Biomed Pharmacother

January 2025

Department of Chemistry, Sungkyunkwan University, Suwon 16419, Republic of Korea. Electronic address:

The impairment of the p53 pathway was once regarded as inadequately druggable due to the specificity of the p53 structure, its flat surface lacking an ideal drug-binding site, and the difficulty in reinstating p53 function. However, renewed interest in p53-based therapies has emerged, with promising approaches targeting p53 and ongoing clinical trials investigating p53-based treatments across various cancers. Despite significant progress in p53-targeted therapies, challenges persist in identifying effective therapeutic targets within the p53 pathway.
