1 A novel mechanism of irinotecan targeting MDM2 and Bcl-xL. Irinotecan BCL2 like 1 Homo sapiens
2 In this study, we present a new mechanism of Irinotecan which inhibits the activities of MDM2, an E3 ligase of tumour suppressor p53, and Bcl-xL, an anti-apoptotic protein, through direct binding. Irinotecan BCL2 like 1 Homo sapiens
3 In our structure modelling study, Irinotecan could fit to the binding sites of MDM2 and Bcl-xL for their known drugs, Nutlin-3 and ABT-737, with a better binding affinity than to Topo I. Irinotecan BCL2 like 1 Homo sapiens
4 We further showed that Irinotecan increased the amount of p53 only in the presence of MDM2 and inhibited the physical interaction of Bcl-xL with Bim, a core pro-apoptotic protein. Irinotecan BCL2 like 1 Homo sapiens
5 Collectively, we suggest a new mechanism of action for Irinotecan as a dual target inhibitor of MDM2 and Bcl-xL facilitating the anticancer activities mediated by p53 and Bcl-xL interaction partners. Irinotecan BCL2 like 1 Homo sapiens
6 Collectively, we suggest a new mechanism of action for Irinotecan as a dual target inhibitor of MDM2 and Bcl-xL facilitating the anticancer activities mediated by p53 and Bcl-xL interaction partners. Irinotecan BCL2 like 1 Homo sapiens
