Affinity chromatography reveals direct binding of the GATA4-NKX2-5 interaction inhibitor (3i-1000) with GATA4.

ABSTRACT: Heart failure is a serious medical condition with a poor prognosis. Current treatments can only help manage the symptoms and slow the progression of heart failure. However, there is currently no cure to prevent and reverse cardiac remodeling. Transcription factors are in a central role in various cellular processes, and in the heart, GATA4 and NKX2-5 transcription factors mediate hypertrophic responses and remodeling. We have identified compounds that modulate the synergistic interaction of GATA4 and NKX2-5 and shown that the most promising compound (1, 3i-1000) is cardioprotective in vitro and in vivo. However, direct evidence of its binding site and mechanism of action has not been available. Due to the disordered nature of transcription factors, classical target engagement approaches ca
