Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	3.600mg/ml (9.97mM)	Taking the 1 mL working solution as an example, add 50 μL of 72 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.900mg/ml (2.49mM)	Taking the 1 mL working solution as an example, add 50 μL of 18 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Ixazomib (MLN2238) inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome with IC50 and K_i of 3.4 nM and 0.93 nM in cell-free assays, respectively, also inhibits the caspase-like (β1) and trypsin-like (β2) proteolytic sites, with IC50 of 31 and 3500 nM. Ixazomib (MLN2238) induces autophagy. Phase 3.
in vitro	At higher concentrations, this compound also inhibits the caspase-like (β1) and trypsin-like (β2) proteolytic sites with IC50 of 31nM and 3.5uM, respectively. It inhibits Calu-6 cell with IC50 of 9.7 nM. MLN2238 is a selective, potent, and reversible inhibitor of the proteasome in tumor cells. This compound shows time-dependent reversible proteasome inhibition. Both this compound and Bortezomib shows time-dependent reversible proteasome inhibition; however, the proteasome dissociation half-life for it is determined to be ∼6-fold faster than that of Bortezomib (18 and 110 minutes, respectively). It dissociates more rapidly from the proteasome than Bortezomib, consistent with faster recovery of proteasome activity observed in the Proteasome-Glo assay. It has a greater overall tumor pharmacodynamic effect than Bortezomib as assessed by 20S inhibition. ^[1]This compound is the biologically active form of MLN9708. ^[2]
in vivo	MLN2238 induces a greater pharmacodynamic response than Bortezomib in xenograft tumors. This compound shows greater maximum and sustained tumor proteasome inhibition compared with Bortezomib in xenograft models. These results confirm that the improved tumor exposure seen with this agent translates into an improved tumor pharmacodynamic response both at the level of and downstream from the proteasome. It shows antitumor activity in the CWR22 xenograft model. This chemical shows greater tumor pharmacodynamic responses in WSU-DLCL2 xenografts compared with Bortezomib. Similarly, Bortezomib treatment only led to a minor increase in GADD34 levels in WSU-DLCL2 xenograft tumors, whereas it strongly induces its expression. ^[1] This compound has an improved pharmacodynamic profile and antitumor activity compared with Bortezomib in both OCI-Ly10 and PHTX22L models. ^[2]
特徴	A first-in-class proteasome inhibitor that has improved pharmacokinetics (PK), pharmacodynamics(PD), and antitumor activity in preclinical studies.

キナーゼアッセイ	Kinase assay
キナーゼアッセイ	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.
細胞アッセイ	細胞株	Calu-6 cells
	濃度	~10 nM
	反応時間	1 hour or 30 minutes
	実験の流れ	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 this compound 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 this chemical for 30 minutes at 37 °C and then washed thrice in medium to remove the Bortezomib or this agent. Cells are incubated for an additional 4 hours at 37 °C, after which the medium is removed and replaced with fresh medium.
