WebDisufenton sodium is the disulfonyl derivative of the neuroprotective nitrone spin trap phenylbutylnitrone or "PBN". PBN and its derivatives hydrolyze and oxidize in vitro to form respectively MNP-OH (AKA, NtBHA) and its parent spin-trap MNP. Research [ edit] Disufenton sodium was under development at the drug company AstraZeneca. WebDec 1, 2004 · The efficacy of four antioxidant agents to reduce neurological deficits and mortality produced by sequential common carotid artery sectioning (SCAS) in mice was evaluated. Ascorbic acid (AA, 500 mg/kg), dihydrolipoic acid (DHLA, 100 mg/kg), tert‐butylhydroquinone (t‐BHQ, 100 mg/kg) or phenylbutylnitrone (PBN, 100 mg/kg) were …
WebSep 23, 2024 · Proteasomal enhancement was blocked by pretreatment with a free radical spin trap and ROS inhibitor [ 38, 39 ], phenylbutylnitrone ( PBN ). NOX and catalase activities also were enhanced by EtOH exposure over a time course congruent with the reduction in BRCA1 protein and prevented by PBN pretreatment. WebResults show that the spin trap PBN can prolong lifespan and support the free radical theory of aging. Free radicals and oxidative damage have been proposed as underlying factors in …
WebAug 23, 2007 · Phenylbutylnitrone (PBN) derivatives such as NXY-059 hydrolyze to produce the corresponding benzaldehyde plus N -t-butylhydroxylamine (NtBHA). 2–7 Itself a potent radical scavenger, NtBHA readily oxidizes to its parent spintrap, MNP or “2-methyl-2-nitrosopropane”, AKA, “t-nitrosobutane”. WebJan 7, 2024 · Pollution from air and sunlight has adverse effects on human health, particularly skin health. It creates oxidative stress, which results in skin diseases, including skin cancer and aging. Different types of antioxidants are used as preventative actives in skin-care products.
