NOTA-FAPI is a fibroblast activation protein (FAP) inhibitor and structural analogue of FAPI-4. NOTA-FAPI-4 serves as a diagnostic and therapeutic tool for diseases characterized by FAP overexpression, including its application as a positron emission tomography (PET) tracer for noninvasive imaging of FAP-associated pathological conditions and monitoring of therapeutic responses.

| Description | NOTA-FAPI is a fibroblast activation protein (FAP) inhibitor and structural analogue of FAPI-4. NOTA-FAPI-4 serves as a diagnostic and therapeutic tool for diseases characterized by FAP overexpression, including its application as a positron emission tomography (PET) tracer for noninvasive imaging of FAP-associated pathological conditions and monitoring of therapeutic responses. |
| In vitro | In U87MG cells, Al18F-NOTA-FAPI-4 exhibited the highest uptake rate (2.13±0.17 AD%) at 10 minutes, and this uptake could be blocked by unlabeled precursors. The IC50 value of NOTA-FAPI-4 was 1.73±0.93 nM, indicating its high affinity for FAP [1]. |
| In vivo | In KM mice, Al18F-NOTA-FAPI demonstrated rapid renal clearance and low uptake in most normal organs. In U87MG tumor-bearing mice, the uptake in the tumor region was relatively high (35.29±1.00%ID/g), with a 33.72% decrease in uptake observed between 1 hour and 4 hours [1]. |
