FEN1-IN-1 (compound 1) is a small molecule flap endonuclease 1 (FEN1) inhibitor with antitumor activity. FEN1-IN-1 binds to the active site of FEN1 and partly achieves inhibition by the co-ordination of Mg2+ ions. FEN1-IN-1 initiaties a DNA damage response and activates the ATM checkpoint signalling pathway, the phosphorylation of histone H2AX and the ubiquitination of FANCD2 in mammalian cells. FEN1-IN-1 is promising for research of cancers.

Description

FEN1-IN-1 (compound 1) is a small molecule flap endonuclease 1 (FEN1) inhibitor with antitumor activity. FEN1-IN-1 binds to the active site of FEN1 and partly achieves inhibition by the co-ordination of Mg2+ ions. FEN1-IN-1 initiaties a DNA damage response and activates the ATM checkpoint signalling pathway, the phosphorylation of histone H2AX and the ubiquitination of FANCD2 in mammalian cells. FEN1-IN-1 is promising for research of cancers[1].

IC50 & Target

FEN1[1]
In Vitro

FEN1-IN-1 (0-30 μM, 3 days) inhibits 212 cell-lines growth with a mean GI 50 of 15.5 μM[1].
FEN1-IN-1 (0.2-20 μM, 24 h) induces Hela cells disrupted for MRE11A more sensitive and decreasea the survival of the MRE11A deficient cell-lines due to cytotoxicity[1].
FEN1-IN-1 (0-10 μM, 24 h) inhibits both FEN1 and EXO1 function and induces a DNA damage response to activate the signalling pathways in SW620 and HCT-116 cells[1].
FEN1-IN-1 (10 μM, 24 h) leads to replication fork instabilities that, if left unrepaired, can lead to cell death[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 (6.26 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (6.26 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
