Abstact

[Image: see text] Throwing tumors a left hook punch: The oncoprotein MDM2 negatively regulates the activity and stability of the tumor suppressor protein p53, and is an important molecular target for anticancer therapy. Mirror image phage display identifies a high-affinity D-peptide ligand of MDM2 that can be developed into a potent and protease-resistant p53 activator with potential antitumor activity.
