HLI373 dihydrochloride is a potent Hdm2 inhibitor, efficiently restraining the ubiquitin ligase activity of Hdm2 and effectively prompting apoptosis in DNA-damaging agent-sensitive tumor cells[1]. Additionally, HLI373 dihydrochloride exhibits antimalarial activity[2].
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
