MedKoo CAT#: 205857

CAS#: 1072833-77-2

Description: Ixazomib, also known as MLN-2238, is a potent proteasome inhibitor (PI) with potential antineoplastic activity. MNL-2238 is also .the biologically active form of MLN9708. MLN2238 has an improved pharmacodynamic profile and antitumor activity compared with bortezomib in both OCI-Ly10 and PHTX22L models. Although both MLN2238 and bortezomib prolonged overall survival, reduced splenomegaly, and attenuated IgG2a levels in the iMyc(Cα)/Bcl-X(L) GEM model, only MLN2238 alleviated osteolytic bone disease in the DP54-Luc model.
