Pricing Availability Delivery Time Qty
Cat.No. 4676 - ARRY 520 trifluoroacetate | C20H22F2N4O2S.CF3CO2H | CAS No. 885060-09-3
Description: Potent and selective kinesin spindle protein (KSP) inhibitor; induces Mcl-1 degradation
Alternative Names: Filanesib
Chemical Name: (2S)-2-(3-Aminopropyl)-5-(2,5-difluorophenyl)-N-methoxy-N-methyl-2-phenyl-1,3,4-thiadiazole-3(2H)-carboxamide trifluoroacetate
Purity: ≥98% (HPLC)

Biological Activity

Potent kinesin spindle protein (KSP) inhibitor (IC50 = 6 nM); selective for KSP over >250 other receptors and kinases at a concentration of 10 μM. Displays robust antitumor activity in bortezomib-resistant xenografts either alone or in combination with bortezomib. Induces degradation of Mcl-1; exhibits comparable cytotoxic activity to taxol (Cat. No. 1097) in epithelial ovarian cancer cells. Active in vivo.
