Target Structure-Based Discovery of Small Molecules that Block Human p53 and CREB Binding Protein (CBP) Association
Contents |
Overview
Lysine acetylation of human tumor suppressor p53 in response to cellular stress signals is required for its function as a transcription factor that regulates cell cycle arrest, senescence, or apoptosis. Here, we report small molecules that block lysine 382-acetylated p53 association with the bromodomain of the coactivator CBP, an interaction essential for p53-induced transcription of the cell cycle inhibitor p21 in response to DNA damage. These chemicals were discovered in target structure-guided nuclear magnetic resonance spectroscopy screening of a focused chemical library constructed based on the structural knowledge of CBP bromodomain/p53-AcK382 binding. Structural characterization shows that these chemicals inhibit CBP/p53 association by binding to the acetyl-lysine binding site of the bromodomain. Cell-based functional assays demonstrate that the lead chemicals can modulate p53 stability and function in response to DNA damage.
