    Product Description

    Eg5-I is a potent inhibitor of Eg5, both in vitro and in cells (IC50s = 127 and 190 nM, respectively).1 It is an analog of S-trityl-L-cysteine (STLC), but is more potent and has better solubility than STLC. Eg5-I blocks bipolar spindle formation and inhibits the growth of cancer cells, with an average GI50 value of 360 nM against a broad panel of tumor cells (GI50 range = 10 nM to 3 µM).1 It ranges from 140- to 1200-fold more potent against cancer cells than monastrol (Item No. 15044), which also acts by inhibiting Eg5.2,1
