Description: RO5068760 , a substituted hydantoin, is a potent, highly selective, non-adenosine triphosphate (ATP)-competitive MEK1/2 inhibitors. RO5068760 shows significant efficacy in a broad spectrum of tumors with aberrant mitogen-activated protein kinase pathway activation. In vitro, RO5068760 demonstrates MEK1 kinase inhibitory activity with an IC50 of 0.025 μM in a cRaf/MEK/ERK cascade assay RO5068760 showed superior efficacy in tumors harboring B-RafV600E mutation.
