  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.

  We have recently shown that an arylaminopyridazine derivative of GABA, SR 95103 [2-(3-carboxypropyl)-3-amino-4-methyl-6-phenylpyridazinium chloride], is a selective and competitive GABA-A receptor antagonist. In order to further explore the structural requirements for GABA receptor affinity, we synthesized a series of 38 compounds by attaching various pyridazinic structures to GABA or GABA-like side

  我们最近发现，GABA的芳基氨基哒嗪衍生物SR 95103 [2-（3-羧丙基）-3-氨基-4-甲基-6-苯基吡啶并鎓氯化物]是一种选择性和竞争性的GABA-A受体拮抗剂。为了进一步探索对GABA受体亲和力的结构要求，我们通过将各种哒嗪结构连接到GABA或GABA样侧链上，合成了38种化合物。大多数化合物从大鼠脑膜中取代了[3H] GABA。所有活性化合物都拮抗了GABA引起的[3H]地西p结合的增强，强烈表明所有这些化合物都是GABA-A受体拮抗剂。从大鼠脑膜置换[3H] GABA的化合物均未与其他GABA识别位点（GABA-B受体，GABA吸收结合位点，谷氨酸脱羧酶，GABA转氨酶）相互作用。它们不与与GABA-A受体相关的Cl-离子载体相互作用，也不与苯并二氮杂str，士的宁和谷氨酸结合位点相互作用。因此，这些化合物似乎是特异性的GABA-A受体拮抗剂。就结构活性而言，可以得出结论，
