Tunlametinib
Based on 1 Customer Validation
Tunlametinib is a highly selective, orally active MEK1/2 inhibitor (IC50=1.9 nM, MEK1). Tunlametinib blocks the RAS-RAF-MEK-ERK signaling pathway, arrests tumor cell cycle and promotes apoptosis. Tunlametinib potently inhibits the proliferation of RAS/RAF mutant cancer cells (such as BRAF V600E, KRAS G12C mutant cells). Tunlametinib shows synergistic anti-tumor effects with BRAF/KRASG12C/SHP2 inhibitors, Docetaxel (HY-B0011). Tunlametinib can be used to study targeted therapy for RAS/RAF mutation-driven malignancies (such as melanoma, colorectal cancer, and non-small cell lung cancer).

Tunlametinib inhibits the cell viability of BRAF/KRAS mutant cell lines: A375, Colo-829, HL-60 melanoma cells, COLO 205, HT-29 colon cancer cells, Calu-6, A549 lung cancer cells, with IC50 of 0.86 nM, 3.46 nM, 0.67 nM, 0.94 nM, 10.07 nM, 59.89 nM, respectively. Tunlametinib has no significant effect on RAS/RAF wild-type cells (H1975, MRC-5)[1].
Tunlametinib (1-9 nM; 48 h) dose-dependently increases the proportion of A375 cells in the G0/G1 phase and induces cell cycle arrest[1].
Tunlametinib (10-90 nM or 1-9 nM; 48 h) dose-dependently induces apoptosis in COLO 205 cells (10-90 nM), without significant induction effect on A375 cells (1-9 nM)[1].
Tunlametinib (0.1-100 nM; 48 h) dose-dependently reduces the level of phosphorylated ERK (p-ERK) in A375 cells with an IC50 of approximately 1.16 nM. Tunlametinib completely inhibits ERK phosphorylation at a concentration of 100 nM[1].
