MLN2238 inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome with IC50 and Ki of 3.4 nM and 0.93 nM, respectively, also inhibits the caspase-like (β1) and trypsin-like (β2) proteolytic sites, with IC50 of 31 and 3500 nM. MLN2238 is a selective, potent, and reversible inhibitor of the proteasome in tumor cells. MLN2238 shows time-dependent reversible proteasome inhibition. |
