Summary	Atpenin A5 is a highly specific mitochondrial complex II inhibitor used in bioenergetics research.
Details	Atpenin A5 is a chlorinated fungal metabolite isolated from Penicillium species. It is a potent and specific inhibitor of mitochondrial complex II (succinate-ubiquinone oxidoreductase), binding to the quinone-binding pocket of succinate dehydrogenase. Atpenin A5 is widely used as a biochemical tool to investigate electron transport chain function, mitochondrial bioenergetics, reactive oxygen species production, and metabolic reprogramming in mammalian cells. It has also contributed to structural elucidation of the complex II quinone-binding site.
