4、OLOGICAL ACTIVITY物活性 ZM-447439是極光激酶 (aurora) 抑制劑，對aurora A和B的 IC50 值分別為110和130 nM。IC50 & Target Aurora A Aurora B110 nM (IC50) 130 nM (IC50)體外研究 Cells treated with ZM-447439 progress through interphase, enter mitosis normally, and assemble bipolarspindles. However, chromosome alignment, segregation,

5、 and cytokinesis all fail. ZM-447439 inhibits celldivision and inhibit mitotic phosphorylation of histone H3. ZM-447439 prevents chromosome alignment andsegregation. ZM-447439 compromises spindle checkpoint function. ZM-447439 inhibits kinetochorelocalization of BubR1, Mad2, and Cenp-E 1. Inhibition

6、 of Aurora kinase by ZM-447439 reduces histone H3phosphorylation at Ser10 in Hep2 carcinoma cells. Multipolar spindles are induced in these ZM-treatedG2/M-arrested cells with accumulation of 4N/8N DNA, similar to cells with genetically suppressed Aurora-B.ZM-447439 treatment induces cell apoptosis.

7、ZM-447439 inhibition of Aurora kinase is potently in associationwith decrease of Akt phosphorylation at Ser473 and its substrates GSK3/ phosphorylation at Ser21 andSer9 2.PROTOCOLKinase Assay 1 1 ng purified recombinant enzyme is added to a reaction cocktail containing buffer, 10 M peptide substrate

8、,10 M for Aurora A or 5 M ATP for Aurora B, and 0.2 Ci 33PATP, and is then incubated at roomtemperature for 60 min. Reactions are stopped by addition of 20% phosphoric acid, and the products arecaptured on P30 nitrocellulose filters and assayed for incorporation of 33P with a Betaplate counter. Noen

9、zyme and no compound control values are used to determine the concentration of ZM-447439, which gave50% inhibition of enzyme activity 1.MCE has not independently confirmed the accuracy of these methods. They are for reference only.Cell Assay 1 To determine cloning efficiency, MCF7 cells are plated i

10、n phenol red free DME plus 5% stripped serum, andare then treated with or without the anti-estrogen ICI 182780 at 1 M for 48 h. ZM-447439 is then added atthe indicated concentrations for 72 h. The cells are harvested, washed, and -400 cells plated in each well of a6-well plate in complete media with

11、out ZM-447439. After 10 d, the colonies are fixed, stained with crystalviolet, and counted. The cloning efficiency represents the number of colonies on ZM-447439-treated platescompared with DMSO-treated controls 1.MCE has not independently confirmed the accuracy of these methods.
