WAY-600 is a selective inhibitor of the mTOR kinase (Mechanistic Target of Rapamycin), primarily utilized in research settings to study its effects on cellular signaling pathways involved in cell growth, metabolism, and autophagy. It modulates biological processes such as cell proliferation and differentiation by targeting dysregulated mTOR pathways. Researchers employ WAY-600 to investigate its potential in diseases including certain cancers, inflammatory conditions, and neurological disorders. Its application is largely confined to preclinical studies, serving as a tool to understand molecular mechanisms and identify therapeutic targets.
