Potent and Orally Active Small-Molecule Inhibitors of the MDM2−p53 Interaction
摘要:
We report herein the design of potent and orally active small-molecule inhibitors of the MDM2-p53 interaction, Compound 5 binds to MDM2 with a K-i of 0.6 nM, activates p53 at concentrations its low as 40 nM, and potently and selectively inhibits cell growth in tumor cells with wild-type p53 over tumor cells with mutated/deleted p53. Compound 5 has a good oral bioavailability and effectively inhibits tumor growth in the SJSA-1 xenograft model.
Provided herein are compounds, compositions, and methods in the field of medicinal chemistry. The compounds and compositions provided herein relate to spiro-oxindoles which function as antagonists of the interaction between p53 and MDM2, and their use as therapeutics for the treatment of cancer and other diseases.

which affords four diastereomers from a single compound. Our biochemical binding data showed that the stereochemistry in this class of compounds has a major effect on their binding affinities to MDM2, with >100-fold differencebetween the most potent and the least potent stereoisomers. Our study has led to the identification of a set of highly potent MDM2 inhibitors with a stereochemistry that is different
