NSC697923

Research use only, not for human use.

NSC697923 (NSC 697923) is a small molecule that specifically inhibits the activity of the ubiquitin-conjugating (E2) enzyme Ubc13 (UBE2N)-Uev1A.

NSC697923 (NSC 697923) is a small molecule that specifically inhibits the activity of the ubiquitin-conjugating (E2) enzyme Ubc13 (UBE2N)-Uev1A; NSC697923 impedes the formation of the Ubc13 and ubiquitin thioester conjugate and suppresses constitutive NF-κB activity in ABC-DLBCL cells, inhibits NF-κB activation induced by PMA, but not by TNFα; specifically inhibits Ubc13-mediated polyubiquitin chain synthesis in vitro, does not inhibits UbcH5c-mediated polyubiquitin chain formation; inhibits the proliferation and survival of ABC-DLBCL cells and GCB-DLBCL cells.

Cell Viability Assay 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 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.

Animal Model:5- to 6-week-old female athymic Ncr nude mice (orthotopic mouse model of NB; SH-SY5Y and NGP xenografts) Dosage:5?mg/kg Administration:I.p.; daily for 10 days Result:Significant tumor regression in both SH-SY5Y and NGP xenografts.
