INTERMEDIATES

[0825] ##STR00024##

[0826] Method A: General Procedure for the Preparation of Intermediates of Formula (I) by Reductive Amination

[0827] The reaction is typically performed by combining an appropriate alkyl, cycloalkyl, substituted cycloalkyl or heteroaryl amine of formula R1-NH.sub.2 (1-1.2 equiv.) and a carbonyl compound (aldehyde or methyl-ketone) (0.67-3 equiv.) in the presence of an appropriate base (typically, trimethylamine or sodium acetate), or without a presence of base, and acetic acid (1-3 equiv.) or pTsOH×H.sub.2O or without addition of acetic acid or pTsOH×H.sub.2O in a suitable solvent (typically, methanol or toluene or dichloromethane) in the presence or without molecular sieves or magnesium perchlorate (0.3 equiv.) or sodium sulphate or magnesium sulphate. The resulting mixture is stirred at 0° C. to room temperature to 110° C. for 2 h to 5 days. To the reaction temperature lowered to 0° C. or at room temperature, a reducing agent (1.2-16 equiv.) is added (typically, sodium borohydride or sodium cyanoborohydride or lithium borohydride). The resulting mixture is stirred at room temperature for 1-72 hours. The expected Intermediate of formula (I) may be isolated and, if desired, further purified by methods known to one skilled in the art.

[0828] Alternatively, a mixture of alkyl, cycloalkyl, substituted cycloalkyl or heterocyclic amine (R1-NH.sub.2) (1-1.2 equiv.), a carbonyl compound (0.8-2 equiv.), an appropriate base (typically, trimethylamine), or without a presence of base, and Lewis acid (2.1-2.4 equiv.) (typically, Ti(iPrO).sub.4) in an appropriate solvent, such as dichloromethane, is stirred at room temperature for 12-20 hours or under microwave irradiation at 70° C. for 15 minutes. The reaction mixture is evaporated till dryness, dissolved in an appropriate solvent, such as methanol, and then a reducing agent, such as sodium borohydride, (2-5 equiv.) is added portionwise to give the corresponding intermediate of formula (I), which is isolated and, if desired, may be further purified by methods known to one skilled in the art.

Biological Assays

Example 1—Effect of Compounds on Tryptophan Catabolism in SK-OV-3 Cell Line

[0927] SK-OV-3 cells are seeded in 96-well plates in McCoy's 5A medium supplemented with 10% FBS and incubated overnight at 37° C., 5% CO2, 95% humidity. The next 5 day growth medium is replaced with DMEM F-12 medium supplemented with 6 mg/mL L-tryptophan. Compounds are added to the wells and incubated for 24 h at 37° C., 5% CO2, 95% humidity. Compounds are tested at 8 consecutive 3-fold dilutions starting from 30 μM in duplicate.

[0928] At the end of incubation, concentration of kynurenine in cell supernatants is 10 determined by LC-MS/MS. In parallel, cell viability is assessed by measurement of ATP using CellTiter Glo assay (Promega), according to manufacturer's protocol.

[0929] Inhibition of Kyn production is calculated using the following formula:

[00001] ( 1 - Kyn conc . cmpd . - Kyn conc . medium Kyn conc . medium with cells - Kyn conc . medium ) .Math. 100

[0930] IC50 values are determined using GraphPad Prism software 5.04 for Windows by plotting percent of inhibition against log 10 concentrations of compounds using a four-parametric sigmoidal curve with a variable slope.

[0931] Cell viability results are analysed in Microsoft Excel and expressed as fold change over untreated control.

[0932] IC50 ranges for compounds of the invention are presented in Table 2, whereby the IC50 ranges are as follows: [0933] A: IC.sub.50<100 nM [0934] B: IC.sub.50=100-500 [0935] C: IC.sub.50=500-1000 nM [0936] D: IC.sub.50=1000-5000 nM [0937] E: IC.sub.50>5000 nM

Example 4—Effect of Compounds on IDO1 Expression in SK-OV-3 Cell Line

[0942] SK-OV-3 cells are seeded in 24-well plates in McCoy's 5A medium supplemented with 10% FBS at density of 250000 cells per well and incubated overnight at 37° C., 5% CO2, 95% humidity. The following day growth medium is replaced with DMEM F-12 medium containing 6 mg/mL L-tryptophan. Compounds are added to the wells and the plate is incubated for 24 h at 37° C., 5% CO2, 95% humidity. At the end of incubation medium is removed, cells are washed and then lysed in RIPA buffer. Protein concentrations in the samples are determined using BCA method (Thermo Scientific) and adjusted to 0.5 mg/mL. Western analysis is performed on the Wes system (Protein Simple) using IDO1 (Cell Signalling; Cat #12006S) and GAPDH (Abcam, Cat #ab9485) antibodies. Expression of IDO1 is normalised to GAPDH.

Example 5—Effect of Compounds on Tryptophan Catabolism in Monocyte-Derived Dendritic Cells

[0943] Peripheral blood mononuclear cells are isolated from buffy coats from healthy volunteers by Lymphoprep density gradient centrifugation, followed by lysis of residual erythrocytes with isotonic buffer solution of ammonium chloride. CD14+ cells are isolated by positive selection using MACS® technology and CD14 MicroBeads (Miltenyi Biotec) according to manufacturer's instructions. The isolated monocytes are differentiated into dendritic cells by incubation for 5 days in RPMI-1640 medium supplemented with 10% fetal bovine serum (FBS), 50 ng/mL GM-CSF and 35 ng/mL IL-4. After 5 days the DCs are seeded in 96-well plates in DMEM supplemented with 10% charcoal stripped FBS, GM-CSF and IL-4. The following day cells are triggered with LPS and IFNγ. After 24 h of incubation medium is replaced with DMEM F-12 medium supplemented with 6 mg/mL L-tryptophan and 10% charcoal stripped FBS. Compounds are added to the cells and incubated for 24 h at 37° C., 5% CO2, 95% humidity. Compounds are tested at 7 consecutive 4-fold dilutions starting from 30 μM in duplicate.

[0944] At the end of incubation concentration of kynurenine in cell supernatants is determined by LC-MS/MS. In parallel, cell viability is assessed by measurement of ATP by use of CellTiter Glo assay (Promega) according to manufacturer's protocol.

[0945] Inhibition of Kyn production is calculated using the following formula:


(1−(Kyn conc. cmpd.−Kyn conc. medium)/(Kyn conc. medium with cells−Kyn conc. medium)).Math.100

[0946] IC50 values are determined using GraphPad Prism software 5.04 for Windows, by plotting percent of inhibition against log 10 concentrations of compounds using a four-parametric sigmoidal curve with a variable slope.

[0947] Cell viability results are analysed in Microsoft Excel and expressed as fold change over untreated control.

Example 6—Tumour Cell Killing Assay

[0948] Human PBMCs from healthy donors are prepared from buffy coat and cryopreserved. For the killing assay, on day −1, NucLight™ Red transfected SK-OV-3 ovarian cancer cells are seeded in to a Flat-bottomed 96-well plate at 2×103 cells/well (100 μL per well) and incubated in the Incucyte Zoom® overnight. The following day (day 0) media is aspirated from wells containing SK-OV-3 cells. Caspase 3/7 reagent (1:2000) is prepared and added to wells at 50 μL per well, together with 50 μL test substances. Anti-CD3, (final concentration 0.1 μg/mL), anti-CD28 (final concentration 0.5 μg/mL) and rhIL-2 (final concentration 10 ng/mL) are prepared in complete media and added in a final volume of 50 μL per well. Untouched PBMCs are prepared from cryopreserved stock and added to wells at 1×104 cells per well in a volume of 50 μL per well, such that the final well volume is 200 μL. Cells are incubated/monitored in the Incucyte Zoom® for a period of seven days.

[0949] Wells are imaged at 3-hour intervals in phase, green and red channels. Automated image analysis enables selective quantitation of SK-OV-3 nuclei (Red) per well, apoptotic SK-OV-3 nuclei (Green/Red colocalised) to enable the effect of test substance on apoptosis to be determined and quantified graphically over time.
