Pt(IV) compounds include a mitochondria targeting moiety. One example of a Pt(IV) compound having a mitochondria targeting moiety is a Pt(IV) cisplatin-based compound. Upon reduction, the mitochondrial targeting moieties are released resulting in a Pt(II) therapeutic agent. Pt(IV) compounds including a mitochondria targeting moiety can be included in nanoparticles. The compounds or nanoparticles can be used to treat, for example, cancer.
