| Description | C527 is a potent pan DUB enzyme inhibitor with a high affinity for the USP1/UAF1 complex (IC50=0.88 μM). |
| Targets&IC50 | USP1:0.88 μM |
| In vitro | C527 inhibits the DUB activity of the USP12/USP46 complex and other DUB enzymes in vitro. However, the IC50 of C527 for these DUB enzymes was higher in comparison with USP1/UAF1 complex. C527 has considerably less inhibitory effect on UCH-L1 and UCH-L3, a different subclass of DUB enzymes. C527 treatments causes an increase in the levels of Ub-FANCD2 and Ub-FANCI and it also lead to an increase in ubiquitinated forms of FANCD2 and FANCI, cause a decrease in homologous recombination activity, and sensitize cells to DNA damaging agents[1]. Pretreatment of USP1/UAF1 with C527 resulted in inhibition of its enzyme activity with an IC50 of 0.88±0.03 μM. Pretreatment of cells with the C527 causes an enhancement in the cytoxicity of mitomycin C and camptothecin. |
