Macrocyclicantibiotics examples The relentless rise of antimicrobial resistance (AMR) poses a significant global health threat, necessitating the development of novel therapeutic agents with unique mechanisms of action. Emerging from cutting-edge research, tethered macrocyclic peptides represent a promising new class of antibiotics poised to combat even the most formidable drug-resistant bacteria. This innovative approach in antibiotic development is showing exceptional efficacy, particularly against challenging pathogens like carbapenem-resistant *Acinetobacter baumannii* (CRAB).

At the forefront of this discovery is zosurabalpin, a groundbreaking tethered macrocyclic peptide antibiotic. This molecule is not merely another addition to the antibiotic arsenal; it represents a structurally distinct compound class of antibiotics with a differentiated mode of action. Unlike conventional antibiotics, tethered macrocyclic peptides, like zosurabalpin, are designed to disrupt essential bacterial processes in novel ways.2024年1月26日—A new class of antibiotic chemicals -tethered macrocyclic peptides (MCP) that have proven effective against Carbapenem-resistant Acinetobacter baumannii. For instance, zosurabalpin specifically targets the lipopolysaccharide (LPS) transport pathway in Gram-negative bacteria. By inhibiting lipopolysaccharide-transport, it effectively compromises the integrity of the bacterial outer membrane, leading to cell death. This unique mechanism is crucial in overcoming resistance mechanisms that have rendered many existing antibiotics ineffective.
