Synthesis of radiolabeled stilbene derivatives as new potential PET probes for aryl hydrocarbon receptor in cancers

New carbon-11 and fluorine-18 labeled stilbene derivatives, cis-3,5-dimethoxy-4′-[11C]methoxystilbene (4′-[11C]8a), cis-3,4′,5-trimethoxy-3′-[11C]methoxystilbene (3′-[11C]8b), trans-3,5-dimethoxy-4′-[11C]methoxystilbene (4′-[11C]10a), trans-3,4′,5-trimethoxy-3′-[11C]methoxystilbene (3′-[11C]10b), cis-3,5-dimethoxy-4′-[18F]fluorostilbene (4′-[18F]12a), and trans-3,5-dimethoxy-4′-[18F]fluorostilbene (4′-[18F]13a), were designed and synthesized as potential PET probes for aryl hydrocarbon receptor (AhR) in cancers.
