Application

Altanserin hydrochloride hydrate has been used in the pretreatment of rat brain samples and as a non-radioactive control in the calibration curve preparation for quantifying [18F]altanserin in high-performance liquid chromatography.
Altanserin hydrochloride hydrate is a specific 5-HT2/serotonergic antagonist and has been used in a study to assess serotonin release capacity in the human brain.

Biochem/physiol Actions

The radioligand of altanserin, [18F]altanserin is useful as a positron emission tomography (PET)-radioligand for the visualization and quantification of serotonin2A (5-HT2A) receptors.
Altanserin hydrochloride hydrate is a specific 5-HT2/serotonergic antagonist.

Postmortem studies show reductions in brain serotonin 2A (5-HT(2A)) receptors in Alzheimer's disease (AD). Converging evidence also suggests that serotonergic dysregulation may contribute to behavioral symptoms that frequently occur in AD. This study aimed to define regional reductions in 5-HT(2A)

Sex-hormones influence brain function and are likely to play a role in the gender predisposition to mood and anxiety disorders. Acute fluctuations of sex-hormone levels including hormonal replacement therapy appear to affect serotonergic neurotransmission, but it is unknown if baseline

Serotonin and its cerebral receptors play an important role in sleep-wake regulation. The aim of the current study is to investigate the effect of 24-h total sleep deprivation on the apparent serotonin 2A receptor (5-HT(2A)R) binding capacity in the human

Although alterations of serotonin (5-HT) system functioning have been proposed for a variety of psychiatric disorders, a direct method quantitatively assessing 5-HT release capacity in the living human brain is still lacking. Therefore, we evaluated a novel method to assess

Currently, [18F] altanserin is the most frequently used PET-radioligand for serotonin2A (5-HT2A) receptor imaging in the human brain but has never been validated in dogs. In vivo imaging of this receptor in the canine brain could improve diagnosis and therapy
