 note = {The synthesis of 11C-labelled peptide, cyclo[Arg-Gly-Asp-D-Tyr-Lys([1-11C]-Tpi)], from corresponding Trp-containing peptides via a Pictet-Spengler reaction by using [11C]formaldehyde is reported. Radiochemical yield of peptide at end of synthesis was 6.3±2.3% with a radiochemical purity of >98%, and the total synthesis time was about 35 min. The specific activity was 75.3±7.8 GBq/mol.},
