  3-Aminopyridazine derivatives with atypical antidepressant, serotonergic and dopaminergic activities

  摘要：

  Minaprine [3-[(beta-morpholinoethyl)amino]-4-methyl-6-phenylpyridazine dihydrochloride] is active in most animal models of depression and exhibits in vivo a dual dopaminomimetic and serotoninomimetic activity profile. In an attempt to dissociate these two effects and to characterize the responsible structural requirements, a series of 47 diversely substituted analogues of minaprine were synthesized and tested for their potential antidepressant, serotonergic, and dopaminergic activities. The structure-activity relationships show that dopaminergic and serotonergic activities can be dissociated. Serotonergic activity appears to be correlated mainly with the substituent in the 4-position of the pyridazine ring whereas the dopaminergic activity appears to be dependent on the presence, or in the formation, of a para-hydroxylated aryl ring in the 6-position of the pyridazine ring.

  作为新型大麻素受体2型反向激动剂的新型哒嗪酮-4-羧酰胺：合成，药理学数据和分子对接

  摘要：

  在最近几年中，大麻素2型受体（CB 2 R）选择性配体已显示出作为新型治疗药物在多种疾病中的巨大潜力。为了发现新的选择性大麻素配体，设计并合成了一系列哒嗪酮-4-羧酰胺，并测试了这些新衍生物对h CB 1 R和h CB 2 R的亲和力。6-（4-氯-3-甲基苯基）-2-（4-氟苄基）-N-（顺式4-甲基环己基）-3-氧代-2,3-二氢哒嗪-4-羧酰胺（9）显示出高CB 2-亲和力（K i CB 2个 ＝ 2.0±0.81nM）和显着的选择性（K i CB 1 / K i CB 2  > 2000）。此外，在[ 35 S]-GTPγS结合试验中，已经证明9个和其他活跃的新合成实体具有CB 2 R反向激动剂的作用。新合成的CB 2 R配体的ADME预测表明其药代动力学特征良好。对接研究揭示了这些衍生物相互作用的具体模式。我们的结果支持哒嗪酮-4-羧酰胺代表了一种有效的和选择性的CB 2 R配体发展的新有希望的支架。
