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.
The invention relates to novel chemical compounds and methods of making and using the same. In particular, the invention provides pyridazine compounds and/or related heterocyclic derivatives, compositions comprising the same, and methods of using pyridazine compounds and/or related heterocyclic derivatives and compositions comprising the same, for modulation of cellular pathways (e.g., signal transduction pathways), for treatment or prevention of inflammatory diseases (e.g., Alzheimer's disease), for research, drug screening, and therapeutic applications.
