Description

SUBSTITUTED BICYCLIC DERIVATIVES OF PIPERIDINE USEFUL AS T CELL ACTIVATORS Field of Invention The present invention generally relates to substituted bicyclic compounds that activate T cells, promote T cell proliferation and / or exhibit antitumor activity. Substituted bicyclic compounds, compositions comprising those compounds, and methods for their use are provided herein. The invention further relates to pharmaceutical compositions comprising at least one compound according to the invention that are useful for the treatment of proliferative disorders, such as cancer and viral infections. Background of the Invention Human cancers harbor numerous genetic and epigenetic alterations, generating neoantigens potentially recognizable by the immune system (Sjoblom et al., (2006) Science 314:268-74). The adaptive immune system, composed of T and B lymphocytes, has powerful anticancer potential, with a broad capacity and exquisite specificity to respond to various tumor antigens. Furthermore, the immune system demonstrates considerable plasticity and a memory component. The successful use of all these attributes Ref. 334520 of the adaptive immune system would make immunotherapy unique among all cancer treatment modalities. However, although an endogenous immune response to cancer is observed in preclinical models and patients, this response is ineffective, and established cancers are considered self-reported and tolerated by the immune system. By contributing to this state of tolerance, tumors can exploit several distinct mechanisms to actively subvert antitumor immunity. These mechanisms include dysfunctional T cell signaling (Mizoguchi et al., (1992) Science 258: 1795-98), suppressive regulatory cells (Facciabene et al., (2012) Cancer Res. 72: 2162-71), and co-option of endogenous immune checkpoints, which serve to decrease the intensity of adaptive immune responses and protect normal tissues from collateral damage, by tumors to evade immune destruction (Topalian et al., (2012) Curr. Opin Immunol. 24:1-6; Mellman, (2011) Nature 480:480-489). Diacylglycerol kinases (DGKs) are lipid kinases that mediate the conversion of diacylglycerol to phosphatidic acid, thereby terminating T cell functions propagated through the TCR signaling pathway. Therefore, DGKs serve as intracellular checkpoints and inhibition of DGKs is expected to enhance T cell signaling pathways and T cell activation. Supporting evidence includes gene knockout mouse models either DGKa or DGK / showing a hyper-reactive T cell phenotype and enhanced antitumor immune activity (Riese M. J. et al., Journal of Biological Chemlstry, (2011) 7: 5254-5265; Zha Y et al., Nature Immunology, (2006) 12: 1343; Olenchock B. A., et al., (2006) 11: 1174-81). Furthermore, tumor-infiltrating lymphocytes isolated from patients with human renal cell carcinoma were observed to overexpress DGKa resulting in inhibited T cell function (Prinz, PU et al., J Immunology (2012) 12: 5990- 6000). Therefore, DGKa and DGK / are considered as targets for cancer immunotherapy (Riese M.J., Front Cell Dev Blol. (2016) 4: 108; Chen, S.S., Front Cell Dev Biol. (2016) 4: 130; Avila-Flores, A., Immunology and Cell Biology (2017) 95: 549-563; Noessner, E., Front Cell Dev Biol. (2017) 5: 16; Krishna, S., et al. Front Immunology (2013) 4:178; Jing, W. et al., Cancer Research (2017) 77: 5676-5686. There remains a need for compounds useful as inhibitors of one or both DGKa and DGK / . Additionally, there remains a need for compounds useful as inhibitors of one or both DGKa and DGK / that have selectivity over other diacylglycerol kinases, protein kinases and / or other lipid kinases. Accordingly, an agent that is safe and effective in restoring T cell activation, lowering the antigen threshold, enhancing antitumor functionality, and / or overcoming the suppressive effects of one or more endogenous immune checkpoints, such as PD-1 , LAG-3 and TGFP, would be an important addition to the treatment of patients with proliferative disorders, such as cancer and viral infections.

The term pharmaceutical composition means a composition comprising a compound of the invention in combination with at least one additional pharmaceutically acceptable carrier. Pharmaceutically acceptable carriers are formulated according to a number of factors that are within the 117 scope of those skilled in the art. These include, without limitation: the type and nature of the active agent being formulated; the subject to whom the composition containing the agent is to be administered; the intended route of administration of the composition; and the therapeutic indication to which it is directed. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semisolid dosage forms. Such carriers may include several different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those skilled in the art. . Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Alien, LV Jr. et al., Remlngton: The Science and Practice of Pharmacy (2 Volumes) , 22nd Edition (2012), Pharmaceutical Press. The dosage regimen for the compounds of the present invention will, of course, vary depending on known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, condition 118 medical, and weight of the recipient; the nature and extent of the symptoms; the type of concurrent treatment; the frequency of treatment; the route of administration, the patient's kidney and liver function, and the desired effect. As a general guide, the daily oral dosage of each active ingredient, when used for the indicated effects, will range from about 0.001 to about 5000 mg per day, preferably from about 0.01 to about 1000 mg per day, and more preferably from about 0.1 to 250 mg per day. mg approximately per day. Intravenously, the most preferred doses will range from approximately 0.01 to 10 mg / kg / minute during a constant rate infusion. The compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses two, three, or four times a day. The compounds are typically administered in admixture with suitable diluents, excipients or pharmaceutical vehicles (collectively known herein as pharmaceutical vehicles) suitably selected with respect to the intended form of administration, e.g., oral tablets, capsules, elixirs and syrups, and consistent with conventional pharmaceutical practices. Suitable dosage forms (pharmaceutical compositions) for administration may contain 1 119 milligram to approximately 2000 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions, the active ingredient will typically be present in an amount of about 0.1-95% by weight based on the total weight of the composition. A typical capsule for oral administration contains at least one of the compounds of the present invention (250 mg), lactose (75 mg) and magnesium stearate (15 mg). The mixture is passed through a 60 mesh sieve and packed into a No. L gelatin capsule. A typical injectable preparation is produced by aseptically placing at least one of the compounds of the present invention (250 mg) in a vial, lyophilizing and aseptically sealing. For use, the contents of the vial are mixed with 2 mL of physiological saline solution, to produce an injectable preparation. The present invention includes within its scope pharmaceutical compositions comprising, as an active ingredient, a therapeutically effective amount of at least one of the compounds of the present invention, alone or in combination with a pharmaceutical carrier. Optionally, the compounds of the present invention may be used alone, in combination with other compounds of the invention, or in combination with one or more other therapeutic agents, e.g. , an anti-cancer agent or other material 120 pharmaceutically active. Regardless of the route of administration selected, the compounds of the present invention, which can be used in a suitable hydrated form, and / or the pharmaceutical compositions of the present invention, are formulated into pharmaceutically acceptable dosage forms by conventional methods known to those of experts in the technique. The actual dosage levels of the active ingredients in the pharmaceutical compositions of the present invention can be varied to obtain an amount of the active ingredient that is effective in achieving the therapeutic response for a particular patient, composition, and mode of administration, without being toxic. for the patient. The dosage level selected will depend on a variety of factors including the activity of the particular compound employed of the present invention, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of excretion or metabolism of the particular compound used, the rate and extent of absorption, duration of treatment, other drugs, compounds and / or materials used in combination with the particular compound used, age, sex, weight, condition, general health and history previous medical 121 patient treated, and factors of this type known in medical techniques. A physician or veterinarian having ordinary skill in the art can easily determine and prescribe the effective amount of the pharmaceutical composition required. For example, the physician or veterinarian may start with doses of the antibodies of the invention used in the pharmaceutical composition at levels lower than those required to achieve the therapeutic effect and gradually increase the dosage until the effect is achieved. In general, an adequate daily dose of a compound of the invention will be that amount of the compound that is the lowest effective dose to produce a therapeutic effect. Such effective dosage will generally depend on the factors described above. In general, oral, intravenous, intracerebroventricular and subcutaneous doses of the compounds of this invention for a patient will range from approximately 0.01 to 50 mg per kilogram of body weight per day. If desired, the effective daily dose of the active compound may be administered as two, three, four, five, six or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms. In certain aspects of the invention, 122 the dosage is one administration per day. While it is possible for a compound of the present invention to be administered alone, it is preferable to administer the compound as a pharmaceutical formulation (composition). The above other therapeutic agents, when used in combination with the compounds of the present invention, can be used, for example, in the amounts indicated in the Physicians' Desk Reference (PDR) or as determined by one skilled in the art. In the methods of the present invention, such other therapeutic agents may be administered before, simultaneously with, or after administration of the compounds of the invention. PREPARATION METHODS The compounds of the present invention can be synthesized by many methods available to those skilled in the art of organic chemistry. General synthetic reaction schemes for preparing compounds of the present invention are described below. These reaction schemes are illustrative and are not intended to limit the possible techniques that one skilled in the art can use to prepare the compounds described herein. Different methods for preparing the compounds of the present invention will be apparent to those skilled in the art. Examples of compounds of the present invention 123 prepared by methods described in the general reaction schemes are given in the Examples section below. The preparation of homochiral examples can be carried out by techniques known to those skilled in the art. For example, homochiral compounds can be prepared by separation of racemic or diastereomeric products by chiral phase preparative HPLC. Alternatively, the example compounds can be prepared by known methods to give enantiomerically or diastereomerically enriched products. The reactions and techniques described in this section are carried out in appropriate solvents for the reagents and materials used and are suitable for the transformations carried out. Furthermore, in the description of the synthetic methods given below, it should be understood that all proposed reaction conditions, including the choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment, and workup procedures, are chosen as standard conditions for that reaction, which should be easily recognized by one skilled in the art. An expert in the art of organic synthesis understands that the functionality present in various portions of the molecule must be compatible with the proposed reagents and reactions. Such restrictions on substituents that are 124 compatible with the reaction conditions will be readily apparent to one skilled in the art, with alternatives required when incompatible substituents are present. This will sometimes require judgment to modify the order of synthetic steps or to select one particular process reaction scheme over another in order to obtain a compound of the invention. It will also be recognized that another important consideration in planning any synthetic route in this field is the judicious choice of a protecting group used for the protection of reactive functional groups present in the compounds described in this invention. An authoritative account that describes the many alternatives to the trained professional is Wuts and Greene, Greene's Protective Groups in Organic Synthesis, Fourth Edition, Wiley and Sons (2007). In a further enablement, intermediates and examples of the present invention can be prepared using stereoselective methodologies known in the art, examples of which are shown in the following reaction schemes. 125 REACTION SCHEME I Both antipodes of chiral oxazolidinones of the type represented can be reacted with acyl chlorides at low temperature to produce N-acyl derivatives. These can be converted to the related boron enolates and condensed with 2-(2-alkyl-l,3-dioxolan-2-yl)acetaldehydes to produce 4-benzyl-3-(2-alkyl-3-hydroxy-4-( 2-alkyl-l,3dioxolan-2-yl)butanoyl)oxazolidinones of known stereochemistry. Deprotection of the dioxolane product using, for example, ferric chloride in acetone can produce l—(4—benzyl-2-oxooxazolidin-3-yl)-2-alkyl-3-hydroxyalkyl-l,5diones. The subsequent reductive amination using benzylamine 126 with, for example, sodium triacetoxyborohydride can provide diastereomeric mixtures of 4-benzyl-3-(5(benzylamino)-2-alkyl-3-hydroxyalkanoyl)oxazolidinones. The resulting amines can be cyclized intramolecularly by heating in MeOH under microwave conditions to provide chromatographically separable l-benzyl-3-alkyl-4-hydroxy-6-alkylpiperidin-2ones. Successive reduction of the product piperidinones with, for example, borane or LAH can produce N-benzyl-2-alkyl-4-hydroxy-5alkylpiperidines. Removal of the benzyl moiety under hydrogenolysis conditions in the presence of di-tert-butyl dicarbonate can allow access to tere-butyl 4-hydroxy-2,5dialkylpiperidine-l-carboxylates which are useful intermediates in the synthesis of examples. of the present invention. In a further step, the stereochemistry of the 4-hydroxy moiety in these and other related intermediates can be reversed using standard Mitsunobu conditions employing p-nitrobenzoic acid to produce esters from which the desired alcohols can be released by base-catalyzed hydrolysis. The use of these methodologies with properly functionalized oxazolidinones and aldehydes can produce intermediates of known stereochemistry. An example of the use of these compounds to access additional modalities of the present invention is shown in the methodologies described 127 in the following reaction scheme. REACTION SCHEME II fice Bcc A CU nr *J Ar = aryl or heteroaryl X = CI or Triflate In these cases, N-boc-protected 2,5-dialkyl-4-hydroxypiperidines can be first deprotected under standard conditions and then reacted with 1alkylpyrido[3,2-d]pyrimidin-2(1H)-ones or l-alkyl- 1,5naphthyridin-2(1H)-ones to give product alcohols which can subsequently be reacted under Mitsunobu conditions, or with selected heterocycles under SNAr conditions to give examples of the present invention. 128 Alternatively, N-boc protected 2,5-dialkyl-4-hydroxypiperidines can be reacted first under Mitsunobu conditions with appropriately functionalized phenols, or with selected heterocycles under SNAr conditions to give additional intermediates of the type represented above. Subsequent reaction with suitable functionalized pyrido[3,2-d]pyrimidin-2(1H)-ones or pyridin-2(1H)-ones may provide access to additional examples. In some cases, 2,5-dialkyl-4hydroxypiperidines or their related ethers can be reacted with 4,6-dichloro-l-alkylpyrido[3,2-d]pyrimidin2(lH)-ones or 4,6-dichloro- l-alkyl-l,5-naphthyridin-2(1H)-ones to access the related 4-N-piperidinyl derivatives, thus facilitating the introduction of additional functionality in the 6-position of the bicyclic heterocyl, for example a nitrile group, which are additional embodiments of the present invention.

Common intermediaries are generally useful for the preparation of more than one Example and are identified sequentially (e.g., Intermediary 1, Intermediary 2, etc.) and abbreviated as Int. 1 or II, Int. 2 or 12, etc. Compounds in the Examples are identified by the example and step in which they were prepared (e.g., 1-A denotes Example 1, step A), or by the example alone where the compound is the title compound of the example (e.g. , 1 denotes the title compound of Example 1). In some cases, alternative preparations of intermediate products or examples are described. Often, chemists skilled in the art of synthesis can devise alternative preparations that may be desirable based on one or more considerations, such as shorter reaction time, less expensive starting materials, ease of operation or isolation, yield. improved, susceptible to catalysis, avoidance of toxic reagents, accessibility of specialized instrumentation, and decreased number of linear steps, etc. The intention of describing alternative preparations is to further enable the preparation of the examples of this invention. In some cases, some functional groups in the examples and claims outlined may be replaced by well-known bioisosteric replacements known in the art, e.g. 130 replacement of a carboxylic acid group with a tetrazole or phosphate moiety. NMR data collected in deuterated dimethyl sulfoxide used water suppression in data processing. The reported spectra are not corrected for the effects of water suppression. Protons adjacent to the water suppression frequency of 3.35 ppm show decreased signal intensity. In the examples, the use of wedge bonds and dotted lines implies relative stereochemistry. The designation (+ / -) preceding the name of a compound indicates a racemic mixture. The designation (reí) indicates that all stereochemical designations of the compound are relative and not absolute. The use of a bond without dashed lines at a chiral center implies unknown relative stereochemistry. In the following tables, the stereochemistry of the example is shown in the column labeled Stereo.

Benzoxazma-2,4 (1H)-diones of the type shown are They can be treated with a strong base and a methylation reagent such as methyl iodide to produce l-methyl-2Hbenzo[di[1,3]oxazine-2,4(1H)-diones. These can be treated, for example, with nitro-acetate to generate l-methyl-3133 nitroquinoline-2,4(1H,3H)-diones. Such compounds, in turn, can be converted to the related 4-chloro derivatives that can react with a variety of functionalized piperidines to provide examples of the present invention. In other methodologies, picolinic acids can be esterified under standard conditions and then treated with, for example, acetic anhydride to provide ethyl 3acetamidopicolinates. These can be alkylated under standard conditions and subsequently treated with a mixture of hydrogen peroxide and trifluoroacetic anhydride to access related N-oxides, for example, 2-(ethoxycarbonyl)-3-(N-methylacetamido)pyridine 1-oxide. Under conditions known in the art, these intermediates can be converted to 6-cyano-3-(N-methylacetamido)picolinates which upon base treatment can cyclize to provide 1,5-naphthyridine-2,4(1H,3H)- dionas. Compounds of this type can be derived in a plurality of ways to access various useful intermediates. For example, treatment under standard nitration conditions can generate the related l-methyl-3-nitro-l,5-naphthyridine-2,4(1H, 3H) diones that can be converted under standard conditions to 4-chloro-intermediates. or 4-trifluoromethanesulfonate that can be reacted with a variety of functionalized piperidines to provide 134 additional examples of the present invention. Alternatively, treatment under bromination conditions, for example N-bromosuccinimide in DMF, can give the related 3-bromo derivatives, which when derivatized as described above allow both the introduction of a variety of piperidines at the 4-position of the heterocycle , as well as an additional derivatization at the 3-position of naphthyridine. For example, aromatic and heteroaromatic moieties can be introduced into this vector by coupling chemistries known in the art. In a further methodology, ethyl 3-amino-6bromopicolinates generated from the related ethyl 3-aminopicolinates can be treated as described above to provide 6-bromo-l-methyl-l,5naphthyridine-2,4(1H, 3H)-diones that allow the introduction of a variety of moieties at position 6 of the naphthyridine heterocycle, an example being the introduction of the cyano function at this position as shown in Reaction Scheme 1. 135 REACTION SCHEME 1 h2o2 TFAA I JES DMF The following reaction scheme shows 136 additional methodologies that may be useful in the synthesis of intermediates of the present invention. Ethyl 3-amino-6-bromopicolinates under treatment with 2-cyanoacetyl chloride can be cyclized to generate 6-bromo-2,4-dioxo-l,2,3,4-tetrahydro-l,5naphthyridine-3- carbonitriles. These can be alkylated to NI under standard conditions and subsequently converted to the related 6-bromo-3-cyano-l-methyl-2-oxo-l,2-dihydro-l,5naphthyridin-4-yl sulfonates that are useful in preparation of other examples. Alternatively, sequential treatments with POC13 and HC1 in dioxane give access to 4,6dichloro-l-methyl-2-oxo-l,2-dihydro-l,5-naphthyridine-3carbonitriles which are also useful intermediates.

Additional useful intermediates can be prepared by condensing suitably functionalized naphthyridinone and quinolone heterocycles with variously functionalized piperidines as indicated in the following reaction scheme. Such intermediates can be exemplified by the present invention by further elaboration using, for example, Mitsunobu or SNAr reactions with appropriately functionalized aromatic or heteroaromatic coupling partners. 138 REACTION SCHEME 3 Preparation of useful piperidine intermediates and additional examples is shown in the reaction scheme below. REACTION SCHEME 4 OH Ar In these cases, N-protected cis-4-hydroxy-3alkylpiperidines can be treated with acids. 139 carboxylic acids, for example under Mitsunobu conditions, to provide trans-4-benzoyloxy-3-alkylpiperidines. These can subsequently be hydrolyzed to access the related trans4-hydroxy-3-alkylpiperidines which can be used in a methodology analogous to that discussed above, whereby subsequent deprotection and condensation of the trans 4-hydroxy-3-alkylpiperidines intermediates with naphthyridinones or appropriately functionalized quinolones generates trans-4-hydroxy-3-alkylpiperidin-l-yl)-5-methyl-6-oxo5,6-dihydro-l,5-naphthyridine or related quinolone intermediates that can react again under Mitsunobu conditions or SNAr to provide additional examples of the present invention. In other cases, it may be preferable to prepare intermediate piperidine ethers that can subsequently be reacted with appropriately functionalized naphthyridinones and quinolones to provide additional examples. Some illustrative examples are shown in the following reaction schemes. In this methodology, N-protected alkylpiperidin-4-ones of the type shown can be reduced by methods known in the art to provide access to N-protected 3-alkylpiperidin-4-ols. 140 REACTION SCHEME 5 boc h:po4 NaBH OH dicartcratc di-tert-butylc OH The relative stereochemistry of the alkyl and hydroxyl substituents can be controlled by numerous methods, some examples being concurrent treatment with phosphoric acid and sodium borohydride to give 141 predominantly the trans product, or the use of L-selectride in THF to give predominantly the cis- product as shown. Further treatment of these intermediates with a strong base and appropriately functionalized heterocycles under SNAR conditions can result in the synthesis of N-protected cis- or trans-3-alkyl-4(heteroaryloxy)piperidines. These deprotection intermediates can be reacted with suitably functionalized naphthyridinones or quinolones to provide a variety of examples of the present invention.
