Biologische Aktivität
6-(4-methoxyphenyl)-3-pyridazinamine is a gabaa receptor antagonist.ionotropic gabaa receptors are ligand-gated ion channels that facilitate the passing of chloride ions across the cell membrane and promote an inhibitory influence on target neurons. these receptors are the major targets for benzodiazepines and related anxiolytic drugs.
in vitro
6-(4-methoxyphenyl)-3-pyridazinamine is an intermediate in the synthesis of sr 95103 [2-(3-carboxypropyl)-3-amino-4-methyl-6-phenylpyridazinium chloride]. sr 95103 was identified as a selective and competitive gaba-a receptor antagonist. moreover, sr 95103 was shown to be able to displace [3h]gaba from rat brain membranes with an apparent ki of 2.2 μm. in addition, sr 95103 was found, on the basis of biochemical, electrophysiological, and pharmacological results, to be a selective and competitive antagonist of gaba at the gaba-a receptor site [1].
in vivo
the behavioral effects of unilateral microinjections of sr 95103 into periventricular structures were studied. results showed that when injected into the medial hypothalamus (mh) or into the dorsal part of the mesencephalic central gray (cg), sr 95103 produced a dose-dependent behavioral activation together with jumps. the behavioral activation was found to be attenuated by pretreatment with thip, a gaba receptor agonist [2].
