生物活性

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

IC50 & Target[1][2]

HSP70

 

MDM-2/p53

 

體外研究
(In Vitro)

Pifithrin-μ (10 μM) is a p53 inhibitor, which inhibits p53 binding to mitochondria by reducing its affinity to antiapoptotic proteins Bcl-xL and Bcl-2 but has no effect on p53-dependent transactivation, activity of caspases 2, 8, 9 and 10 in a cell-free system, or NF-κB-dependent transcription[1]. Pifithrin-μ (PES) time- and dose-dependently reduces viability in A549 cells, with IC50s of 44.9 and 25.7 μM at 24 h and 48 h. Pifithrin-μ (20 μM) suppresses the cell migration, induces cell cycle arrest and cell apoptosis in A549 and H460 cells. Pifithrin-μ (10 or 20 μM) inhibits activities of AKT, ERK, and Hsp70 in A549 and H460 cells. Pifithrin-μ (20 μM) sensitizes A549 and H460 cell lines to TRAIL-induced cell proliferation inhibition and apoptosis[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內(nèi)研究
(In Vivo)

Pifithrin-μ (40 mg/kg, i.p.) shows no protective effect against doses of radiation that cause gastrointestinal syndrome in mice[1]. Pifithrin-μ (PES, 10 mg/kg) shows antitumor effect in mice bearing A549 cells[2]. Pifithrin-μ exhibits neuroprotective effect with the P53-inhibitor pifithrin-μ after cardiac arrest in a rodent model[3].

Cell Assay
[2]

The cell viability is determined by the Cell Counting Kit-8 assay. Briefly, A549 and H460 cells are incubated in 96-well plates at a density of 5 × 103 per 100 μL of culture medium overnight. After treated with indicated concentration of Pifithrin-μ for 24 and 48 h, 10 μL of tetrazolium substrate are added to each well of the plate. After incubation at 37°C for 1 h, the absorbance is recorded at a wavelength of 450 nm using a microplate reader. Each experiment is determined in triplicate and repeated at least three times[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[2]

Mice[2]
A549 cells (1 × 107) are suspended in Matrigel and inoculated subcutaneously into the mice. Twelve mice bearing evident tumors are arbitrarily assigned to PBS control group and Pifithrin-μ treatment groups (six mice per group). When tumors reach a size of ~5×5 mm2, mice are treated with either a single of intraperitoneal injection of Pifithrin-μ (20 mg/kg) or PBS every two days. After 3-week treatment, mice are euthanized with carbon dioxide. Tumor burdens are evaluated by measuring body weight, tumor weight, and tumor volume. Tumor volume is determined as 0.5 × length × width2. Tumor samples are collected and fixed in 10% neutral buffered formalin. Hematoxylin and eosin staining and immunohistochemistry for histological analysis of tumor samples are measured[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
