MDM-2/p53 p53 Inhibitor

Pifithrin-α hydrobromide is a p53 inhibitor which blocks its transcriptional activity and prevents cells from apoptosis. Pifithrin-α hydrobromide is also an aryl hydrocarbon receptor (AhR) agonist.

Pifithrin-μ is an inhibitor of p53 and HSP70, with antitumor and neuroprotective activity.

Pifithrin-α, p-Nitro, Cyclic (PFN-α) is cell-permeable and active-form p53 inhibitor. Pifithrin-α, p-Nitro, Cyclic is one order magnitude more active than Pifithrin-α in protecting cortical neurons exposed to Etoposide (ED₅₀=30 nM). Pifithrin-α, p-Nitro, Cyclic behaves as a p53 posttranscriptional activity inhibitor. Pifithrin-α, p-Nitro, Cyclic do not prevent p53 phosphorylation on the S15 residue.

Pifithrin-β hydrobromide (PFT β hydrobromide) is a potent p53 inhibitor with an IC₅₀ of 23 μM.

Pseudoginsenoside F11 is an orally active neuroprotective agent. Pseudoginsenoside F11 reduces the expression of β-amyloid precursor protein, inhibits the production of Aβ_1-40, downregulates the expression of JNK2, p53 and activated Caspase 3, and restores the activities of SOD and Glutathione peroxidase. Pseudoginsenoside F11 inhibits the excessive activation of μ-Calpain and restores the level of neuronal Nitric oxide synthase. Pseudoginsenoside F11 reduces infarct volume, alleviates cerebral edema, decreases neuronal loss, improves neurological deficits and enhances long-term functional outcomes in transient cerebral ischemia models. Pseudoginsenoside F11 antagonizes Methamphetamine-induced behavioral deficits, dopamine level reduction and neurotoxicity without altering the baseline behaviors of normal mice. Pseudoginsenoside F11 can be used in studies related to Alzheimer's disease, transient cerebral ischemic injury and Methamphetamine-induced neurotoxicity.

NSC194598 is a p53 DNA-binding inhibitor with an IC₅₀ value of 180 nM. NSC194598 inhibits p53 DNA binding and induction of target genesn when p53 is stabilized and activated by irradiation or chemotherapy. NSC194598 can interfere with transcriptional activation of mutated rearranged during transfection (RET) gene, induce apoptosis and G0/G1 phase arrest. NSC194598 can be used for the researches of acute radiation toxicity and medullary thyroid carcinoma.

P53R3 is a potent p53 reactivator and restores sequence-specific DNA binding of p53 hot spot mutants, including p53^R175H, p53^R248W and p53^R273H. P53R3 induces p53-dependent antiproliferative effects with much higher specificity than PRIMA-1. P53R3 enhances the recruitment of wild-type p53 and p53^M237I to several target gene promoters. P53R3 strongly enhances the mRNA, total protein and cell surface expression of the death receptor death receptor 5 (DR5). P53R3 is used for cancer research.

Teprasiran (QPI-1002) is a small interfering RNA that temporarily inhibits p53-mediated cell death that underlies acute kidney injury (AKI).

Quinovic acid is triterpene. Quinovic acid can ameliorate the Amyloid-β burden, p53 expression and cholesterol accumulation by deterring the oxidative stress through upregulating the Nrf2/HO-1 pathway. Quinovic acid can induce cancer cells apoptosis by upregulating death receptor 5 (DR5). Quinovic acid can be used for the researches of cancer, inflammation, metabolic and neurological disease, such as lung cancer and Alzheimer’s disease (AD).

p-nitro-Pifithrin-α, a cell-permeable analog of pifithrin-α, is a potent p53 inhibitor. p-nitro-Pifithrin-α suppresses p53-mediated TGF-β1 expression in HK-2 cells. p-nitro-Pifithrin-α inhibits the activation of caspase-3 by Zika virus (ZIKV) strains. p-nitro-Pifithrin-α attenuates steatosis and liver injury in mice fed a high-fat diet [4]. non-alcoholic fatty liver disease.

Altissimacoumarin F (Compound 4) is a terpenylated coumarin. Altissimacoumarin F can be isolated from the stem bark of Ailanthus altissima. Altissimacoumarin F enhances SIRT1 activity, decreases p53 transcriptional activity. Altissimacoumarin F can be used for the research of age-related disorders.

MS7972 is a small molecule that blocks human p53 and CREB binding protein association. MS7972 can almost completely block this BRD interaction at 50 μM.

Pifithrin-μ (Standard) is the analytical standard of Pifithrin-μ. This product is intended for research and analytical applications. Pifithrin-μ is an inhibitor of p53 and HSP70, with antitumor and neuroprotective activity.

Pifithrin-α (hydrobromide) (Standard) is the analytical standard of Pifithrin-α (hydrobromide). This product is intended for research and analytical applications. Pifithrin-α hydrobromide is a p53 inhibitor which blocks its transcriptional activity and prevents cells from apoptosis. Pifithrin-α hydrobromide is also an aryl hydrocarbon receptor (AhR) agonist.

Pifithrin-β (PFT β) is a potent p53 inhibitor with an IC₅₀ of 23 μM.
