  Synthesis and biological evaluation of 6-aryl-6 H -pyrrolo[3,4- d ]pyridazine derivatives: high-affinity ligands to the α 2 δ subunit of voltage gated calcium channels

  摘要：

  A novel class of 6-aryl-6H-pyrrolo[3,4-d]pyridazine ligands for the alpha(2)delta subunit of voltage-gated calcium channels has been described. Substitutions in the aryl ring of the molecule were generally not tolerated, and resulted in diminished binding to the alpha(2)delta subunit. Modifications to the pyridazine ring revealed numerous permissive substitutions, and detailed SAR studies were carried out in this portion of the molecule. Replacement of the pyridazine ring methyl group with an aminomethyl functionality provided greatly improved potency over the initial lead. The initial lead compound displayed good rat pharmacokinetic properties, and was shown to be efficacious in the Chung model for neuropathic pain in rats. (C) 2004 Elsevier Ltd. All rights reserved.
