Product Description
Potent, cell permeable cysteine thioether displaying anti-mitotic and anti-tumor properties. Inhibits mitosis by blocking basal and microtubule-activated ATPase activities of the mitotic kinesin Eg5 (IC50=1µM and 140nm). Induces mitotic arrest in HeLa cells (IC50=700nM) and inhibits the growth of NCI tumor cell line panel (GI50=1.31µM).

Product Description
Antibiotic. Is ~10-fold more potent than cytochalasin B (Prod. No. ALX-380-012) in inhibiting actin filament function, but does not inhibit sugar transport in cells. Inactivates low conductance K+ channels. Modulates CD4 cross-linking in T-lymphocytes and increases intracellular Ca2+ levels. Exhibits antitumor activity. Induces apoptosis.
