35,428) with potencies ranging from 1/60 to 1/600 of that of (-)-cocaine.
