  名称：

  Modification of agonist binding moiety in hybrid derivative 5/7-{[2-(4-aryl-piperazin-1-yl)-ethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-1-ol/-2-amino versions: Impact on functional activity and selectivity for dopamine D2/D3 receptors

  摘要：

  The goal of the present study was to explore, in our previously developed hybrid template, the effect of introduction of additional heterocyclic rings (mimicking catechol hydroxyl groups as bioisosteric replacement) on selectivity and affinity for the D-3 versus D-2 receptor. In addition, we wanted to explore the effect of derivatization of functional groups of the agonist binding moiety in compounds developed by us earlier from the hybrid template. Binding affinity (K-i) of the new compounds was measured with tritiated spiperone as the radioligand and HEK-293 cells expressing either D-2 or D-3 receptors. Functional activity of selected compounds was assessed in the GTP gamma S binding assay. In the imidazole series, compound 10a exhibited the highest D-3 affinity whereas the indole derivative 13 exhibited similar high D-3 affinity. Functionalization of the amino group in agonist (+)-9d with different sulfonamides derivatives improved the D-3 affinity significantly with (+)-14f exhibiting the highest affinity. However, functionalization of the hydroxyl and amino groups of 15 and (+)-9d, known agonist and partial agonist, to sulfonate ester and amide in general modulated the affinity. In both cases loss of agonist potency resulted from such derivatization. (C) 2013 Elsevier Ltd. All rights reserved.
