LUT014
Based on 1 Customer Validation
LUT014 is a topical inhibitor targeting BRAF that cannot pass through the blood-brain barrier. LUT014 inhibits BRAF kinase and abnormally activates the MAPK/ERK signaling pathway, promoting the proliferation of epidermal keratinocytes, repairing skin barrier damage caused by radiation damage, and alleviating inflammatory responses. LUT014 is independent of RAS signaling and accelerates the repair and regeneration of damaged skin cells. LUT014 can be used to study radiation dermatitis, especially skin damage caused by breast cancer radiotherapy.

Biological Activity
|
B-Raf 11.7 nM (IC50) |
LUT014 (0.3 μM; 2 h) induces elevated levels of phosphorylated ERK1/2 (pERK) in primary human epidermal keratinocytes (HEKa), reverses pERK inhibition induced by Erlotinib (HY-50896) or Cetuximab (HY-P9905), and restores MAPK signaling to levels close to those stimulated by growth factors[4].
LUT014 (0.002-1.11 μM; 72 h) induces a bell-shaped proliferation curve in KRAS G12C mutant MIA-PaCa-2 pancreatic cancer cells in a concentration-dependent manner, with the strongest proliferation at 0.041 μM, and high concentrations (≥0.37 μmol/L) inhibited proliferation[4].

-
Cell Line:Primary human epidermal keratinocytes (HEKa cells)
-
Concentration:0.3 μM
-
Incubation Time:2 h
-
Result:Increased the pERK/total ERK2 ratio by 1.8-fold compared to vehicle control (DMSO), reversing the 50% reduction in pERK induced by Erlotinib (10 μM) or Cetuximab (50 μg/mL).
The combination of LUT014 with EGFR inhibitors restored pERK levels to 85% of those stimulated by human keratinocyte growth supplement (HKGS).
-
Cell Line:MIA-PaCa-2 (KRAS G12C-mutated pancreatic cancer cells)
-
Concentration:0.002, 0.05, 0.14, 0.41, 1.11 μM
-
Incubation Time:72 h
-
Result:Significantly enhanced cell proliferation by 40% compared to vehicle control, at 0.041 μM, while concentrations ≥0.37 μmol/L caused growth arrest.
The maximal proliferation at low doses correlated with paradoxical MAPK activation, as demonstrated by increased pERK levels in Western blot analyses.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (3.94 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.
