M351-0056
Based on 1 Customer Validation
M351-0056 is an orally active VISTA agonist with a Kd value of 12.60 μM. M351-0056 inhibits the activation of the JAK2-STAT2 pathway, reduces the phosphorylation levels of JAK2 and STAT2, and regulates type I interferon (IFN-I) and non-canonical NF-κB pathways. M351-0056 decreases the levels of cytokines (IFN-γ, IL-17A, TNF-α, IL-2 and IL-1β). M351-0056 improves imiquimod (HY-B0180)-induced psoriasis-like skin inflammation, reduces autoantibody levels, kidney damage and immune cell expansion in mice susceptible to chronic graft-versus-host disease and lupus, and delays the progression of systemic lupus erythematosus. M351-0056 can be used in research related to psoriasis-like dermatitis and systemic lupus erythematosus.
