S2678 NSC 207895 NSC 207895 suppresses MDMX with IC50 of 2.5 μM, leading to enhanced p53 stabilization/activation and DNA damage, and also regulates MDM2, an E3 ligase.
S2781 RITA (NSC 652287) RITA (NSC 652287) induces both DNA-protein and DNA-DNA cross-links with no detectable DNA single-strand breaks, and also inhibits MDM2-p53 interaction by targeting p53.

S8000 Tenovin-1 Tenovin-1 protects against MDM2-mediated p53 degradation, which involves ubiquitination, and acts through inhibition of protein-deacetylating activities of SirT1 and SirT2.
S7649 MI-773 (SAR405838) MI-773 (SAR405838) is an orally available MDM2 antagonist with Ki of 0.88 nM. Phase 1.
S7149 NSC 319726 NSC319726 is a p53(R175) mutant reactivator, exhibits growth inhibition in cells expressing mutant p53, with IC50 of 8 nM for p53(R175) mutant, shows no inhibition for p53 wild-type cells.
S2930 Pifithrin-μ Pifithrin-μ is a specific p53 inhibitor by reducing its affinity to Bcl-xL and Bcl-2, and also inhibits HSP70 function and autophagy.
  • Biochim Biophys Acta, 2014, 1842(11):2204-15
S4900 Tenovin-6 Tenovin-6 is a small molecule activator of p53 transcriptional activity.
