    ITD-1 purchased from MedChemExpress. Usage Cited in: Oncotarget. 2017 Dec 14;9(3):3188-3197.  [Abstract]

    Treatment with 5 μM ITD-1, DMSO, and blank, respectively, for 24 h under 1% O2 condition. ITD-1 inhibits the phosphorylation of Smad2/3 by inhibiting TβRII. Meanwhile, HIF-1α and Smad2/3 levels remain stable in all three groups. The histogram shows the protein band intensity ratio of p-Smad2 to Smad2 and p-Smad3 to Smad3.

    Description

    ITD-1 is the first selective TGFβ receptor inhibitor with an IC50 of 460 nM.

    IC50 & Target

    IC50: 460 nM (TGFβ receptor)
    In Vitro

    ITD-1 potently blocks phosphorylation of the effector SMAD2/3 proteins induced by TGFβ2, and only minimally in response to Activin A. HEK293T cells are transfected with a Smad4 response element driving luciferase (SBE4-Luc) to test whether ITD-1 blocks Activin A/Nodal and/or TGFβ signaling, which utilize the same intracellular signaling cascade through Smad4. ITD-1 strongly inhibits TGFβ2 signaling with similar efficacy (92% vs. 99% respectively), but with lower potency compared to SB-431542, an ACVR1B/TGFBR1 kinase inhibitor (IC50= 850nM vs. 70nM respectively), and is a weak and partial inhibitor of Activin A signals. ITD-1 selectively enhances the differentiation of uncommitted mesoderm to cardiomyocytes, but not to vascular smooth muscle and endothelial cells. ITD-1 reveals an unexpected role for TGFβ signaling in controlling cardiomyocyte differentiation from multipotent cardiovascular precursors[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

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

      Solubility: ≥ 2.5 mg/mL (6.02 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.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 2.5 mg/mL (6.02 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    Cell Assay

    For the Smad4-Response element (SBE4) assay, 293T cells are grown in Phenol Free DMEM-high glucose supplemented with 1% FBS. About 30000 cells/cm2 are reverse transfected onto white 384-well cell-culture plates with 10ng of SBE4-Lux and CMV-Renilla-Lux using Lipofectamine 2000. Cells are allowed to adhere for at least 12 hours and induced with either TGFβ2 (15 ng/mL), Activin A (15 ng/mL). Simultaneously, ITD-1 (0.001, 0.01, 0.1, 1, and 10 μM) is added to cells. SB-431542 is used as a positive control for Activin A/TGFβ-signaling inhibition. To determine luminescence levels, Dual-Glo kit is used and measured on an Envision plate reader. Firefly luminescence is normalized against renilla luciferase.

    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.
