1Z105
Based on 1 Customer Validation
1Z105 is an orally active TLR4/MD2 agonist, immunostimulant and vaccine adjuvant. 1Z105 activates NF-κB via the MyD88/TRIF pathway in a CD14-independent manner, with EC50 values of 0.63 µM and 0.77 µM for inducing IL-6 and IL-12 in mBMDCs, respectively. 1Z105 promotes dendritic cell maturation, antigen uptake and cross-presentation; when used alone, it induces Th2-IgG1, while combined with the TLR7 agonist 1V270, it synergistically induces balanced Th1/Th2 responses and provides low-reactogenic protection against homologous, heterologous and heterosubtypic influenza. 1Z105 prevents LPS (HY-D1056A1)- and galactosamine-induced liver injury as well as autoantibody-driven arthritis in mice. 1Z105 can be used in studies related to influenza virus infection, inflammation, and LPS/galactosamine-induced liver injury.
