WZ8040 is primarily used in research settings to study its effects on cancer cells, particularly in cases of non-small cell lung cancer (NSCLC). It is known to inhibit specific kinases involved in tumor growth, making it a potential candidate for targeted cancer therapies. Researchers utilize WZ8040 to investigate its ability to block signaling pathways that promote cancer cell survival and proliferation. Additionally, it is explored for its potential to overcome resistance to other cancer treatments, offering a promising avenue for developing more effective therapeutic strategies. Its application is largely confined to preclinical studies, where it helps in understanding the molecular mechanisms of cancer and evaluating its efficacy in combination with other drugs.
