  Synthesis and Transporter Binding Properties of 3β-(4‘-Alkyl-, 4‘-alkenyl-, and 4‘-alkynylphenyl)nortropane-2β-carboxylic Acid Methyl Esters:  Serotonin Transporter Selective Analogs

  摘要：

  New methods for the synthesis of 3 beta-(4'-alkyl-, 4'-alkenyl-, and 4'-alkynylphenyl)nortropane-2 beta-carboxylic acid methyl esters 2-4, respectively, were developed. These methods involved coupling of the appropriate organometallic reagents to 3 beta-(4'-iodophenyl)tropane-2 beta-carboxylic acid methyl ester (6a, RTI-55) or to an N-protected derivative of 6a followed by N-demethylation or removal of the protecting group. Some analogs were prepared by catalytic reduction of the alkene and alkyne analogs 3 and 4 or by isomerization of the alkenes 3. The analogs 2-4 were evaluated for inhibition of radioligand binding to the serotonin (5-HT), dopamine (DA), and norepinephrine (NE) transporters. 3 beta-(4'-Isopropenyl- and 4'-cis-propenylphenyl)nortropane-2 beta-carboxylic acid methyl esters (3b,d), which possessed IC50 values of 0.6 and 1.15 nM, respectively, were the most potent analogs at the 5-HT transporter, and with NE/5-HT IC50 ratios of 240 and 128 nM, respectively, they were selective for the 5-HT relative to the NE transporter. Since interaction with the serotonin transporter may modulate the pharmacological effects resulting from binding to the dopamine transporter, 3 beta-(4'-isopropenylphenyl)tropane-2 beta-carboxylic acid methyl ester (11b) which has good affinity for both the 5-HT and DA transporters but low affinity at the NE transporter may be useful for studying this interaction.

  A series of compounds in the 4-fluoroalkyl-3-halophenyl nortropanes and 4-haloethenylphenyl tropane families are described as diagnostic and therapeutic agents for diseases associated with serotonin transporter dysfunction. These compounds bind to serotonin transporter protein with high affinity and selectivity. The invention provides methods of synthesis which incorporate radioisotopic halogens at a last step which permit high radiochemical yield and maximum usable product life. The radiolabeled compounds of the invention are useful as imaging agents for visualizing the location and density of serotonin transporter by PET and SPECT imaging.
