This peptide is amino acids 17 to 26 fragment of p53, the Mdm-2 binding domain of p53 known also as p53N. This sequence contains all of the residues that contact the binding domain of Mdm-2.
Tumor protein p53 binding protein (53BP1) has been identified in a yeast two-hybrid screen as a protein that interacts with the central DNA–binding domain of p532. Similar to breast cancer susceptibility gene 13, 4 (BRCA1; 53BP1 enhances p53-dependent tra
p53 tumor suppressor fragment (232-240) is a peptide with the sequence H2N-Lys-Tyr-Met-Cys-Asn-Ser-Ser-Cys-Met-OH, MW= 1066.3. p53 is a tumor suppressor protein that in humans is encoded by the TP53 gene. p53 is crucial in multicellular organisms, where i
Uncarinic acid E has anti-cancer activity, it induces apoptosis in HepG2 cells via accumulation of p53, alters the Bax Bcl-2 ratio, and activates caspases, resulting in cytochrome c release from the mitochondria. A mixture of uncarinic acid E and 27-O-p-(
YW3-56 is an inhibitor of protein arginine deiminase 2 (PAD2) and PAD4 (IC50s = 0.5-1 and 1-5 μM, respectively).1It inhibits the growth of U2OS osteosarcoma cells (IC50= ~2.5 μM) in a p53-dependent mannerviainduction of SESN2 and subsequent inhibition of mTORC1. YW3-56 (10 mg kg) reduces tumor growth in an S-180 murine sarcoma tumor model. It also inhibits tumor growth in the 1883 MDA-MB-231 breast cancer bone metastasis mouse xenograft model.2 1.Wang, Y., Li, P., Wang, S., et al.Anticancer peptidylarginine deiminase (PAD) inhibitors regulate the autophagy flux and the mammalian target of rapamycin complex 1 activityThe Journal of Biological Chemisty287(31)25941-25952(2012) 2.Wang, S., Chen, X.A., Hu, J., et al.ATF4 gene network mediates cellular response to the anticancer PAD inhibitor YW3-56 in triple-negative breast cancer cellsMol.

p-nitro-Pifithrin-α is a cell-permeable analog of pifithrin-α, a potent p53 inhibitor. It suppresses p53-mediated TGF-β1 expression in HK-2 cells and inhibits the activation of caspase-3 by Zika virus (ZIKV) strains. Moreover, p-nitro-Pifithrin-α attenuates steatosis and liver injury in mice subjected to a high-fat diet, mitigating the effects of non-alcoholic fatty liver disease [1] [2] [3] [4].
