Abstract

High-throughput screening of 700,000 small molecules has identified 235 inhibitors of the GroEL/GroES-mediated refolding cycle. Dose-response analysis of a subset of these hits revealed that 21 compounds are potent inhibitors of GroEL/GroES-mediated refolding (IC₅₀ <10 μM). The screening results presented herein represent the first steps in a broader aim of developing molecular probes to study chaperonin biochemistry and physiology.
