NH2-UAMC1110 TFA is an aminobutoxy derivative of the fibroblast activation protein (FAP) inhibitor UAMC1110 (HY-100684), and is a precursor compound for the synthesis of FAP inhibitor probes, not directly used in bioactivity experiments. For example, NH2-UAMC1110 TFA is involved in the synthesis of the radiotracer FAPI-QS, which exhibits high tumor selectivity and high dose effect, and has been used in tumor diagnosis. NH2-UAMC1110 TFA structurally incorporates an active amino group, allowing it to form covalent bonds with various molecules (such as DOTA, DATA5m, radionuclide chelators, etc.) to synthesize molecular imaging probes or targeted compounds with the ability to target FAP. NH2-UAMC1110 TFA specifically binds to the FAP active site, inhibiting its proline-selective serine protease activity (including dipeptidyl peptidase and endopeptidase activity), blocking FAP-mediated tissue remodeling-related processes. Its key activity is high targeting and high affinity, and its core function is to act as a targeting module coupled with bifunctional chelators (such as DOTA, DATA5m). NH2-UAMC1110 TFA can be applied to diagnostic imaging studies of tumors expressing FAP (such as colorectal cancer, pancreatic cancer, etc.), and also provides molecular tools for targeted research of FAP-related diseases with high FAP expression, such as fibrosis and arthritis .
