  Synthesis, pharmacological evaluation and molecular modeling studies of triazole containing dopamine D3 receptor ligands

  摘要：

  A series of 2-methoxyphenyl piperazine analogues containing a triazole ring were synthesized and their in vitro binding affinities at human dopamine D-2 and D-3 receptors were evaluated. Compounds 5b, 5c, 5d, and 4g, demonstrate high affinity for dopamine D-3 receptors and moderate selectivity for the dopamine D-3 versus D-2 receptor subtypes. To further examine their potential as therapeutic agents, their intrinsic efficacy at both D-2 and D-3 receptors was determined using a forskolin-dependent adenylyl cyclase inhibition assay. Affinity at dopamine D-4 and serotonin 5-HT1A receptors was also determined. In addition, information from previous molecular modeling studies of the binding of a panel of 163 structurally-related benzamide analogues at dopamine D-2 and D-3 receptors was applied to this series of compounds. The results of the modeling studies were consistent with our previous experimental data. More importantly, the modeling study results explained why the replacement of the amide linkage with the hetero-aromatic ring leads to a reduction in the affinity of these compounds at D-3 receptors.

  derivative, for which a single crystal X-ray structure was obtained, showed high and selective affinity toward α1A, α1D, and α2C adrenergic receptors with Ki values of 17, 21, and 39 nM, respectively. A method to prepare the corresponding 99mTc complex was also developed where the resulting metallocarborane was shown to be stable and is therefore suitable for in vivo molecular imaging studies.

  A series of new aporphine analogues (aporlogues) were prepared from appropriate aporphine precursors and arylpiperazines using the Click reaction protocol. These compounds displayed good to high affinity at the D-3 receptor, low or no affinity at the D-1 and D-2 receptors. Compounds 7f and 11c stood out as the most potent at the D-3 receptor among our newly synthesized aporlogues with K-i values of 2.67 and 1.14 nM, respectively. Further assay at the 5-HT1A receptor revealed that aporlogues 7f and 11c also showed high affinity at this receptor with K-i values of 9.68 and 7.59 nM, respectively. They were 3.6- and 6.6-fold more potent at the D-3 over 5-HT1A receptors. Such D-3/5-HT1A dual property of these compounds may be useful in the treatment of several brain disorders.

  A series of new 1-aryl-3-benzazepine derivatives containing an arylpiperazinyl function as the N3 substituent were synthesized by combining a D-1 receptor agonistic pharmacophore and a 5-HT1A receptor pharmacophore through Click reaction. Interestingly, these compounds generally do not have good binding affinity at the D-1 receptor, but most compounds are potent at both D-2 and 5-HT1A receptors. Compound 8h, containing 1-m-tolyl-benzazepine scaffold and 2-methoxyphenylpiperazine core, displayed good affinity at all tested receptors, with K-i values of 144, 80, and 133 nM, for the D-1, D-2, and 5-HT1A receptors, respectively. Compound 13 with the triazole moiety formed differently from that in 8h showed the highest affinity at the D-2 receptor with K-i value of 19 nM. This compound also showed moderate affinity at the 5-HT1A (K-i, 105 nM), and D-1 (K-i, 551 nM) receptors. Functional assays indicated that both compounds 13 and 8h are antagonists at D-1 and D-2 receptors, whereas full agonistic activity at the 5-HT1A receptor was observed. In agreement with the binding affinity, compound 13 is a high efficacy D-2 antagonist and 5-HT1A agonist. (C) 2009 Elsevier Ltd. All rights reserved.

  Simultaneous targeting of dopamine D-2 and 5-HT2A receptors for the treatment of schizophrenia is one key feature of typical and atypical antipsychotics. In most of the top-selling antipsychotic drugs like aripiprazole and risperidone, high affinity to both receptors can be attributed to the presence of 1,4-disubstituted aromatic piperazines or piperidines as primary receptor recognition elements. Taking advantage of our in-house library of phenylpiperazine-derived dopamine receptor ligands and experimental data, we established highly significant CoMFA and CoMSIA models for the prediction of 5-HT2A over D-2 selectivity. Subsequently, the models were applied to identify the selective candidates 55-57 from our newly synthesized library of GPCR ligands comprising a pyrazolo[1,5-a]pyridine head group and a 1,2,3-triazole based linker unit. The test compound 57 showed subnanomolar a K-i value (0.64 nM) for 5-HT2A and more than 10- and 30-fold selectivity over the dopamine receptor isoforms D-2S and D-2L, respectively.
