mTOR inhibitor-1 is primarily used in research to study the mTOR signaling pathway, which plays a critical role in cell growth, proliferation, and survival. It is employed in preclinical studies to investigate the effects of mTOR inhibition in various diseases, particularly cancer, where dysregulated mTOR signaling is often observed. Researchers use this compound to explore potential therapeutic strategies for inhibiting tumor growth and metastasis. Additionally, it is utilized in studies related to aging, metabolic disorders, and immune regulation, as mTOR signaling is implicated in these processes. Its application helps in understanding the molecular mechanisms underlying these conditions and in developing targeted therapies.
