Discovery of C13-Aminobenzoyl Cycloheximide Derivatives that Potently Inhibit Translation Elongation.
J.Am.Chem.Soc. 143 13473 13477 (2021)
PMID: 34403584 DOI: 10.1021/jacs.1c05146

Abstact

Employed for over half a century to study protein synthesis, cycloheximide (CHX, 1) is a small molecule natural product that reversibly inhibits translation elongation. More recently, CHX has been applied to ribosome profiling, a method for mapping ribosome positions on mRNA genome-wide. Despite CHX's extensive use, CHX treatment often results in incomplete translation inhibition due to its rapid reversibility, prompting the need for improved reagents. Here, we report the concise synthesis of C13-amide-functionalized CHX derivatives with increased potencies toward protein synthesis inhibition. Cryogenic electron microscopy (cryo-EM) revealed that C13-aminobenzoyl CHX (8) occupies the same site as CHX, competing with the 3' end of E-site tRNA. We demonstrate that 8 is superior to CHX for ribosome profiling experiments, enabling more effective capture of ribosome conformations through sustained stabilization of polysomes. Our studies identify powerful chemical reagents to study protein synthesis and reveal the molecular basis of their enhanced potency.
