MedKoo Cat#: 408091 | Name: XL-188

Description:

WARNING: This product is for research use only, not for human or veterinary use.

XL-188 is a highly potent and selective inhibitor of USP7. XL188 inhibited USP7 catalytic domain and full-length enzyme with IC50 values of 193 and 90 nM, respectively. XL188 Promotes USP7-Dependent Loss of HDM2 and Increase of p53 and p21. XL188 represents one of only a small set of mammalian DUB inhibitors with low nanomolar potency and a high degree of selectivity relative to other DUBs

More Info
Ewing sarcoma is a pediatric cancer driven by EWS-ETS transcription factor fusion oncoproteins in an otherwise stable genomic background. The majority of tumors express wild-type TP53, and thus, therapies targeting the p53 pathway would benefit most patients.
