  名称：

  Further delineation of hydrophobic binding sites in dopamine D2/D3 receptors for N-4 substituents on the piperazine ring of the hybrid template 5/7-{[2-(4-aryl-piperazin-1-yl)-ethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-ol

  摘要：

  Here we report a structure-activity relationship (SAR) study of analogues of 5/7-{[2-(4-aryl-piperazin-1-yl)- ethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-ol. Our SAR is focused on introduction of various substitutions in the piperazine ring of the hybrid template. The goal behind this study is to delineate the nature of the binding pocket for N-aryl substitution in the piperazine ring by observing the effect of various hydrophobic and other heteroaromatic substitutions on binding affinity (K-i), as measured with tritiated spiperone and HEK-293 cells expressing either D-2 or D-3 receptors. Functional activity of selected compounds was assessed with the GTP gamma S binding assay. Compound 8d was the most selective for the D-3 receptor in the spiperone binding assay. An interesting similarity in binding affinity was observed between isoquinoline derivative D-301 and the 2-substituted pyridine derivative 8d, suggesting the importance of relative spatial relationships between the N-atom of the ligand and the molecular determinants of the binding pocket in D-2/D-3 receptors. Functional activity assays demonstrated high potency and selectivity of (+)-8a and (-)-28b (D-2/D-3 (ratio of EC50): 105 and 202, respectively) for the D-3 receptor and both compounds were more selective compared to the reference drug ropinirole (D-2/D-3 (ratio of EC50): 29.5).

  摘要：

  The role of iron in the pathogenesis of Parkinson's disease (PD) has been implicated strongly because of generation of oxidative stress leading to dopamine cell death. In our overall goal to develop bifunctional/multifunctional drugs, we designed dopamine D2/D3 agonist molecules with a capacity to bind to iron. Binding assays were carried out with HEK-293 cells expressing either D2 or D3 receptor with tritiated spiperone to evaluate inhibition constants (K-i). Functional activity of selected compounds was carried out with GTP gamma S binding assay. SAR results identified compounds (+)-19a and (-)-19b as two Potent agonists for both D2 and D3 receptors (EC50 (GTP gamma S); D2 = 4.51 and 1.69 nM and D3 = 1.58 and 0.74 nM for (-)-19b and (+)-19a, respectively). In vitro complexation Studies with 19b demonstrated efficient chelation with iron. Furthermore, the deoxyribose assay with 19b demonstrated potent antioxidant activity. In PD animal model study, (-)-19b exhibited potent in vivo activity in reversing locomotor activity in reserpinized rats and also in producing potent rotational activity in 6-OHDA lesioned rats. This reports initial development of unique lead molecules that might find potential use in Symptomatic and neuroprotective treatment of PD.
