Application

Mianserin hydrochloride has been used:
  • as a reversible antagonist for serotonergic -protein coupled receptor (GPCR) - G-protein protein-coupled receptor (S7.1R)
  • as an antidepressant in hippocampal astrocytes to test its effect on brain-derived neurotrophic factor (BDNF) mRNA expression
  • as a 5-hydroxytryptamine (5-HT) receptor antagonist to study its effect on serotonin modulation

Biochem/physiol Actions

Mianserin is a tetracyclic compound with sedative property. It lacks anticholinergic activity and is not effective on serotoninergic mechanisms. Mianserin is eliminated post biotransformation as hydroxylation, N-oxidation and N-demethylation products.
Antidepressant; antagonist/inverse agonist at 5-HT2 serotonin receptors; also blocks the H1 histamine receptor and the α2 adrenoceptor.

In order to test potential links with other stereospecific neurobiological effects of mianserin, the present study explored the stereospecificity for inhibition of depolarization-induced Ca2+ uptake by mianserin. Synaptosomes from rat hippocampus were incubated with 45Ca2+ in either resting or depolarizing

In this study, we demonstrate that clozapine and other atypical antipsychotic drugs induce a paradoxical internalization of 5-hydroxytryptamine-2A receptors in vitro and a redistribution of 5-hydroxytryptamine-2A receptors in vivo. We discovered that clozapine, olanzapine, risperidone and the putative atypical antipsychotic

Some in-vitro pharmacological effects of a novel analogue of mianserin, 2-carboxamidino-1,2,3,4,10,14b-hexahydrodibenzo (c,f) pyrazino (1,2-alpha) azepine hydrochloride (FCC5) have been studied. FCC5 was a non-competitive antagonist of both histamine-induced contractions of the guinea-pig ileum and 5-HT-induced contractions of rat fundal strips

Mirtazapine is a new antidepressant with a unique mode of action: it preferentially blocks the noradrenergic alpha2-auto- and heteroreceptors held responsible for controlling noradrenaline and serotonin release. In addition, mirtazapine has a low affinity for serotonin (5-HT)1A receptors but potently

This study examined the role of the serotonin 5-HT2 receptor in motor function by examining the effect of antagonists on the motor performance of a cranial nerve reflex, the nictitating membrane (NM) reflex of the rabbit. The NM reflex was
