Sodium citrate dihydrate is an orally active natural product that can be found in citrus fruits. Sodium citrate dehydrate can inhibit the proliferation of tumor cells and induce apoptosis. Sodium citrate dehydrate has antibacterial, anti-tumor and antioxidant activities. Sodium citrate dehydrate can be prepared as a cosolvent or buffer.

(±)-Eudesmin ((±)-Eudesmine) is a natural compound found in Fragaria nubicola with in vitro anti-inflammatory activity. (±)-Eudesmin inhibits NO production in LPS-activated macrophages; suppresses myeloperoxidase-dependent ROS production in zymosan-activated phagocytes; and inhibits superoxide anion production in PMA-activated macrophages. (±)-Eudesmin can be used for the research of inflammation-related diseases.

TEMPOL-H is the reduced hydroxylamine form of the stable nitroxide radical Tempol (HY-100561), and serves as the active metabolite of OT-551 (HY-W556870). TEMPOL-H acts as a potent antioxidant and free radical scavenger. TEMPOL-H protects retinal pigment epithelial cells from acute light-induced damage, and protects mice from lethal whole-body radiation. TEMPOL-H inhibits lens opacification in mice, prevents glutathione loss in rat lenses under stress, blocks protein leakage in rhesus monkey lenses under stress, and maintains the ³H-choline accumulation capacity of the lens. TEMPOL-H can be used in studies related to light-induced retinal pigment epithelial degeneration and age-related cataract.

Isocistanoside C is a phenylethanoid glycoside that can be isolated from Cistanche deserticola. Isocistanoside C exhibits antioxidant activity and inhibits the production of NO.

Dendrocandin E is a bibenzyl derivative and antioxidant found in the stems of Dendrobium candidum, with an IC₅₀ of 15.6 μM for DPPH radical scavenging. Dendrocandin E scavenges DPPH free radicals.

Violaxanthin (HPLC≥90%) is a naturally derived diepoxy xanthophyll carotenoid and light-harvesting accessory pigment with biological activities such as antioxidation and anti-inflammation. Violaxanthin (HPLC≥90%) transfers excitation energy to chlorophyll a under low-light conditions. Violaxanthin (HPLC≥90%) participates in the xanthophyll cycle and dissipates excess light energy in the form of heat, thereby protecting thylakoid membrane lipids from photo-oxidative damage. Violaxanthin (HPLC≥90%) exhibits activities including inhibition of lipid peroxidation, quenching of singlet oxygen, scavenging of DPPH free radicals, and scavenging of ABTS⁺ free radicals. Violaxanthin (HPLC≥90%) can be used in antioxidant-related research.

dsNec-1 is a radical-trapping antioxidant. dsNec-1 inhibits lipid peroxidation. dsNec-1 inhibits ferroptosis in mouse embryonic fibroblasts.

AChE-IN-119 is a selective acetylcholinesterase (AChE) inhibitor with an IC₅₀ of 0.0641 μM and a K_i of 0.01648 μM. AChE-IN-119 exerts antioxidant effects by scavenging DPPH free radicals. AChE-IN-119 exhibits mixed-type inhibition and interacts with both the catalytic active site and the peripheral anionic site of acetylcholinesterase. AChE-IN-119 can be used for the research of Alzheimer's disease.
