Product Introduction

MI-2 (MALT1 inhibitor) is an irreversible MALT1 inhibitor.
In vitro
Daily intraperitoneal injection of 25 mg/kg MI-2 effectively inhibits the growth of TMD8 and HBL-1 ABC-DLBCL xenografts, while it has no effect on the growth of OCI-Ly1 tumors.
In vivo
MI-2 demonstrates excellent cellular permeability and inhibits the function of MALT1 in the ABC-DLBCL cell lines. It selectively inhibits the growth of MALT1-dependent cell lines, with GI50 values of 0.2, 0.5, 0.4, and 0.4 μM in HBL-1, TMD8, OCI-Ly3, and OCI-Ly10 cells, respectively. Conversely, ABC-DLBCL cell lines not dependent on MALT1, such as U2932 and HLY-1, along with two types of GCB-DLBCL cell lines, exhibit resistance to MI-2.
Kinase Assay
High-Throughput Screening for MALT1 Proteolytic Activity Inhibitors: Ac-LRSR-AMC is used as substrate and reactions are measured with excitation/emission wavelengths of 360/465 nm. Two time points are measured for each reaction to eliminate false positives due to compound autofluorescence. The final percent inhibition is calculated with the formula {[fluorescencetest compound (T2-T1)-fluorescenceneg ctrl (T2-T1)]/[fluorescencepos ctrl (T2-T1)-fluorescenceneg ctrl (T2-T1)]} × 100, where Z-VRPR-FMK (300 nM) is used as positive control and buffer only as negative control. The positive hits are validated in concentration-response experiments within a dose range of 0.122–62.5 μM to determine IC50 of the compounds. Activity is validated using recombinant full-length wild-type MALT1.
Cell Research
Cell proliferation is determined by ATP quantification using a luminescent method and trypan blue dye exclusion. Standard curves for each cell line are calculated by plotting the cell number (determined using trypan blue) against their luminescence values, and cell number is calculated accordingly. Cell viability in drug-treated cells is normalized to their respective controls (fractional viability), and results are given as 1-fractional viability. CompuSyn software is used to determine GI25 and GI50 values.(Only for Reference)

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg, each TargetMol | Animal experiments animal weighs 20 g, and the dosage volume is 100 μL. A total of TargetMol | Animal experiments 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL.
Mother liquor preparation method: 2 mg of drug dissolved in 50 μLDMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μLDMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μLTween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify.
