Description
CMS-121 is a small-molecule fisetin derivative studied for its activity as a fatty acid synthase (FASN) and acetyl-CoA carboxylase 1 (ACC1) inhibitor. In research models, it is investigated for reducing lipid peroxidation, modulating brain lipid metabolism, and protecting against oxytotic/ferroptotic cell death. Originally developed at the Salk Institute as a candidate for Alzheimer’s disease and age-related cognitive decline, CMS-121 has also been examined in the literature for its effects on diet-induced obesity, type 2 diabetes models, kidney function, and overall geroprotection.
