Description: CX-6258 is a pan-Pim kinases inhibitor with excellent biochemical potency and kinase selectivity. CX-6258 exhibited in vitro synergy with chemotherapeutics and robust in vivo efficacy in two Pim kinases driven tumor models. Inhibition of Pim kinases is expected to have a beneficial effect as cancer therapy.

| Biological target: | CX-6258 is a potent and kinase selective pan-Pim kinases inhibitor, with IC50s of 5 nM, 25 nM and 16 nM for Pim-1, Pim-2 and Pim-3, respectively. |
| In vitro activity: | CX-6258 shows antiproliferative activity against a panel of human cancer cell lines with IC50 of 0.02-3.7 μM, mostly sensitive to acute leukemia cell lines. Combinations of CX-6258 with doxorubicin (10:1 molar ratio) and CX-6258 with paclitaxel (100:1 molar ratio) produces synergistic cell killing with combination index (CI50) values equal to 0.4 and 0.56, respectively. CX-6258 causes dose dependent inhibition of the phosphorylation of two pro-survival proteins, Bad and 4E-BP1, at the Pim kinase specific sites S112 and S65 and T37/46, respectively.

| In vivo activity: | In an in vivo setting, analogue CX-6258 was evaluated in two human tumor xenograft growth efficacy models, acute myeloid leukemia MV-4-11, and prostate adenocarcinoma PC3. These particular models were selected because of the important roles that Pim kinases were shown to play in both diseases. Mice carrying MV-4-11 xenografts were administered a single oral dose daily. The drug exhibited dose dependent efficacy, with a 50 mg/kg dose producing 45% tumor growth inhibition (TGI) and a 100 mg/kg dose producing 75% TGI (Figure 4). Compound 13 was well tolerated throughout the study. Treatment of mice carrying PC3 xenografts once daily with a 50 mg/kg oral dose of CX-6258 was also well tolerated and produced 51% TGI (Supporting Information).
