antioxidative stress

Paeoniflorin (Peoniflorin) is a herbal constituent extracted from the root of Paeonia albiflora Pall.

Matrine (Vegard), an alkaloid isolated from the Sophora genus, acts as a kappa opioid receptor agonist.

Calycosin-7-O-β-D-glucoside (calycosin-7-O-beta-D-glucopyranoside) exhibits a protective effect on rat hepatocytes, inhibits COX-2 activity, has antimicrobial properties, and is a promising anti-HIV agent. Additionally, it demonstrates scavenging activity against DPPH radicals and superoxide anions, alleviates osteoarthritis, and increases brain cell membrane fluidity in ischemia-reperfusion rats.

CL-13 is an inhibitor of butyrylcholinesterase (BChE), exhibiting an IC50 of 1.15 μM and a selectivity index (SI) of 9.2 for acetylcholinesterase. It demonstrates antioxidative activity in SH-SY5Y cells with a DPPHEC50 of 47.01 μM and has the capacity to chelate metals involved in Aβ aggregation and/or oxidative stress, showing no neurotoxicity at concentrations up to 50 μM. CL-13 can also reverse scopolamine-induced cognitive impairments without affecting motor abilities in mice.

Levamlodipine besylate hemipentahydrate is the besylate hemipentahydrate salt form of Levamlodipine. It is an orally effective calcium channel blocker with antioxidative and vasodilatory properties. This compound can reduce serum malondialdehyde (MDA) levels, enhance the activity of superoxide dismutase (SOD), and alleviate oxidative stress. Levamlodipine besylate hemipentahydrate is relevant for research in vascular dementia, hypertension, and cerebrovascular diseases.

Fraxetin (7,8-dihydroxy-6-methoxy coumarin) has dual-antioxidative ,hepatoprotective and antihyperglycemic functions, it shows potent protective effects against CCl4 induced oxidative stress and hepatic fibrosis, has a marked inhibitory effect on S.aureus proliferation. It increased the level of Nrf2/ARE, and HO-1, inhibit the formation of ROS, cytochrome c release, activation of caspase-3 and 9, and suppressed the up-regulation of Bax.

Magnolin reduces the renal oxidative stress, suppresses caspase-3 activity, and increases Bcl-2 expression in vivo and in vitro. Magnolin has anti-inflammatory and antioxidative effects.

1. Eriocitrin (Eriodictyol-7-O-Rutinoside) is powerful antioxidative flavonoid; (1) Prevents oxidative damages caused by acute exercise-induced oxidative stress.(2) Lipid-lowering effects in a rat model of high-fat diet. 2. Dietary Eriocitrin ameliorates diet-induced hepatic steatosis with activation of mitochondrial biogenesis. 3. Eriocitrin and Apigenin were identified as new potent inhibitors of human carbonic anhydrase VA isozyme.

Glutathione ethyl ester is a cell-permeable, modified form of glutathione (GSH) that undergoes rapid hydrolysis by esterases in vivo to restore GSH levels. It inhibits progression in the early stages of diabetes-associated cataract formation and reduces reactive oxygen species (ROS) content, thereby protecting in vitro mature bovine oocytes from oxidative stress.

Fraxinellone analog 1 (compound 2) is an effective and rapid activator of the Nrf2-mediated antioxidative defense system, providing protection against glutamate-mediated excitotoxicity. It induces the expression of antioxidative genes Gpx4, Sod1, and Nqo1. Additionally, Fraxinellone analog 1 exerts neuroprotective effects and modulates oxidative stress and inflammation, making it suitable for research on neurodegenerative diseases.
