OncoFAP acetate

OncoFAP acetate is the highest-affinity small organic fibroblast activation protein (FAP) ligand reported to date, exhibiting a dissociation constant of 680 pM as measured by fluorescence polarization. OncoFAP derivatives, when administered intravenously in both fluorescent and radiolabeled forms, selectively accumulate in FAP-positive tumors while sparing normal tissues, enabling OncoFAP acetate to serve as modular components for targeted therapeutic delivery of radionuclides, CAR-T cells, or cytotoxic agents in oncology studies.
