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.
