General description
A cell-permeable thiazolidinone compound that inhibits actin assembly mediated by actin-related protein Arp2/3 complex of human and bovine, but not yeast, species (IC50 = 11 µM against bovine Arp2/3). Shown to inhibit the actin filament "comet tails" formation around intracellular Listeria in infected SKOV3 cells (IC50 = 7 µM). Structrual studies indicate that CK-869 targets the hydrophobic core in subdomain 1 of Arp3. CK-666 (Cat. No. 182515) and CK-869 exhibit different modes of binding, resulting in their different yeast cross-reactivities. Supplied as a racemic mixture of the active 2S and the inactive 2R enantiomers. CK-312 (Cat. No. 182518 ) can serve as a negative control.
Preparation Note
