| Mitochondria-targeted antioxidants | Bioactive component | Linker | Effects | Reference |
| MitoE | Vitamin E | 2-Carbon aliphatic linker | (1) Minimized lipid peroxidation and protected cells from oxidative damage (2) Eliminated H2O2-induced oxidative stress and caspase activation in cells (3) Accumulated in tissues (heart, brain, muscle, liver, and kidney) and protected tissues from oxidative damage | [28, 30] | Mito-vitamin E derivation | Vitamin E | 11-Alkyl linker | (1) Inhibited energy metabolism and promote cell death (2) Antitumor properties | [31, 32] | SkQ1 SkQR1 | Plastoquinone | 10-Alkyl linker | (1) Minimized lipid peroxidation and ROS-induced apoptosis (2) Beneficial roles in many diseases including aging, stroke, myocardial infarction, sarcopenia, dry eye syndrome, vascular inflammation | [33, 34] | MitoQ | Coenzyme Q | 10-Alkyl linker | (1) Penetrated the mitochondrial membrane and inhibited lipid peroxidation (2) Beneficial roles in animal models of alcoholic fatty liver, neurodegenerative diseases, ischemia-reperfusion, hypertension, sepsis, and kidney damage in type I diabetes | [35, 36] | MitoC MitoVitC11 | Vitamin C | Thioalkyl linker | (1) Prevented mitochondrial lipid peroxidation and protected mitochondrial aconitase (2) Scavenged O2–, peroxyl radicals, and Fe3+ and could be rapidly recycled to the active ascorbate moiety | [37] | MitoSOD | M40403 | Thioalkyl linker | (1) Regulated the mitochondrial redox system to convert ROS (2) Reversed the rapid and progressive inhibition of aconitase through redox cycling (3) Retained Mn2+ under nonacidic conditions | [38, 39] |
