MDM2 protein–protein interaction has been considered as an attractive cancer therapeutic target. More recently developed small molecules exert their effects by interrupting the p53-a href='/search?dc.title=MDM2&facet-content-type=ReferenceWorkEntry&sortOrder=relevance' class='reference-link webtrekk-track' gaCategory="Internal link" gaLabel="MDM2" gaAction="reference keyword">MDM2 binding and enhancing the anti-proliferative activities of p53. Small molecules such as Nutlin, MI-63, MI-219, and MI-319 that can activate p53 have shown their anti-tumor effects in different types of malignancies.
