Isoindolinone Inhibitors of the Murine Double Minute 2 (MDM2)-p53 Protein−Protein Interaction: Structure−Activity Studies Leading to Improved Potency
摘要:
Inhibition of the MDM2-p53 interaction has been shown to produce an antitumor effect, especially in MDM2 amplified tumors.. The isoindolinone scaffold has proved to be versatile for the discovery of MDM2-p53 antagonists. Optimization of previously reported inhibitors, for example, NU8231 (7) and NU8165 (49), was guided by MDM2 NMR titrations, which indicated key areas of the binding interaction to be explored. Variation of the 2-N-benzyl and 3-alkoxy substituents resulted in the identification of 3-(4-nitrobenzyl)-3-((1-(hydroxymethyl)cyclopropyl)methoxy)-2-(4-nitrobenzyl)isoindolin-1-one (74) as a potent MDM2-p53 inhibitor (IC(50) = 0.23 +/- 0.01 mu M). Resolution of the enantiomers of 74 showed that potent MDM2-p53 activity primarily resided with the (+)R-enantiomer (74a; IC(50) = 0.17 +/- 0.02 mu M). The cellular activity of key compounds has been examined in cell lines with defined p53 and MDM2 status. Compound 74a activates p53, MDM2, and p21 transcription in MDM2 amplified cells and shows moderate selectivity for wild-type p53 cell lines in growth inhibition assays.

The present disclosure relates to bifunctional compounds, which can be used as modulators of targeted ubiquitination. In particular, the present disclosure is directed to compounds that contain on one end a VHL ligand moiety, which binds to the VHL ubiquitin ligase (E3), and on the other end a moiety that binds a target protein such that degradation of the target protein/polypeptide is effectuated. The target protein may be EGFR. Also disclosed are VHL ligands.
