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.[1]
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.[2]
Altanserin hydrochloride hydrate is a specific 5-HT2/serotonergic antagonist.

[(18)F]Altanserin, an important PET radioligand for the in vivo imaging of the 5-HT(2A) receptor, was synthesized from its precursor nitro-altanserin in DMF or DMSO at high temperatures of 150 degrees C in an overall radiochemical yield (EOB) of 23-25% after

Behavioral and cellular studies indicate that serotonin interacting with the 5-HT2a receptor (5-HT2aR) is involved in cognitive processes supporting working memory (WM). However, 5-HT receptor neuroimaging studies directly relating WM-induced neuronal activations to concomitant changes in the availability of 5-HT

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

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

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)
