Used primarily in biomedical research to inhibit the MEK1/2 signaling pathway, enabling studies on cell proliferation, differentiation, and apoptosis. Commonly applied in cancer research to assess tumor growth suppression and evaluate potential therapeutic strategies. Also utilized in neuroscience to investigate synaptic plasticity and memory formation mechanisms. Effective in both in vitro and in vivo models, supporting its role in pathway-specific modulation with high selectivity.
