Synthesis and Monoamine Transporter Binding of 2-(Diarylmethoxymethyl)-3β-aryltropane Derivatives
摘要:
3beta-Aryltropane analogues wherein the 2-position was substituted with various diarylmethoxy-alkyl groups were synthesized and evaluated for binding at the dopamine transporter (DAT), serotonin transporter (SERT), norepinephrine transporter (NET), and muscarinic (M-1) receptors. The 2beta-analogues 9a-i generally demonstrated high to moderate binding affinities (K-i = 34112 nM) at the DAT with good selectivity over SERT, NET, and M-1 receptors. Alternatively, the 2alpha-isomers 10a-i were 10-fold less potent at the DAT with poor selectivity over SERT. These SAR studies provide further evidence for the varied binding requirements of structurally diverse tropane-based ligands and support future studies to elucidate DAT binding requirements in relation to cocaine-like behavioral endpoints.

3-tolyltropane derivatives were synthesized, and the in vitro and in vivo biological activities as dopamine uptake inhibitors were determined. From the in vitro structure-activity data, it is apparent that a tolyl group in the 2-position, independent of the stereochemical attachment to the tropane ring system, provided compounds (9-12, 14) that exhibit high-affinity binding at the dopaminetransporter (DAT)
