A Further Study of the Cyclization of Ureido Derivatives of Unsymmetrical Iminodi-basic Acids Together with the Synthesis of Certain Hydantoins and Other Related Compounds1
Synthesis and Biological Evaluation of Novel Dispiro Compounds based on 5-Arylidenehydantoins and Isatins as Inhibitors of p53–MDM2 Protein–Protein Interaction
A series of novel hydantoin-based dispiroindolinones as potential small-molecule inhibitors of p53–MDM2 protein–proteininteraction were synthesized by two methods, using 2-arylidenehydantoins as starting materials. Some compounds demonstrate moderate cytotoxicity against cancer cell lines with IC50 in micromolar concentration range, which is comparable to nutlin-3. Two of the synthesized dispiroindolinones
