Anti-virulence factor-IN-2

Anti-virulence factor-IN-2 (compound C7) is an inhibitor targeting the virulence factor KpsM in Escherichia coli. KpsM facilitates the translocation of capsular polysaccharides to the cell surface, enabling KpsM-positive E. coli to evade phagocytosis by the scavenger receptor Marco on liver Kupffer cells, promoting bacterial dissemination. These bacteria can exacerbate ethanol-induced liver disease. Anti-virulence factor-IN-2 demonstrates anti-infective activity by inhibiting KpsM-dependent capsulation in a mouse model of ethanol-induced liver disease. This compound is applicable for alcoholic hepatitis research.
