α-Vitamin E is a naturally occurring form of vitamin E with antioxidant and anti-inflammatory activity. α-Vitamin E can be used in research on oxidative stress, lipid peroxidation, membrane damage, and inflammation-related diseases.

1. Aloenin (Aloenin A) and aloe-emodin are active principles for inhibition of c-ADH and c-ALDH activities in vitro.

Homocarnosine is a brain-specific dipeptide composed of γ-aminobutyric acid (GABA) and histidine. As an inhibitory neurotransmitter, homocarnosine is synthesized from GABA within neurons and exerts anticonvulsant effects by enhancing GABA receptor signaling pathways. Homocarnosine also possesses antioxidant and anti-inflammatory properties; it scavenges peroxyl radicals, chelates transition metal ions such as copper, prevents oxidative damage to DNA, and inhibits the formation of advanced glycation end products (AGEs).

AAPH is a water-soluble azo compound which is used extensively as a free radical generator, often in the study of lipid peroxidation and the characterization of antioxidants.[1],[2],[3],[4] Decomposition of AAPH produces molecular nitrogen and 2 carbon radicals. The carbon radicals may combine to produce stable products or react with molecular oxygen to give peroxyl radicals. The half-life of AAPH is about 175 hours (37°C at neutral pH), making the rate of free radical generation essentially constant during the first several hours in solution.[5] While AAPH may be used effectively for lipid peroxidation in aqueous dispersions of fatty acids, other radical generators may be better suited for peroxidation studies in lipid micelles or membranes.[6],[7]

CuATSP is a potent free radical trapping antioxidant (RTA) and ferroptosis inhibitor that reversibly adds a peroxyl radical to a bis (thiosemicarbazone) ligand to inhibit lipid peroxidation, showing therapeutic promise for diseases such as amyotrophic lateral sclerosis (ALS) and Parkinson's disease.

Alloisoimperatorin is a candidate of AChE inhibitors, it displays potent antioxidant effects against the DPPH radical and against renal epithelial cell injury by using AAPH to generate peroxyl radicals in vitro. Alloisoimperatorin has estrogenic activity

Bilirubin ditaurine is a synthetic analog of conjugated bilirubin that can completely inhibit oxidation of phosphatidylcholine induced by peroxyl radicals in multilayer liposomes or micelles. While bilirubin ditaurine itself does not significantly decompose 18:2-OOH, it greatly accelerates copper ion-catalyzed decomposition of 18:2-OOH. Bilirubin ditaurine is useful for studying the detoxification effects of conjugated bilirubin.
