CW069 is an allosteric inhibitor of HSET with IC50 of 75 μM, it showed marked activity against HSET in vitro. CW069 therefore constitutes a valuable tool for probing HSET function and, by reducing the growth of cells containing supernumerary centrosomes, paves the way for new cancer therapeutics. CW-069 potently suppresses N1E-115 cells, and less potently inhibits the NHDF cells, with IC50 of 86 ± 10 μM and 181 ± 7 μM, respectively. CW-069 (100 or 200 μM) causes increased multipolar spindles in N1E-115 cells with supernumerary centrosomes and shows no effect on altering bipolar spindle morphology in normal human dermal fibroblast cells. CW-069 (200 μM) cacuses multipolar anaphase and cell death induced in N1E-115 cells via transfection with HSET siRNA, and antagonizes inhibition of KSP by monastrol, but does not exert mitotic arrest in HeLa cells.

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
