General description

Methiothepin belongs to a new class of dibenzothiophenes. Methiothepin possesses neuroleptic activity.

Application

Methiothepin mesylate salt has been used to explore the relationship between circulating cells and the niche. It has also been used in serotonin (5-HT) and antagonists in vivo bioassays and in in vivo antagonist and lipopolysaccharide stimulations.

Biochem/physiol Actions

Methiothepin mesylate salt is a 5-HT1, 5-HT6, 5-HT7 serotonin receptor antagonist, which blocks serotonin autoreceptors.

Human uterine artery smooth muscle cells in culture were shown to express constitutively both 5-ht7 receptor mRNA and 5-ht7-like receptors functionally linked to cyclic AMP formation. 5-Carboxamidotryptamine (5-CT) and 5-HT enhanced forskolin-stimulated cyclic AMP accumulation in these cells, with pEC50

Conditioned taste aversion (CTA) learning induces the devaluation of a preferred food through its pairing with a stimulus inducing internal illness. In invertebrates, it is still unclear how this aversive learning impairs the memories of stimuli that had been associated
