Catalase is an essential enzyme in the metabolism of H2O2 and reactive oxygen species (ROS). The expression and localization of Catalase are markedly altered in tumors.

Acetyl-L-carnitine hydrochloride (Acetyl L-carnitine hydrochloride) is a nutritional supplement composed of the hydrochloride salt form of the acetylated form of the endogenously produced L-carnitine, with potential neuroprotective, cognitive-enhancing, anti-depressive and immunomodulating activities. It may also relieve peripheral neuropathy induced by chemotherapy, diabetes or other diseases. In addition, acetyl-L-carnitine may modulate the immune response by increasing T-lymphocytes maturation and may downregulate pro-inflammatory cytokines in response to viruses, such as SARS-CoV-2. It may also disrupt the ACE2 signaling pathway and inhibit the production of reactive oxygen species (ROS).

Vanillyl Alcohol (3-Methoxy-4-hydroxybenzyl alcohol) possesses anti-angiogenic, anticonvulsive, anti-inflammatory, anti-oxidant, neuroprotective, and anti-nociceptive activities. Vanillyl alcohol can effectively inhibit the cytotoxicity and improved cell viability in 1-methyl-4-phenylpyridinium (MPP+)-induced MN9D dopaminergic cells, it also can attenuate the elevation of reactive oxygen species (ROS) levels, decrease in the Bax Bcl-2 ratio and poly (ADP-ribose) polymerase proteolysis.

Lycopene (ψ,ψ-Carotene) is a linear, unsaturated hydrocarbon carotenoid, the major red pigment in fruits such as tomatoes, pink grapefruit, apricots, red oranges, watermelon, rosehips, and guava. As a class, carotenoids are pigment compounds found in photosynthetic organisms (plants, algae, and some types of fungus), and are chemically characterized by a large polyene chain containing 35-40 carbon atoms; some carotenoid polyene chains are terminated by two 6-carbon rings. In animals, carotenoids such as lycopene may possess antioxidant properties which may retard aging and many degenerative diseases. As an essential nutrient, lycopene is required in the animal diet.

Sodium dichloroacetate (BCA) , a specific inhibitor of pyruvate dehydrogenase kinase (PDK) with IC50 values of 183 and 80 μM for PDK2 and PDK4 respectively, has been shown to derepress a mitochondrial potassium-ion channel axis, trigger apoptosis in cancer cells, and inhibit tumor growth.

3,5-Di-tert-butylphenol induces accumulation of reactive oxygen species. 3,5-Di-tert-butylphenol exhibits anti-biofilm and antifungal activities.

Uric acid sodium is a potent and widely recognized antioxidant with the ability to scavenge oxygen free radicals, helping to maintain blood pressure stability and counteract oxidative stress. It effectively eliminates reactive oxygen species (ROS), such as singlet oxygen and peroxynitrite, and inhibits lipid peroxidation. Additionally, uric acid sodium is closely associated with the pathogenesis of gouty arthritis and the formation of calcium oxalate stones, and it can be used to induce hypertension models.

DL-Glyceraldehyde (Glyceric aldehyde) is produced from the action of the enzyme glyceraldehyde dehydrogenase, which converts glycerol to glyceraldehyde using NADP as a cofactor. When present at sufficiently high levels, DL-Glyceraldehyde can be a cytotoxin and a mutagen. A cytotoxin is a compound that kills cells. A mutagen is a compound that causes mutations in DNA. DL-Glyceraldehyde is a highly reactive compound that can modify and cross-link proteins. DL-Glyceraldehyde modified proteins appear to be cytotoxic, depress intracellular glutathione levels, and induce reactive oxygen species (ROS) production (PMID: 14981296 ). DL-Glyceraldehyde has been shown to cause chromosome damage to human cells in culture and is mutagenic in the Ames bacterial test.

Ammonium formate (Formic acid ammonium salt) is the simplest carboxylic acid. Formate is an intermediate in normal metabolism. It is responsible for both metabolic acidosis and disrupting mitochondrial electron transport and energy production by inhibiting cytochrome oxidase activity, the terminal electron acceptor of the electron transport chain. Cell death from cytochrome oxidase inhibition by formate is believed to result partly from depletion of ATP, reducing energy concentrations so that essential cell functions cannot be maintained. Furthermore, inhibition of cytochrome oxidase by formate may also cause cell death by increased production of cytotoxic reactive oxygen species (ROS) secondary to the blockade of the electron transport chain.

Nerol (Neryl alcohol) is a monoterpene found in many essential oils, such as lemon balm and hop.Nerol can lessened the severity of ouabain-triggered arrhythmias in mammalian heart.

Ethyl 3,4-dihydroxybenzoate (EDHB): a prolyl hydroxylase inhibitor attenuates acute hypobaric hypoxia mediated vascular leakage in brain.

Rifamycin S is a potent DNA-dependent RNA polymerase inhibitor,is a quinone and an antibiotic agnet against Gram-positive bacteria

Chlorahololide D is a natural lindane-type sesquiterpene dimer and selective potassium channel blocker that stimulates reactive oxygen species ROS levels to cause cell cycle arrest in the G2 phase, modulates Bcl-2 and Bax and FAK, thereby inhibiting MCF-7 cell growth and triggering apoptosis. Chlorahololide D inhibits tumor proliferation, migration and angiogenesis in in vivo experiments and has anti-breast cancer potential.

Sanguinarine chloride (Pseudochelerythrine chloride), a benzophenanthridine alkaloid, stimulates apoptosis by activating the production of reactive oxygen species (ROS).
