Characterization of the Core Ribosomal Binding Region for the Oxazolidone Family of Antibiotics Using Cryo-EM.

ABSTRACT: Linezolid and tedizolid are oxazolidinones with established clinical utility for the treatment of Gram-positive pathogens. Over time it has become apparent that even modest structural changes to the core phenyl oxazolidinone leads to drastic changes in biological activity. Consequently, the structure-activity relationship around the core oxazolidinone is constantly evolving, often reflected with new structural motifs present in nascent oxazolidinones. Herein we describe the use of cryo-electron microscopy to examine the differences in binding of several functionally different oxazolidinones in the hopes of enhanced understanding of their SAR. Tedizolid, radezolid, T145, and contezolid have been examined within the peptidyl transferase center (PTC) of the 50S ribosomal subunit from methicil
