Complement System
The complement system, composed of more than 30 serum and cell surface components, is collaborating in recognition and elimination of pathogens as a part of both the innate and acquired immune systems. Once the complement system is activated, a chain of reactions involving proteolysis and assembly occurs, resulting in cleavage of the third complement component (C3). The cascade up to C3 cleavage is called the activation pathway. There are three activation pathways: the classical, lectin, and alternative pathways.
The complement cascade is a dual-edged sword, causing protection against bacterial and viral invasion by promoting phagocytosis and inflammation. Pathologically, complement can cause substantial damage to blood vessels (vasculitis), kidney basement membrane and attached endothelial and epithelial cells (nephritis), joint synovium (arthritis), and erythrocytes (hemolysis) if it is not adequately controlled.

4-Octylphenol
0 ImagesReferencia número: HY-W130878No. CAS: 1806-26-44-Octylphenol is a hormone disruptor that has gender-specific effects on male reproductive cells, significantly reducing the mitotic index and the number of spermatogonia. 4-Octylphenol can cause inflammatory damage to fish gills by activating the complement system through the C3a/C3aR axis and the C5a/C5aR1 axis, this leads to complement activation and causes immune suppression due to the imbalance between Th1/Th2 cells and regulatory T cells (Treg)/Th17 cells, as well as inflammatory damage via the Toll-like receptor 7 (Toll-like Receptor (TLR))/IκBα/NF-κB pathway.

Certepetide-13C6,15N2
0 ImagesReferencia número: HY-P3448SSynonyms: CEND-1-13C6,15N2; iRGD-13C6,15N2; LSTA1-13C6,15N2Certepetide-13C6,15N2 (CEND-1-13C6,15N2) is the 13C- and 15N-labeled Certepetide (HY-P3448). Certepetide (CEND-1) is a bifunctional cyclic peptide (a.k.a. iRGD). Certepetide is a tumor-penetrating enhancer via RGD motif interaction with alphav-integrins and via activating NRP-1, and transforms the solid tumor microenvironment into a temporary agent conduit. Certepetide accumulates in tumors, and is used in the research of pancreatic cancer and other solid tumors.

Cyclosporin A-d3
0 ImagesReferencia número: HY-B0579S1No. CAS: 222295-76-3Synonyms: Cyclosporine A-d3; Ciclosporin A-d3; CsA-d3Cyclosporin A-d3 (Cyclosporine A-d3) is the deuterated-labeled Cyclosporin A (HY-B0579). Cyclosporin A (Cyclosporine A) is an immunosuppressant which binds to the cyclophilin and inhibits phosphatase activity of protein phosphatase 2B (PP2B/calcineurin) with an IC50 of 5 nM. Cyclosporin A is a molecular glue, binds to cyclophilin and calcineurin, leading to inactivation of nuclear Factor of activated T Cells (NFAT) and a subsequent decrease in the immune response. Cyclosporin A also inhibits CD11a/CD18 adhesion.
