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.

Our aim was the optimization of radiochemical parameters for the microfluidic preparation of [(18)F]altanserin. The four main parameters evaluated were (1) precursor concentration, (2) reaction temperature, (3) bolus flow rate through the microreactor and (4) bolus volume. For the determination

We have previously reported decreased frontal cortical serotonin2A receptor binding in 30 antipsychotic naïve first-episode schizophrenic patients and a relationship between this binding and positive psychotic symptoms. Until now, no longitudinal studies of serotonin2A receptor in first-episode antipsychotic-naïve schizophrenia patients

Postmortem investigations and the receptor affinity profile of atypical antipsychotics have implicated the participation of serotonin(2A) receptors in the pathophysiology of schizophrenia. Most postmortem studies point toward lower cortical serotonin(2A) binding in schizophrenic patients. However, in vivo studies of serotonin(2A)

The 5-hydroxytryptamine type 2a (5-HT(2A)) selective radiotracer [(18)F]altanserin has been subjected to a quantitative micro-positron emission tomography study in Lister Hooded rats. Metabolite-corrected plasma input modeling was compared with reference tissue modeling using the cerebellum as reference tissue. [(18)F]altanserin showed

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
