Cancer cells can avoid and suppress immune responses through activation of inhibitory immune checkpoint proteins, such as PD-1, PD-L1, and CTLA-4. Blocking the activities of these proteins with monoclonal antibodies, and thus restoring T cell function, has delivered breakthrough therapies against cancer. In this review, we describe the latest work on structural characterization of the checkpoint proteins,...
The protein–protein interaction of p53 and MDM2/X is a promising non genotoxic anticancer target. A rapid and efficient methodology was developed to synthesize the 2,3′-bis(1′H-indole) heterocyclic scaffold 2 as ester, acid and amide derivatives. Their binding affinity with MDM2 was evaluated using both fluorescence polarization (FP) assay and HSQC experiments, indicating good inhibition and a perfect...
