SIRT-IN-1 is primarily used in research settings to study the role of sirtuins, a family of proteins involved in regulating cellular processes such as aging, metabolism, and stress response. It is specifically employed as an inhibitor of SIRT1, SIRT2, and SIRT3, helping scientists understand the biological functions and therapeutic potential of these enzymes. In cancer research, SIRT-IN-1 is utilized to explore its effects on tumor growth and cellular survival, as sirtuins are often implicated in cancer progression. Additionally, it aids in investigating metabolic disorders and neurodegenerative diseases, where sirtuin activity plays a critical role. Its application is crucial for developing targeted therapies and advancing knowledge in cellular biology and disease mechanisms.
