Pifithrin-α (PFTα) HBr

Pifithrin-α is an inhibitor of p53, inhibiting p53-dependent transactivation of p53-responsive genes.


Cyclic Pifithrin-α hydrobromide

Cyclic Pifithrin-α hydrobromide is the hydrobromide salt form of Cyclic Pifithrin-α, which is a transcriptional inhibitor of p53.



Didymin is a citrus-derived natural compound that kills p53 wild-type as well as drug-resistant p53-mutant neuroblastoma cells in culture. It possesses antioxidant, anti-inflammation and anti-cancer properties.



Pifithrin-μ is a specific p53 inhibitor by reducing its affinity to Bcl-xL and Bcl-2, and also inhibits HSP70 function and autophagy.



NSC348884, as a nucleophosmin inhibitor, inhibit cell proliferation and induce apoptosis in various cancer cell lines with IC50 values ranging from 1.4-4 µM.



ReACp53 is a cell-penetrating peptide, designed to inhibit p53 amyloid formation, resues p53 function in cancer cell lines and in organoids derived from high-grade serous ovarian carcinomas (HGSOC).


JNJ-26854165 (Serdemetan)

JNJ-26854165 (Serdemetan) acts as a HDM2 ubiquitin ligase antagonist and also induces early apoptosis in p53 wild-type cells, inhibits cellular proliferation followed by delayed apoptosis in the absence of functional p53. Phase 1.


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.


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.



Tenovin-1 protects against MDM2-mediated p53 degradation, which involves ubiquitination, and acts through inhibition of protein-deacetylating activities of SirT1 and SirT2.


Kevetrin hydrochloride

Kevetrin hydrochloride is a water-soluble, small molecule and activator of the tumor suppressor protein p53, with potential antineoplastic activity.



PK11007 is an anti-p53 drug that stabilizes wild type and mutant p53 via selective alkylation of two surface-exposed cysteines without compromising its DNA binding activity. It exerts antitumor functions not only via reactivating p53 but also via other cellular mechanisms, such as increase of cellular ROS to toxic levels and activation of the UPR.


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.



COTI-2 is an orally available third generation thiosemicarbazone and activator of mutant forms of the p53 protein, with potential antineoplastic activity.


MI-773 (SAR405838)

MI-773 (SAR405838) is an orally available MDM2 antagonist with Ki of 0.88 nM. Phase 1.



Tenovin-6 is a small molecule activator of p53 transcriptional activity.



APR-246, also known as PRIMA-1MET, is a small organic molecule that has been shown to restore tumour-suppressor function primarily to mutant p53 and also to induce cell death in various cancer types.



NSC59984 is a p53 pathway activator via induction of mutant p53 protein degradation and p73 activation.


CBL0137 (CBL-0137)

CBL0137(CBL-0137) activates p53 and inhibits NF-kB with EC50s of 0.37 μM and 0.47 μM in the cell-based p53 and NF-kB reporter assays, respectively. It also inhibits histone chaperone FACT (facilitates chromatin transcription complex).



PRIMA-1 is a mutant p53 reactivator. It induces apoptosis and inhibits growth of human tumors with mutant p53.



(-)-Parthenolide, an inhibitor of the Nuclear Factor-κB Pathway, specifically depletes HDAC1 protein without affecting other class I/II HDACs; Also promotes the ubiquitination of MDM2 and activates p53 cellular functions.
