MLN9708

SKU: orb1306735

Description

MLN2238, the biologically active form of Ixazomib (MLN9708), is a potent and selective inhibitor of the 20S proteasome's chymotrypsin-like (β5) activity (Ki50=0.93 nM, IC50=3.4 nM). This investigational small molecule is widely used in preclinical research, including in vitro cell-based assays and in vivo xenograft models, to study proteasome function and cancer therapeutics.

Bioactivity

• Target IC50:
  20S proteasome:0.93 nM(Ki)|20S proteasome:3.4 nM
• In Vivo:
  Upon contact with aqueous solutions and plasma, MLN9708 rapidly hydrolyzes into MLN2238, which possesses bioactivity. MLN2238 inhibits the chymotrypsin-like hydrolytic sites of the 20S proteasome ([IC50=3.4 nM,Ki=0.93 nM]). It also inhibits the caspase-like ([IC50=31 nM]) and trypsin-like hydrolytic sites ([IC50=3.5 μM]) of the 20S proteasome.

• In Vitro:
  MLN9708 exhibits anticancer activity in a variety of solid tumors and hematologic malignancies.
• Cell Research:
  Calu-6 cells are cultured in MEM containing 10% FBS and 1% penicillin/streptomycin and plated 1 day before the start of the experiment at 1 × 104 cells per well in a 384-well plate. For IC50 determinations, cells are treated with varying concentrations of Bortezomib or MLN2238 in DMSO (0.5% final, v/v) for 1 hour at 37 °C. For reversibility experiments, cells are treated with either 1 μM Bortezomib or MLN2238 for 30 minutes at 37 °C and then washed thrice in medium to remove the Bortezomib or MLN2238. Cells are incubated for an additional 4 hours at 37 °C, after which the medium is removed and replaced with fresh medium. (Only for Reference)
