Synonyms: Huazhongilexone
Eriodictyol ((±)-Huazhongilexone; Dihydroluteolin) is an orally active TRPV1 receptor antagonist (IC50=44-47 nM, rTRPV1) with antioxidant and anti-inflammatory activities. Eriodictyol effectively inhibits lipid peroxidation and the release of proinflammatory cytokines by specifically antagonizing the TRPV1 receptor and activating the Nrf2 signaling pathway. Eriodictyol reduces the levels of ICAM-1, VEGF, eNOS and TNF-α in the retina and maintains the integrity of the blood-retinal barrier. Eriodictyol alleviates oxidative stress-induced apoptosis and hyperalgesia, enhances the activity and cytotoxicity of immune cells (such as B lymphocytes, NK cells and macrophages), and increases the levels of antioxidant enzymes simultaneously. Eriodictyol can be used in the research of diabetic retinopathy, acute lung injury and various pain-related diseases .

CAS No.: 189261-10-7
Purity:  99.10%
Natalizumab (AN100226; BG00002) is a humanized monoclonal IgG4 antibody inhibitor that selectively targets α4 integrin (CD49d). It blocks the interaction of integrins such as α4β1 (VLA-4) with vascular cell adhesion molecule VCAM-1, intercellular adhesion molecule ICAM-1, and fibronectin by competitively binding to the α4 subunit. Natalizumab inhibits the adhesion, retention, and transendothelial migration of immune cells (such as CD4 + T cells), reducing the infiltration of inflammatory cells into the central nervous system or lesion sites, thus exerting anti-inflammatory and immunomodulatory activity. Natalizumab is used in the study of relapsing-remitting multiple sclerosis (RRMS) and also has applications in the study of autoimmune or inflammation-related diseases such as Crohn's disease, B-cell lymphoma, and non-infectious uveitis. Natalizumab can also prevent lymphocytes from entering the central nervous system, thereby preventing acute demyelinating relapses .
