SIRT-IN-2 is a selective inhibitor of SIRT2, a member of the sirtuin family of proteins involved in regulating cellular processes such as aging, metabolism, stress response, mitosis, and neurodegeneration. It is primarily used in research settings to study the role of SIRT2 and its inhibition in biological pathways. This compound helps scientists understand the functions associated with SIRT2 and is particularly valuable in exploring potential therapeutic strategies for age-related diseases, metabolic disorders, cancer, and neurological conditions like Parkinson's disease. Its application extends to preclinical studies aimed at developing drugs that modulate SIRT2 activity for improved health outcomes.
