The invention relates to chemical compounds of formula I,
and salts thereof. In some embodiments, the invention relates to inhibitors or modulators of PIM-1 and/or PIM-2, and/or PIM-3 protein kinase activity or enzyme function. In still further embodiments, the invention relates to pharmaceutical compositions comprising compounds disclosed herein, and their use in the prevention and treatment of PIM kinase related conditions and diseases, preferably cancer.
PIM-1 gene was first identified as a proviral insertion site in Moloney murine leukemia virus-induced T-cell lymphoma. PIM-1 gene translates a Ser/Thr protein kinase. The known PIM kinase family also includes PIM-2 and PIM-3. Mice studies suggest that physiologically the PIM kinases are involved in growth factor and cytokine signaling. Deregulated PIM kinase expression occurs a in large number of hematopoietic tumors, such as myeloid and lymphoblastic leukemias and lyphomas. PIM kinases are also expressed in solid tumors, such as prostate cancer and pancreatic cancer, and transgenic mice which express PIM-1 develop T-cell lymphoma. Dhanasekaran et al., (2001). Nature 412: 822-826 and Li et al., (2006) Cancer Res 66: 6741-6747. Accordingly, it is believed that PIM Kinase inhibitors will be useful in the treatment and/or prevention of cancer. Thus, there is a need to identify inhibitors of PIM kinases.

The tablets can be coated by methods well known in the art. Liquid preparations for oral administration can take the form of, for example, solutions, syrups or suspensions, or they can be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations can be prepared by conventional means with pharmaceutically acceptable additives such as suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid).

A mixture of (R)-tert-butyl 1-(2-bromo-6-formylphenyl)piperidin-3-yl carbamate (Method 95) (300 mg, 0.78 mmol), phenylboronic acid (143 mg, 1.17 mmol), 1,1′-bis(di-tert-butyllphosphino)ferrocenedichloro palladium (II) complex (40.8 mg, 0.06 mmol), and Na2CO3 (124 mg, 1.17 mmol) was suspended in dioxane (5 mL) and water (1.50 mL) and stirred at 110° C. for overnight under an atmosphere of nitrogen. The reaction was cooled to rt and water (˜50 mL) and ethyl acetate (˜50 mL) was added to the mixture. The organic phase was separated, dried over anhydrous MgSO4, filtered, and conc. in vacuo affording a residue purified with via silica gel chromatography (40 g) using a gradient of 5% to 30% ethyl acetate/hexanes to yield the title compound as a low melting solid (168 mg, 56.4%); m/z 381.
One may purify examples provided above by reverse-phase HPLC in a solvent contain varying concentrations of trifluoroacetic acid or hydrochloric acid. Thus the examples above may be isolated as, the freebase, hydrochloride salt, or trifluoroacetate salt.
PIM 1 and 2 enzyme assay descriptions:
One may determine the activity of purified human His-PIM1 [2-313] enzyme in-vitro using a mobility shift assay on a Caliper LC3000 reader (Caliper, Mass.), which measures fluorescence of a phosphorylated and unphosphorylated FL-Ahx-Bad (FITC-(AHX)RSRHSSYPAGT-COOH, Primm 200606-00289, Primm Biotech, MA) and calculates a ratiometric value to determine percent turnover. One may express PIM1 (University of Dundee, Scotland) in baculovirus system with a typical yield of >85% purity.
One determines phosphorylation of the FL-Ahx-Bad in the presence and absence of the compound of interest. One preincubates 5 ul of Enzyme/Substrate/adenosine triphosphate (ATP) mix consisting of 2.4 nM PIM1, 3.6 uM FL-Ahx-Bad, and 240 uM ATP in 1.2× buffer with 2 ul of compound for 20 minutes at 25° C. One initiates reactions with 5 ul of Metal mix consisting of 24 mM MgCl2 in 1.2× buffer and incubated at 25° C. for 90 minutes and stops the reactions by addition of 5 ul of Stop mix consisting of 100 mM HEPES, 121 mM ethylenediamine tetraacetic acid, 0.8% Coatin Reagent 3 (Caliper, Mass.), and 0.01% Tween. One detects phosphorylated and unphosphorylated substrate by a Caliper LC3000 reader (Caliper, Mass.) in the presence of separation buffer consisting of 100 mM HEPES, 16 mM ethylenediamine tetraacetic acid, 0.1% Coatin Reagent 3 (Caliper, Mass.), 0.015% Brij-35, 5% DMSO, and 5.6 mM MgCl2. One may use the following separation conditions for a Caliper LC3000: −1.0 PSI, −2000 V upstream voltage, −400 V downstream voltage, 0.2 second sample sip, 45 second post sip, 10% laser strength.
One may determine the activity of purified human His-PIM2 [23-299] enzyme in-vitro using a mobility shift assay on a Caliper LC3000 reader (Caliper, Mass.), which measures fluorescence of a phosphorylated and unphosphorylated FL-Ahx-Bad (FITC-(AHX)RSRHSSYPAGT-COOH, Primm 200606-00289, Primm Biotech, MA) and calculates a ratiometric value to determine percent turnover. One may express PIM2 (produced at AstraZeneca, R&D Boston) in E. coli cells with a typical yield of >90% purity.

Using the above described assays, or appropriate modifications thereof, preferred compounds disclosed herein generally have an IC50 for PIM1 of less that 5 micromolar (uM), and even more preferred of less than 1 micromolar. The table 1 below provides the percent inhibition of PIM1 at 0.3 micromolar for Examples provided herein. Several examples were tested more than once. Variations in the experimental outcomes, negative values, or values over 100% inhibition are presumably due to experimental error inherent in the assay.
