The lignan manassantin is a potent and specific inhibitor of mitochondrial complex I and bioenergetic activity in mammals.

ABSTRACT: Dineolignans manassantin A and B from the plant Saururus cernuus are used in traditional medicine to manage a wide range of ailments such as edema, jaundice, and gonorrhea. Cell-based studies have identified several molecular target candidates of manassantin including NF-κB, MAPK, STAT3, and hypoxia-inducible factor 1α (HIF-1α). It is unclear whether or how these structurally diverse proteins or pathways mediate any of the medical benefits of manassantin in vivo Moreover, it has recently been reported that manassantin causes developmental arrest in zebrafish by inhibiting the mitochondrial complex I, but it is unknown whether manassantin inhibits mitochondrial respiration in intact mammalian cells and live animals. Here, we present direct evidence that manassantin potently an
