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