Seco Rapamycin sodium salt is primarily utilized in biomedical research due to its role as a derivative of rapamycin, a well-known immunosuppressant and mTOR inhibitor. It is often employed in studies focusing on cell signaling pathways, particularly those involving mTOR, to understand cellular processes like growth, proliferation, and autophagy. Researchers use it to explore its potential in cancer therapy, as inhibiting mTOR can suppress tumor growth. Additionally, it is investigated for its applications in neurodegenerative diseases, where modulating autophagy may help clear toxic protein aggregates. Its sodium salt form enhances solubility, making it more suitable for in vitro and in vivo experiments.
