TAK-243 (MLN7243) is a first-in-class, selective ubiquitin activating enzyme, UAE (UBA1) inhibitor (IC50=1 nM), which blocks ubiquitin conjugation, disrupting monoubiquitin signaling as well as global protein ubiquitination. TAK-243 (MLN7243) induces endoplasmic reticulum (ER) stress, abrogates NF-κB pathway activation and promotes apoptosis.

    Left: immunoblot analysis assessing JAK1 expression in Myc-CaP cells that received knockout of Jak1 (Jak1 KO). Cells receiving nontargeting sgRNA were used as control. Right: surface expression of MHC-I measured by flow cytometry in the indicated cells treated with or without 50 nmol/L TAK-243 and stimulated with or without IFN-γ. Data were acquired from technical triplicates, representative of two independent experiments.

    The E1 inhibitor decreased the flux of ER-phagy in mCherry-GFP-FAM134B-WT cells induced with Torin 1. ER-phagy flux was quantified as the ratio between mCherry+/GFP– and mCherry+/GFP+ puncta, quantified using CQ1 software. Data are means ± s.d. of n = 5 independent experiments in which the number of cells per condition were: (DMSO) 837 basal, 1072 BafA1, 1038 Torin1, 966 BafA1+Torin1. Number of cells (10 µM TAK243): 729 basal, 1174 BafA1, 1060 Torin1, 1121 Torin1+BafA1

    Cells were treated with DMSO (control) or 10 µM TAK243 for 1, 2 and 4 h before TUBE-2 pulldown assays. Endogenous ubiquitination of FAM134B was detected by western blot (n = 1 experiment). The results showed that TAK243, a potent inhibitor of the ubiquitin (Ub)-activating enzyme, abolished endogenous FAM134B ubiquitination.

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.08 mg/mL (4.00 mM); Clear solution

    Normal keratinocytes (normal human keratinocytes (NHK) and recessive dystrophic epidermolysis bullosa keratinocytes (RDEBK)) and cSCC cell lines are seeded into 96 well plates and live cell number and cell death are analysed with an IncuCyte ZOOM real-time imager using the CellTox Green Cytotoxicity Assay. Relative EC50 values are determined using GraphPad Prism. For clonogenic assays cells are seeded into six well plates. Inhibitors (e.g., TAK-243; 0.01, 0.1, 1, and 10 μM) are added for the indicated times and then cells are maintained in drug-free medium for up to 2 weeks to allow colony formation. Colonies are fixed in 10% methanol, 10% acetic acid and stained with crystal violet[1].

    Mice[2]
    The preclinical efficacy and toxicity of TAK-243 are assessed in mouse models of AML. OCI-AML2 cells are injected subcutaneously (sc) into SCID mice, and when tumors are palpable, mice are treated with TAK-243 (20 mg/kg sc twice weekly). As an additional model, primary AML cells from 2 patients are injected into the femurs of NOD-SCID mice. Two weeks after injection, mice are treated with TAK-243 (20 mg/kg sc twice weekly). After 3 weeks of treatment, mice ae sacrificed, and AML engraftment in the non-injected femur is measured by flow cytometry[2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
