Description: MI-773, also known as SAR405838, is an orally available spiro-oxindole HDM2 (human double minute 2) antagonist with potential antineoplastic activity. Upon oral administration, the p53-HDM2 protein-protein interaction inhibitor MI-773 binds to HDM2, preventing the binding of the HDM2 protein to the transcriptional activation domain of the tumor suppressor protein p53. By preventing this HDM2-p53 interaction, the proteosome-mediated enzymatic degradation of p53 is inhibited and the transcriptional activity of p53 is restored, which may result in the restoration of p53 signaling and lead to the p53-mediated induction of tumor cell apoptosis. HDM2, a zinc finger protein and a negative regulator of the p53 pathway, is often overexpressed in cancer cells. It has been implicated in cancer cell proliferation and survival. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
