Used in research for treating various cancers, particularly solid tumors such as breast, lung, and ovarian cancers. It acts as a potent inhibitor of multiple tyrosine kinases, including EGFR, HER2, and HER3, which are involved in cancer cell growth and survival. By blocking these signaling pathways, it helps suppress tumor proliferation and induce apoptosis. Investigated in clinical trials to evaluate its efficacy and safety, especially in patients with advanced or treatment-resistant cancers. Its multi-targeted approach makes it a candidate for overcoming resistance seen with single-target therapies.
