Background:

AZD1152 is a highly selective inhibitor of Aurora kinases with IC50 values of 1.37 μM and 0.37 nM for Aurora A and Aurora B, respectively [1].
AZD1152 is a dihydrogen phosphate pro-drug of HQPA which is a highly potent and specific inhibitor of the serine/threonine kinase Aurora kinases. The expression of Aurora kinase A and B are found to be related with the development of various cancers such as ovarian, pancreatic, breast and colon. Since that, the Aurora family is regarded as attractive target for anticancer treatment. As a selective Aurora kinase inhibitor, AZD1152 showed no significant effect on other kinases including JAK2, FLT3 and Abl. Besides that, AZD1152 exerted potent antitumor activities through inhibiting tumor cell proliferation and inducing apoptosis [1].
AZD1152 treatment potently inhibited cell growth in various leukemic cells including ALL PALL-2, MV4-11 and MOLM13 with IC50 values of 5, 1and 2.8 nM, respectively. AZD1152 also inhibited clone formation of freshly isolated leukemia cells with IC50 values of less than 3 nM. For the colon cancer HCT-116 cells, incubation of AZD1152 at dose of 30 nM for one day resulted in 80% cell number reduction after 4 days drug wash out. In prostate cancer DU145 and PC3 cells, AZD1152 caused decrease of G0/G1-phase cells and induced G2/M cell cycle arrest. Moreover, AZD1152 treatment enhanced the radio sensitivity of prostate cancer cells which were androgen-insensitive [1, 2 and 3].
In mice model with human MOLM13 cell xenografts, administration of AZD1152 at dose of 25 mg/kg significantly inhibited tumor growth. The combination treatment of AZD1152 at dose of 5 mg/kg and vincristine at dose of 0.2 mg/kg resulted in almost 100% inhibition of tumor growth of MOLM13 xenografts. In mice injected with MiaPaCa-2cells, the combination of AZD1152 and gemcitabine showed more than double effective than the single treatment [1 and 2].
