Investigation into the functional impact of the vancomycin C-ring aryl chloride.


ABSTRACT: A vancomycin aglycon analogue that possesses a reduced C-ring and an intact E-ring chloride was prepared and its antimicrobial activity towards Staphylococcus aureus and binding affinity to model cell wall ligands were established. Comparison of the derivative with a series of vancomycin aglycon analogues that possess and lack the chloro substituents on the aryl C- and E-rings defines the impact and further refines the role the C-ring chloride plays in promoting both target binding affinity and binding selectivity for d-Ala-d-Ala and its impact on antimicrobial activity.
