Discovery of novel dual inhibitors against Mdm2 and Mdmx proteins by in silico approaches and binding assay

摘要

Aims: The p53 protein, also called guardian of the genome, has a key role in cell cycle regulation. It is activated under stressful circumstances, such as DNA damage which results in permanent arrest or cell death. The protein is disabled in several types of human cancer due to over-expression of the two regulators, Mdm2 and Mdmx. As a result, inhibiting Mdm subtypes could reactivate p53 and bring about a promising therapeutic strategy in cancers.
