SRT1720 is primarily used in biomedical research for its potential role in modulating cellular aging and metabolic processes. It activates SIRT1, a member of the sirtuin family of proteins linked to longevity and stress resistance. Due to this activation, it has been studied for its effects on improving insulin sensitivity, reducing inflammation, and protecting against age-related diseases such as type 2 diabetes, neurodegenerative disorders, and cardiovascular conditions. It is also investigated for its ability to mimic caloric restriction, a dietary regimen associated with extended lifespan in various organisms. SRT1720 serves as a tool compound in preclinical studies to explore the therapeutic potential of sirtuin activation, though it is not used clinically in humans.
