Synergistic enhancement of the potency and selectivity of small molecule transcriptional inhibitors.


ABSTRACT: In spite of their considerable therapeutic potential, the development of highly potent and selective transcriptional inhibitors has proven elusive. We demonstrate that combinations of transcriptional inhibitors of erbB2 expression and existing therapeutic agents that target erbB2 activity and lifetime lead to a synergistic increase in activity, with dose reductions as high 30 fold compared to individual agents. The synergy is selective for erbB2 overexpressing cancer cells. These results highlight the potential of a generalizable approach that will improve the utility of transcriptional inhibitors as both biochemical tools and potential therapeutics.
