Description

[Background technology]

[0001] 1. Background of the Invention 1.1 cGAS inhibitors Innate immunity is considered a frontline cellular stress response that protects host cells from invading pathogens and initiates signaling to the adaptive immune system. These processes are triggered by conserved pathogen-associated molecular patterns (PAMPs) through sensing by diverse pattern recognition receptors (PRRs) and subsequent activation of cytokine and type I interferon gene expression. Primary antigen-presenting cells, such as monocytes, macrophages, and dendritic cells, produce type I interferons and are crucial for triggering adaptive immune responses in T and B cells. Primary PRRs detect aberrant nucleic acids—i.e., mislocalized, immature, or unmodified nucleic acids—on the cell surface, within lysosomal membranes, or within other cellular compartments (Barbalat et al., Annu. Rev. Immunol. 29, 185-214 (2011)).

[0002] "Cyclic GMP-AMP synthetase ( C yclic G MP- A MP S synthesis)" ( cGAS, UniProtKB-Q8N884) is a major sensor of aberrant double-stranded DNA (dsDNA) derived from pathogens or from mislocalization or processing of cellular dsDNA in the nucleus or mitochondria (Sun et al., Science 339, 786-791 (2013); Wu et al., Science 339, 826-830 (2013); Ablasser et al., Nature 498, 380-384 (2013)). Binding of dsDNA to cGAS activates a reaction of GTP and ATP to form the cyclic dinucleotide GMP-AMP (termed cGAMP). cGAMP then binds to the endoplasmic reticulum membrane-bound adaptor protein "Stimulator of Interferon Genes (SIFN-1)." In terferon G enes)" ( STING ) and activates the protein. Activated STING binds to TANK-binding kinase ( T ANK- b inding k inase) 1 ( TBK1 ), which recruits and activates interferon regulatory factor (IFN)-1 (IFN-1), which induces the mRNA expression of cytokines and type I interferons. i Interferon r egulatory f actor)( IRF ) family of transcription factors.

[0003] The crucial role of cGAS in sensing dsDNA has been demonstrated in various pathogenic bacteria (Hansen et al., EMBOJ. 33, 1654 (2014)), viruses (Ma et al., PNAS 112, E4306 (2015)), and retroviruses (Gao et al., Science 341, 903-906 (2013)). Additionally, cGAS is essential in various other biological processes, such as cellular senescence (Yang et al., PNAS 114, E4612 (2017), Gluck et al., Nat. Cell Biol. 19, 1061-1070 (2017)) and the recognition of ruptured micronuclei in the surveillance of potential cancer cells (Mackenzie et al., Nature 548, 461-465 (2017); Harding et al., Nature 548, 466-470 (2017)). While the cGAS pathway is important for host defense against invading pathogens, cellular stress and genetic factors can also lead to the production of abnormal cellular dsDNA, for example, through nuclear or mitochondrial leakage, which can trigger an autoinflammatory response. Aicardi-Goutières syndrome (AGS; Crow et al., Nat. Genet. 38, 917-920 (2006)), a severe lupus-like autoinflammatory immune-mediated disorder, results from loss-of-function mutations in the major DNA exonuclease TREX1, which is responsible for the degradation of abnormal DNA in the cytosol. Knocking out cGAS in TREX1-deficient mice prevents otherwise lethal autoimmune responses, supporting cGAS as a driver of interferonopathy (Gray et al., J. Immunol. 195, 1939-1943 (2015); Gao et al., PNAS 112, E5699-E5705 (2015)). Similarly, embryonic lethality caused by deficiency of DNAse2, an endonuclease responsible for degrading excess DNA in lysosomes during endocytosis, was fully rescued by additional knockout of cGAS (Gao et al., PNAS 112, E5699-E5705 (2015)) or STING (Ahn et al., PNAS 109, 19386-19391 (2012)). These observations support cGAS as a drug target, and inhibition of cGAS could provide a therapeutic strategy for preventing autoinflammation and treating diseases such as systemic lupus erythematosus (SLE), which are associated with anti-dsDNA antibodies (Pisetsky et al., Nat. Rev. Rheumatol. 12, 102-110 (2016)).

[0004] 1.2 Prior art Due to the observation that inhibition of the cGAS pathway can prevent autoinflammation and provide a therapeutic strategy for treating, for example, autoimmune diseases, many attempts have been made to develop cGAS inhibitors. For example, WO 2019 / 241787 reports that methyl 4-amino-6-(phenylamino)-1,3,5-triazine-2-carboxylates such as CU-32 and CU-76 have an "in vitro hcGAS IC" of slightly below 1 μM. 50 value" (IC 50 (CU-32) = 0.66 μM and IC 50 (CU-76=0.27 μM) Hall et al., PLoS ONE 12(9); e0184843 (2017) reported that the compound PF-06928215 had an in vitro hcGAS IC of 0.049 μM as measured by a fluorescence polarization assay. 50 However, compound PF-06928215 did not exhibit acceptable cellular activity as a cGAS inhibitor.

[0005] In WO 2020 / 142729 and WO 2022 / 174012, (benzofuro[3,2-d]pyrimidin-4-yl)pyrrolidine-2-carboxylic acid derivatives were disclosed as cGAS inhibitors for treating autoimmune disorders such as Aicardi-Goutieres syndrome (AGS), lupus erythematosus, scleroderma, inflammatory bowel disease, and nonalcoholic steatohepatitis (NASH). However, the compounds of the present invention differ from the (benzofuro[3,2-d]pyrimidin-4-yl)pyrrolidine-2-carboxylic acid derivatives of WO 2020 / 142729 in that the substitution pattern at the 4-position of the pyrrolidine ring is completely different. Recently provided cGAS inhibitors, such as those in WO 2020 / 142729 or WO 2022 / 174012, typically exhibit insufficient cellular cGAS inhibitory potency (IC for inhibition of the cGAS / STING pathway). 50 However, to ensure that a compound can demonstrate therapeutic efficacy in patients, it is necessary to have a satisfactory biochemical (in vitro) inhibitory potency ("hcGAS IC 50") as well as satisfactory cytostatic potency (e.g., inhibition of IFN induction in virus-stimulated THP-1 cells (THP1 (vir) I C 50 It is critically important to provide therapeutic cGAS inhibitors that demonstrate (by demonstrating) satisfactory cGAS selectivity (versus off-target activity) and acceptable inhibitory potency in human whole blood.

[0006] Surprisingly, it has now been found that compounds of formula I, II, or III simultaneously exhibit the following three properties: Satisfactory biochemical (in vitro) IC for cGAS inhibition 50 hcGAS IC value (≦100 nM, preferably ≦50 nM, in particular ≦10 nM) 50 ), Satisfactory "inhibition of IFN induction in virus-stimulated THP-1 cells (THP1 IC of ≦1 μM, preferably ≦500 nM, more preferably ≦100 nM, especially ≦50 nM) 50(vir) ), and Satisfactory selectivity for cGAS inhibition (THP1 IC of ≥ 10, more preferably ≥ 50, more preferably ≥ 500, especially ≥ 1000) 50(cGAMP) / THP1 IC 50(vir) ratio).

[0007] Additionally, compounds of Formula I, II, or III exhibit acceptable IC values ​​for inhibition of IFN induction in a dsDNA-stimulated human whole blood assay. 50 human whole blood IC50 for cGAS inhibition of ≤ 5000 nM, more preferably ≤ 1000 nM, especially ≤ 100 nM 50 Value (hWB IC 50 ) is also shown.

[0008] The cGAS inhibitors of the present invention, particularly those with this pharmacological profile that combines excellent in vitro inhibitory potency and excellent cellular inhibitory potency with high selectivity for cGAS inhibition, are also likely to exhibit good therapeutic efficacy in patients. Due to their high cellular inhibitory potency, particularly those with this pharmacological profile, compounds should be able to cross cell membrane barriers and thus reach their intracellular target locations, and due to their selectivity to exclusively inhibit cGAS activity, these compounds should not exhibit undesirable off-target effects, such as side effects or cytotoxic effects elsewhere in the signaling pathway downstream of cGAS.

[0055] 4.Synthesis method General Procedure The following methods are suitable for preparing compounds of general formula I, II, or III. The compounds according to the invention can be obtained using synthetic methods known to those skilled in the art and described in the literature of organic synthesis. General methods for functional group protection and deprotection steps are described, for example, in Greene, TW and Wuts, PGM (eds.): Protective Groups in Organic Synthesis, third edition 1999; John Wiley and Sons, Inc. Preferably, the compounds are obtained analogously to the preparation methods described in more detail hereinafter, in particular in the experimental section. The compounds of general formula (I) can be prepared using several alternative synthetic routes, of which the following routes serve as examples:

[0056] Route A: Compounds of general formulae I, II, and III (particularly where A represents -CH2- or substituted -CH2-) can be reached from compounds of formula (AI) through standard amidation procedures. R13 can thereby represent hydrogen or a protecting group such as tert-butyl, which can be removed by standard deprotection methods. Compounds of formula (AI) can be prepared from compounds of formula (A-II) by applying standard deprotection methods. Compounds of formula (A-II) can be prepared by reacting compounds of formula (A-III) with compounds of formula (A-IV) by applying a strong base such as sodium hydride. Methods applicable to the preparation of compound (A-III) will be apparent to those skilled in the art by reference to Routes B and C described below and the examples described in the experimental section. Compounds of formula (A-IV) can be prepared through the method described hereinafter for the synthesis of intermediate B. R according to formulas (A-II) and (A-III) can represent hydrogen or a protecting group selected from the group consisting of tert-butyl, methyl, ethyl, and benzyl.

[0057] [ka]

[0058] Route B: Compounds of general formulas I, II, and III can be prepared by reacting a compound of general formula (BI) in the presence of a strong base, such as sodium hydride. R13 can represent hydrogen or a protecting group, such as tert-butyl, which can be removed by standard deprotection methods. Compound (BI) can be prepared by oxidizing a compound of general formula (B-II), for example, by applying 3-chloroperbenzoic acid. Compound (B-II) can be prepared by reacting a compound of general formula (B-III) with a compound of general formula (B-IV) by applying standard amidation conditions. Methods applicable to the preparation of compound (B-III) will be apparent to those skilled in the art by reference to the synthesis of compound (B-VI) and Route C described below, as well as the examples described in the experimental section. Compounds of formula (B-IV) can be prepared through the method described below for the synthesis of intermediate B. Alternatively, compound (B-II) can be prepared by reacting a compound of general formula (BV) with the respective enantiopure hydroxyproline, optionally in the presence of a base. Compound (BV) can be obtained through chlorination of a compound of general formula (B-VI) by applying phosphoryl chloride. Compound (B-VI) can be prepared from a compound of general formula (B-VII) by applying strong alkaline conditions, for example, at elevated temperature. Compound (B-VII) can be reached by reacting a compound of general formula (B-VIII) with a compound of general formula (B-IX) by applying a standard amidation procedure. Compounds of general formula (B-VIII) can be prepared by the methods exemplified below or other standard synthetic methods known to those skilled in the art.

[0059] [ka]

[0060] Route C: Compounds of the general formula can be prepared from compounds of the general formula (CI) by various types of ring-closing reactions, exemplified by, but not limited to, Heck-type coupling reactions (R11 represents a bromine or iodine atom and R12 contains a terminal alkene), ring-closing metathesis reactions (both R11 and R12 contain a terminal alkene), followed by hydrogenation of the resulting alkene, amidation (R11 carries a carboxylic acid and R12 carries a primary or secondary amino group, or vice versa). R13 can thereby represent hydrogen or a protecting group, such as tert-butyl, which can be removed by standard deprotection methods. Methods for the synthesis of compounds (CI) will be apparent to those skilled in the art by reference to Routes A and B above and the examples described in the experimental section.

In other cases, the absolute configuration was assigned based on the premise that the more potent diastereoisomer always has the (S,S,S,S)-configuration.

[0138] Example 1.01 (General Procedures A, B, C, D) [ka]

[0139] Step 1 (General Procedure A): To intermediate NA (216 mg; 0.418 mmol) and intermediate B-01 (188 mg; 0.439 mmol) dissolved in DMA (4.05 mL) in oven-dried glassware under an argon atmosphere was added sodium hydride (55% in mineral oil; 73.0 mg; 1.67 mmol). After the bubbling subsided, the reaction was warmed to 35 °C and stirred for an additional 25 min. The reaction was then quenched by the addition of ice-water, diluted with EtOAc, and acidified by the addition of aqueous hydrochloric acid (1 M; 1.7 mL). The mixture was extracted three times with EtOAc, and the combined organic layers were washed subsequently with water and brine and evaporated to dryness. The crude reaction mixture was purified by FC (silica gel; cyclohexane / EtOAc 25% to 100%). ESI-MS: 833 [M+H] + R t (HPLC): 0.92 min (Method B)

Because HPLC reaction control showed low conversion, additional TosOH (45.0 mg; 0.237 mmol) was added, and the mixture was further heated at 40 °C until HPLC reaction control showed high conversion to the desired product. DMF and a drop of water were added, and the mixture was then filtered and subjected to HPLC purification (Sunfire C18; ACN / water, TFA as modifier). ESI-MS: 733 [M+H] + R t (HPLC): 0.62 min (Method B)

[0141] Step 3 (General Procedure C): In oven-dried glassware under argon, a solution of HATU (81.2 mg; 0.214 mmol) in DMF (4 mL) was slowly added with a syringe pump to a solution of the intermediate from step 2 (145 mg; 0.198 mmol) in DMF (12 mL) under vigorous stirring. The mixture was further stirred until reaction control by HPLC showed high conversion to the desired product. The reaction was then quenched by the addition of water and extracted three times with EtOAc. The combined organic layers were subsequently washed with water and brine and evaporated to dryness. The crude reaction mixture was purified by FC (cyclohexane / EtOAc 50% → 100%, then EtOAc / MeOH 0% → 10%). ESI-MS: 715 [M+H] + R t (HPLC): 0.80 min (Method B)

[0142] Step 4 (General Procedure D): A mixture of the Step 3 intermediate (79.0 mg; 0.110 mmol), DCM (1.06 mL), and TFA (852 μL) was stirred at room temperature for 90 minutes. Because HPLC control of the reaction indicated low conversion, the temperature was increased to 37 °C and stirring was continued for 3 hours. Because HPLC control of the reaction still indicated low conversion, the temperature was increased to 45 °C and stirring was continued until HPLC control indicated high conversion to the desired product. The mixture was evaporated, and the crude product was purified by preparative HPLC (Sunfire C18; ACN / water, TFA as modifier). ESI-MS: 659 [M+H] + R t (HPLC): 0.83 min (Method E)

[0214] On page 45 of International Publication No. 2020 / 142729, only Compound No. 25 had a "biochemical (in vitro) IC40 of less than 100 nM." 50 It is disclosed that the compounds can be designated as "Group A" having "biochemical (in vitro) IC values" higher than 100 nM. All of the other example compounds in WO 2020 / 142729 have "biochemical (in vitro) IC values" higher than 100 nM. 50 Indicates "value". Selected prior art compounds of WO 2020 / 142729, including Compound No. 25, were synthesized and then tested for their pharmacological properties with respect to their potency in inhibiting the cGAS / STING pathway using the exact same assays used to test the compounds of the present invention. In particular, the structurally closest examples of WO 2020 / 142729 were tested for cGAS inhibition using "biochemical (in vitro) IC 50 value" (hcGAS IC 50), "Cellular IC for inhibition of IFN induction in virus-stimulated THP1 cells" 50 value" (THP1 (vir) I C 50 ), "Cell IC on the inhibition of IFN induction in cGAMP-stimulated THP1 cells" 50 value" (THP1 (cGAMP) I C 50 ), and "IC for inhibition of IFN induction in human whole blood" 50 The "hWB" (human weight basis) values ​​were experimentally determined according to the assay methods described in Section 6 below (see Table 2).

[0215] [Table 14-1] [Table 14-2]

[0216] The pharmacological properties of the example compounds of the present invention summarized in Table 1 and the respective pharmacological properties of the compounds of WO 2020 / 142729 summarized in Table 2 were experimentally determined according to the same assay procedures described in Section 6 below and can therefore be compared to each other. From the data shown in Table 2 (WO 2020 / 142729), it is clear that the “biochemical (in vitro) IC 50 value" (= hcGAS IC 50 With the sole exception of Example No. 25 of WO 2020 / 142729 (designated as "Group A" having a "biochemical (in vitro IC50"), all of the example compounds of WO 2020 / 142729 have "biochemical (in vitro IC50") significantly higher than 100 nM. 50 value" (= hcGAS IC 50 In contrast, all of the example compounds of the present invention exhibit a "biochemical (in vitro) IC" of less than 100 nM. 50 value" (hcGAS IC 50 However, it has a biochemical (in vitro) IC50 of 55 nM. 50value" (hcGAS IC 50 Example No. 25 of WO 2020 / 142729 having the formula THP1 (vir) I C 50 is 17 μM, so THP1 is lower than 1 μM (vir) I C 50 These compounds do not at all meet the selection criteria of "satisfactory cell inhibitory potency" as indicated by

[0217] 5.2.2 Compounds of WO 2022 / 174012 In WO 2022 / 174012, cGAS inhibitors with partially similar structures were disclosed. On page 65 of International Publication No. 2022 / 174012, regarding cGAS inhibition, "biochemical (in vitro) IC 50 value,” and on page 67 of International Publication No. WO 2022 / 174012, “Cell IC 50 Compound 5 (BBL0100455) of WO 2022 / 174012 was a) Biochemical (or enzymatic) (in vitro) IC50 of less than 100 nM 50 Compound 5 was measured to have an "enzyme IC value" of 50 nM to 100 nM in the "enzyme assay of WO 2022 / 174012." 50 "These compounds are included in "Group B" which represents "values ​​of 100-150% of the total ... b) Cellular IC lower than 1 μM 50 Compound 5 was measured to have a "cellular IC value" of <1 μM in a "THP-1 stimulated IFNβ ELISA" (the "cellular assay" of WO 2022 / 174012). 50 (See Table 3 on pages 67 and 68 of WO 2022 / 174012) It appears that these compounds are the only compounds of WO 2022 / 174012 that may have the potential to satisfy the selection criteria of the present invention, which means

[0218] However, both the biochemical / enzyme assays and the cellular assays of WO 2022 / 174012 are not identical to the respective "biochemical / enzyme assays and cellular assays" of the present invention, and therefore the measured biochemical / enzyme ICs of WO 2022 / 174012 are not identical to the respective "biochemical / enzyme assays and cellular assays" of the present invention. 50 Value and cell IC 50 The values ​​are the respective IC values ​​measured for the compounds of the present invention. 50 Therefore, compound 5 of WO 2022 / 174012 was synthesized and then tested for its pharmacological properties with respect to its efficacy in inhibiting the cGAS / STING pathway using the exact same assay used to test compounds of the present invention and described in Section 6 below.

[0219] [Table 15] As the data in Table 3 show, Compound No. 5 of WO 2022 / 174012 (BBL0100455) exhibited an acceptable biochemical / enzymatic IC of 55 nM. 50 Value (hcGAS IC 50 = 55 nM), but has a cellular IC higher than 10,000 nM 50 Value(THP1 (vir) I C 50 = 10000 nM). As a result, all of the compounds of the present invention have their biochemical / enzymatic IC 50 Although the compound is comparable to compound No. 5 of WO 2022 / 174012 in terms of cellular IC 50 These values ​​are clearly superior to compound No. 5 of WO 2022 / 174012 (all below 1000 nM for compounds of formula I, II, or III of the invention).

[0220] 5.3 Prodrugs It is known that esters of active agents with carboxylic acid groups can represent viable prodrugs, for example, can exhibit improved oral absorption / bioavailability compared to the respective active agents. Commonly used prodrugs of active agents with carboxylic acid groups include, for example, methyl esters, ethyl esters, isopropyl esters, etc. (see Beaumont et al., Current Drug Metabolism, 2003, Vol. 4, Issue 6, 461-485). Furthermore, Nakamura et al., Bioorganic & Medicinal Chem., Vol. 15, Issue 24, pp. 7720-7725 (2007) describe that N-acylsulfonamide derivatives and N-acylsulfonylurea derivatives of specific active agents with free carboxylic acid groups may also be useful prodrugs.

[0221] Additionally, experimental indications have been found that the methyl esters of the example compounds of Formula I, II, or III also represent viable prodrugs of the cGAS inhibitors of Formula I, II, or III. International Application Nos. PCT / EP2022 / 062480 and PCT / EP2022 / 062496 (both previously unpublished applications) both disclose cGAS inhibitors structurally similar to the cGAS inhibitors of the present invention, all of which also contain a carboxylic acid group attached to the pyrrolidine moiety. In both International Application Nos. PCT / EP2022 / 062480 and PCT / EP2022 / 062496, experiments have shown that methyl ester derivatives of these cGAS inhibitors having a carboxylic acid group attached to the pyrrolidine moiety act as viable prodrugs of the cGAS inhibitors having a free carboxylic acid group. Compounds P01, P02, P03, and P04 of International Application No. PCT / EP2022 / 062480 were methyl ester derivatives and putative prodrugs of Example compounds 4.04, 1.10, 1.12, and 3.14, respectively, of International Application No. PCT / EP2022 / 062480 (all possessing a free carboxylic acid group and exhibiting low biochemical IC values ​​for cGAS inhibition). 50 Value and low cell IC 50 (It was an active cGAS inhibitor with significant efficacy).

[0222] Compounds P01, P02, and P03 of International Application PCT / EP2022 / 062496 were methyl ester derivatives and putative prodrugs of Example compounds 2.12, 1.13, and 1.05, respectively, of International Application PCT / EP2022 / 062496 (all possessing a free carboxylic acid group and exhibiting low biochemical IC values ​​for cGAS inhibition). 50 Value and low cell IC 50 (It was an active cGAS inhibitor with significant efficacy). In both International Application No. PCT / EP2022 / 062480 and International Application No. PCT / EP2022 / 062496, "active cGAS inhibitors / example compounds with their free carboxylic acids" and their "respective methyl ester derivatives / putative prodrugs" were synthesized and tested for their pharmacological properties with respect to their potency in inhibiting the cGAS / STING pathway. On the other hand, this comparison of the properties of the example compounds of International Application Nos. PCT / EP2022 / 062480 and PCT / EP2022 / 062496 with their free carboxylic acids and their corresponding methyl ester derivatives / putative prodrugs allows the "biochemical IC" of the example compounds to be compared. 50 Value (hcGAS IC 50 While the "biochemical IC value" of the corresponding methyl ester derivatives / prodrugs is always around 10 nM or much lower than 10 nM, 50 value" (hcGAS IC 50 The IC values ​​of the example compounds are always extremely high, generally higher than 7000 nM. 50values ​​and on the other hand the IC of their corresponding methyl ester derivatives / prodrugs 50 Such large differences between the values ​​are consistent with the respective cellular IC values, which always remain in almost the same range between the example compounds and their corresponding prodrugs. 50 Value(THP1 (vir) I C 50 values) was not observed (see Table 4 below).

[0223] One possible explanation for this observation is that all of the example compounds have a free carboxylic acid group, which appears to be crucial for inhibiting cGAS activity, but in all of the "methyl ester derivatives / prodrugs," the carboxyl group is masked by a carboxy-methyl ester group. As a result, the methyl ester derivatives / prodrugs lose their inhibitory potency in the "in vitro human cGAS enzyme assay" (see Section 6.1 below), because in this assay there is no intracellular enzyme to cleave the carboxy-methyl ester group, and therefore the crucial free carboxylic acid group cannot be restored in the biochemical assay. Therefore, the prodrugs have very high "biochemical (in vitro) IC" in this "in vitro human cGAS enzyme assay." 50 value" (=hcGAS IC 50 ), whereas the corresponding example compounds (which originally had a free carboxylic acid group) showed low "biochemical (in vitro) IC 50 value" (=hcGAS IC 50 ) is shown.

[0224] In cellular assays (= "Human cGAS Cellular and Counter-Cellular Assays", see section 6.2 below), there are endogenous cellular enzymes that cleave the carboxy-methyl ester group. As a result, the example compounds of International Application Nos. PCT / EP2022 / 062480 and PCT / EP2022 / 062496 themselves (which already have a free carboxylic acid group) exhibit low THP1 activity. (vir) I C 50Not only do they show relatively low THP1 values, but the corresponding methyl ester derivatives / prodrugs also show relatively low THP1 values. (vir) I C 50 "Values" are shown because in this "Human cGAS Cellular Assay," the carboxy-methyl ester group of the prodrug can be cleaved by endogenous intracellular enzymes, thereby liberating "active Example Compounds with a free carboxylic acid group," which again exhibit cGAS inhibitory potency.

[0225] This explanation, together with the measurements shown in Table 4, suggests that the carboxy-methyl ester derivatives of the structurally similar Example Compounds of International Applications PCT / EP2022 / 062480 and PCT / EP2022 / 062496 do indeed appear to represent viable prodrugs of the respective Example Compounds bearing a free carboxylic acid group, which themselves have no inhibitory potency with respect to in vitro human biochemical cGAS inhibition. However, following cleavage of the carboxy-methyl ester by endogenous intracellular enzymes present in cellular assays, the "active Example Compounds" are reinstated, again demonstrating inhibitory potency with respect to the cGAS / STING pathway. Since the example compounds of formula I, II, or III of the present invention have exactly the same free carboxylic acid attached to the pyrrolidinyl moiety as the example compounds of International Application No. PCT / EP2022 / 062480 or International Application No. PCT / EP2022 / 062496, it can be expected that carboxy-methyl ester derivatives of these compounds of formula I, II, or III will also act as prodrugs.

[0227] 5. Biological experiments The activity of the compounds of the present invention can be demonstrated using the following in vitro cGAS enzyme and cellular assays: 6.1 Methods: Human cGAS Enzyme Assay (hcGAS IC 50 (in vitro) The human cGAS enzyme was incubated in the presence of 45 base pairs of double-stranded DNA to activate the enzyme and GTP and ATP as substrates. Compound activity was determined by measuring the effect of the compound on the formation of the enzymatic reaction product, cGAMP, as measured by mass spectrometry.

[0228] Enzyme preparation: Human cGAS (amino acids 1-522) with an N-terminal 6xHis tag and SUMO tag was expressed in Escherichia coli (E. coli) BL21(DE3) pLysS (Novagen) cells at 18°C ​​for 16 hours. Cells were lysed in a buffer containing 25 mM Tris (pH 8), 300 mM NaCl, 10 mM imidazole, 10% glycerol, a protease inhibitor cocktail (cOmplete™, EDTA-free, Roche), and DNase (5 μg / mL). cGAS protein was isolated by affinity chromatography on Ni-NTA agarose resin and further purified by size-exclusion chromatography using a Superdex 200 column (GE Healthcare) equilibrated in 20 mM Tris (pH 7.5), 500 mM KCl, and 1 mM TCEP. The purified protein was concentrated to 1.7 mg / mL and stored at -80°C.

[0229] Assay Method Compounds were provided as 10 mM DMSO solutions, serially diluted, and transferred to a 384-well assay plate (Greiner #781201) using an Echo acoustic dispenser. Typically, eight concentrations were used, with the highest concentration being 10 μM in the final assay volume, followed by approximately 1:5 dilution steps. DMSO concentration was set to 1% in the final assay volume. The 384-well assay plate contained 22 test compounds (columns 1-22), with columns 23 and 24 containing DMSO. After compound transfer, 15 μL of enzyme-DNA working solution (12 nM cGAS, 0.32 μM 45 base pair DNA / assay buffer, 10 mM Tris pH 7.5 / 10 mM KCl / 5 mM MgCl2 / 1 mM DTT) was added via a MultiDrop Combi dispenser to each well in columns 1 through 23. In column 24, 15 μL of assay buffer without enzyme / DNA was added as a low control. The plates were then pre-incubated at room temperature for 60 minutes.

[0230] Then, 10 μL of GTP (ThermoFisher #R0461)-ATP (Promega #V915B) mix in assay buffer was added to the assay plate (columns 1-24, final concentration 30 μM each) using a Multidrop Combi. The plates were again incubated at room temperature for 90 minutes. After incubation, the reaction was stopped with 80 μL of 0.1% formic acid in assay buffer containing 5 nM cyclic-di-GMP (Sigma #SML1228), used as an internal standard for mass spectrometry analysis. The total volume per well was 105 μL.

[0231] Rapidfire MS detection The plate was centrifuged at 4000 rpm at 4°C for 5 minutes. The RapidFire autosampler was connected to a binary pump (Agilent 1290) and a Triple Quad 6500 (ABSciex, Toronto, Canada). The system was equipped with a 10 μL loop of a C18 [12 μL bed volume] cartridge (Agilent, part number G9210A) containing 10 mM NH4Ac (aqueous) water (pH 7.4) as eluent A (pump 1 1.5 mL / min, pump 2 1.25 mL / min) and 10 mM NH4Ac (pH 7.4) in 47.5 / 47.5 / 5 (v / v / v) ACN / MeOH / HO (pump 3 1.25 mL / min) as eluent B. Aspiration time: 250 ms; load time: 3000 ms; elution time: 3000 ms; wash volume: 500 μL.

[0232] The MS was operated in positive ion mode with a HESI ion source, source temperature 550°C, curtain gas = 35, gas 1 = 65, and gas 2 = 80. Unit mass resolution in SRM mode. The following transition and MS parameters (DP: declustering voltage and CE: collision energy) were determined for cGAMP and DicGMP: Analyte: cGAMP, 675.1 / 524, DP=130, CE=30 Internal standard: cyclic-di-GMP, 690.1 / 540, DP=130, CE=30. The formation of cGAMP was monitored and assessed as a ratio to cyclic-di-GMP. Data evaluation and calculations: For data evaluation and calculation, the measurement of the low control was set as the 0% control and the measurement of the high control was set as the 100% control. 50 Values ​​were calculated using the standard 4-parameter logistic regression equation: [y = (ad) / (1 + (x / c)^b) + d], where a = low value, d = high value; x = conc M; c = IC. 50 M;b=slope

[0233] 6.2 Methods: Human cGAS cell assay and cGAMP-stimulated counter cell assay (THP1 (vir) I C 50 and THP1(cGAMP) I C 50 ) THP1-Dual™ cells (InvivoGen #thpd-nfis) expressing an IRF-dependent Lucia luciferase reporter were used as the basis for both assays. For detection of cellular cGAS activity, cells were stimulated by infection with a baculovirus (pFastbac-1, Invitrogen, no coding insert) delivering cGAS enzyme-stimulating double-stranded DNA (THP1 (vir) I C 50 measurement). In a counter assay, cells were stimulated with cGAMP (SigmaAldrich #SML1232) to activate the same pathway directly downstream of cGAS (THP1 (cGAMP) I C 50 measurement). Pathway activity was measured by DNA-stimulated cGAS enzyme activity (THP1 (vir) I C 50 Measurement of cGAMP (THP1 (cGAMP) I C 50 The activity was monitored by measuring the Lucia luciferase activity induced by the IL-1 receptor (measurement of IL-1, counter assay).

[0234] Assay Method Compounds were provided as 10 mM DMSO solutions, serially diluted, and transferred to a 384-well assay plate (Greiner #781201) using an Echo acoustic dispenser. Typically, eight concentrations were used, with the highest concentration being 10 μM in the final assay volume, followed by approximately 1:5 dilution steps. DMSO concentration was set to 1% in the final assay volume. The 384-well assay plate contained 21 test compounds (columns 1-22), with columns 23 and 24 containing DMSO. Cells cultured according to the manufacturer's conditions were harvested by centrifugation at 300g / 10 min and resuspended in fresh cell culture medium (RPMI 1640 (Gibco #A10491-01), 10% FCS (Gibco #10500), 1x GlutaMax (Gibco #35050-061), 1x Pen / Strep solution (Gibco #15140-122), 100µg / ml Normocin (InvivoGen #ant-nr), 100µg / ml Zeocin (InvivoGen #ant-zn), 10µg / ml Blasticidin S (Life Technologies #A11139-03)) and diluted to 1.66E5 cells / ml. The baculovirus solution was then added to the cells (THP1) at a 1:200 ratio (varied depending on the virus batch). (vir) I C 50 Alternatively, in the counter assay, cGAMP was added to the cells at a final concentration of 10 μM (THP1 (cGAMP) I C 50 measurement).

[0235] 30 μL of cell / virus mix was added via a Multidrop Combi dispenser to each well (5000 cells / well) of the compound plate in columns 1 to 23. In column 24, 30 μL / 5000 cells / well without virus was added as a low control. The plates were then incubated in a humidified incubator at 37°C for 18 hours. Then, 15 μL of QuantiLuc detection reagent (InvivoGen #rep-qlcg5) was added to each well using a Multidrop Combi. Immediately after addition, measurements were taken using an EnVision reader (US-luminescence reading mode). Data evaluation and calculations: For data evaluation and calculation, the measurement of the low control was set as the 0% control and the measurement of the high control was set as the 100% control. 50Values ​​were calculated using the standard 4-parameter logistic regression equation: [y = (ad) / (1 + (x / c)^b) + d], where a = low value, d = high value; x = conc M; c = IC. 50 M;b=slope

[0236] 6.3 Method: Human Whole Blood Assay (Human WB IC 50 ) To detect cellular cGAS activity, human whole blood was stimulated by transfection with double-stranded DNA, and pathway activity was monitored by measuring IFNα2α production. Assay Method Compounds were provided as 10 mM DMSO solutions, serially diluted, and transferred to a 96-well cell culture plate (Corning #3595), with each well pre-filled with 20 μl OptiMEM (Gibco, #11058-021) using an Echo acoustic dispenser. Typically, eight concentrations were used, with the highest concentration being 10 μM in the final assay volume, followed by approximately 1:5 dilution steps. The DMSO concentration was set to 0.1% in the final assay volume. The 96-well assay plate contained 10 test compounds, with control wells containing DMSO. Human whole blood was collected in parallel from three or more healthy donors (male or female, free of contraceptives and medications other than thyroxine for 7 days) as sodium citrated blood (e.g., 3.8% in Mononovettes from Sarstedt). Whole blood was kept at room temperature for a maximum of 3 hours after collection until use in the assay.

[0237] 160 μl of whole blood sample was transferred to each well of a 96-well assay plate filled with compound / OptiMEM. All assay plates were prepared in duplicate using blood from different donors. The blood plate was kept at room temperature for 60 minutes, continuously shaken at 450 rpm, and covered but not sealed. A DNA-Fugene mix (Herring DNA, Sigma Aldrich #D6898-1G, Fugene (5 x 1 mL), Promega #E2312) was prepared in OptiMEM and incubated at room temperature for 10 minutes (125 ng DNA / 20 μl and a Fugene ratio of 9.6:1). 20 μl of DNA Fugene mix was added to each well, resulting in 125 ng DNA / well / 200 μl and a Fugene ratio of 9.6:1. 20 μl of OptiMEM and 9.6:1 Fugene were added to all low control wells. After covering the assay plate with an aera seal and lid, the blood plate was kept at room temperature for 30 minutes, continuously shaken at 450 rpm, and then incubated overnight in an incubator at 37° C. without shaking for 22 hours.

[0238] For detection of IFNα-2α in human plasma, biotinylated capture antibody (antibody set IFNA2, Meso Scale Diagnostics #B21VH-3, including coating and capture antibodies) was diluted 1:17.5 in Diluent 100 (Meso Scale Diagnostics #R50AA-4) according to the manufacturer's instructions. U-Plex MSD GOLD 96-well small spot streptavidin SECTOR plates (Meso Scale Diagnostics #L45SA-5) were coated with 25 μl of diluted capture antibody. The coated plates were incubated at room temperature for 60 minutes with continuous shaking at 700 rpm. The MSD IFNα-2α plates were washed three times with 150 μl of wash buffer (1x HBSS, 0.05% Tween). Plates were blocked with 100 μl of blocking solution / well (1× HBSS containing 0.2% Tween, 2% BSA) for 60 min at room temperature and shaken continuously at 700 rpm, followed immediately by human plasma after the plates were emptied as dry as possible by dumping.

[0239] The whole blood assay plates were centrifuged at 1600 rpm for 10 minutes. 25 μl of supernatant was transferred from each whole blood plate to the corresponding IFNα-2α plate using a pipetting robot. The plates were sealed with microplate seals and again maintained at room temperature with continuous shaking at 700 rpm for 2 hours. The MSD IFNα-2α plate was then washed three times with 150 μl of wash buffer (1× HBSS, 0.05% Tween), after which 25 μl of MSD SULFO-TAG IFNα-2α antibody solution (diluted 1:100 in Diluent 3 (Meso Scale Diagnostics # R50AP-2)) was added to each well of the plate. The plate was then sealed with a microplate seal and again maintained at room temperature under continuous shaking at 700 rpm for 2 hours. Finally, the MSD IFNα-2α plate was washed three times with 150 μl of wash buffer (1×HBSS, 0.05% Tween). 150 μl of 2×Read buffer was added to each well, and the plate was immediately read on an MSD Sector S600 reader using the supplier's barcode. Data evaluation and calculations: For data evaluation and calculation, the calculation of % control for each well was based on the mean of the high control (DNA stimulated control) and the mean of the low control (unstimulated control) by using the following formula: [Count(sample) - Count(low)) / (Count(high) - Count(low))] x 100 I C 50 Values ​​were calculated using the standard 4-parameter logistic regression equation: [y = (ad) / (1 + (x / c)^b) + d], where a = low value, d = high value; x = conc M; c = IC. 50 M;b=slope

[0240] 6. Indications As can be seen, the compounds of formula I, II, or III are characterized by their range of therapeutic applications. Particular mention should be made of the use of the compounds of formula I, II, or III according to the present invention, preferably as cGAS inhibitors based on their pharmaceutical activity. While the cGAS pathway is important for host defense against invading pathogens, such as viral infections and invasion by some intracellular bacteria, cellular stress and genetic factors can also lead to the production of abnormal cellular dsDNA, for example, due to nuclear or mitochondrial leakage, which can trigger autoinflammatory responses. Consequently, cGAS inhibitors have strong therapeutic potential for use in the treatment of a variety of autoinflammatory and autoimmune diseases. An et al., Arthritis Rheumatol. 2017 Apr;69(4):800-807, reported that cGAS expression in peripheral blood mononuclear cells (PBMCs) was significantly higher in patients with the autoimmune disease systemic lupus erythematosus (SLE) than in normal controls. Targeted measurement of cGAMP by tandem mass spectrometry detected cGAMP in 15% of SLE patients tested but not in healthy or rheumatoid arthritis controls. SLE patients with cGAMP had higher disease activity than patients without cGAMP. Because elevated cGAS expression may be the result of exposure to type I interferon (IFN), the detection of cGAMP in SLE patients with increased disease activity indicates the potential involvement of the cGAS pathway in disease development.

[0241] Park et al., Ann Rheum Dis. 2018 Oct;77(10):1507-1515 also discloses the involvement of the cGAS pathway in the development of SLE. Thim-Uam et al., iScience 2020 Sep 4;23(9), 101530 (doi: 10.1016 / j.isci.2020.101530) discloses that the STING pathway mediates lupus through activation of normal dendritic cell maturation and plasmacytoid dendritic cell differentiation. Gao et al., Proc. Natl. Acad. Sci. USA 2015 Oct 20;112(42):E5699-705, describes that activation of cGAS by self-DNA leads to several autoimmune diseases, such as interferonopathies. Tonduti et al., Expert Rev. Clin. Immunol. 2020 Feb;16(2):189-198, discloses that cGAS inhibitors have particular therapeutic potential in Aicardi-Goutieres syndrome and familial lupus chilblains, which are severe lupus-like autoinflammatory immune-mediated disorders. Steiner et al., Nat Commun. 2022 Apr 28;13(1):232; doi: 10.1038 show that deficiency of coatomer complex I leads to aberrant activation of STING signaling and COPA syndrome, and that cGAS is required to drive type I IFN signaling in a COPA syndrome cell model.

[0242] Li et al. show that plasma-derived DNA-containing extracellular vesicles induce a STING-mediated proinflammatory response in dermatomyositis (Theranostics. 2021; 11(15): 7144-7158). Zhou et al. (J Clin Lab Anal. 2022 Oct; 36(10): e24631) describe a correlation between activation of the cGAS-STING pathway and muscle fiber atrophy / necrosis in dermatomyositis. Yu et al., Cell 2020 Oct 29;183(3):636-649, describes the association between mitochondrial DNA and cGAS / STING pathway activation caused by TDP-43 in amyotrophic lateral sclerosis (ALS). Ryu et al., Arthritis Rheumatol. 2020 Nov;72(11):1905-1915, also show that bioactive plasma mitochondrial DNA is associated with disease progression in certain fibrotic diseases, such as systemic sclerosis (SSc) or interstitial lung disease (ILD), progressive fibrotic interstitial lung disease (PF-ILD), and idiopathic pulmonary fibrosis (IPF). Schuliga et al., Clin. Sci. (Lond). 2020 Apr 17;134(7):889-905, describes how autologous DNA perpetuates IPF lung fibroblast senescence in a cGAS-dependent manner.

[0243] Additional scientific indications implicating other causes of fibrosis, such as nonalcoholic steatohepatitis (NASH), with the cGAS / STING pathway are described in Yu et al., J. Clin. Invest. 2019 Feb 1;129(2):546-555 and Cho et al., Hepatology. 2018 Oct;68(4): 1331-1346. Nascimento et al., Sci. Rep. 2019 Oct 16;9(1):14848, discloses that release of self-DNA and STING-dependent sensing mediate cigarette smoke-induced inflammation in mice, suggesting a link between the cGAS-STING pathway and chronic obstructive pulmonary disease (COPD). Ma et al., Sci. Adv. 2020 May 20;6(21):eaaz6717, discloses that ulcerative colitis and inflammatory bowel disease (IBD) can be suppressed by controlling cGAS-mediated inflammation. Gratia et al., J. Exp. Med. 2019 May 6;216(5):1199-1213, show that Bloom syndrome proteins suppress innate immune sensing of micronuclei by cGAS. Consequently, cGAS inhibitors have therapeutic potential in treating Bloom syndrome.

[0244] Kerur et al., Nat. Med. 2018 Jan;24(1):50-61, describes that cGAS plays an important role in non-canonical inflammasome activation in age-related macular degeneration (AMD). Visitchanakun et al., Int J Mol Sci. 2021 Oct 23;22(21):11450, show that GAS-deficient mice were less severely affected than wild-type mice in cecal ligation and puncture (CLP) and lipopolysaccharide (LPS) injection sepsis models. Wang et al., Mediators Inflamm. 2015;2015:192329, reported that cGAS is required for cell proliferation and inflammatory cytokine production in rheumatoid arthritis synovial cells. It was also reported that cGAS deficiency suppressed interferon responses, inflammatory cell infiltration, and joint swelling in a mouse model of inflammatory arthritis (Willemsen et al., Cell Rep. 2021 Nov 9;37(6):109977).

[0245] Guo et al., Osteoarthritis Cartilage. 2021 Aug;29(8):1213-1224, described that damaged DNA is an important pathological factor in osteoarthritis (OA), which may be mediated by the cGAS / STING pathway, as STING knockdown attenuates the destabilization of medial meniscus-induced OA development in mice. Mao et al., Arterioscler Thromb Vasc Biol (2017) 37(5):920-929, showed that the cGAS / STING pathway mediates endothelial inflammation in response to free fatty acid-induced mitochondrial damage in diet-induced obesity, indicating that cGAS inhibitors may also have potential in the treatment of obesity and diabetes. Kerur et al, Nat Med. 2018 Jan;24(1):50-61, describes that cGAS levels are elevated in the retinal pigment epithelium in human eyes with geographic atrophy and that cGAS drives activation of non-canonical inflammasome activation in age-related macular degeneration. cGAS promotes cellular senescence and senescence-associated secretory events (Yang et al., Proc Natl Acad Sci USA 2017 Jun 6;114:E4612-E4620). Cytoplasmic chromatin mediates inflammation in aging through cGAS / STING, and STING-null mice exhibit reduced tissue inflammation and aging (Dou et al., Nature. 2017 550:402-406). Furthermore, mutations in the STING gene are associated with healthy aging in humans, most likely through reduced inflammation-induced aging (Hamann et al., Gerontology 2019;65:145-154). Collectively, STING inhibitors reduce senescence-associated inflammation and senescent cell accumulation, leading to improvements in aging-related diseases such as aging, myopathy, and fibrosis.

[0246] Additionally, cGAS inhibitors of Formula I, II, or III also have therapeutic potential in the treatment of cancer (see Hoong et al., Oncotarget. 2020 Jul 28;11(30):2930-2955, and Chen et al., Sci. Adv. 2020 Oct 14;6(42):eabb8941). Additionally, cGAS inhibitors of Formula I, II, or III have therapeutic potential in the treatment of heart failure (Hu et al., Am. J. Physiol. Heart Circ. Physiol. 2020 Jun 1;318(6):H1525-H1537). Further scientific evidence exists regarding the correlation between Parkinson's disease and the cGAS / STING pathway (Sliter et al., Nature. 2018 Sep;561(7722):258-262) and Sjögren's syndrome and the cGAS / STING pathway (Papinska et al., J. Dent. Res. 2018 Jul;97(8):893-900). Additionally, cGAS inhibitors of Formula I, II, or III have therapeutic potential in the treatment of COVID-19 / SARS-CoV-2 infection, as shown in Di Domizio et al., Nature. 2022 Jan 19. doi: 10.1038 / s41586-022-04421-w: "The cGAS-STING pathway drives type I IFN immunopathology in COVID-19," and Neufeldt et al., Commun Biol. 2022 Jan 12;5(1):45. doi: 10.1038 / s42003-021-02983-5: "SARS-CoV-2 infection induces a pro-inflammatory cytokine response through cGAS-STING and NF-kappaB."

[0247] Additionally, cGAS inhibitors of Formula I, II, or III have therapeutic potential in treating renal inflammation and fibrosis, as shown in Chung et al., Cell Metab. 2019 30:784-799: "Mitochondrial Damage and Activation of the STING Pathway Lead to Renal Inflammation and Fibrosis," and Maekawa et al., Cell Rep. 2019 29:1261-1273: "Mitochondrial Damage Causes Inflammation via cGAS-STING Signaling in Acute Kidney Injury." Additionally, cGAS inhibitors of Formula I, II, or III have therapeutic potential in the treatment of cancer, as shown in Bakhoum et al., Nature. 2018 Jan 25;553(7689):467-472: "Chromosomal instability drives metastasis through a cytosolic DNA response," and Liu et al., Nature. 2018 Nov;563(7729):131-136: "Nuclear cGAS suppresses DNA repair and promotes tumorigenesis."

[0248] Additionally, cGAS inhibitors of Formula I, II, or III have therapeutic potential in the treatment of metabolic disorders because STING gt Animals showed reduced macrophage infiltration in adipose tissue after subchronic high-calorie diet (HFD), and STING gt and IRF3 deficiency leads to decreased blood glucose and insulin levels and weight loss (Mao et al, Arterioscler Thromb Vasc Biol, 2017;37 (5): 920-929). Furthermore, cGAS inhibitors of Formula I, II, or III have therapeutic potential in the treatment of vascular diseases, leading to vascular repair / regeneration, since release of mitochondrial DNA into the cytosol of endothelial cells activates the cGAS / STING pathway and suppresses endothelial proliferation. Furthermore, knockout of the cGAS gene restores endothelial repair / regeneration in a mouse model of inflammatory lung injury (Huang et al., Immunity, 2020, Mar 2017; 52 (3): 475-486.e5. doi: 10.1016 / j.immuni.2020,02.002). Additionally, cGAS inhibitors of Formula I, II, or III have therapeutic potential in the treatment of age-related and obesity-related cardiovascular disease (Hamann et al, Immun Ageing, 2020, Mar 14; 17: 7; doi: 10.1186 / s12979-020-00176-y.eCollection 2020).

[0249] As a result, the compounds of Formula I, II, or III as cGAS inhibitors can be used in the treatment of autoinflammatory and autoimmune diseases such as systemic lupus erythematosus (SLE), interferonopathy, Aicardi-Goutieres syndrome (AGS), COPA syndrome, familial lupus chilblains, age-related macular degeneration (AMD), amyotrophic lateral sclerosis (ALS), inflammatory bowel disease (IBD), chronic obstructive pulmonary disease (COPD), Bloom's syndrome, Sjogren's syndrome, rheumatoid arthritis, and Parkinson's disease.
