     BACKGROUND 
     Diacylglycerol kinases (DGKs) represent a family of enzymes that catalyze phosphorylation of the membrane lipid sn-1,2 diacylglycerol (DAG) to form phosphatidic acid (PA) (T. O. Eichmann and A. Lass, Cell. Mol. Life Sci. 2015, 72, 3931-3952). In T cells, DAG is formed downstream of the T cell receptor (TCR) after activation of the gamma 1 isoform of phospholipase C (PLCγ1) and cleavage of phosphatidylinositol 4,5-biphosphate (PIP2) into DAG and an additional second messenger, inositol 1,4,5-triphosphate (IP3) (S. Krishna and X. P. Zhong, Front. Immunol. 2013, 4, 178). Whereas, IP3 is important in facilitating release of calcium from the endoplasmic reticulum, DAG interacts with other proteins important in TCR signal transduction, such as Protein kinase Cθ (E. J. Quann et al., Nat. Immunol. 2011, 12 (7), 647-654) and the Ras activating protein RasGRP1 (S. Krishna and X. P. Zhong, Front. Immunol. 2013, 4, 178). Although, three isoforms of DGKζ are known to be present within T cells [DGKα (DGKalpha), DGKδ (DGKdelta), and DGKζ (DGKzeta)], only two, DGKα and DGKζ, are thought to play an important role in facilitating DAG metabolism downstream of the TCR (R. P. Joshi and G. A. Koretzky, Int. J. Mol. Sci. 2013, 14 (4), 6649-6673). 
     Targeting the activity of DGKζ in T cells, either by germline deletion, or with chemical inhibitors, results in enhanced and sustained signaling downstream of T cells, as assessed by prolonged phosphorylation of downstream molecules, such as extracellular signal-related kinases 1/2 (ERK1/2) and NFκB (X. P. Zhong et al., Nat. Immunol. 2003, 4, 882-890; B. A. Olenchock et al., Nat. Immunol. 2006, 7 (11), 1174-1181; M. J. Riese et al., J. Biol. Chem. 2011, 286, 5254-5265; E. M. Wesley et al., ImmunoHorizons 2018, 2 (4), 107-118). 
     Deletion of DGKζ in T cells leads to enhanced production of effector cytokines, such as IL2, IFNγ and enhanced proliferation (X. P. Zhong et al., Nat. Immunol. 2003, 4, 882-890; B. A. Olenchock et al., Nat. Immunol. 2006, 7 (11), 1174-1181, E. M. Riese et al., J. Biol. Chem. 2011, 286, 5254-5264). 
     Adoptive transfer of DGK; deficient T cell reduced leukaemia burden after inoculation of C1498. SIY leukaemia cells compared to control. Also, DGKζ deficient T cells are at least partially resistant to PD1 mediated inhibitory signals (W. Jing et al., Cancer Res. 2017, 77 (20), 5676-5686). In addition, DGKζ deficient mice have reduced tumor sizes compared to control after orthotopic tumor injection of a pancreatic tumor model (E. M. Wesley et al., ImmunoHorizons, 2018, 2 (4), 107-118). Also, S. Wee et al. inoculated C57BL/6 mice with a variety of syngeneic tumor cell lines—MC38 colon carcinoma, B16F1 melanoma, and C1498 leukemia—and analysed survival and tumor growth between mice deficient in DGKζ in the presence or absence of anti-PD1 treatment. DGKζ−/− mice suppressed growth of subcutaneously implanted tumor cells in the three model systems and the combination of DGKζ-deficiency and anti-PD1 was additive in tumor control (S. Wee et al., Proceedings of the American Association for Cancer Research Annual Meeting 2019; Cancer Res. 2019, 79 (13 Suppl): Abstract nr 936). 
     These findings suggest that DGKζ might serve as a useful target for enhancing T cell anti-tumor activity. 
     Additionally, the adoptive transfer of CAR (chimeric antigen receptor)-T cells deficient in DGKζ demonstrated increased efficacy compared to wild type CAR T cells in the treatment of murine mesothelioma (M. J. Riese et al., Cancer Res. 2013, 73 (12), 3566-3577) and a glioblastoma xenograft mouse model in combination with DGKα knockout (I. Y. Jung et al., Cancer Res. 2018, 78 (16), 4692-4703). 
     Also, DGKζ-deficient mice mounted a more robust immune response to lymphocytic choriomeningitis virus infection than did wild-type mice (X. P. Zhong et al., Nat. Immunol. 2003, 4, 882-890). 
     DGKζ is also relevant in natural killer (NK) cells. Upon stimulation through multiple activating receptors, NK cells from mice lacking DGKζ display increased cytokine production and degranulation in an ERK-dependent manner. Additionally, they have improved cytotoxic functions against tumor cell lines. (E. Yang et al. J. Immunol. 2016, 197(3), 934-41.) Apart from immune-cell regulation, DGKα also plays a role in cancer, mediating numerous aspects of cancer cell progression including proliferation, apoptosis, survival, invasion and tumorigenicity, e.g. in osteosarcoma, colon cancer, breast cancer, prostate cancer, glioma and leukemia models (W. Yu et al., Front. Oncol. 2019, 8:655; K. Cai et al., BMC Cancer 2014, 14:208; J. Diao et al., Mol. Neurobiol. 2016; 53, 5425-35; H. Li et al. Pharmazie 2019, 74(7): 418-422). 
     In addition, DGKζ knock-out diminished both airway inflammation and airway hyperresponsiveness in mice and also reduced bronchoconstriction of human airway samples in vitro by blocking T helper 2 (TH2) differentiation (B. A. Singh et al., Sci. Signal. 2019, 12: eaax3332). 
     Taken together, the findings from these studies argue that restraining DGKζ activity in T cells and tumor cells may prove valuable in generating more vigorous immune responses against pathogens and tumors and in ameliorating Th2 driven (auto-) immune diseases (in re-balancing the immune-system). 
     Furthermore, inhibition of DGKα has the potential to reverse the life-threatening Epstein-Barr virus (EBV)-associated immunopathology that occurs in X-linked lymphoproliferative disease (XLP-1) patients (E. Ruffo et al., Sci. Transl. Med. 2016, 8: (321):321ra7; S. Velnati et al., Eur. J. Med. Chem. 2019, 164, 378-390). Based on the underlying mode of action, it can be assumed that inhibition of DGKζ would have a similar effect. 
     The DGKα-inhibitor II (R59949) could suppress retinal neovascularization and protect retinal astrocytes in an Oxygen-Induced Retinopathy Model (L. Yang et al., J. Mol. Neurosci. 2015, 56, 78-88). Also, based on the underlying mode of action, it can be assumed that inhibition of DGK; would have a similar effect. 
     In a DGKζ knock-out mouse it was shown that DGKζ deficiency increases protection against insulin resistance (B. Benziane et al., J. Lipid Res. 2017, 58 (12), 2324-2333). 
     In summary, inhibiting DGKζ activity has a therapeutic potential in targeting tumors directly as well as addressing virus infections, lymphoproliferative disorders, asthma, eye diseases, and type 2 diabetes/insulin resistance.

     Definitions 
     The term “substituted” means that one or more hydrogen atoms on the designated atom or group are replaced with a selection from the indicated group, provided that the designated atom&#39;s normal valency under the existing circumstances is not exceeded. Combinations of substituents and/or variables are permissible. 
     The term “optionally substituted” means that the number of substituents can be equal to or different from zero. Unless otherwise indicated, it is possible that optionally substituted groups are substituted with as many optional substituents as can be accommodated by replacing a hydrogen atom with a non-hydrogen substituent on any available carbon or nitrogen atom. Commonly, it is possible for the number of optional substituents, when present, to be 1, 2, 3 or 4, in particular 1, 2 or 3. 
     When groups in the compounds according to the invention are substituted, it is possible for said groups to be mono-substituted or poly-substituted with substituent(s), unless otherwise specified. Within the scope of the present invention, the meanings of all groups which occur repeatedly are independent from one another. It is possible that groups in the compounds according to the invention are substituted with one, two or three identical or different substituents, particularly with one substituent. 
     As used herein, an oxo substituent represents an oxygen atom, which is bound to a carbon atom or to a sulfur atom via a double bond. 
     Should a composite substituent be composed of more than one part, e.g. (C 1 -C 2 -alkoxy)-(C 1 -C 6 -alkyl)-, it is possible for a given part to be attached at any suitable position of said composite substituent, e.g. it is possible for the C 1 -C 2 -alkoxy part to be attached to any suitable carbon atom of the C 1 -C 5 -alkyl part of said (C 1 -C 2 -alkoxy)-(C 1 -C 6 -alkyl)-group. A hyphen at the beginning or at the end of such a composite substituent indicates the point of attachment of said composite substituent to the rest of the molecule. Should a ring, comprising carbon atoms and optionally one or more heteroatoms, such as nitrogen, oxygen or sulfur atoms for example, be substituted with a substituent, it is possible for said substituent to be bound at any suitable position of said ring, be it bound to a suitable carbon atom and/or to a suitable heteroatom.

Said bridged heterocycloalkyl group is, for example, azabicyclo[2.2.1]heptyl, oxazabicyclo[2.2.1]heptyl, thiazabicyclo[2.2.1]heptyl, diazabicyclo[2.2.1]heptyl, azabicyclo[2.2.2]octyl, diazabicyclo[2.2.2]octyl, oxazabicyclo[2.2.2]octyl, thiazabicyclo[2.2.2]octyl, azabicyclo[3.2.1]octyl, diazabicyclo[3.2.1]octyl, oxazabicyclo[3.2.1]octyl, thiazabicyclo[3.2.1]octyl, azabicyclo[3.3.1]nonyl, diazabicyclo[3.3.1]nonyl, oxazabicyclo[3.3.1]nonyl, thiazabicyclo[3.3.1]nonyl, azabicyclo[4.2.1]nonyl, diazabicyclo[4.2.1]nonyl, oxazabicyclo[4.2.1]nonyl, thiazabicyclo[4.2.1]nonyl, azabicyclo[3.3.2]decyl, diazabicyclo[3.3.2]decyl, oxazabicyclo[3.3.2]decyl, thiazabicyclo[3.3.2]decyl or azabicyclo[4.2.2]decyl.       

     The term “bicyclic nitrogen containing 5-11 membered heterocycloalkyl” means a 5-11 membered heterospirocycloalkyl, 5-11 membered fused heterocycloalkyl or 5-11 membered bridged heterocycloalkyl group as defined supra, however containing one ring nitrogen atom and optionally one or two further ring heteroatoms from the series N, O and S; it being possible for said bicyclic nitrogen containing 5-11 membered heterocycloalkyl group to be attached to the rest of the molecule via a nitrogen atom or any one of the carbon atoms, except a spiro carbon atom. 
     The term “heteroaryl” means a monovalent, monocyclic or bicyclic aromatic ring having 5, 6, 8, 9 or 10 ring atoms (a “5- to 10-membered heteroaryl” group), which contains at least one ring heteroatom and optionally one, two or three further ring heteroatoms from the series: N, O and/or S, and which is bound via a ring carbon atom, or, if valency allows as e.g. in pyrrol-1-yl, a nitrogen atom. 
     Said heteroaryl group can be a 5-membered heteroaryl group, such as, for example, thienyl, furanyl, pyrrolyl, oxazolyl, thiazolyl, imidazolyl, pyrazolyl, isoxazolyl, isothiazolyl, oxadiazolyl, triazolyl, thiadiazolyl or tetrazolyl; or a 6-membered heteroaryl group, such as, for example, pyridinyl (herein also referred to as pyridyl), pyridazinyl, pyrimidinyl, pyrazinyl or triazinyl; or a 9-membered heteroaryl group, such as, for example, benzofuranyl, benzothienyl, benzoxazolyl, benzisoxazolyl, benzimidazolyl, benzothiazolyl, benzotriazolyl, thiazolopyridinyl, indazolyl, indolyl, isoindolyl, indolizinyl or purinyl; or a 10-membered heteroaryl group, such as, for example, quinolinyl, quinazolinyl, isoquinolinyl, cinnolinyl, phthalazinyl, quinoxalinyl or pteridinyl. In general, and unless otherwise mentioned, the heteroaryl or heteroarylene groups include all possible isomeric forms thereof, e.g.: tautomers and positional isomers with respect to the point of linkage to the rest of the molecule. Thus, for some illustrative non-restricting examples, the term pyridinyl includes pyridin-2-yl, pyridin-3-yl and pyridin-4-yl; or the term thienyl includes thien-2-yl and thien-3-yl. 
     The term “C 1 -C 6 ”, as used in the present text, e.g. in the context of the definition of “C 1 -C 6 -alkyl”, “C 1 -C 6 -haloalkyl”, “C 1 -C 6 -hydroxyalkyl”, “C 1 -C 6 -alkoxy” or “C 1 -C 6 -haloalkoxy” means an alkyl group having a finite number of carbon atoms of 1 to 6, i.e. 1, 2, 3, 4, 5 or 6 carbon atoms.

     As used herein, the term “leaving group” means an atom or a group of atoms that is displaced in a chemical reaction as stable species taking with it the bonding electrons. In particular, such a leaving group is selected from the group comprising: a halogen atom, in particular a fluorine atom, a chlorine atom, a bromine atom or an iodide atom, being displaced as halide, in particular fluoride, chloride, bromide or iodide; (methylsulfonyl)oxy, [(trifluoromethyl)sulfonyl]oxy, [(nonafluorobutyl)sulfonyl]oxy, (phenylsulfonyl)oxy, [(4-methylphenyl)sulfonyl]oxy, [(4-bromophenyl)sulfonyl]oxy, [(4-nitrophenyl)sulfonyl]oxy, [(2-nitrophenyl)sulfonyl]oxy, [(4-isopropylphenyl)sulfonyl]oxy, [(2,4,6-triisopropylphenyl)sulfonyl]oxy, [(2,4,6-trimethylphenyl)sulfonyl]oxy, [(4-tert-butylphenyl)sulfonyl]oxy and [(4-methoxyphenyl)sulfonyl]oxy.

     Particularly, said dipolar aprotic solvent is acetonitrile, dimethylsulfoxide, N,N-dimethylformamide, N,N-dimethylacetamide or 1-methyl-2-pyrrolidinone. 
     As used herein, the term “room temperature” means a temperature in the range from 15° C. to 25° C. 
     It is possible for the compounds of general formula (I) to exist as isotopic variants. The invention therefore includes one or more isotopic variant(s) of the compounds of general formula (I), particularly deuterium-containing compounds of general formula (I). 
     The term “Isotopic variant” of a compound or a reagent is defined as a compound exhibiting an unnatural proportion of one or more of the isotopes that constitute such a compound. 
     The term “Isotopic variant of the compound of general formula (I)” is defined as a compound of general formula (I) exhibiting an unnatural proportion of one or more of the isotopes that constitute such a compound. 
     The expression “unnatural proportion” means a proportion of such isotope which is higher than its natural abundance. The natural abundances of isotopes to be applied in this context are described in “Isotopic Compositions of the Elements 1997”, Pure Appl. Chem., 70(1), 217-235, 1998. 
     Examples of such isotopes include stable and radioactive isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, bromine and iodine, such as  2 H (deuterium),  3 H (tritium),  11 C,  13 C,  14 C,  15 N,  17 O,  18 O,  32 P,  33 P,  33 S,  34 S,  35 S,  36 S,  18 F,  36 Cl,  82 Br,  123 I,  124 I,  125 I,  129 I and  131 I, respectively. 
     With respect to the treatment and/or prophylaxis of the disorders specified herein the isotopic variant(s) of the compounds of general formula (I) preferably contain deuterium (“deuterium-containing compounds of general formula (I)”). Isotopic variants of the compounds of general formula (I) in which one or more radioactive isotopes, such as  3 H or  14 C, are incorporated are useful e.g. in drug and/or substrate tissue distribution studies. These isotopes are particularly preferred for the ease of their incorporation and detectability. Positron emitting isotopes such as  18 F or  11 C may be incorporated into a compound of general formula (I). These isotopic variants of the compounds of general formula (I) are useful for in vivo imaging applications. Deuterium-containing and  13 C-containing compounds of general formula (I) can be used in mass spectrometry analyses in the context of preclinical or clinical studies. 
     Isotopic variants of the compounds of general formula (I) can generally be prepared by methods known to a person skilled in the art, such as those described in the schemes and/or examples herein, by substituting a reagent for an isotopic variant of said reagent, preferably for a deuterium-containing reagent. Depending on the desired sites of deuteration, in some cases deuterium from D 2 O can be incorporated either directly into the compounds or into reagents that are useful for synthesizing such compounds. Deuterium gas is also a useful reagent for incorporating deuterium into molecules. Catalytic deuteration of olefinic bonds and acetylenic bonds is a rapid route for incorporation of deuterium. Metal catalysts (i.e. Pd, Pt, and Rh) in the presence of deuterium gas can be used to directly exchange deuterium for hydrogen in functional groups containing hydrocarbons. A variety of deuterated reagents and synthetic building blocks are commercially available from companies such as for example C/D/N Isotopes, Quebec, Canada; Cambridge Isotope Laboratories Inc., Andover, Mass., USA; and CombiPhos Catalysts, Inc., Princeton, N.J., USA. 
     The term “deuterium-containing compound of general formula (I)” is defined as a compound of general formula (I), in which one or more hydrogen atom(s) is/are replaced by one or more deuterium atom(s) and in which the abundance of deuterium at each deuterated position of the compound of general formula (I) is higher than the natural abundance of deuterium, which is about 0.015%. Particularly, in a deuterium-containing compound of general formula (I) the abundance of deuterium at each deuterated position of the compound of general formula (I) is higher than 10%, 20%, 30%, 40%, 50%, 60%, 70% or 80%, preferably higher than 90%, 95%, 96% or 97%, even more preferably higher than 98% or 99% at said position(s). It is understood that the abundance of deuterium at each deuterated position is independent of the abundance of deuterium at other deuterated position(s). 
     The selective incorporation of one or more deuterium atom(s) into a compound of general formula (I) may alter the physicochemical properties (such as for example acidity [C. L. Perrin, et al., J. Am. Chem. Soc., 2007, 129, 4490], basicity [C. L. Perrin et al., J. Am. Chem. Soc., 2005, 127, 9641], lipophilicity [B. Testa et al., Int. J. Pharm., 1984, 19(3), 271]) and/or the metabolic profile of the molecule and may result in changes in the ratio of parent compound to metabolites or in the amounts of metabolites formed. Such changes may result in certain therapeutic advantages and hence may be preferred in some circumstances. Reduced rates of metabolism and metabolic switching, where the ratio of metabolites is changed, have been reported (A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). These changes in the exposure to parent drug and metabolites can have important consequences with respect to the pharmacodynamics, tolerability and efficacy of a deuterium-containing compound of general formula (I). In some cases deuterium substitution reduces or eliminates the formation of an undesired or toxic metabolite and enhances the formation of a desired metabolite (e.g. Nevirapine: A. M. Sharma et al., Chem. Res. Toxicol., 2013, 26, 410; Efavirenz: A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). In other cases the major effect of deuteration is to reduce the rate of systemic clearance. As a result, the biological half-life of the compound is increased. The potential clinical benefits would include the ability to maintain similar systemic exposure with decreased peak levels and increased trough levels. This could result in lower side effects and enhanced efficacy, depending on the particular compound&#39;s pharmacokinetic/pharmacodynamic relationship. ML-337 (C. J. Wenthur et al., J. Med. Chem., 2013, 56, 5208) and Odanacatib (K. Kassahun et al., WO2012/112363) are examples for this deuterium effect. Still other cases have been reported in which reduced rates of metabolism result in an increase in exposure of the drug without changing the rate of systemic clearance (e.g. Rofecoxib: F. Schneider et al., Arzneim. Forsch./Drug. Res., 2006, 56, 295; Telaprevir: F. Maltais et al., J. Med. Chem., 2009, 52, 7993). Deuterated drugs showing this effect may have reduced dosing requirements (e.g. lower number of doses or lower dosage to achieve the desired effect) and/or may produce lower metabolite loads. 
     A compound of general formula (I) may have multiple potential sites of attack for metabolism. To optimize the above-described effects on physicochemical properties and metabolic profile, deuterium-containing compounds of general formula (I) having a certain pattern of one or more deuterium-hydrogen exchange(s) can be selected. Particularly, the deuterium atom(s) of deuterium-containing compound(s) of general formula (I) is/are attached to a carbon atom and/or is/are located at those positions of the compound of general formula (I), which are sites of attack for metabolizing enzymes such as e.g. cytochrome P 450 . 
     In another embodiment the present invention concerns a deuterium-containing compound of general formula (I) having 1, 2, 3 or 4 deuterium atoms, particularly with 1, 2 or 3 deuterium atoms. 
     Where the plural form of the word compounds, salts, polymorphs, hydrates, solvates and the like, is used herein, this is taken to mean also a single compound, salt, polymorph, isomer, hydrate, solvate or the like. 
     By “stable compound” or “stable structure” is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. 
     The compounds of the present invention optionally contain one or more asymmetric centres, depending upon the location and nature of the various substituents desired. It is possible that one or more asymmetric carbon atoms are present in the (R) or (S) configuration, which can result in racemic mixtures in the case of a single asymmetric centre, and in diastereomeric mixtures in the case of multiple asymmetric centres. In certain instances, it is possible that asymmetry also be present due to restricted rotation about a given bond, for example, the central bond adjoining two substituted aromatic rings of the specified compounds. 
     Preferred isomers are those which produce the more desirable biological activity. These separated, pure or partially purified isomers or racemic mixtures of the compounds of this invention are also included within the scope of the present invention. The purification and the separation of such materials can be accomplished by standard techniques known in the art. 
     The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example, by the formation of diastereoisomeric salts using an optically active acid or base or formation of covalent diastereomers. Examples of appropriate acids are tartaric, diacetyltartaric, ditoluoyltartaric and camphorsulfonic acid. Mixtures of diastereoisomers can be separated into their individual diastereomers on the basis of their physical and/or chemical differences by methods known in the art, for example, by chromatography or fractional crystallisation. The optically active bases or acids are then liberated from the separated diastereomeric salts. A different process for separation of optical isomers involves the use of chiral chromatography (e.g., HPLC columns using a chiral phase), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable HPLC columns using a chiral phase are commercially available, such as those manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ, for example, among many others, which are all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of the present invention can likewise be obtained by chiral syntheses utilizing optically active starting materials. 
     In order to distinguish different types of isomers from each other reference is made to IUPAC Rules Section E (Pure Appl Chem 45, 11-30, 1976). 
     The present invention includes all possible stereoisomers of the compounds of the present invention as single stereoisomers, or as any mixture of said stereoisomers, e.g. (R)- or (S)-isomers, in any ratio. Isolation of a single stereoisomer, e.g. a single enantiomer or a single diastereomer, of a compound of the present invention is achieved by any suitable state of the art method, such as chromatography, especially chiral chromatography, for example. 
     Further, it is possible for some of the compounds of the present invention to exist as tautomers. For example, the compounds of the present invention may contain a pyridone moiety and can exist as a pyridone, or as an hydroxypyridine, or even a mixture in any amount of the two tautomers, namely: 
     
       
         
         
             
             
         
       
     
     The present invention includes all possible tautomers of the compounds of the present invention as single tautomers, or as any mixture of said tautomers, in any ratio. 
     Further, the compounds of the present invention can exist as N-oxides, which are defined in that at least one nitrogen of the compounds of the present invention is oxidised. The present invention includes all such possible N-oxides. 
     The present invention also covers useful forms of the compounds of the present invention, such as metabolites, hydrates, solvates, prodrugs, salts, in particular pharmaceutically acceptable salts, and/or co-precipitates. 
     The compounds of the present invention can exist as a hydrate, or as a solvate, wherein the compounds of the present invention contain polar solvents, in particular water, methanol or ethanol for example, as structural element of the crystal lattice of the compounds. It is possible for the amount of polar solvents, in particular water, to exist in a stoichiometric or non-stoichiometric ratio. In the case of stoichiometric solvates, e.g. a hydrate, hemi-, (semi-), mono-, sesqui-, di-, tri-, tetra-, penta- etc. solvates or hydrates, respectively, are possible. The present invention includes all such hydrates or solvates. 
     Further, it is possible for the compounds of the present invention to exist in free form, e.g. as a free base, or as a free acid, or as a zwitterion, or to exist in the form of a salt. Said salt may be any salt, either an organic or inorganic addition salt, particularly any pharmaceutically acceptable organic or inorganic addition salt, which is customarily used in pharmacy, or which is used, for example, for isolating or purifying the compounds of the present invention. The term “pharmaceutically acceptable salt” refers to an inorganic or organic acid addition salt of a compound of the present invention. For example, see S. M. Berge et al., “Pharmaceutical Salts,” J. Pharm. Sci. 1977, 66, 1-19. 
     A suitable pharmaceutically acceptable salt of the compounds of the present invention may be, for example, an acid-addition salt of a compound of the present invention bearing a nitrogen atom, in a chain or in a ring, for example, which is sufficiently basic, such as an acid-addition salt with an inorganic acid, or “mineral acid”, such as hydrochloric, hydrobromic, hydroiodic, sulfuric, sulfamic, bisulfuric, phosphoric, or nitric acid, for example, or with an organic acid, such as formic, acetic, acetoacetic, pyruvic, trifluoroacetic, propionic, butyric, hexanoic, heptanoic, undecanoic, lauric, benzoic, salicylic, 2-(4-hydroxybenzoyl)-benzoic, camphoric, cinnamic, cyclopentanepropionic, digluconic, 3-hydroxy-2-naphthoic, nicotinic, pamoic, pectinic, 3-phenylpropionic, pivalic, 2-hydroxyethanesulfonic, itaconic, trifluoromethanesulfonic, dodecylsulfuric, ethanesulfonic, benzenesulfonic, para-toluenesulfonic, methanesulfonic, 2-naphthalenesulfonic, naphthalenedisulfonic, camphorsulfonic acid, citric, tartaric, stearic, lactic, oxalic, malonic, succinic, malic, adipic, alginic, maleic, fumaric, D-gluconic, mandelic, ascorbic, glucoheptanoic, glycerophosphoric, aspartic, sulfosalicylic, or thiocyanic acid, for example. 
     Further, another suitably pharmaceutically acceptable salt of a compound of the present invention which is sufficiently acidic, is an alkali metal salt, for example a sodium or potassium salt, an alkaline earth metal salt, for example a calcium, magnesium or strontium salt, or an aluminium or a zinc salt, or an ammonium salt derived from ammonia or from an organic primary, secondary or tertiary amine having 1 to 20 carbon atoms, such as ethylamine, diethylamine, triethylamine, ethyldiisopropylamine, monoethanolamine, diethanolamine, triethanolamine, dicyclohexylamine, dimethylaminoethanol, diethylaminoethanol, tris(hydroxymethyl)aminomethane, procaine, dibenzylamine, N-methylmorpholine, arginine, lysine, 1,2-ethylenediamine, N-methylpiperidine, N-methyl-glucamine, N,N-dimethyl-glucamine, N-ethyl-glucamine, 1,6-hexanediamine, glucosamine, sarcosine, serinol, 2-amino-1,3-propanediol, 3-amino-1,2-propanediol, 4-amino-1,2,3-butanetriol, or a salt with a quaternary ammonium ion having 1 to 20 carbon atoms, such as tetramethylammonium, tetraethylammonium, tetra(n-propyl)ammonium, tetra(n-butyl)ammonium, N-benzyl-N,N,N-trimethylammonium, choline or benzalkonium. 
     Those skilled in the art will further recognise that it is possible for acid addition salts of the claimed compounds to be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods. Alternatively, alkali and alkaline earth metal salts of acidic compounds of the present invention are prepared by reacting the compounds of the present invention with the appropriate base via a variety of known methods. 
     The present invention includes all possible salts of the compounds of the present invention as single salts, or as any mixture of said salts, in any ratio. 
     In the present text, in particular in the “Experimental Section”, for the synthesis of intermediates and of examples of the present invention, when a compound is mentioned as a salt form with the corresponding base or acid, the exact stoichiometric composition of said salt form, as obtained by the respective preparation and/or purification process, is, in most cases, unknown. 
     Unless specified otherwise, suffixes to chemical names or structural formulae relating to salts, such as “hydrochloride”, “trifluoroacetate”, “sodium salt”, or “×HCl”, “×CF 3 COOH”, “×Na”, for example, mean a salt form, the stoichiometry of which salt form not being specified. 
     This applies analogously to cases in which synthesis intermediates or example compounds or salts thereof have been obtained, by the preparation and/or purification processes described, as solvates, such as hydrates, with (if defined) unknown stoichiometric composition. 
     Furthermore, the present invention includes all possible crystalline forms, or polymorphs, of the compounds of the present invention, either as single polymorph, or as a mixture of more than one polymorph, in any ratio. 
     Moreover, the present invention also includes prodrugs of the compounds according to the invention. The term “prodrugs” here designates compounds which themselves can be biologically active or inactive, but are converted (for example metabolically or hydrolytically) into compounds according to the invention during their residence time in the body. 
     The invention further includes all possible cyclodextrin clathrates, i.e. alpha-, beta-, or gamma-cyclodextrins, hydroxypropyl-beta-cyclodextrins, methylbetacyclodextrins.

     The present invention covers any sub-combination within any embodiment or aspect of the present invention of compounds of general formula (I), supra. 
     The present invention covers the compounds of general formula (I) which are disclosed in the Example Section of this text, infra. 
     The compounds of general formula (I) of the present invention can be converted to any salt, preferably pharmaceutically acceptable salts, as described herein, by any method which is known to the person skilled in the art. Similarly, any salt of a compound of general formula (I) of the present invention can be converted into the free compound, by any method which is known to the person skilled in the art. 
     Compounds of general formula (I) of the present invention demonstrate a valuable pharmacological spectrum of action, which could not have been predicted. Compounds of the present invention have surprisingly been found to effectively inhibit DGKζ and it is possible therefore that said compounds be used for the treatment or prophylaxis of diseases, preferably conditions with dysregulated immune responses, particularly cancer or other disorders associated with aberrant DGKζ signaling, in mammals, including humans. 
     Disorders and conditions particularly suitable for treatment with an DGKζ inhibitor of the present invention are liquid and solid tumours, such as cancers of the breast, respiratory tract, brain, reproductive organs, digestive tract, urinary tract, eye, liver, skin, head and neck, thyroid, parathyroid and their distant metastases.

     Leukemias include, but are not limited to, acute myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia, chronic myelogenous leukemia, and hairy cell leukemia. 
     The term “treating” or “treatment” as stated throughout this document is used conventionally, for example the management or care of a subject for the purpose of combating, alleviating, reducing, relieving, improving the condition of a disease or disorder, such as a carcinoma. 
     The compounds of the present invention can be used in particular in therapy and prevention, i.e. prophylaxis, of tumour growth and metastases, especially in solid tumours of all indications and stages with or without pre-treatment of the tumour growth. 
     Generally, the use of chemotherapeutic agents and/or anti-cancer agents in combination with a compound or pharmaceutical composition of the present invention will serve to:
         1. yield better efficacy in reducing the growth of a tumour or even eliminate the tumour as compared to administration of either agent alone,   2. provide for the administration of lesser amounts of the administered chemotherapeutic agents,   3. provide for a chemotherapeutic treatment that is well tolerated in the patient with fewer deleterious pharmacological complications than observed with single agent chemotherapies and certain other combined therapies,   4. provide for treating a broader spectrum of different cancer types in mammals, especially humans,   5. provide for a higher response rate among treated patients,   6. provide for a longer survival time among treated patients compared to standard chemotherapy treatments,   7. provide a longer time for tumour progression, and/or   8. yield efficacy and tolerability results at least as good as those of the agents used alone, compared to known instances where other cancer agent combinations produce antagonistic effects.       

     In addition, the compounds of general formula (I) of the present invention can also be used in combination with radiotherapy and/or surgical intervention. 
     In a further embodiment of the present invention, the compounds of general formula (I) of the present invention are used in combination with radiation: i.e. radiation treatment sensitizes cancers to anti-tumor immune responses by induction of tumor cell death and subsequent presentation of tumor neoantigens to tumor-reactive Tcells. As DGKζ is enhancing the antigen specific activation of T cells, the overall effect results in a much stronger cancer cell attack as compared to irradiation treatment alone. 
     Thus, the present invention also provides a method of killing a tumor, wherein conventional radiation therapy is employed previous to administering one or more of the compounds of the present invention. 
     The compounds of the present invention can be administered as the sole pharmaceutical agent or in combination with one or more other pharmaceutically active ingredients where the combination causes no unacceptable adverse effects. The present invention also covers such pharmaceutical combinations. For example, the compounds of the present invention can be combined with:

     The compounds of the invention can further be combined with other reagents targeting the immune system, such as immune checkpoint inhibitors, e.g. aPD-1/-L1 axis antagonists. PD-1, along with its ligands PD-L1 and PD-L2, function as negative regulators of T cell activation. PD-L1 is overexpressed in many cancers and overexpression of PD-1 often occurs concomitantly in tumor infiltrating T cells. This results in attenuation of T cell activation and evasion of immune surveillance, which contributes to impaired antitumor immune responses. (M. E. Keir et al., Annu. Rev. Immunol. 2008, 26, 677-704). 
     In accordance with a further aspect, the present invention covers combinations comprising one or more of the compounds of general formula (I), as described herein, or stereoisomers, tautomers, N-oxides, hydrates, solvates, and salts thereof, particularly pharmaceutically acceptable salts thereof, or mixtures of same, and one or more immune checkpoint inhibitors. Preferably, the immune checkpoint inhibitor is a aPD-1/-L1 axis antagonist. 
     The compounds of the invention can further be combined with inhibitors of DGKα, such as those inhibitors of DGKα disclosed in WO2020/006016, WO2020/006018 and WO 2021/041588. As DGKα in T cells operates in a similar fashion as DGKζ, a dual inhibition profoundly enhances T cell effector functions compared with cells with deletion of either DGKζ isoform alone or wild-type cells. (M. J. Riese et al. Cancer Res. (2013), 73 (12); p. 3566-77). 
     The compounds of the invention can further be combined with chimeric antigen receptor T cells (CAR-T cells), such as Axicabtagen-Ciloleucel or Tisagenlecleucel. The activity of CAR-T cells can be suppressed by the tumor micro environment (TME). Knock out of DGKs by techniques such as Crispr had been shown to enhance CAR-T cell activity in a suppressive TME (I. Y. Jung et al., Mol. Cells 2018, 41 (8), 717-723). 
     In accordance with a further aspect, the present invention covers combinations comprising one or more compounds of general formula (I), as described herein, or stereoisomers, tautomers, N-oxides, hydrates, solvates, and salts thereof, particularly pharmaceutically acceptable salts thereof, or mixtures of same, with chimeric antigen receptor T cells, (CAR-T cells), CAR-NKT cells or CAR-NK cells. 
     Preferably, the chimeric antigen receptor T cells (CAR-T cells) are Axicabtagen-Ciloleucel or Tisagenlecleucel. 
     The present invention further provides the use of the compounds according to the invention for expansion of T cells including CAR-T and tumor infiltrated lymphocytes ex-vivo. 
     In accordance with a further aspect, the present invention covers compounds of general formula (I), as described herein, or stereoisomers, tautomers, N-oxides, hydrates, solvates, and salts thereof, particularly pharmaceutically acceptable salts thereof, or mixtures of same, for use in the expansion of T cells including CAR-T cells, CAR-NKT cells or CAR-NK cells and tumor infiltrated lymphocytes ex-vivo. 
     Hence, the present invention also relates to the use of the compounds according to the invention for the expansion of T cells, including CAR-T cell, CAR-NKT cells or CAR-NK cells and tumor infiltrated lymphocytes, ex-vivo. 
     The present invention also comprises an ex-vivo method for the expansion of T cells, including CAR-T cells, CAR-NKT cells or CAR-NK cells and tumor infiltrated lymphocytes, contacting said T cells with compounds according to the invention. 
     Compounds of the present invention can be utilized to inhibit, block, reduce or decrease DGKζ activity resulting in the modulation of dysregulated immune responses e.g. to block immunosuppression and increase immune cell activation and infiltration in the context of cancer and cancer immunotherapy that will eventually lead to reduction of tumour growth. 
     This method comprises administering to a mammal in need thereof, including a human, an amount of a compound of this invention, or a pharmaceutically acceptable salt, isomer, polymorph, metabolite, hydrate, solvate or ester thereof; which is effective to treat the disorder. The present invention also provides methods of treating a variety of other disorders wherein DGKζ is involved such as, but not limited to, disorders with dysregulated immune responses, inflammation, vaccination for infection &amp; cancer, virus infections, lymphoproliferative disorders, asthma, eye diseases, and type 2 diabetes/insulin resistance. 
     These disorders have been well characterized in humans, but also exist with a similar etiology in other mammals, and can be treated by administering pharmaceutical compositions of the present invention. 
     In accordance with a further aspect, the present invention covers compounds of general formula (I), as described supra, or stereoisomers, tautomers, N-oxides, hydrates, solvates, and salts thereof, particularly pharmaceutically acceptable salts thereof, or mixtures of same, for use in the treatment or prophylaxis of diseases, in particular cancer or conditions with dysregulated immune responses or other disorders associated with aberrant DGKζ signaling. 
     The pharmaceutical activity of the compounds according to the invention can be explained by their activity as DGKζ inhibitors. 
     In accordance with a further aspect, the present invention covers the use of compounds of general formula (I), as described supra, or stereoisomers, tautomers, N-oxides, hydrates, solvates, and salts thereof, particularly pharmaceutically acceptable salts thereof, or mixtures of same, for the treatment or prophylaxis of diseases, in particular cancer or conditions with dysregulated immune responses or other disorders associated with aberrant DGKζ signaling, particularly liquid and solid tumours.

     The present invention furthermore relates to a pharmaceutical composition which comprise at least one compound according to the invention, conventionally together with one or more pharmaceutically suitable excipient(s), and to their use according to the present invention. 
     In accordance with another aspect, the present invention covers pharmaceutical combinations, in particular medicaments, comprising at least one compound of general formula (I) of the present invention and at least one or more further active ingredients, in particular for the treatment and/or prophylaxis of cancer or conditions with dysregulated immune responses or other disorders associated with aberrant DGKζ signaling, particularly liquid and solid tumours. 
     Particularly, the present invention covers a pharmaceutical combination, which comprises:
         one or more first active ingredients, in particular compounds of general formula (I) as defined supra, and   one or more further active ingredients, in particular in particular immune checkpoint inhibitors.       

     The term “combination” in the present invention is used as known to persons skilled in the art, it being possible for said combination to be a fixed combination, a non-fixed combination or a kit-of-parts. 
     A “fixed combination” in the present invention is used as known to persons skilled in the art and is defined as a combination wherein, for example, a first active ingredient, such as one or more compounds of general formula (I) of the present invention, and a further active ingredient are present together in one unit dosage or in one single entity. One example of a “fixed combination” is a pharmaceutical composition wherein a first active ingredient and a further active ingredient are present in admixture for simultaneous administration, such as in a formulation. Another example of a “fixed combination” is a pharmaceutical combination wherein a first active ingredient and a further active ingredient are present in one unit without being in admixture. 
     A non-fixed combination or “kit-of-parts” in the present invention is used as known to persons skilled in the art and is defined as a combination wherein a first active ingredient and a further active ingredient are present in more than one unit. One example of a non-fixed combination or kit-of-parts is a combination wherein the first active ingredient and the further active ingredient are present separately. It is possible for the components of the non-fixed combination or kit-of-parts to be administered separately, sequentially, simultaneously, concurrently or chronologically staggered. 
     Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of cancer or conditions with dysregulated immune responses or other disorders associated with aberrant DGKζ signaling, by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known active ingredients or medicaments that are used to treat these conditions, the effective dosage of the compounds of the present invention can readily be determined for treatment of each desired indication. The amount of the active ingredient to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular compound and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated. 
     The total amount of the active ingredient to be administered will generally range from about 0001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 20 mg/kg body weight per day. Clinically useful dosing schedules will range from one to three times a day dosing to once every four weeks dosing. In addition, it is possible for “drug holidays”, in which a patient is not dosed with a drug for a certain period of time, to be beneficial to the overall balance between pharmacological effect and tolerability. It is possible for a unit dosage to contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The average daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight. 
     Of course the specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compound employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of treatment and number of doses of a compound of the present invention or a pharmaceutically acceptable salt or ester or composition thereof can be ascertained by those skilled in the art using conventional treatment tests. 
     General Syntheses of Compounds of the Present Invention 
     The compounds according to the invention of general formula (I) can be prepared according to the following Schemes 1, 2, 3 and 4. The schemes and procedures described below illustrate synthetic routes to the compounds of general formula (I) of the invention and are not intended to be limiting. It is clear to the person skilled in the art that the order of transformations as exemplified in Schemes 1, 2, 3 and 4 can be modified in various ways. The order of transformations exemplified in these schemes is therefore not intended to be limiting. In addition, modification of any of the substituents, R 1 , R 2 , R 3  or R 4  can be achieved before and/or after the exemplified transformations. These modifications can be such as the introduction of protecting groups, cleavage of protecting groups, reduction or oxidation of functional groups, halogenation, metallation, substitution, or coupling reactions such as amide couplings (couplings of carboxylic acids with amines) or transition metal catalysed coupling reactions (such as the well-known Suzuki coupling) known to the person skilled in the art. These transformations include those which introduce a functionality which allows for further modification of substituents. Appropriate protecting groups and their introduction and cleavage are well-known to the person skilled in the art (see for example T. W. Greene and P. G. M. Wuts in  Protective Groups in Organic Synthesis,  3 rd  edition, Wiley 1999). Specific examples are described in the subsequent paragraphs. 
     Suitable routes for the preparation of compounds of formulae (I-a) and (I-b), which are sub-sets of general formula (I), which when taken together they form, and for the preparation of compounds of formula (I-c) which, in turn constitutes a sub-set of formula (I-a), are described in Schemes 1, 2, 3 and 4.

     The reaction between intermediates of the formula (V-a) and compounds of formula (VI) proceeds selectively at the nitrogen atom attached to C-2 of the thiazole, not involving the —NH 2  group attached to C 1-4 . As shown in Scheme 2, this also applies to the analogous reaction with di-tert-butyl dicarbonate which gives compounds of formula (V-c) but not compounds of formula (V-b), said compounds of formula (V-c) being converted, upon reaction with compounds of formula (VI), in which R 2  has the meaning as given for general formula (I), and in which LG 2  represents a leaving group as defined herein, preferably a chlorine, bromine, or iodine atom, more preferably a bromine atom, in a dipolar aprotic solvent as defined herein, preferably N,N-dimethylformamide, at a temperature in the range from 60° C. to 120° C., preferably 80° C. to 100° C., more preferably 90° C., for a time in the range from 30 minutes to 24 hours, preferably from 1 hour to 4 hours, more preferably 2 hours, into compounds of the present invention, of formula (I-a), likewise.

     Compounds of formulae (II), (III), (IV), (VI), and (VII) are largely commercially available or can be prepared using methods known to the person skilled in the art, see e.g. F. Calderon et al. Journal of Medicinal Chemistry 2017, 60 (16), 6880-6896, for the preparation of isothiocyanates of formula (II); see also the synthesis protocols of Intermediates 200-208 in the Experimental Section, or Y.

     Alternatively, compounds of formula (I-a), which constitutes a sub-set of general formula (I) in which R 3  represents an amino group, can be prepared from precursors in which the R 4  group substituted with a group not covered within the definition of R 4  (such as a carboxy group), which however allows for establishing R 4  groups featuring diverse substituents from a common precursor, such as carboxamides of formula (I-c) (Scheme 4). 
     
       
         
         
             
             
         
       
     
     Scheme 4 exemplifies (without any limitation to the invention) the conversions of advanced intermediates of formula (VIII), which can be prepared using the methods described in the preceding Schemes, in combination with well-established methods such as the saponification of carboxylic esters, Thus, carboxylic acid derivatives of formula (VIII) can be reacted in well-known amide coupling reactions with amines (R 12 )(R 13 )NH, in the presence of a coupling reagent such as HATU and a tertiary amine such as triethylamine or N,N-diisopropylethylamine, and optionally in the presence of DMAP, in a dipolar aprotic solvent as defined herein, preferably N,N-dimethylformamide, at a temperature in the range from 0° C. to 50° C., preferably at room temperature as defined herein, for a time in the range from 2 hours to 24 hours, preferably from 12 hour to 20 hours, to give carboxamide compounds of the invention, of formula (I-c).

     Compound Purification—General 
     The example compounds and intermediates produced according to the methods of the invention may require purification. Purification of organic compounds is well known to the person skilled in the art and there may be several ways of purifying the same compound. In some cases, no purification may be necessary. In some cases, the compounds may be purified by crystallization. 
     In some cases, impurities may be stirred out using a suitable solvent. In some cases, the compounds may be purified by chromatography, particularly flash column chromatography, using for example prepacked silica gel cartridges, e.g. Biotage SNAP cartidges KP-Sil® or KP-NH® in combination with a Biotage autopurifier system (SP4® or Isolera Four®) and eluents such as gradients of hexane/ethyl acetate or dichloromethane/methanol. In some cases, the compounds may be purified by preparative HPLC using for example a Waters autopurifier system equipped with a diode array detector and/or on-line electrospray ionization mass spectrometer in combination with a suitable prepacked reverse phase column and eluents such as gradients of water and acetonitrile which may contain additives such as trifluoroacetic acid, formic acid or aqueous ammonia. 
     In some cases, purification methods as described above can provide those compounds of the present invention which possess a sufficiently basic or acidic functionality in the form of a salt, such as, in the case of a compound of the present invention which is sufficiently basic, a trifluoroacetate or formate salt for example, or, in the case of a compound of the present invention which is sufficiently acidic, an ammonium salt for example. A salt of this type can either be transformed into its free base or free acid form, respectively, by various methods known to the person skilled in the art, or be used as salts in subsequent biological assays. It is to be understood that the specific form (e.g. salt, free base etc.) of a compound of the present invention as isolated and as described herein is not necessarily the only form in which said compound can be applied to a biological assay in order to quantify the specific biological activity.

     Rac-2-(N-[4-amino-5-(4-benzyloxybenzoyl)thiazol-2-yl]-4-fluoro-anilino)propanamide (100 mg, 204 μmol, Example 158) was dissolved in ethanol (2.5 mL). Under nitrogen atmosphere was added palladium on carbon (325 mg, 10% purity, 306 μmol; CAS-RN 7440-05-3) and then the nitrogen atmosphere was evacuated and was replaced with hydrogen. The mixture was stirred for 3.5 h at rt under hydrogen atmosphere. Further palladium on carbon (100 μmol) was added and the mixture was stirred for a further 3 h at rt under hydrogen atmosphere. The reaction mixture was filtered over celite, washed with ethanol and the filtrate was concentrated under reduced pressure. The residue was purified by RP-HPLC (method B, basic) to give 27 mg (31% yield) of the title compound.

     EXPERIMENTAL SECTION—DETERMINATION OF ABSOLUTE STEREOCHEMISTRY BY MEANS OF X-RAY-ANALYSIS 
     Determination of the Absolute Configuration of Example 49.2 
     (R)-2-(N-[4-amino-5-[4-(difluoromethoxy)benzoyl]thiazol-2-yl]-3,4-difluoro-anilino)propanamide 
     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.

     Determination of the Absolute Configuration of Example 59.1 
     (R)-2-(N-[4-amino-5-(4-methoxybenzoyl)thiazol-2-yl]-4-chloro-3-fluoro-anilino)propanamide 
     The crystallographic data of Example 59.1 as well as a figure depicting the thermal ellipsoids and numbering of the structure, are shown in Table 14 and  FIG.  7   . Colorless crystals of Example 59.1 were obtained by slow evaporation from a toluene 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 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.

     Determination of the Absolute Configuration of Example 62.2 
     (R)-2-(N-[4-amino-5-(4-methoxybenzoyl)thiazol-2-yl]-4-fluoro-anilino)propanamide 
     The crystallographic data of Example 62.2 as well as a figure depicting the thermal ellipsoids and numbering of the structure, are shown in Table 16 and  FIG.  9   . Colorless crystals of Example 62.2 were already present in the purified sample. 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 62.2 are present. 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 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 0.004 (3). The program XP was used for molecular representations.

         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   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.       

     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. 
     The in vitro activity of the compounds of the present invention can be demonstrated in the following assays: 
     Human DGKζ Kinase Activity Inhibition Assay. 
     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”). 
     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. 
     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 2  (Sigma-Aldrich), 0.1% (w/v) bovine gamma globulin (BGG, Sigma-Aldrich), 1 μM CaCl 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 (=&gt;final conc. in the 5 μL assay volume is 7 μM), 8.33 mM octyl-β-D-glucopyranoside (=&gt;final conc. in 5 μL assay volume is 5 mM), and 91.67 μM adenosine triphosphate (=&gt;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. 
     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 50  values were calculated using Genedata Screener™ software.

     Transactivation Assay in Jurkat IL2-Reporter Cell Line 
     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. 
     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. 
     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 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). 
     Polyclonal Activation of Human PBMCs 
     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 2  from leucapherese samples was thawed and resuspended in culture medium (X-Vivo-20). 4×10 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 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. 
     In Vitro Activation of Mouse OT-I Antigen-Specific T-Cells 
     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 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. 
     DGKζ Surface Plasmon Resonance Interaction Assay 
     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 D  [M]), as well as association and dissociation rate constants (k on  [1/Ms] and k off  [1/s], respectively). The measurements were performed using Biacore® T200, Biacore® S200 or Biacore® 8K (GE Healthcare). 
     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 2  (Sigma, #M1028-100 ML), dimethyl sulfoxide (DMSO from Biomol, #54686.500). 
     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 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 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. 
     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 
     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). 
     Expression of DGKζ in Insect Cells Using the Baculovirus System 
     Expression Constructs: 
     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. 
     The DNA sequence encoded the following sequence: 
     Construct DGKζ_Hu Amino Acid M1 to V928 
     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. 
     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. 
     Generation of Recombinant Baculovirus 
     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. 
     DGKζ Expression in Sf9 Cells Using Bioreactor 
     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 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. 
     Purification of the DGKz_Hu_1 Protein: 
     Purification of the DGKz_hu_1 protein was achieved by a two-step chromatography procedure as follows. 
     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). 
     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. 
     The in vivo activity of the compounds of the present invention can be demonstrated in the following assays: 
     In Vivo Activation of Murine Antigen Specific OT-I T Cells 
     Oral Administration of compounds enhances antigen-specific T cell activation in vivo. 
     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. 
     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. 
     In Vivo Syngeneic Tumor Models 
     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 2 . 
     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
 
     Significance of monotherapies and combination treatment was calculated versus control group as determined by 2-Way ANOVA analysis.
