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 as 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. ...[more]
