NSC697923 Usage And Synthesis

Description

NSC-69723 (343351-67-7) is a selective inhibitor of the E2 ubiquitin-conjugating enzyme, Ubc13-Uev1A. Does not inhibit UbcH5c activity. Impedes the formation of the Ubc13 and inhibits NF-κB activation in activated B cell-like diffuse large B-cell lymphoma (ABC-DLBCL) cells.1?Blocks proliferation and survival of both ABC-DLBCL and germinal center B cell-like (GCB)-DLBCL cell lines, and survival of primary DLBCL cells. NSC-69723 acts via covalent bonding to E2 active site thiol.2,3?Induces neuroblastoma cell death via activation of p53 and JNK.4

Uses

NSC 697923 is a cell-permeable and selective inhibitor of the ubiquitin-conjugating (E2) enzyme Ubc13-Uev1A and exhibits potent cytotoxicity in a panel of Neuroblastoma (NB) cell lines. NSC 697923 also inhibits the proliferation and survival of diffuse large B-cell lymphoma cells (DLBCL).
