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.

This invention relates to a method for controlling undesirable monocotyledonous and dicotyledonous plant species by applying to the foliage thereof or to soil containing seeds or other propagating organs of said plant species, a herbicidally-effective amount of a pyridazine compound. The invention also relates to novel herbicidally-effective pyridazine compounds.
