  New σ and 5-HT_1A Receptor Ligands:  ω-(Tetralin-1-yl)-n-alkylamine Derivatives

  摘要：

  Two series of compounds that are structurally related to benzomorphans, derived by structural modification of arylpiperazines with high 5-HT1A affinity and moderate a affinity, were prepared in order to increase a affinity and selectivity. All new compounds are N-substituted-omega-(1,2,3,4-tetrahydronaphthalen-1-yl)- or -omega-(1,2-dihydronaphthalen-4-yl)-n-alkylamines with, in some cases, a methoxy group on the tetralin moiety. They were tested in radioligand binding assays on sigma ([H-3]DTG and [H-3]-(+)-pentazocine), D-2 dopaminergic, 5-HT1A and 5-HT2 serotonergic, and PCP (phencyclidine) receptors. A first set of compounds bearing a 4-(1-substituted)piperazine moiety as terminal fragment on the alkyl chain showed moderate to high sigma affinity (K-i = 5.3-139 nM), the most active and selective being 1-cyclohexyl-4-[3-(5-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)-n-proyl]piperazine (14), with probable pronounced alpha(2) affinity (K-i = 5.3 nM on [H-3]DTG and K-i = 71 nM on [H-3]-(+)-pentazocine). Moreover, compound 13, a 1-benzylpiperazine analogue of 14, preserved a dual high 5-HT1A and sigma affinity (K-i = 3.6 nM on [H-3]-5-HT and K-i = 7.0 nM on [H-3]DTG). The second set of compounds includes some N-phenylalkyl derivatives of 3-(5-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)-n-propylamine that can be considered. to be open-chain derivatives of 4-substituted-1-arylpiperazines. Among these compounds that had a lower activity toward sigma binding sites, a high 5-HT1A affinity was found for the N-(3-phenylpropyl) derivative 21 (K-i = 4.4 nM) which demonstrated very good selectivity.

  摘要：

  为了增加5-HT1A对D-2，α1，σ和其他5-HT受体的选择性，合成了几种在侧链末端具有四氢萘部分的4-烷基-1-芳基哌嗪。许多变化已影响先前的类型3（1-芳基-4- [3-（1,2-二氢萘-4-基）-正丙基]哌嗪的结构。遵循几种合成程序以获得最终产物，这取决于双键以及侧链上杂原子的存在与否。在第一种情况下，可以广泛使用格利雅（Grignard）反应，而在第二种情况下，可以采用常规的合成方法。通过放射受体结合试验评估最终化合物对多巴胺D-1和D-2、5-羟色胺5-HT1A，5-HT1B，5-HT1C和5-HT2，α1肾上腺素和sigma受体的体外活性。

  N-[(tetralin-1-yl)alkyl]piperidines and a number of related N-di-n-propyl-[(tetralin-1-yl)alkyl]amines were prepared. Structural modifications such as piperidine substitutions, intermediate chain lengthening, and the nature of the aromatic ring were explored in order to identify structural requirements for selective sigma 1 affinity. They were tested in radioligand binding assays on sigma 1, 5-HT1A and 5-HT2

  N-[2-[4-(4-Chlorophenyl)piperazin-1-yl]ethyl]-3-methoxybenzamide (1), a high-affinity and selective dopamine D-4 receptor ligand, was chosen as a lead, and structural modifications were done on its amide bond and on its alkyl chain linking the benzamide moiety to the piperazine ring and by preparing some semirigid analogues. The binding profile at dopamine D-4 and dopamine D-2, serotonin 5-HT1A, and adrenergic ar receptors of 16 new compounds was determined. From the results emerged that the modification of the amide bond and the elongation of the intermediate alkyl chain caused a decrease in dopamine D-4 receptor affinity. All prepared semirigid analogues displayed D-4 receptor affinity values in the same range of the opened counterparts.

  The development of small molecules as P-gp modulating agents and SAR studies on these ligands represented the aim of the present work. A series of 6,7-dimethoxytetrahydroisoquinoline derivatives was prepared and their ability to inhibit P-gp activity has been evaluated. The basic nucleus of these compounds, common to the best P-gp inhibitors such as Tariquidar and Elacridar, has been functionalized with no-basic moiety from our studied sigma receptor ligands displaying potent P-gp inhibition. The best results were obtained for compounds 3c and 3a (EC50 = 1.64 and 4.86 mu M, respectively) and these results were remarkable because Elacridar showed in the same biological evaluation similar inhibitory activity (EC50 = 2 mu M). SAR studies displayed that the removal of double bond on the spacer or its shifting into tetraline ring decreased the P-gp inhibiting activity. Moreover, the P-gp inhibition mechanism of tested compounds was investigated by three selected biological experiments. The results displayed that only compound 3c was P-gp inhibitor as Elacridar, while compound 3a and reference compounds Cyclosporin A and Verapamil modulated P-gp activity saturating the efflux pump as substrates. Flow cytometry studies carried out in Doxorubicin resistant breast cancer cell line (MCF7/Adr) confirmed that compound 3c increased Doxorubicin cell accumulation 5.7-fold. In addition, in MCF7/ Adr, antiproliferative effect of 5 mu M Doxorubicin shifted from 5% to 95% when co-administered with compound 3c (20 mu M). The present study suggested a new class of small molecules displaying P-gp inhibitor activity differing from reference compounds Elacridar and Tariquidar for a simplified, and in the meantime, efficacious no-basic moiety.
