Torin 2 is primarily used in biomedical research as a potent and selective inhibitor of mTOR (mechanistic target of rapamycin), a key protein kinase involved in cell growth, proliferation, and survival. It is widely applied in studies related to cancer, as it effectively suppresses mTOR signaling in both mTORC1 and mTORC2 complexes, leading to reduced tumor cell growth and increased autophagy. Researchers also use Torin 2 to investigate cellular metabolism, aging, and the regulation of protein synthesis. Due to its ability to cross the blood-brain barrier, it has been explored in neurological disease models, including neurodegenerative disorders where mTOR dysregulation plays a role. Its high selectivity and potency make it a valuable tool compound in preclinical studies aimed at understanding mTOR pathway dynamics and evaluating potential therapeutic strategies.
