Biological Activity
|
ACSL4 |
LIBX-A403 inhibits hACSL4 with an IC50 of 0.049 μM and a Kd of 0.29 μM and no activity against ACSL3 at concentrations up to 50 μM[1].
LIBX-A403 (18 h pretreatment) potently inhibits RSL3 (HY-100218A)-induced ferroptosis in MDA-MB-231 cells with an EC50 of 172 nM and no cytotoxicity up to 25 μM[1].
LIBX-A403 (10 μM; 2 h) engages with endogenous ACSL4 in MDA-MB-231 cells, as confirmed by increased thermal stability of the protein[1].
LIBX-A403 (2.5 μM; 4 h pretreatment) significantly inhibits Arachidonic acid (HY-109590) + Fe-induced ferroptosis and reduces lipid peroxidation in LUHMES dopaminergic neurons[1].

-
Cell Line:MDA-MB-231 human breast cancer cell
-
Concentration:10 μM
-
Incubation Time:2 h
-
Result:Increased the thermal stability of ACSL4, as evidenced by higher levels of soluble ACSL4 protein at elevated temperatures compared to DMSO-treated controls.
-
Cell Line:LUHMES human dopaminergic neuron
-
Concentration:2.5 μM
-
Incubation Time:4 h (pretreatment); 48 h (AA+Fe exposure)
-
Result:Significantly protected LUHMES cells from AA+Fe-induced ferroptosis, with a marked reduction in lipid peroxidation compared to untreated ferroptosis-induced cells.
Showed protection comparable to that achieved with ACSL4 siRNA.

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.
