NAB815

NAB815 is a specific inhibitor of the Stx2a (Kd = 0.01 μM) /TLR4 interaction. NAB815 inhibits the neutrophil/Stx2a interaction (IC50 = 0.057 μg/mL) . NAB815 inhibits the formation of Stx2-containing extracellular vesicles (EVs) produced by leukocytes and platelets and reduces their toxic effects in cellular (Vero cells) and animal models (CD-1 mice) . NAB815 reduces bacterial loads in the kidneys, urine, and bladders of Escherichia coli-infected mice. NAB815 is useful in the study of hemolytic uremic syndrome (HUS) [1][2].
