Used primarily as a selective inhibitor of ERK1 and ERK2 kinases in research settings, this compound plays a key role in studying the MAPK signaling pathway. It helps scientists investigate cell proliferation, differentiation, and apoptosis, particularly in cancer-related studies. Due to its ability to block ERK activity, it is applied in experiments exploring tumor growth and potential therapeutic interventions. Commonly used in vitro, it aids in validating ERK-dependent mechanisms and assessing the effects of pathway inhibition in various cell types.
