  Bioisosteric Heterocyclic Versions of 7-{[2-(4-Phenyl-piperazin-1-yl)ethyl]propylamino}-5,6,7,8-tetrahydronaphthalen-2-ol: Identification of Highly Potent and Selective Agonists for Dopamine D3 Receptor with Potent in Vivo Activity

  摘要：

  In the current report, we extend the SAR study on our hybrid structure 7-{[2-(4-phenyl-piperazin-1-yl)ethyl]propylamino}-5,6,7,8-tetrahydronaphthalen-2-ol further to include heterocyclic bioisosteric analogues. Binding assays were carried out with HEK-293 cells expressing either D2 or D3 receptors with tritiated spiperone to evaluate inhibition constants (K). Functional activity of selected compounds in stimulating GTP gamma S binding was assessed with CHO cells expressing human D2 receptors and AtT-20 cells expressing human D3 receptors. The highest binding affinity and selectivity for D3 receptors were exhibited by (-)-34 (K-i = 0.92 nM and D2/D3 = 253). In the functional GTP gamma S binding assay, (-)-34 exhibited full agonist activity with picomolar affinity for D3 receptor with high selectivity (EC50 = 0.08 nM and D2/D3 = 248). In the in vivo rotational study, (-)-34 exhibited potent rotational activity in 6-OH-DA unilaterally lesioned rats with long duration of action, which indicates its potential application in neuroprotective treatment of Parkinson's disease.
