Sulanemadlin

**Semantic type:** Pharmacologic Substance

**Definition:** An orally available peptide inhibitor of both murine double minute 2 (MDM2) and murine double minute X (MDMX), with potential antineoplastic activity. Upon oral administration, sulanemadlin binds to both MDM2 and MDMX and interferes with their interaction with the transcriptional activation domain of the tumor suppressor protein p53. By preventing MDM2-p53 and MDMX-p53 interactions, p53 activity is restored, which leads to p53-mediated induction of tumor cell apoptosis. MDM2 and MDMX, negative regulators of p53 function, are often overexpressed in cancer cells.

**Synonyms:** - ALRN-6924 - MDM2/MDMX Inhibitor ALRN-6924 - SULANEMADLIN
