442633-00-3Cc1[nH]c2ccccc2c1CCNC(=O)c1ccccc1FUXRKUKRXVWJFER-UHFFFAOYSA-NCK-666 is a member of the class of indoles that is 2-methyltryptamine in which a hydrogen attached to the primary amino group has been replaced by a 2-fluorobenzoyl group. It is a cell-permeable inhibitor of actin assembly mediated by actin-related protein Arp2/3 complex which works by binding to Arp2/3 complex, stabilising the inactive state of the complex and preventing its movement into the active conformation. It has a role as an actin polymerisation inhibitor. It is a member of benzamides, a member of indoles and an organofluorine compound.

용도CK-666 may be used to study Arp2/3-mediated structural changes in cells.
일반 설명A cell-permeable indolyl-fluorobenzamide compound that selectively inhibits actin assembly mediated by actin-related protein Arp2/3 complex of human, bovine, fission yeast S. pombe, and budding yeast S. cerevisiae origin (IC50 = 4, 17, 5, and 12 μM, respectively), without affecting S. pombe formin domain Cdc12(FH2)-mediated or the spontaneous actin polymerization. Shown to inhibit the actin filament "comet tails" formation around intracellular Listeria in infected SKOV3 cells (IC50 = 7 μM) in a reversible manner. Structrual studies indicate that CK-666 targets a pocket formed between subdomain 4 of Arp2 and subdomain 1 of Arp3, preventing Arp2/3 from shifting into an active conformation upon N-WASP-VCA binding. CK-666 and CK-869 (Cat. No. 182516) exhibit different modes of binding, resulting in their different yeast cross-reactivities. CK-689 (Cat. No. 182517) can serve as a negative control.
