antioxidant peptide a

Antioxidant peptide A is a short peptide containing alternating aromatic or sulfur-containing amino acids (alternative aromatic or sulfur-containing amino acid).

Antioxidant peptide A acetate is a short peptide, which contains alternative aromatic or sulfur-containing amino acid.

Oxytocin acetate (α-Hypophamine acetate) is a mammalian neurohypophysial hormone, a ligand of oxytocin receptor.

Lactacystin is an orally active, irreversible, and cell-permeable proteasome inhibitor (IC50 = 4.8 μM) that also inhibits the lysosomal enzyme cathepsin A. It induces apoptosis and cell cycle arrest, possesses anticancer, antiviral, and antioxidant activities, can penetrate the blood-brain barrier, and is commonly used in the construction of Parkinson’s disease and dementia models.

β-Amyloid(1-42), human, Ala-13C3,15N trifluoroacetic acid is a β-Amyloid (1-42), human marked with 13C and 15N. This unprocessed HFIP peptide comprises 42 amino acids and is a brain-permeable amyloid fragment, useful for researching Alzheimer's and Down syndrome. In monomer form, β-Amyloid (1-42), human provides antioxidant and neuroprotective effects. Upon HFIP monomerization and DMSO solvent preparation, it forms soluble oligomers (AβOs) at 4°C, which exhibit synaptotoxicity and neurotoxicity, while at 37°C it forms insoluble fibrils with lower neurotoxicity, involved in oxidative damage. Aβ42 oligomers interact with neuronal surface receptors such as PrPc, mGluR5, and NMDA receptor, activating signaling pathways that induce oxidative stress, calcium imbalance, synaptotoxicity, leading to neuronal dysfunction and death.

γ-Glutamyl-S-allylcysteine (L-γ-Glutamyl-(S)-Allyl-Cysteine) is a γ-glutamyl peptide derived from Allium sativum L., known for its anti-glycation and antioxidant properties, as well as its ability to inhibit cholesterol biosynthesis.

δ-Sleep Inducing Peptide (DSIP) is a neuropeptide exhibiting antioxidant and anxiolytic properties.

Antioxidant Agent-9, a peptide featuring the Asp-Trp sequence, exhibits antioxidant properties and demonstrates potential as an antiviral against SARS-CoV-2, possessing an affinity strength comparable to that of Chloroquine and Favipiravir [1] [2].

δ-Sleep Inducing Peptide acetate, a neuropeptide, exhibits antioxidant and anxiolytic properties [1] [2].

AHK, a bioactive peptide known for its antioxidant properties, has been employed as a cosmetic ingredient [1].

Tetrapeptide-1, a bioactive peptide known for its antioxidant properties, is frequently cited as an ingredient in cosmetics [1].

Lunasin, a bioactive peptide derived from soybean, exhibits antioxidant, anti-inflammatory, anticancer, and anti-aging properties. It operates through an epigenetic mechanism linked to histone acetylation and has the ability to penetrate cells and impede the formation of oncospheres in cancer cells [1].

TP4 (Nile tilapia piscidin) is an orally active, piscidin-like antimicrobial peptide that inhibits various gram-positive and gram-negative bacterial strains with a minimum inhibitory concentration (MIC) ranging from 0.03 to 10 μg/mL. It demonstrates hemolytic activity and promotes immune response, antioxidant activity, and intestinal health in the presence of bacterial infections. Additionally, TP4 has an anti-tumor effect and induces necrosis in cancer cells by triggering mitochondrial dysfunction [1] [2] [3].

H-Leu-Leu-Ala-OH, a tripeptide consisting of two L-leucine residues linked to L-alanine via peptide bonds, exhibits antioxidant activities [1].

H-Gly-Gly-Gly-OH, also known as Triglycine, is a tripeptide composed of three glycine amino acids linked by peptide bonds. It is commonly utilized as a model compound in studies of protein structure and function. Glycylglycylglycine may also act as a neurotransmitter in the central nervous system and has demonstrated antioxidant properties. Furthermore, it holds potential research significance in various diseases, such as cancer, diabetes, and neurodegenerative disorders.
