Description: 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
