Xylopine is an aporphine alkaloid with cytotoxic activity on cancer cells. Xylopine induces oxidative stress, causes G2/M cell cycle arrest and apoptosis in cancer cells.

Euparin, a monomeric compound of Benzofuran, is a reactive oxygen species (ROS) inhibitor. Euparin shows antiviral activity against poliovirus, and also has antidepressant effects.

N-Acetyl-L-cysteine ethyl ester is an esterified form of N-acetyl-L-cysteine (NAC). N-Acetyl-L-cysteine ethyl ester exhibits enhanced cell permeability, and produce NAC and cysteine. N-Acetyl-L-cysteine ethyl ester increases circulating hydrogen sulfide (H2S) and can be used as an H2S producer. N-Acetyl-L-cysteine ethyl ester has the potential to substitute NAC as a mucolytic agent, and as a GSH-related antioxidant.

Heme Oxygenase-1-IN-2 is a novel heme oxygenase-1 inhibitor (IC50 = 0.95 μM) with potent in vitro antiproliferative activity.

XJB-5-131 is a mitochondria-targeted ROS and electron scavenger. XJB-5-131 is a bi-functional antioxidant that comprises a radical scavenger. XJB-5-131 is a synthetic antioxidant that targets mitochondria. XJB-5-131 is an effective ionizing irradiation protector and mitigator of cord blood mononuclear cells (CB MNCs).

Crocin-4, a carotenoid constituent of saffron, is a potent and brain-penetrant antioxidant agent. Crocin-4 can inhibit the aggregation and the concomitant deposition of Aβ fibrils in the brain. Crocin-4 can be used for the research of Alzheimer's Disease. Crocin-4 also exhibits antitumor and anti-inflammatory activities.

Dihydromyristicin, a plant flavonoid, has potent anti-inflammatory properties. Dihydromyristicin reduces endotoxic inflammation via repressing ROS-mediated activation of PI3K/Akt/NF-κB signaling pathways.

Fusarochromanone (FC-101) is a fungal metabolite with potent anti-angiogenic and anti-cancer activity. Fusarochromanone-activated JNK pathway is attributed to induction of reactive oxygen species (ROS).

Ecabet sodium (TA-2711) is currently applied to some clinical gastrointestinal disease by inhibiting the ROS production and improving Helicobacter pylori eradication. Ecabet sodium reduces apoptosis

D-Isofloridoside, one of the polysaccharide precursors, has the activity of scavenging free radicals, inhibiting ROS expression, and inhibiting MMP-2 and MMP-9.
