SIRT-IN-2 is primarily used in research settings to study the role of sirtuins, a class of proteins involved in regulating cellular processes such as aging, metabolism, and stress response. By inhibiting sirtuin activity, it helps scientists understand the biological functions and pathways associated with these proteins. This compound is particularly valuable in exploring potential therapeutic strategies for age-related diseases, metabolic disorders, and cancer. Its application extends to preclinical studies aimed at developing drugs that modulate sirtuin activity for improved health outcomes.
