| Description: | Data Source: Sanford-Burnham Center for Chemical Genomics (SBCCG) Source Affiliation: Sanford-Burnham Medical Research Institute (SBMRI, San Diego CA) Network: NIH Molecular Libraries Probe Production Centers Network (MLPCN) Grant Number: R03 MH089489-01 Assay Provider: Dr. Geoffrey M. Wahl, Salk Institute for Biological Studies, San Diego, CA A wild type but attenuated p53 is retained in approximately 50% of human tumors, and reactivation of p53 in such tumors is an attractive chemotherapeutic strategy. p53 activity is restricted in vivo by mdm2 and mdmx, and knockout of either of these proteins is embryonic lethal in a p53-dependent manner (1, 2). Both proteins bind to p53 via a hydrophobic N-terminal pocket and block p53-dependent transcription of genes required for tumor suppression. Efforts to reactivate p53 with small molecules have focused on inhibition of the mdm2/p53 interaction, which leads to increased p53 levels and activity. However, recent reports indicate that targetin |
