IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.
AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.
English(3-Methoxy-naphthalen)-2-yl-(1-benzyl-piperidin)-4-yl-acetate (SB-235753) was labelled with 11C (t(1/2) = 20.4 min) as a putative radioligand for the non-invasive assessment of Dopamine D4 receptors in vivo with positron emission tomography (PET). The precursor for the radiosynthesis 3-hydroxynaphthyl-2-[(N-benzyl)-piperidyl]-acetate hydrochloride was prepared by a four-step synthesis starting from ethyl-4-pyridyl acetate. The radiolabelling consisted of methylation with [11C]methyltriflate in dimethylformamide in the presence of potassium hydroxide. [11C]SB-235753, was synthesised in 30 min with a radiochemical yield of 10 ± 5% (EOS, non-decay corrected) with 99% radiochemical purity and specific radioactivity of 10 ± 3 Ci/μmol. Biodistribution studies in rats with [11C]SB-235753 showed the uniform distribution of the tracer within different areas of the murine brain. At 30 min after injection 99% of the radioligand in plasma and 100% in cerebellum was metabolised. These findings suggest that [11C]SB-235753 can not be a suitable tracer for dopamine D4 receptor studies with PET.
