Restoration of p53 activity by inhibition of the p53-MDM2 interaction has been considered an attractive approach for Cancer treatment. However, the hydrophobic protein-protein interaction surface represents a significant challenge for the development of small-molecule inhibitors with desirable pharmacological profiles. RG7112 was the first small-molecule p53-MDM2 inhibitor in clinical development. Here, we report the discovery and characterization of a second generation clinical MDM2 Inhibitor, RG7388, with superior potency and selectivity.
