Small‐Molecule Inhibitors of MicroRNA miR‐21 Function

Abstract

MicroRNAs (miRNAs) have recently emerged as an important class of gene regulators, and their misregulation has been linked to a variety of cancers. Small molecule inhibitors of miRNAs would be important tools to elucidate the detailed mechanisms of miRNA function and provide lead structures for the development of new therapeutics. We are reporting a cellular screen for miRNA pathway inhibitors and the first small molecule modifiers of miRNA function.
