SAB Comments

I would like to see a more comprehensive screen of this probe against more than 50 kinases to confirm its broad selectivity. IC50 is listed at 0.37 nM. It is ~3700-fold more selective for Aurora B over Aurora A. AZD1152-HQPA is the active metabolite of AZ1152.

AZD1152 is a phosphate pro-drug that is rapidly cleaved to the active alcohol. The active alcohol is a potent inhibitor of AURB and AURC. We have dosed AZD1152 in tumor xenograft models in mice using IP administration (100 mg/kg, dosed once daily for 3 consecutive days) and seen robust efficacy in sensitive models (e.g., Lymphoma DOOH2 cell line). The AZD1152 alcohol is significantly less active in P-gp- and BCRP-expressing cell lines, most likely due to drug efflux.

AZD1152 is a phosphate prodrug designed for in vivo studies only. The active form is compound 34 in the corresponding J Med Chem paper, with Aurora B inhibition IC50 <1 nM and the corresponding functional effect in SW620 cells of IC50 17 nM. For in vitro, cell-based studies, Compound 34 should be used since cleavage of the phosphate in AZD1152 might not occur in a cellular system. The compound is very selective based on profiling in the Ambit kinome panel where less than 10 kinases (example EPHB6, FLT3 (more potent than Aurora B)), have a KD within 10X of that for Aurora B. Any kinase reported as an off target within 100X could have functional effect in cellular environment if the Km for ATP is large.
