Kinase experiment: | To determine compound IC50s, FT827 is diluted in 100% DMSO in three-fold 12- point dilution series from 100 µM. 100 nL of 100-fold concentrated solutions are dispensed into black 384-well plate. 25 nM ubiquitin-rhodamine 110, along with recombinant USP7CD (3 nM), or USP7C-term (30-125 pM, depending on batch activity) are added and the plates incubated at room temperature for 1 h. The reaction is terminated by adding 2.5 µL citric acid to a final concentration of 10 mM prior to measuring fluorescence intensity on a Pherastar with a 485 nm excitation/520 nm emission optic module[1]. |

FT827 is a selective and covalent ubiquitin-specific protease 7 (USP7) inhibitor with an IC50 of 52 nM.
FT827 features a vinylsulfonamide moiety that covalently modifies the catalytic Cys223 of USP7 and inhibits the enzyme with Ki and Kd of 7.8 and 4.2 μM, respectively. FT827 exclusively inhibit USP7 in a panel of 38 deubiquitinases (DUBs) from diverse families. FT827 inhibits USP7 probe reactivity with IC50s of 0.1-2 µM, confirming 10 to 100-fold higher potency as compared to P22077 in crude cell extracts or with intact MCF7 breast cancer cells, followed by incubation with the ubiquitin active site suicide probe haemagglutinin (HA)-tagged ubiquitin bromoethyl (HA-UbC2Br)[1].

Molecular basis of USP7 inhibition by selective small-molecule inhibitors
Nature 2017 Oct 26;550(7677):481-486.PMID:29045389DOI:PMC6029662
Ubiquitination controls the stability of most cellular proteins, and its deregulation contributes to human diseases including cancer. Deubiquitinases remove ubiquitin from proteins, and their inhibition can induce the degradation of selected proteins, potentially including otherwise 'undruggable' targets. For example, the inhibition of ubiquitin-specific protease 7 (USP7) results in the degradation of the oncogenic E3 ligase MDM2, and leads to re-activation of the tumour suppressor p53 in various cancers. Here we report that two compounds, FT671 and FT827, inhibit USP7 with high affinity and specificity in vitro and within human cells. Co-crystal structures reveal that both compounds target a dynamic pocket near the catalytic centre of the auto-inhibited apo form of USP7, which differs from other USP deubiquitinases. Consistent with USP7 target engagement in cells, FT671 destabilizes USP7 substrates including MDM2, increases levels of p53, and results in the transcription of p53 target genes, induction of the tumour suppressor p21, and inhibition of tumour growth in mice.
