  muscimol或thiomuscimol与氨基哒嗪的缩合产生GABA-A拮抗剂。

  摘要：

  通过将6-芳基-3-氨基哒嗪与（氯甲基）异恶唑或（氯甲基）异噻唑衍生物进行N 2烷基化反应，制备了氨基官能团在local胺基体系中离域的十种麝香酚和硫代麝香酚类似物。这些muscimol和thiomuscimol衍生物显示出对GABA-A受体的强效结合特性（它们取代了[3H] GABA和[3H] gabazine）并在静脉注射后引起惊厥。它们与我们小组提出的GABA-A拮抗剂模型药效基团非常吻合，并显示出与哒嗪基-GABA相似的结构活性图谱。

  A series of 4-(6-imino-3-aryl/heteroarylpyridazin-1-yl) butanoic acids were synthesized and examined for antagonism of GABA receptors from three insect species. When tested against small brown planthopper GABA receptors, the 3,4-methylenedioxyphenyl and the 2-naphthyl analogues showed complete inhibition of GABA-induced fluorescence changes at 100 mu M in assays using a membrane potential probe. Against common cutworm GABA receptors, these analogues displayed approximately 86% and complete inhibition of GABA-induced fluorescence changes at 100 mu M, respectively. The 4-biphenyl and 4-phenoxyphenyl analogues showed moderate inhibition at 10 mu M in these receptors, although the inhibition at 100 mu M was not complete. Against American cockroach GABA receptors, the 4-biphenyl analogue exhibited the greatest inhibition (approximately 92%) of GABA-induced currents, when tested at 500 mu M using a patch-clamp technique. The second most active analogue was the 2-naphthyl analogue with approximately 85% inhibition. The 3-thienyl analogue demonstrated competitive inhibition of cockroach GABA receptors. Homology modeling and ligand docking studies predicted that hydrophobic 3-substituents could interact with an accessory binding site at the orthosteric binding site. (C) 2012 Elsevier Ltd.

  Starting from the commercially available 3-amino-6-chloropyridazine, 3-amino-6-arylpyridazines were prepared in good yields by means of a Suzuki cross-coupling reaction avoiding the somewhat lengthy four-step classic synthesis. (C) 2001 Elsevier Science Ltd. All rights reserved.
