Used as a potent inhibitor in targeted cancer therapies, particularly in the treatment of certain leukemias and solid tumors. It functions by selectively inhibiting specific tyrosine kinases involved in cell proliferation and survival pathways. Its structure allows for high binding affinity to mutant forms of kinase targets, making it effective in resistant cancer cases. Commonly employed in research and development of oral oncology drugs due to its favorable pharmacokinetic profile and ability to cross cellular membranes efficiently.
