DS03090629
Based on 1 Customer Validation
DS03090629 is an orally active, ATP-competitive MEK1/2 inhibitor. DS03090629 binds to the ATP-binding pocket of MEK, and this binding is unaffected by phosphorylation status. DS03090629 exhibits high affinity for both MEK and phosphorylated MEK, with Kd values of 0.11 nM and 0.15 nM, respectively. DS03090629 inhibits the MEK1F53L mutant while retaining activity relative to wild-type MEK1. DS03090629 suppresses the MAPK pathway, cell proliferation, and BRAF overexpression-mediated drug resistance in melanoma cells. DS03090629 can be used for research related to melanoma.

DS03090629 (0.5 mM; 48 h) binds to the ATP-binding pocket of human MEK1 (residues 37-383 with MEK1S298N, MEK1S299K, MEK1Y300K mutations) as visualized via X-ray crystallography[1].
DS03090629 (1-10000 nM; 60 min) potently inhibits kinase activity of both wild-type phosphorylated MEK1 and phosphorylated MEK1F53L mutant in a cell-free assay[1].
DS03090629 (0.001-10000 nM) potently inhibits both non-phosphorylated and phosphorylated MEK1 kinase activity in in vitro assays, with minimal difference in efficacy between the two protein forms[1].
DS03090629 (3.2-2000 nM) maintains high binding affinity for both non-phosphorylated and phosphorylated human MEK1, with a KD of 0.1086 nM for npMEK1 and 0.1497 nM for pMEK1[1].
DS03090629 (350 nM) exhibits high selectivity for MEK1/2 over a panel of 159 other kinases when tested at 350 nM in the presence of 1 mM ATP[1].
DS03090629 (0.1-10000 nM; 2 h) inhibits ERK phosphorylation with IC50 values of 37.1 nM in A375_mock cells, 74.3 nM in BRAF-overexpressing A375_BRAF cells, and 95.3 nM in HUVEC cells, with minimal potency reduction in the resistant cell line[1].
DS03090629 (0.1-10000 nM; 3 day) inhibits cell proliferation with IC50 values of 60.7 nM in A375_mock cells, 165 nM in BRAF-overexpressing A375_BRAF cells, and 556 nM in HUVEC cells, with minimal potency reduction in the resistant cell line[1].
DS03090629 (0.1-10000 nM; 2 h) inhibits ERK phosphorylation in MEK1F53L-expressing A375_MEK cells with an IC50 of 97.8 nM, with minimal potency reduction relative to parental A375_mock cells[1].
DS03090629 (0.1-10000 nM 3 day) inhibits cell proliferation in MEK1F53L-expressing A375_MEK cells with an IC50 of 165 nM, with minimal potency reduction relative to parental A375_mock cells[1].
DS03090629 (0.1-10000 nM; 2 h) retains relatively potent ERK phosphorylation inhibitory activity in NRASQ61K-expressing A375_NRAS cells compared to other tested inhibitors[1].
