Description

Description générale

A cell-permeable quinazoline-thione compound that acts as a potent, specific, and reversible inhibitor of the microtubule-stimulated ATPase activity of the mitotic motor, Eg5 (IC₅₀ = 200 nM). Exhibits little effect on the ATPase activity of kinesin-1, -4, -7 and -10 and is ~100-fold more potent than Monastrol (Cat. No. 475879). Also inhibits bipolar spindle formation in both HeLa cells and in Xenopus egg extracts and induces cell cycle arrest (~1 µM). Shown to induce mitotic arrest and apoptosis and upregulate Hsp70 in human multiple myeloma cells.
