Battle against Vancomycin-Resistant Bacteria: Recent Developments in Chemical Strategies

摘要

Vancomycin, a natural glycopeptide antibiotic, was used as the antibiotic of last resort for the treatment of multidrug-resistant Gram-positive bacterial infections. However, almost 30 years after its use, resistance to vancomycin was first reported in 1986 in France. This became a major health concern, and alternative treatment strategies were urgently needed. New classes of molecules, including semi-synthetic antibacterial compounds and newer generations of the previously used antibiotics, were developed. Semisynthetic derivatives of vancomycin with enhanced binding affinity, membrane disruption ability, and lipid binding properties have exhibited promising results against both Gram-positive and Gram-negative bacteria. Various successful approaches developed to overcome the acquired resistance in Gram-positive bacteria, intrinsic resistance in Gram-negative bacteria, and other forms of noninherited resistance to vancomycin have been discussed in this Perspective.
