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.

BMC veterinary research, 15(1), 415-415 (2019-11-23)
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

[(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
Hubertus Hautzel et al.
NeuroImage, 58(3), 905-911 (2011-07-05)
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

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
