FT671 is a non-covalent, selective USP7 inhibitor (IC50=52 nM) that binds to the catalytic domain of USP7 (Kd=7.8 µM). It disrupts the stability of USP7 substrates including MDM2, elevates p53, induces p21, and inhibits tumor growth in mice.

| In vitro | FT671 induces degradation of N-Myc protein and upregulation of p53 protein in the neuroblastoma cell line IMR-32. FT671 can elevate p53 protein levels in HCT116 colon carcinoma cells or the osteosarcoma (U2OS) cell line, thereby inducing the expression of p53 target genes, including BBC3 (encoding PUMA protein), CDKN1A (p21), RPS27L (S27L), and MDM2. FT671 also stabilizes p53 protein by enhancing MDM2 ubiquitination in the MM.1S multiple myeloma cell line, consequently promoting the expression of p53 target genes. |
| In vivo | FT671 (100 mg/kg and 200 mg/kg, oral gavage, daily) demonstrated significant dose-dependent tumor growth inhibition in mice. |
