f-5446

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

F5446 is a selective small molecule SUV39H1 methyltransferase inhibitor. It promotes apoptosis in colorectal cancer cells by inhibiting the deposition of H3K9me3 on the FAS promoter to increase Fas expression, while inhibiting CTL effector gene expression.
