AZD-1208 is a potent and selective pan-Pim kinase inhibitor which demonstrates efficacy in preclinical models of acute myeloid leukemia. AZD1208 inhibited the growth of 5 of 14 acute myeloid leukemia (AML) cell lines tested, and sensitivity correlates with Pim-1 expression and STAT5 activation. AZD1208 causes cell cycle arrest and apoptosis in MOLM-16 cells, accompanied by a dose-dependent reduction in phosphorylation of Bcl-2 antagonist of cell death, 4EBP1, p70S6K, and S6, as well as increases in cleaved caspase 3 and p27.AZD1208 inhibits the growth of MOLM-16 and KG-1a xenograft tumors in vivo with a clear pharmacodynamic-pharmacokinetic relationship. AZD1208 also potently inhibits colony growth and Pim signaling substrates in primary AML cells from bone marrow that are Flt3 wild-type or Flt3 internal tandem duplication mutant.AZD1208 inhibited tumorigenesis in tissue recombinants, Myc-CaP, and human PC xenograft models.AZD1208 suppressed multiple protumorigenic pathways, including the MYC gene program.

| Method | Cell counting Kit-8 assay | |

| Concentrations | 1 μM | |
| Incubation Time | 48 h | |
| Results | As shown in Figure 1J, AZD1208 and GDC-0941 synergistically reduced viable cell numbers of MV4-11, as judged by combination index (CI) values obtained by the method of Chuo and Talalay being less than 1 at all the concentrations examined. |
| Cell Experiment | |
|---|---|
| Cell lines | EOL-1, KG-1a, Kasumi-3, MV4-11, and MOLM-16 cells |
| Preparation method | For proliferation assays, cells were plated at 5,000 to 20,000 cells per well in 96 well plates overnight before treatment for 72 hours with serially diluted compound or vehicle DMSO. Cell viability was measured after the addition of 10 μL Alamar Blue (Invitrogen) for 4 hours at 37˚C. The GI50 was determined by calculating growth at each dose relative to vehicle treated cells and cell viability at the time of treatment. |

| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| 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.
