ME-344 is a synthetic metabolite of NV-128, a potent inhibitor of mitochondrial oxidative phosphorylation (OXPHOS) complex I, disrupting ATP generation and oxygen consumption. It also inhibits mTOR by downregulating the AKT/mTOR pathway, exhibiting anticancer activity by inhibiting cell growth and viability in leukemia cell lines with IC50 values of 70–260 nM.
