We have successfully achieved the preparation of cyclo[Arg-Xaa-Asp-D-Tyr-Lys([1-11C]Tpi)](Xaa=Gly or Ala) using carbon-11 formaldehyde. This labeling technique could be used to increase the overall utility of 11C-labeled oligopeptides as PET probes because this method allows for the incorporation of carbon-11 into a cyclic bond. Furthermore, our study provide that cyclo[Arg-Gly-Asp-D-Tyr-Lys([1-11C]Tpi)] enabled accumulation in pancreatic cancer cell line BxPC3.
