<p>Cysteine peptide (Ac RFAAKAA COOH) is used in combination with Lysinepeptide (Ac RFAACAA COOH) in the Direct Peptide Reactivity Assay (DPRA) test.<br>Direct Peptide Reactivity Assay is used in cosmetic applications for the characterization of the skin sensitizing potential of a substance, framed by OECD Guideline no 442.<br>The molecular initiating event (MIE) in skin sensitization is a binding between epidermal proteins and the sensitizing chemical substance. MIE is part of the adverse outcome pathway (AOP) of skin sensitization.<br>It is thanks to the properties of Lysine peptide and Cysteine peptide that the chemical binding will be able to take place, so these synthetic heptapeptides will mimic the reaction of a skin exposed to a substance.<br>Binding between nucleophilic proteins and electrophile substance will be measured by High Performance Liquid Chromatography (HPLC). Therefore, the decrease in Lysine peptide and Cysteine peptide levels will be a sign of sensitizing event. Depending on the rate of depletion, the sensitizing character of a molecule will be determined (see table at the bottom of the page).<br>In chemico DPRA test also has wider applications such as hazard classification in cosmetics, but also for pharmaceuticals and biocides. It is a good alternative to animal experimentation.</p>

<p>Lys-Ala-AMC is an activator of ion channels and a ligand for receptors. It is used in research as a tool to study protein interactions, receptor pharmacology, and ion channel pharmacology. Lys-Ala-AMC binds to the α-subunit of voltage gated calcium channels and can activate these channels by increasing the rate of opening. This peptide also inhibits receptor binding by competing with the natural ligand. It has been shown to be an antagonist at the NMDA receptor and can inhibit the binding of glycine to this receptor.</p>

<p>IL-1α is a cytokine protein that has been shown to be involved in the immune system. IL-1α is an activator of the receptor and is also a ligand for it. The protein has been shown to activate ion channels, which are proteins that allow ions to pass through either by diffusion or by facilitated transport. This activation causes cells to produce more hydrogen ions, which leads to an increase in the acidity of the cell. IL-1α has also been shown to inhibit cell proliferation and induce apoptosis.</p>

<p>Peroxiredoxin-1 is a protein that belongs to the peroxiredoxin family. It is a redox-active protein that can reduce hydroperoxides and organic hydroperoxides. Peroxiredoxin-1 has been shown to be an activator of ion channels, receptors, and ligands. It is used as a research tool for studying the interactions between proteins and peptides.</p>

<p>Azido-dPEG®3-Amine is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Azido-dPEG®3-Amine is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.</p>

<p>Myelin oligodendrocyte glycoprotein (MOG) is a myelin protein found in the central nervous system. MOG is a ligand for CD200, which is an inhibitory receptor expressed by astrocytes. It has been shown that MOG can induce the proliferation and differentiation of primary cultures of rat astrocytes in vitro. MOG induces the production of reactive oxygen species in mitochondria and increases the expression of acid-binding protein, which are both important factors in the demyelination process. MOG has also been implicated as a potential factor in the development of multiple sclerosis. Further research into this protein may lead to new treatments or cures for disorders such as encephalomyelitis, nervous system diseases, or even cancer.</p>

<p>Seglitide is a cyclic peptide that is a model system for the receptor activity of somatostatin. Somatostatin inhibits cells by binding to its receptors, which are found on the surface of endocrine cells and in the hypothalamus. Seglitide has been shown to inhibit cell growth in tissue culture and is a potent inhibitor of epidermal growth factor (EGF) production. Seglitide also activates locomotor activity in mice, suggesting that it may have some clinical relevance. Structural analysis has revealed that seglitide's amino acid sequence is similar to somatostatin's, making them closely related compounds. It also binds to DNA-dependent RNA polymerase, preventing transcription and replication.</p>

<p>CJC-1295 is a synthetic peptide, which is an analogue of growth hormone-releasing hormone (GHRH). It is synthesized through recombinant DNA technology, which allows for precise control over its sequence and length. This particular peptide is designed to bind to GHRH receptors in the pituitary gland. By activating these receptors, CJC-1295 stimulates the release of growth hormone (GH) into the bloodstream.The primary function of CJC-1295 is to influence the endocrine system, particularly enhancing the release of endogenous growth hormone. It achieves this by increasing the amplitude and frequency of GH pulses without affecting the natural negative feedback mechanisms that regulate GH production. This mode of action distinguishes CJC-1295 from other growth hormone therapies, as it promotes a more physiological pattern of hormone secretion.CJC-1295 is used in various scientific contexts, primarily in research focusing on growth hormone deficiencies, muscle wasting conditions, and certain metabolic disorders. Its ability to increase GH release also makes it a subject of interest in studies related to aging, tissue repair, and regeneration. The longer half-life of CJC-1295 compared to natural GHRH peptides further enhances its applications in research, allowing for more sustained and controlled experimentation.</p>

<p>H-His-Arg-OH is a synthetic peptide that has been shown to have cytotoxic effects on mammalian cells. The H-His-Arg-OH peptide can be used for the treatment of heart disease and autoimmune diseases, such as rheumatoid arthritis. This peptide has been found to be resistant to congestive heart failure, which is caused by a number of factors, including hypertension and valvular stenosis. It has also been shown to have an immunoglobulin G1 (IgG1) genotype.</p>

<p>Adriamycin is an anticancer drug that is a structural analogue of aspartic acid. It can be synthesized in a solid-phase synthesis using a polymeric resin with an acidic functional group, such as H-Asp-Ala-OH. Adriamycin inhibits the production of inflammatory cytokines and prostaglandins, which are involved in the development of inflammatory diseases. Adriamycin has been shown to have anti-inflammatory effects on human serum and to inhibit the production of proteins important for tumor cell proliferation. Adriamycin also has anti-inflammatory properties due to its ability to bind with hydrogen bonds to acidic residues on proteins.<br>END&gt;</p>
