ERK1/2 inhibitor 1 is a potent, orally bioavailable ERK1/2 inhibitor, showing 60% inhibition at 1 nM and an IC50 of 3.0 nM against ERK1 and ERK2, respectively[1].
ERK1/2 inhibitor 1 (Compound 27) shows excellent antiproliferative potency with IC50s of 4.9 and 7.5 nM in A375 and Colo205 cells, respectively[1].
