Used primarily in cancer research, it functions as a MEK inhibitor, targeting the MAPK/ERK pathway to inhibit tumor growth. It is studied for its potential in treating various cancers, including melanoma and colorectal cancer, by disrupting signaling pathways that promote cancer cell proliferation. Additionally, it is explored in combination therapies to enhance the efficacy of other anticancer drugs. Its role in preclinical and clinical trials highlights its significance in developing targeted cancer treatments.
