Type:

Peroxynitrite - ONOO

Abbreviation: ONOO−, Peroxynitrite

Type: Reactive nitrogen species / oxidant and nitrating species

Function: Peroxynitrite is a highly reactive nitrogen species formed primarily by the rapid reaction of nitric oxide with superoxide. It oxidizes and nitrates proteins, lipids, DNA, and mitochondrial components and can alter enzyme activity, membrane function, redox signaling, and cellular viability. Peroxynitrite is an important source of protein tyrosine nitration and formation of 3-nitrotyrosine.

Cancer: ↑ Frequently elevated in inflammatory and oxidative tumor microenvironments. Increased peroxynitrite can promote DNA damage, genomic instability, protein nitration, mitochondrial dysfunction, inflammatory signaling, immune suppression, and tumor progression. However, sufficiently high peroxynitrite levels can also induce cancer-cell death, making its effects concentration- and context-dependent.

Alzheimer's Disease: ↑ Increased peroxynitrite formation and nitrosative stress are associated with Alzheimer's disease. Elevated ONOO− contributes to protein nitration, mitochondrial dysfunction, lipid oxidation, DNA damage, synaptic impairment, and neuronal injury. Increased 3-nitrotyrosine in Alzheimer's disease is commonly used as indirect evidence of elevated peroxynitrite-mediated damage.

7902- VT,    Vitexin Protects Against Scopolamine-Induced Cognitive Impairment by Preserving Synaptic Integrity and Modulating Nrf2/HO-1 and NF-κB Signaling Pathways
- in-vivo, AD, NA
*Dose↝, Sco (2 mg/kg/day, i.p.), Sco + vitexin (30 mg/kg/day, oral), Sco + donepezil (1.5 mg/kg/day, i.p.), vitexin alone, and donepezil alone
