DS03090629 is an orally active MEK inhibitor that inhibits MEK activity in an ATP-competitive manner. DS03090629 exhibits high affinity for both MEK and phosphorylated MEK, with Kd values of 0.11 and 0.15 nM, respectively. It effectively inhibits the proliferation of BRAF-mutant overexpressing melanoma cell lines, with IC50 values of 74.3 and 97.8 nM for BRAF V600E and MEK1 F53L transfected A375 cells, respectively. DS03090629 holds potential value in the field of anti-melanoma therapy[1].
