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.

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].

Stock Solution Working Solution

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.

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.

Protocol 3

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

Solubility: ≥ 2.08 mg/mL (6.26 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 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 (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
