BAY1125976 is primarily used in the field of cancer research and treatment. It functions as a selective inhibitor of certain enzymes involved in cell signaling pathways, particularly those that drive tumor growth and survival. By targeting these pathways, it helps in slowing down or stopping the proliferation of cancer cells. This compound is often utilized in preclinical studies to understand its efficacy and mechanism of action in various types of cancers. Additionally, it is investigated for its potential to enhance the effectiveness of existing cancer therapies when used in combination. Researchers also explore its role in overcoming resistance to conventional treatments, making it a valuable tool in the development of new therapeutic strategies.
