Dear Editor,Atovaquone(ATO),a mitochondrial inhibitor,has anti-cancer effects[1].Based on ATO,we developed mitochondria-targeted atovaquone(Mito-ATO)that had even stronger anti-tumor efficacy than ATO[2].We syn-thesized Mito-ATO by attaching the bulky triphenylphos-phonium(TPP)group to ATO via a ten-carbon alkyl chain(Supplementary file of methods;Supplementary Figure S1).
