A series of novel amino acid ester derivatives of 2,3-substituted isoindolinones was synthesized and evaluated for p53-mediated apoptotic activity. The rationale for augmentation of the target activity of 2,3-substituted isoindolinones was based on the introduction of new fragments in the structure of the inhibitor that would provide additional binding sites in the hydrophobic cavity of MDM2. To select for the anticipated modifications we employed molecular docking. Synthesized molecules were evaluated for their ability to induce apoptosis in two cancer cell lines and their derivatives with different status of p53 (colorectal HCT116 and osteosarcoma U2OS cells) by Annexin V staining. The target activity was estimated using high-content imaging system Operetta. Valine and phenylglycine ester derivatives were identified as potentially active MDM2-p53 inhibitors.

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-chlorophenyl)-3-((1- (hydroxymethyl)cyclopropyl)methoxy)-2-(4-nitrobenzyl)isoindolin-1-one (74) as a potent MDM2-p53 inhibitor (IC50 = 0.23 A± 0.01 μM). Resolution of the enantiomers of 74 showed that potent MDM2-p53 activity primarily resided with the (+)-R-enantiomer (74a; IC50 = 0.17 A± 0.02 μM). 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.

From a set of weakly potent lead compounds, using in silico screening and small library synthesis, a series of 2-alkyl-3-aryl-3-alkoxyisoindolinones has been identified as inhibitors of the MDM2-p53 interaction. Two of the most potent compounds, 2-benzyl-3-(4-chlorophenyl)-3-(3-hydroxypropoxy)-2,3- dihydroisoindol-1-one (76; IC50 = 15.9 ± 0.8 μM) and 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2, 3-dihydroisoindol-1-one (79; IC50 = 5.3 ± 0.9 μM), induced p53-dependent gene transcription, in a dose-dependent manner, in the MDM2 amplified, SJSA human sarcoma cell line.

A series of 2-N-alkyl-3-aryl-3-alkoxyisoindolinones has been synthesised and evaluated as inhibitors of the MDM2-p53 interaction. The most potent compound, 3-(4-chlorophenyl)-3-(4-hydroxy-3,5-dimethoxybenzyloxy)-2-propyl-2,3- dihydroisoindol-1-one (NU8231), exhibited an IC50 of 5.3 ± 0.9 μM in an ELISA assay, and induced p53-dependent gene transcription in a dose-dependent manner, in the SJSA human sarcoma cell line.
