| 生物活性 | NSC697923 is a potentUBE2N(ubiquitin-conjugating enzyme E2 N, Ubc13) inhibitor. NSC697923 induces neuroblastoma (NB) cell death via promoting nuclear importation of p53 in p53 wild-type NB cells. NSC697923 also induces cell death in p53 mutant NB cells by activation of JNK-mediated apoptotic pathway. NSC697923 inhibits DNA damage andNF-κBsignaling. Antitumor activity[1][2]. |
体外研究
(In Vitro) | NSC697923 (0-5 μM; 24 hours) shows cytotoxic effect on NB cell lines[1].
NSC697923 (3 μM; 2 hours) can also induce apoptosis in p53 mutant NB cells by activation of JNK-mediated apoptotic pathway[1].
NSC697923 induces apoptosis in p53 wild-type NB cell lines by promoting p53 nuclear translocation and activation[1].
Cell Viability Assay[1] | Cell Line: | Three MYCN-amplified cell lines: IMR32, NGP, NB19 and three MYCN-non-amplified cell lines: CHLA-255, SK-N-AS, and SH-SY5Y | | Concentration: | 0-5 μM | | Incubation Time: | 24 hours | | Result: | Significantly reduced NB cells viability in a dose-dependent manner. Also induced cell death in the p53 non-functional cell line SK-N-AS and p53 partially functional cell line NB-19. |
Western Blot Analysis[1] | Cell Line: | p53 wild-type SH-SY5Y and IMR32 cells | | Concentration: | 3 μM | | Incubation Time: | 2 hours | | Result: | Induced expression of p53-targeted gene p21 as well as the cleavage of caspase 3 in two p53 wild-type cell lines SH-SY5Y and IMR32. |
