Antimicrobial
peptides (AMPs) are amphipathic molecules displaying
broad-spectrum bactericidal activity, providing opportunities to develop
a new generation of antibiotics. However, their use is limited either
by poor metabolic stability or by high hemolytic activity. We herein
addressed the potential of thiazole-based γ-peptide oligomers
named ATCs as tunable scaffolds to design polycationic AMP mimetics.
Knowing the side chain distribution along the backbone, we rationally
designed facially amphiphilic sequences with bactericidal effect in
the micromolar range. Since no hemolytic activity was detected up
to 100 μM, this class of compounds has shown the potential for
therapeutic development.
Proteins play a central role for the signal transmission in living systems since they are able to recognize specific biomolecules acting as cellular receptors, antibodies or enzymes; or being themselves...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
