TETi76 is an orally active TET family inhibitor with IC50 values ??of 1.5, 9.4 and 8.8 μM for TET1, TET2 and TET3, respectively. TETi76 competitively binds to the active site of TET enzymes, reduces cytosine hydroxymethylation and restricts clonal growth of TET2 mutants in vitro and in vivo, but does not affect the growth of normal hematopoietic precursor cells. TETi76 can be used for leukemia research.

TETi76 competitively binds to the active site of TET enzymes, reduces cytosine hydroxymethylation and restricts clonal growth of TET2 mutants in vitro and in vivo, but does not affect the growth of normal hematopoietic precursor cells.

    TET1

    In Vitro

    TETi76 (25 μM; 3 d) induces cell death and inhibits TET dioxygenase activity in SIG-M5 cells[1]. TETi76 (20-37 μM; 12 h) reduces intracellular 5 hmC content in a dose-dependent manner in various human leukemia cell lines (K562, MEG-01, SIG-M5, OCI-AML5, and MOLM13), with the concentration range of 50% inhibition of 5 hmC being 20-37 μM[1].
    TETi76 (25 μM; 24 h) mimicks the expression signature caused by TET2 deficiency in gene expression analysis of K562? (TET2 (+/+) and TET2 (-/-) cells, and addition of ascorbic acid, known to enhance TET activity, counteracts the changes induced by TETi76[1].

    In Vivo

    TETi76 (50 mg/kg; oral; 5 days per week; 3 months) has no significant effect on the total body weight and overall blood cell counts of mice in Tet2+/+, Tet2+/-, and Tet2-/- mouse models on the C57BL6 background, but reduces the spleen size of Tet2-deficient mice in a gene dose-dependent manner[1].
    TETi76 (25 mg/kg; ip; once daily, 5 days per week; 4 weeks) limits the proliferative advantage of Tet2?/? (CD45.2) cells in the C57BL6 CD45.1 Pep Boy mouse model (lethally irradiated and transplanted with mixed bone marrow cells) without affecting the proportion of mice receiving Tet2+/+ (CD45.2) cells[1].
    TETi76 (50 mg/kg; oral) significantly reduces tumor burden in the immunodeficient NSG mouse model (subcutaneously implanted with the human TET2?/? leukemia cell line SIG-M5)[1]).

    In Vivo:

    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

      Solubility: ≥ 2.5 mg/mL (11.56 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

      Solubility: ≥ 2.5 mg/mL (11.56 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    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.
