Cholera versus cholera: The inhibition of multivalent protein/carbohydrate interactions between toxins and glycolipids in cell membranes can prevent the toxins from entering cells. The site-specific modification of a protein scaffold, matched in both size and valency to the target toxin, led to a multivalent inhibitor with an IC50 value of 104 pM for the cholera toxin B-subunit.
