Antimicrobial resistance crisis for bacterial infections The current crisis caused by antimicrobial resistance [1][2] demands new strategies to fight infections. Antibiotics have served as

• plasma and liver microsomes, absence of cytotoxicity, and excellent oral bioavailability in mice. 4. Direct toxin inhibition Numerous bacteria secrete toxins that are responsible for acute virulence. Various small molecule and antibody approaches target the inhibition of bacterial toxins in order to

• diarrhea is an AB5 toxin released by the bacteria. Thus, an understanding of this toxin becomes essential in finding/developing molecules that could prevent cell entry of the toxin and inhibit its activity. AB5 toxins are an important class of bacterial toxins. They consist of a single A-subunit and a

• induced upon crosslinking the gold nanoparticles with CTB or LTB as a strategy for detecting the bacterial toxins. Conclusion Cholera and related diseases caused by other bacterial toxins remain a substantial threat to society. This challenge, and a molecular understanding of the basis of toxin action

• , has driven the development of diverse inhibitors over many years and this area of research continues to flourish with imaginative and novel strategies emerging for potential antiadhesive therapeutics. Further advances in our understanding of the structural biology of bacterial toxins, in particular

• ligands for the Shiga-like [14][15] and cholera toxins [16][17] both belonging to the AB5 family of bacterial toxins. The frequent observation that the binding affinity of a multivalent ligand increases exponentially with the number of binding sites has been termed the glycoside cluster effect [18][19
