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].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
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.
