FAPI-X5
FAPI-X5 is a fibroblast activation protein (FAP) inhibitor. FAPI-X5 binds to the FAP catalytic domain, forming hydrogen bonds with key active residues and engaging in π-π stacking to drive functional inhibition. FAPI-X5 exhibits albumin binding activity to prolong systemic circulation half-life. FAPI-X5 induces cytostatic effects on glioblastoma tumors, slowing tumor growth without regression. FAPI-X5, when labeled with 68Ga, acts as a PET tracer with rapid tumor uptake and high-contrast imaging in glioblastoma tumor-bearing mice. FAPI-X5, when labeled with 177Lu or 47Sc, functions as a targeted radionuclide agent with prolonged tumor retention. FAPI-X5 can be used for the research of glioblastoma.

生物活性
FAPI-X5 (10 μg) when radiolabeled with 68Ga, 177Lu, or 47Sc exhibits >95% radiochemical purity, >40% albumin binding, and high in vitro stability, with 68Ga-FAPI-X5 showing the highest hydrophilicity and 177Lu- and 47Sc-FAPI-X5 showing slightly higher albumin binding[1].
FAPI-X5 (30-240 min) when radiolabeled with 68Ga, 177Lu, or 47Sc exhibits time-dependent cellular uptake in FAP-expressing U87MG cells, with 68Ga-FAPI-X5 showing the highest uptake at 2 h, and all variants reaching peak uptake by 4 h[1].

Result:Produced cytostatic effects with T/C values of 35.49% ± 3.8% at 18.5 MBq, 46.1% ± 4.7% at 37 MBq, and 57.2% ± 5.3% for 177Lu-FAPI-X5.
Produced cytostatic effects with T/C values of 37.50% ± 2.7% at 18.5 MBq, 36.8% ± 3.2% at 37 MBq, and 42.8% ± 3.6% for 47Sc-FAPI-X5.
Caused dose-dependent body weight loss, with a maximum loss of 11% at the 55.5 MBq 47Sc-FAPI-X5 dose, plateauing by day 10.
Resulted in one death in the 37 MBq 47Sc-FAPI-X5 group and one in the 55.5 MBq 177Lu-FAPI-X5 group.
Induced centrilobular coagulative necrosis of hepatocytes, ulcerative necrosis of intestinal mucosa, and mild inflammatory cell infiltration in cardiac and renal tissues.
