FT671 is a potent and selective inhibitor of ubiquitin-specific protease 7 (USP7) with an IC50 value of 52nM[1]. USP7 can deubiquitinate MDM2, resulting in a decrease in the intracellular level of p53[2]. FT671 has anti-tumor activity[3].
In vitro, pretreatment of A549 cells with FT671 (0-24µM) for 4h significantly promoted the degradation of intracellular SP1 and β-Catenin proteins[4]. Treatment of colorectal cancer HCT116 cells with FT671 (10µM) for 5min significantly attenuated intracellular protein ubiquitination under the condition of USP7 knockdown[5].
In vivo, oral treatment of MM.1S cell xenograft mice with FT671 (100, 200mg/kg) significantly inhibited the growth of tumors in mice in a dose-dependent manner and was well tolerated[6].

| Cell experiment [1]: | |
Cell lines | A549 cells |
Preparation Method | A549 cells were pretreated with FT671(0, 2, 4, 8, 16, 24µM) for 4h, and then treated with 50μg/mL cycloheximide (CHX) for 0-24h, and the protein was used for Western blot analysis. |
Reaction Conditions | 0, 2, 4, 8, 16, 24µM; 4h |
Applications | FT671 significantly promoted the degradation of both SP1 and β-Catenin in A549 cancer cells. |
| Animal experiment [2]: | |
Animal models | Non-obese diabetic-severe combined immunodeficient (NOD-SCID) mice |
Preparation Method | 6 to 8-week-old female NOD SCID mice were irradiated (2Gγ) with a Co60 irradiator source 24h prior to subcutaneous inoculation of 5×106 MM.1S tumor cells in 1:1 mixture of RPMI-1640 and Matrigel. The efficacy study was initiated when tumors had reached an average volume of 159 mm3. Tumour-bearing mice were randomly assigned to treatment groups such that each treatment group had the same average tumor volume. Mice received a lead-in dose of 25mg/kg of FT671 24h prior to starting on the dosing regimen of 100 or 200mg/kg FT671 (once a day, per os by oral gavage). 10% DMA/90% PEG400 served as a vehicle control. For the statistical analysis of differences in tumor volumes between treatment groups, a 2-way ANOVA with repeated measures was performed followed by correction for multiple comparisons using statistical hypothesis testing (Tukey). |
Dosage form | 100, 200mg/kg/day; p.o. |
Applications | Treatment of mice with FT671 led to significant dose-dependent tumor growth inhibition. FT671 was well tolerated even at high doses, and no significant weight loss or cachexia was observed during the study. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
