Eritoran

Eritoran （E5564 free base） is a Toll-like receptor 4 (TLR4) antagonist. Eritoran protects mice against lethal influenza virus infection, such as Ebola virus (EBOV), Marburg virus (MARV). Eritoran decreases the level of granulocytosis, may alleviate the severity of the "cytokine storm". Eritoran inhibits pathogenesis of filovirus infection. Eritoran has anti-inflammatory activity[1][2].
