[1980] The crystallographic data of Example 49.2 as well as a figure depicting the thermal ellipsoids and numbering of the structure, are shown in Table 13 and FIG. 6. Colorless crystals of Example 49.2 were obtained by slow evaporation of an ethanol solution. A single crystal was mounted on a cryoloop using a protective oil. Single-crystal X-ray diffraction data were collected at 100 K on a Rigaku XtaLAB Synergy S system with a kappa goniometer and a HyPix-6000HE hybrid photon detector using Cu X-ray radiation (CuKα, =1.54178 Å). Data were integrated using the program CrysAlisPRO. SHELXM was used for structure solution and SHELXL was used for full-matrix least-squares refinement on F2. In the asymmetric unit two molecules of Example 49.2 and two water molecules are present. The di-fluorinated phenyl rings in both molecules are disordered via a 180° rotation of the ring systems. The occupancies for the alternative positions were refined to 0.25/0.75 in Molecule A and 0.35/0.65 in Molecule B, respectively. All non-hydrogen atoms were refined anisotropically. All hydrogen atoms were added in calculated positions and refined riding on their resident atoms. Hydrogens attached to the nitrogen atoms in 49.2 as well as at the water molecules were located in the difference Fourier map and placed manually. The isotropic temperature factors of the hydrogen atoms were refined as 1.2 and 1.5 times the size of the temperature factors of the corresponding heavy atoms, respectively. The absolute stereochemistry (R-configuration) could be assigned unambiguously with a Flack Parameter of 0.008 (7). The program XP was used for molecular representations.

Data were integrated using the program CrysAlisPRO. SHELXM was used for structure solution and SHELXL was used for full-matrix least-squares refinement on F2. In the asymmetric unit four molecules of Example 59.1 and one disordered toluene molecules are present. The fluorinated phenyl ring systems in three of the four molecules are disordered via a 180° rotation of the ring systems. The occupancies for the alternative positions were refined to 0.30/0.70 in Molecule B, 0.20/0.80 in Molecule C and 0.15/0.85 in Molecule D, respectively. The toluene solvent molecule is disordered over a pseudo 2-fold axis and the occupancies for both alternative positions refined with a ratio of 0.45/0.55. All non-hydrogen atoms were refined anisotropically. Hydrogen atoms were added in calculated positions and refined riding on their resident atoms. Hydrogens attached to amine and amide nitrogen atoms were either located in the difference Fourier map and placed manually or were refined using the riding model. The isotropic temperature factors of the hydrogen atoms were refined as 1.2 and 1.5 times the size of the temperature factors of the corresponding heavy atoms, respectively. The absolute stereochemistry (R-configuration) could be assigned unambiguously with a Flack Parameter of 0.015 (11). The program XP was used for molecular representations.

[1985] Examples were tested in selected biological assays one or more times. When tested more than once, data are reported as either average values or as median values, wherein [1986] the average value, also referred to as the arithmetic mean value, represents the sum of the values obtained divided by the number of times tested, and [1987] the median value represents the middle number of the group of values when ranked in ascending or descending order. If the number of values in the data set is odd, the median is the middle value. If the number of values in the data set is even, the median is the arithmetic mean of the two middle values.

[1988] Examples were synthesized one or more times. When synthesized more than once, data from biological assays represent average values or median values calculated utilizing data sets obtained from testing of one or more synthetic batch.

[1989] The in vitro activity of the compounds of the present invention can be demonstrated in the following assays:

[1990] Human DGKζ Kinase Activity Inhibition Assay.

[1991] Human diacylglycerol kinase zeta (DGKζ) inhibitory activity of compounds of the present invention was quantified employing the human DGKζ kinase activity assay as described in the following paragraphs. In essence, the enzyme activity was measured by quantification of the adenosine-di-phosphate (ADP) generated as a co-product of the enzyme reaction via the “ADP-Glo™ Kinase Assay” kit from the company Promega. This detection system works as follows: In a first step the adenosine-tri-phosphate (ATP) not consumed in the kinase reaction is quantitatively converted to cyclic adenosine-mono-phosphate (cAMP) employing an adenylate cyclase (“ADP-Glo-reagent”), then the adenylate cyclase is stopped and the ADP generated in the kinase reaction is converted to ATP, which subsequently generates in a luciferase-based reaction a glow-luminescence signal (“Kinase Detection Reagent”).

[1992] C-terminally FLAG-tagged, recombinant full-length human DGKζ (inhouse expressed in baculovirus infected insect cells, purified using anti-Flag pulldown and size exclusion chromatography) was used as enzyme. As an alternative, commercially available enzyme by Carnabio can be used. As substrate for the kinase, 1,2-dioleoyl-sn-glycerol, reconstituted in octyl-β-D-glucopyranoside micelles, was used. For the preparation of the micelles, 1 volume of a 16.1 mM solution of 1,2-dioleoyl-sn-glycerol (Avanti, Cat. #08001-25G) in chloroform was slowly evaporated using a nitrogen stream. Subsequently, 22.55 volumes of a 510 mM solution of octyl-β-D-glucopyranoside (Sigma-Aldrich, Cat. #08001-10G) in 50 mM MOPS buffer (pH 7.4) were added, and the mixture was sonicated in an ultrasonic bath for 20 s. Then 35 volumes of 50 mM MOPS buffer (pH 7.4) were added to yield a solution of 0.28 mM 1,2 dioleoyl-sn-glycerol and 200 mM octyl-β-D-glucopyranoside, which was aliquoted, flash-frozen in liquid nitrogen, and stored at −20° C. until use. For each experiment, a fresh aliquot was quickly thawed and diluted 24-fold with aqueous assay buffer (described below) containing 95.7 μM adenosine triphosphate (Promega) to yield a 1.67-fold concentrated substrate solution.

[1993] For the assay 50 nl of a 100-fold concentrated solution of the test compound in dimethyl sulfoxide (DMSO, Sigma) was pipetted into either a white 1536-well or a white low-volume 384-well microtiter plate (both Greiner Bio-One, Frickenhausen, Germany). Subsequently, 2 μl of a solution of human DGK; in aqueous assay buffer [50 mM (3-(N-morpholino)propanesulfonic acid (MOPS, pH 7.4, Sigma-Aldrich), 1 mM dithiothreitol (DTT, Sigma-Aldrich), 100 mM NaCl (Sigma-Aldrich), 10 mM MgCl.sub.2 (Sigma-Aldrich), 0.1% (w/v) bovine gamma globulin (BGG, Sigma-Aldrich), 1 μM CaCl.sub.2 (Sigma-Aldrich)] were added to the wells, and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to the enzyme. The reaction was initiated by the addition of 3 μL of substrate solution [preparation described above; 11.7 μM 1,2-dioleoyl-sn-glycerol (=>final conc. in the 5 μL assay volume is 7 μM), 8.33 mM octyl-β-D-glucopyranoside (=>final conc. in 5 μL assay volume is 5 mM), and 91.67 μM adenosine triphosphate (=>final conc. in 5 μL assay volume is 55 μM) in assay buffer] and the resulting mixture was incubated for a reaction time of 20 min at 22° C. The concentration of DGKζ was adjusted depending of the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, a typical concentration is about 0.1 nM. The reaction was stopped by the addition of 2.5 μL of “ADP-Glo-reagent” (1 to 1.5 diluted with water) and the resulting mixture was incubated at 22° C. for 1 h to convert the ATP not consumed in the kinase reaction completely to cAMP. Subsequently 2.5 μl of the “kinase detection reagent” (1.2 fold more concentrated than recommended by the producer) were added, the resulting mixture was incubated at 22° C. for 1 h and then the luminescence measured with a suitable measurement instrument (e.g. Viewlux™ from Perkin-Elmer). The amount of emitted light was taken as a measure for the amount of ADP generated and thereby for the activity of the DGKζ.

[1994] The data were normalised (enzyme reaction without inhibitor=0% inhibition, all other assay components but no enzyme=100% inhibition). Usually the test compounds were tested on the same microtiterplate in 11 different concentrations in the range of 20 μM to 0.07 nM (20 μM, 5.7 μM, 1.6 μM, 0.47 μM, 0.13 μM, 38 nM, 11 nM, 3.1 nM, 0.9 nM, 0.25 nM and 0.07 nM, the dilution series prepared separately before the assay on the level of the 100 fold concentrated solutions in DMSO by serial dilutions, exact concentrations may vary depending pipettors used) in duplicate values for each concentration and IC.sub.50 values were calculated using Genedata Screener™ software.

[1995] Transactivation Assay in Jurkat IL2-Reporter Cell Line

[1996] Transactivation assays were carried out in Jurkat cells purchased from Promega (Promega, #CS187001) stably transfected with a firefly luciferase reporter gene construct under the control of the IL2-promoter. Cells were cultured as specified by the manufacturer. Bulk cells were harvested at a culture density of approx. 1 E+06 cells/mL, suspended in cryo-storage medium (70% RPMI/20% FCS/10% DMSO), frozen at controlled rate of −1°/min in 1.8 mL cryo-vials with cell densities of 1 E+07 to 1 E+08 cells per vial, and stored at −150° C. or below until further use. Frozen cells were thawed and cultured in medium at a starting density of 3.5 E+05 cells/mL for 6 days. On day 6 cells were centrifuged for 5 min at 300×g, medium was decanted and cell concentration was adjusted to 5.0 E+06 cells/mL with fresh assay medium (500 mL RPMI (Gibco, #22400)+5 mL L-Glutamin (Sigma, #G7513)+5 mL Penicillin/Streptomycin (Sigma #P0781)+5 mL Non-essential amino acids (Invitrogen, #11140)+5 mL sodium-pyruvate (Gibco #1136088), 5 mL FBS (Biochrom, #S0615)). Cell working stock was split in two parts: neutral control and compounds with EC30 stimulation, high control with EC100 stimulation.

[1997] An antibody premix was prepared by diluting anti-CD3 (BD Pharmingen, #555329), anti-CD28 (BD Pharmingen, #555725) and goat anti mouse anti-IgG (ThermoFisher, #31160) antibodies at 1/1/4 ratio in assay medium at 2-fold of final concentration (final concentrations depend on cell batch, typically for neutral control 0.055/0.055/0.22 μg/mL, for high control 0.5/0.5/2 mg/mL). The premix solutions were added to the cells in 1+1 volume prior use.

[1998] Fifty nL of a 100-fold concentrated solution of the test compounds in DMSO were transferred into a white microtiter test plate (384, Greiner Bio-One, Germany). For this, either a Hummingbird liquid handler (Digilab, USA) or an Echo acoustic system (Labcyte, USA) was used. Five μL of the freshly prepared cell suspension was added to the wells of a test plate and incubated at 37° C. in a 5% CO.sub.2 atmosphere. After completion of the incubation for 4 hours, 3 μl of Bio-Glo Luciferase assay reagent (Promega, #G7941, prepared as recommended by the supplier) were added to all wells. The test plate was incubated at 20° C. for 10 min before measurement of the luminescence in a microplate reader (typically Pherastar by BMG, Germany, or ViewLux by Perkin-Elmer, USA). Data were normalized (neutral control=0% effect, high control=100% effect). Compounds were tested in duplicates at up to 11 concentrations (typically 20 μM, 5.7 μM, 1.6 μM, 0.47 μM, 0.13 μM, 38 nM, 11 nM, 3.1 nM, 0.89 nM, 0.25 nM and 0,073 nM). Dilution series were made prior to the assay in a 100-fold concentrated form by serial dilution. ECs, values were calculated by 4-Parameter fitting using a commercial software package (Genedata Analyzer, Switzerland).

[1999] Polyclonal Activation of Human PBMCs

[2000] To test the effect of DGKζ inhibitors of the present invention on IL-2 and IFN-γ secretion of human Peripheral Blood Mononuclear Cells (PBMCs) a 24 h human PBMC assay was performed as screening assay. For this, a 96 well flat bottom plate was coated with a suboptimal stimulation condition (EC 10-30) of human aCD3 (Invitrogen, clone OKT3) antibody in 50 μL PBS/well at 4° C. overnight. PBMCs isolated and frozen at liquid N.sub.2 from leucapherese samples was thawed and resuspended in culture medium (X-Vivo-20). 4×10.sup.5 cells/well were plated. Wells were treated with the DGKζ inhibitors of the present invention at the respective concentrations (5-fold dilution steps from 10 μM to 3 nM) and the final DMSO concentration per well is 0.1%. Medium+DMSO (0.1%) was used as baseline value. As positive controls 1000 ng/mL aCD3+aCD28 (1 μg/mL) and a DGKζ reference inhibitor was used. After 24 h the medium was collected and hIL-2 or hIFN-γ ELISA were performed. The following parameters were calculated: EC.sub.50 value, concentration at 50% increase; max increase in % and respective concentration and maximum effect normalized to max concentration (10 μM) of a selected DGKζ reference inhibitor.

[2001] In Vitro Activation of Mouse OT-I Antigen-Specific T-Cells

[2002] To test the effect of DGKζ inhibitors of the present invention in murine antigen-specific T-cells, spleens and lymph nodes of OT-I mice were collected and mashed through a 40 μm cell strainer and incubated for 1 min in 1 mL ACK lysing buffer (Gibco)/spleen. 4×106 cells/mL were incubated in medium containing 0.05 ng/mL SIINFEKL (FIG. 2) in a 50 mL falcon at 37° C. for 30 min. Afterwards cells were centrifuged and 4×106 cells/mL were resuspended in fresh medium (DMEM; 10% FCS, 1% Pen/Strep, 0.1% β-mercaptoethanol, 1% HEPES). 4×105 cells were plated per well in a 96-well round bottom plate. Wells were treated with DGKζ inhibitors of the present invention at the respective concentrations (5-fold dilution steps from 10 μM to 3 nM) in a final DMSO concentration of 0.1%. Medium+DMSO (0.1%) was used as baseline value. As positive controls cells incubated with the 4×SIINFEKL concentration (0.2 ng/ml) and a DGKζ reference inhibitor were used. The plates were centrifuged to reduce the distance between T-cells and APCs before incubation. After 24 h the medium was collected and mIL-2 or mIFN-γ ELISAs were performed. The following parameters were calculated: EC.sub.50 value, concentration at 50% increase; max increase in % and respective concentration and maximum effect normalized to max concentration (10 μM) of a selected DGKζ reference inhibitor.

[2003] DGKζ Surface Plasmon Resonance Interaction Assay

[2004] The ability of the compounds described in this invention to bind to DGKζ were determined using surface plasmon resonance (SPR). This allows for the quantification of binding in terms of the equilibrium dissociation constant (K.sub.D [M]), as well as association and dissociation rate constants (k.sub.on [1/Ms] and k.sub.off [1/s], respectively). The measurements were performed using Biacore® T200, Biacore® S200 or Biacore® 8K (GE Healthcare).

[2005] All buffers described in this section were prepared with 10×HBS-P+ Buffer (GE Healthcare, #BR100671) supplemented with additional buffer components as indicated below, dithiothreitol (DTT from Sigma, #D0632-25G), Adenosine 5′-triphosphate (ATP from Sigma, #A26209-10G), MgCl.sub.2 (Sigma, #M1028-100 ML), dimethyl sulfoxide (DMSO from Biomol, #54686.500).

[2006] For SPR measurements, recombinant and biotinylated human DGKζ (obtained from Carna Biosciences, Product number: 12-410-20N) was immobilized via the streptavidin-biotin interaction onto a Series S Sensor Chip SA (GE Healthcare, #BR-1005-31). Briefly, DGKζ was diluted to a concentration of 10 μg/mL in Immobilization Buffer (10 mM HEPES, 150 mM NaCl, 0.05% v/v Surfactant P20, 2 mM MgCl.sub.2, 1 mM DTT, pH 7.4) and captured on the SA Chip surface using a flow rate of 10 μL/min for 500 seconds at a temperature of 10° C. Immobilization levels of approximately 6000 RU were typically achieved. The reference surface consisted of a streptavidin surface without immobilized protein. Compounds were diluted from 10 mM DMSO stock solution into Running Buffer (10 mM HEPES, 150 mM NaCl, 0.05% v/v Surfactant P20, 2 mM MgCl.sub.2, 1 mM DTT, 0.2 mM ATP and 1% v/v DMSO, pH 7.4). For SPR-binding measurements serial dilutions (typically 1:3 dilutions resulting in 8 concentrations up to 2 μM or 20 μM) were injected over immobilized protein. Binding affinity and kinetics were measured at 18° C. and at a flow rate of 100 μL/min.

[2007] A variation of the assay with an additional regeneration step was performed by injection of Regeneration Buffer without ATP (10 mM HEPES, 150 mM NaCl, 0.05% v/v Surfactant P20, 1 mM DTT and 1% v/v DMSO, pH 7.4) for 200 s at a flow rate of 30 μL/min

[2008] The double-referenced sensorgrams were fit to a simple reversible Langmuir 1:1 reaction mechanism as implemented in the Biacore® T200, S200 and 8K evaluation software (Biacore T200 Evaluation Software version 2.0, Biacore S200 Evaluation Software version 1.0, Biacore 8K Evaluation Software, GE Healthcare).

[2009] Expression of DGKζ in Insect Cells Using the Baculovirus System

[2010] Expression Constructs:

[2011] The cDNA encoding the full length sequence of human DGKζ (Uniprot Q13574-2) was optimized for expression in eukaryotic cells and synthesized by the GeneArt Technology at Life Technologies.

[2012] The DNA sequence encoded the following sequence:

[2013] Construct DGKζ_Hu Amino Acid M1 to V928

[2014] Additionally the expression construct encoded: a Kozak DNA sequence for translation initiation (GCCACC), a translational start codon for methionine followed by amino acid glycine, a Flag (DYKDDDDK) sequence at the N-terminus of DGKζ, and at the C-terminus of DGKζ two stop codons and moreover 5′ and 3′ att-DNA sequences for Gateway Cloning.

[2015] The DGKζ construct was subcloned using the Gateway Technology into the Destination vector pD-INS. The vector pD-INS is a Baculovirus transfer vector (based on vector pVL1393, Pharmingen) which enables the expression of the Flag-DGK) protein. The respective protein was named DGKz_hu_1.

[2016] Generation of Recombinant Baculovirus

[2017] The DGKζ transfer vector was co-transfected in Sf9 cells with Baculovirus DNA (Flashbac Gold DNA, Oxford Expression Technologies) using Fugene HD (Roche). After 5 days the supernatant of the transfected cells containing the recombinant Baculovirus encoding the various DGK proteins was used for further infection of Sf9 cells for virus amplification whereby the virus titer was monitored using qPCR.

[2018] DGKζ Expression in Sf9 Cells Using Bioreactor

[2019] Sf9 cells cultured (Insect-xpress medium, Lonza, 27° C.) in a Wave-bioreactor with a disposable culture bag were infected at a cell density of 10.sup.6 cells/mL with one of the recombinant baculovirus stocks at a multiplicity of infection of 1 and incubated for 72. Subsequently, the cells were harvested by centrifugation (800×g) and the cell pellet frozen at −80° C.

[2020] Purification of the DGKz_Hu_1 Protein:

[2021] Purification of the DGKz_hu_1 protein was achieved by a two-step chromatography procedure as follows.

[2022] The pelleted cells (from 8 L cell culture) were resuspended in Lysis-Buffer (25 mM Tris HCl 80; 500 mM NaCl; 250 mM Sucrose, 1 mM DTT; 0.1% Triton X-100; Complete Protease Inhibitor Cocktail-(Roche)) and lysed by a freeze-thaw cycle followed by an incubation on ice for 60 min in the presence of Benzonase (25 U/mL). The lysate was centrifuged at 63.000×g for 30 min at 4° C. The soluble supernatant was than incubated with 40 mL anti-Flag M2 Agarose (Sigma) in a plastic flask rotating for 16 h at 4° C. for binding of the tagged DGK; proteins, subsequently rinsed with 5×50 mL Wash-Buffer (25 mM Tris HCl 8.0; 500 mM NaCl; 250 mM Sucrose; 1 mM DTT) and finally the bound protein was eluted using Elution-Buffer (Wash-Buffer with 250 μg/mL FLAG-Peptide, incubated 30 min. at 4° C. with 3×25 mL).

[2023] The elution fractions from the affinity chromatography were concentrated (using Amicon Ultra 15, Centrifugal Filters, 30 kDa MW cut-off; Millipore #UFC903024) to 25 mL and applied to a size exclusion chromatography column (S200 prep grade 26/60, GE Healthcare) and the resulting monomeric peak fraction was collected, pooled and again concentrated. Wash-buffer with 300 mM NaCl was used for size exclusion chromatography and the final concentrated sample. The final protein sample concentration was 5 to 10 mg/mL and the yield was 5 mg final protein per L cell culture.

[2024] The in vivo activity of the compounds of the present invention can be demonstrated in the following assays:

[2025] In Vivo Activation of Murine Antigen Specific OT-I T Cells

[2026] Oral Administration of compounds enhances antigen-specific T cell activation in vivo.

[2027] Direct detection of antigen-specific T cell proliferation in vivo is technically challenging, since it requires the presence of T cells specific for a cognate antigen and also a specific measurement procedure for cell proliferation. Both these requirements are fulfilled in the OT-I transfer model, which utilizes the direct transfer of CD8 T cells transgenic for a T cell receptor recognizing an Ovalbumin-derived peptide as antigen.

[2028] Before transfer, the OT-I T cells were labeled with the fluorescent dye CFSE, which was diluted by every cell division and therefore allowed detection of cell proliferation. After transfer of the CFSE-labeled T cells, mice were vaccinated with the Ovalbumin antigen OVA-30 (FIG. 3). Only transferred OT-I cells were able to recognize the OVA-antigen presented by APC and only these transferred T cells then got activated. Flow cytometric analysis of CFSE-levels in the OT-I cells can be combined with measurement of multiple activation markers like CD69, CD25 and PD1. In particular, Wild type C57Bl6 mice received 2×10×6 CFSE-labeled OT-I T cells and were vaccinated one day later by intravenous application of 2.5 μg OVA-30. Mice were then divided into groups which received vehicle only, DGKζ inhibitors of the present invention alone or in combination with other immune modulating agents. Mice were treated for 2 to 20 days and T cell composition (incl. transferred OT-I cells) of spleen, blood and lymph nodes were analysed by FACS.

[2029] In Vivo Syngeneic Tumor Models

[2030] Mice were assigned to a study at the age of 6-8 weeks. Animal husbandry, feeding and health conditions were according to animal welfare guidelines. Syngeneic tumor cell lines were cultivated with appropriate medium and split at least 3 times before inoculation. Female mice were inoculated with appropriate amount of tumor cells in medium or a medium/matrigel mixture s.c, i.v., or i.p, depending on the model. After 4-10 days the mice were randomized and therapeutic treatment started when tumors had reached a size of approx. 40-70 mm.sup.2.

[2031] Tumor size was measured using calipers determining length (a) and width (b). Tumor volume was calculated according to:

v=(a×b{circumflex over ( )}2)/2

[2032] Significance of monotherapies and combination treatment was calculated versus control group as determined by 2-Way ANOVA analysis.
