  Synthesis and structure–activity relationship of 3β-(4-alkylthio, -methylsulfinyl, and -methylsulfonylphenyl)tropane and 3β-(4-alkylthiophenyl)nortropane derivatives for monoamine transporters

  摘要：

  Early studies led to the identification of 3 beta-(4-methoxyphenyl)tropane-2 beta-carboxylic acid methyl ester (5) with high affinity at the DAT (IC(50) = 6.5 nM) and 5-HTT (K(i) = 4.3 nM), while having much less affinity at the NET (K(i) = 1110 nM). In the present study, we replaced the 4'-methoxy group of the 3 beta-phenyl ring with a bioisosteric 4'-methylthio group to give 7a. We also synthesized a number of 3 beta-(4-alkylthiophenyl)tropanes 7b-e, 3 beta-(4-methylsulfinylphenyl) and 3 beta-(4-methylsulfonylphenyl)tropane analogues 7f-h as well as the 3 beta-(4-alkylthiophenyl)nortropane derivatives 8-11 to further characterize the structure-activity relationship of this type of compound for binding at monoamine transporters. With exception of the 4'-methylsulfonyl analogue 7h, all the tested compounds possessed high binding affinities at the 5-HTT. The K(i) values ranged from 0.19 nM to 49 nM. The 3 beta-(4-methylthiophenyl)tropane 7a and its N-(3-fluoropropyl) analogue 9a and N- allyl analogue 10a are the most selective compounds for the 5-HTT over the NET (NET/5-HTT = 314-364) in the series. However, none of the compounds showed selectivity similar to 5 for both the DAT and 5-HTT relative to the NET. This study provided useful SAR information for rational design of potent and selective monoamine transporter inhibitors. (C) 2009 Elsevier Ltd. All rights reserved.
