TH5487 is a potent 8-oxoguanine DNA glycosylase 1 (OGG1) inhibitor with an IC50 of 342 nM. TH5487 stops OGG1 from recognizing its DNA substrate, inhibits DNA repair and modifies OGG1 chromatin dynamics, which results in the inhibition of proinflammatory pathway genes.

    TH5487 purchased from MedChemExpress. Usage Cited in: Cell Prolif. 2023 Feb 14;e13418.  [Abstract]

    Th5487 ameliorates renal Renal ischemia-reperfusion injury. Th5487 (30 mg/kg; i.p.; every day for 3 days before the schemia-reperfusion (IR) operation) treatment group shows partial tubular dilation and vacuolar degeneration after IR24h, with a reduced tubular injury score. In comparison, nuclear pyknosis and necrosis of renal tubules are observed in the vehicle group after IR24h (Figure D, E).

    Description

    TH5487 is a potent 8-oxoguanine DNA glycosylase 1 (OGG1) inhibitor with an IC50 of 342 nM. TH5487 stops OGG1 from recognizing its DNA substrate, inhibits DNA repair and modifies OGG1 chromatin dynamics, which results in the inhibition of proinflammatory pathway genes[1].

    In Vitro

    TH5487 (5 μM; 1 hour) decreases TNFα- and LPS-induced proinflammatory gene expression to near pretreatment levels[1].
    ? TH5487 (0-10 μM; 1 hour) perturbs binding of NF-κB to 8-oxoG–containing synthetic DNA in nuclear extracts from MLE 12 or hSAEC cells[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: ≥ 2.08 mg/mL (3.84 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

    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.
