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 is applied in cellular assays to suppress ERK activity, helping scientists investigate cell proliferation, differentiation, and apoptosis mechanisms. Commonly used in cancer research, it aids in evaluating the impact of ERK pathway inhibition on tumor growth and survival. Also utilized in inflammation and neurodegenerative disease studies to assess potential therapeutic strategies by modulating kinase activity. Its application is limited to in vitro and preclinical models due to lack of clinical approval.
