An 18F-Alanine derivative serves as an ASCT2 marker for cancer imaging

Conclusion: The 18F-Ala-BF3 was successfully synthesized through one-step 18F-19F isotope exchange with fine specific activity and good radiochemical yield. Following in vitro bio-distribution and in vivo PET imaging in gastric tumor xenografts bearing mice and healthy mice revealed high tumor to normal tissue rate consist with fine tumor imaging of 18F-Ala-BF3. This study shed light on ASCT2 as a cancer biomarker for clinical diagnosis, and emphasized the usefulness of BAAs in tumor PET imaging. 18F-Ala-BF3 represents a useful molecular platform for tumor diagnosis.
