生物活性 | NSC-87877 is a potent inhibitor ofShp2andShp1protein tyrosine phosphatases(SH-PTP2 and SH-PTP1), withIC50values of 0.318 μM, 0.355 μMshp2and shp1, respectively[1]. NSC-87877 also inhibitsdual-specificityphosphatase26 (DUSP26)[2]. |
IC50& Target | IC50: 0.318 μM (shp2), 0.355 μM (shp1)[1]. |
体外研究 (In Vitro) | NSC-87877 (0-0.5 μM, 5 days) inhibits DUSP26 function in NB cell lines[3]. NSC-87877 (0-0.5 μM, 5 days) results in increased p53 phosphorylation (Ser37 and Ser46) and activation[3].
Cell Viability Assay Cell Line: | p53 wild-type neuroblastoma (NB) cell lines[2]. | Concentration: | 0, 0.25, 0.5 μM. | Incubation Time: | 5 dsys. | Result: | Resulted in increased p53 phosphorylation (Ser37 and Ser46) and activation, increased activation of downstream p38 effector proteins (heat shock protein 27 (HSP27) and MAP kinase-activated protein kinase 2 (MAPKAPK2)) and poly ADP ribose polymerase/caspase-3 cleavage. Inhibited DUSP26 function in NB cell lines. Resulted in apoptosis in many cell lines at varying IC50levels of 1.84 μM (IMR32), 6.35 μM (SK-N-SH), 8.69 μM (NB-19), 12.6 μM (SMS-KCN), 15.7 μM (SH-SY5Y), 15.8 μM (JF) and 19.0 μM (CHLA-225), respectively.
