The use of small molecule inhibitors in the study of cellular processes is a powerful approach to understanding gene function. During the course of a high throughput screen for novel inhibitors of eukaryotic translation, we identified a number of nucleic acid binding ligands that showed activity in our assay. When tested on a panel of mRNA transcripts displaying different modes of translation initiation, these ligands showed a range of biological activities - with some inhibiting both cap-dependent and internal initiation and others preferentially blocking internal initiation. We used this information to identify a novel threading intercalator that inhibits Hepatitis C virus internal initiation.
