| Abstract | Integrin alpha(v)beta(3), a cell adhesion molecule, plays a key role in angiogenesis and tumor cell metastasis and is therefore an important target for new therapeutic and diagnostic strategies. Since ROD bind to alpha(v)beta(3) particularly, a lot of ROD containing peptides were radiolabeled and evaluated as imaging or therapeutic agents. In this study, a new Re-188-RGD peptide analog was synthesized and characterized. Within 30 min, the Re-188-H-E[c(RGDyK)](2) was obtained in radiochemical purity of better than 95%. The His-E[c(RGDyK)](2) had a good integrin-binding affinity (50% inhibitiory concentracer (IC50=46.5x10(-9) nm) and exhibited active accumulation (7.20 +/- 1.06) in S180 tumor. Because of relatively fast washout in blood and normal tissues, the target/non-target ratio was high. Further experiments to improve the tumor targeting efficacy and in vivo kinetic profiles are in progress towards developing it into a promising radio agent. |
