FAP-IN-2 (FAPI)

FAP-IN-2 is a 99mTc-labeled FAPI inhibitor designed for tumor imaging. It targets fibroblast activation protein (FAP) in the tumor microenvironment, enabling high-contrast SPECT imaging of FAP-expressing tumors. Its specificity, stability, and imaging capabilities make it a valuable tool for cancer diagnosis, staging, and research. Additionally, it has potential theragnostic applications in oncology.
