Ixazomib Citrate (MLN9708) immediately hydrolyzed to Ixazomib (MLN2238), the biologically active form, on exposure to aqueous solutions or plasma. Ixazomib (MLN2238) inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome with IC50/Ki of 3.4 nM/0.93 nM in cell-free assays, less potent to β1 and little activity to β2. Ixazomib (MLN2238) induces autophagy. Phase 3.

MLN9708 is a selective, orally bioavailable, second-generation proteasome inhibitor. MLN9708 has a shorter proteasome dissociation half-life and improved pharmacokinetics, pharmacodynamics, and antitumor activity compared with bortezomib, which we believe plays an important role in its improved tissue distribution. MLN9708 has a larger blood volume distribution at steady state, and analysis of 20S proteasome inhibition and markers of the unfolded protein response confirms that MLN9708 has greater pharmacodynamic effects in tissues than bortezomib. MLN9708 is a second-generation small-molecule proteasome inhibitor being developed for the treatment of a broad range of human malignancies. [1] Upon exposure to aqueous solutions or plasma, MLN9708 rapidly hydrolyzes to its biologically active form MLN2238. [2] MLN2238 is the biologically active form of MLN9708. [3] |

In vivo | MLN9708 shows superior antitumor activity in both solid tumor and hematologic preclinical xenograft models when administered via multiple dosing routes and regimens. [1] Recent preclinical pharmacology studies shows that MLN9708 has a shorter proteasome dissociation half-life than bortezomib, as well as improved pharmacokinetics, pharmacodynamics, and antitumor activity in xenograft models [2] MLN9708 has shown antitumor efficacy in a wide range of tumor xenografts.

Protocol
Kinase Assay:[1] |
- Collapse
Kinase assay: Calu-6 cells are cultured in MEM containing 10% fetal bovine serum 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. Proteasome activity is assessed by monitoring hydrolysis of the chymotrypsin-like substrate Suc-LLVY-aminoluciferin in the presence of luciferase using the Proteasome-Glo assay reagents according to the manufacturer's instructions. Luminescence is measured using a LEADseeker instrument. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
