Inhibition of ErbB2(Her2) expression with small molecule transcription factor mimics
摘要:
Small molecules that mimic the transcriptional activation domain of eukaryotic transcriptional activators have the potential to serve as effective inhibitors of transcriptional processes. Here we show that one class of transcriptional activation domain mimics, amphipathic isoxazolidines, can be converted into inhibitors of gene expression mediated by the transcriptional activator ESX through small structural modi. cations. Addition of the small molecules leads to decreased expression of the cell surface growth receptor ErbB2(Her2) in ErbB2-positive cancer cells and, correspondingly, decreased proliferation.

The present invention relates to gene regulation. In particular, the present invention provides small compounds capable of modulating ESX-mediated transcription and related methods of therapeutic and research use. In addition, the present invention provides methods for treating conditions associated with aberrant EGFR expression with ESX-mediated transcription modulators (e.g., ESX-mediated transcription inhibitors).
