Description

Detailed Description of the Invention

[0001] The present invention relates to novel inhibitors of transglutaminase, particularly transglutaminase 2, methods for their synthesis, and their use for the prevention and treatment of diseases associated with transglutaminase, particularly transglutaminase 2.

[0002] [Background of the Invention] Transglutaminase is part of the class of transferases and, according to the EC nomenclature, is precisely designated as "protein-glutamine:amine γ-glutamyltransferase" (EC 2.3.2.13). Transglutaminase links the ε-amino group of the amino acid lysine to the γ-glutamyl group of the amino acid glutamine, forming an isopeptide bond while releasing ammonia. In the absence of a suitable amine and / or under certain conditions, deamidation of glutamine occurs, and as a result, the corresponding glutamic acid can be produced.

[0003] Furthermore, transglutaminase plays an important role in many therapeutic fields such as cardiovascular diseases (thrombosis and atherosclerosis), autoimmune diseases (celiac disease, Duhring-Brocq-disease, gluten ataxia), neurodegenerative diseases (Alzheimer's disease, Parkinson's disease, Huntington's disease), skin diseases (ichthyosis, psoriasis, acne), etc., as well as in wound healing and inflammatory diseases (e.g., tissue fibrosis) (J.M. Wodzinska, Mini-Reviews in medical chemistry, 2005, 5, 279-292).

[0004] However, celiac disease, gluten intolerance disease, is one of the most important indications. Celiac disease is characterized by chronic inflammation of the small intestine mucosa. In susceptible patients, after ingestion of gluten-containing foods, the intestinal epithelium is continuously disrupted, resulting in a decrease in nutrient absorption, which again has a great impact on affected patients and is associated with symptoms such as weight loss, anemia, diarrhea, nausea, vomiting, loss of appetite, and fatigue. These findings have created a great need for the development of drugs for the treatment of celiac disease and other diseases associated with tissue transglutaminase (transglutaminase 2, TG2, tTG). Tissue transglutaminase is a central element during the onset of the disease. The endogenous enzyme catalyzes the deamidation of gluten / gliadin in the small intestine mucosa, thus causing an inflammatory reaction. Therefore, inhibitors of tissue transglutaminase are suitable for use as active agents for drug treatment.

[0005] Another very important group of indications for tissue transglutaminase inhibitors are fibrotic diseases. Fibrotic diseases are characterized by the accumulation of cross-linked extracellular matrix proteins. Diabetic nephropathy, cystic fibrosis, idiopathic pulmonary fibrosis, renal fibrosis, and liver fibrosis belong to the most important fibrotic diseases to be addressed using the disclosed compounds.

[0006] US9,434,763 B2 discloses pyridinone derivatives having a reaction group (warhead) containing at least one acceptor-substituted double bond, such as a Michael system, as irreversible transglutaminase inhibitors. Alkylacetamide and arylacetamide pyridinones showed inhibitory activity in the nanomolar range (IC 50 ) with respect to tissue transglutaminase TG2.

[0007] Tse et al. (J. Med. Chem. 2020, 63, 11585 - 11601) modified the solubility and metabolic stability of the compound with an antimalarial triazolopyrazine compound Herein, we report on the substitution of phenyl residues with non-classical biological equivalents, such as cubane and bicyclo[1.1.1]pentane (BCP). We further evaluated the in vitro antiplasmodial activity of biologically equivalent modified triazolopyrazines against the 3D7 strain of Plasmodium falciparum. Substitution of phenyl with saturated heterocyclic residues of biological equivalents results in a complete loss of activity. Adamantyl residues, and other hydrocarbon-caged derivatives, resulted in up to 2- to 9-fold lower efficacy compared to the corresponding phenyltriazolopyrazine compounds. In contrast, higher efficacy was achieved by replacing phenyl with closo-1,2- and 1,7-carborane isomers. We conclude that the effect of non-classical biological equivalent substitution on biological properties cannot be accurately predicted, and that a range of possible biological equivalents should first be tested to identify the appropriate substitution to achieve the desired properties of a given molecule.

[0008] Subbaiah et al. (J. Med. Chem. 2021, 64, 19, 14046-14128) reported on the biological equivalents of the phenyl ring in lead optimization and drug design. It is noted that substitution of the phenyl ring of biological equivalents with heterocyclic and carbocyclic moieties can lead to improvements in efficacy, solubility, and metabolic stability while reducing lipophilicity, plasma protein binding, phospholipidosis potential, and inhibition of cytochrome P450 enzymes and hERG channels. However, this effect strongly depends on the properties of the compound itself and the target being addressed.

[0009] US11,072,634 B2 discloses reversible transglutaminase inhibitors containing an aldehyde, ketone, α-ketoaldehyde, α-ketoketone, α-ketoacid, α-ketoester, α-ketoamide or halogenomethyl ketone as a warhead. The inhibitors showed inhibitory activity in the nanomolar and micromolar ranges (IC 50 ) against tissue transglutaminase TG2.

[0010] The object of the present invention is to provide novel, possibly reversible inhibitors of transglutaminase, particularly transglutaminase 2, a method for synthesizing said inhibitors, and some uses of these inhibitors.

[0011] Said object is solved by the technical teaching of the independent claims. Further advantageous embodiments, aspects and details of the present invention are apparent from the dependent claims, the description and the examples.

[0012] Surprisingly, it has been shown that reversible inhibitors having a chemical warhead disclosed herein effectively inhibit transglutaminases, including tissue transglutaminase called transglutaminase 2 or TG2. In this specification, these terms are used synonymously.

[0013] Preferably, the warhead moiety is particularly selected from reversible warheads such as α-ketoamides. The compounds of the present invention act as selective inhibitors of transglutaminase 2.

[0014] To demonstrate the inventiveness of the compounds of the present application, reference compounds were synthesized and tested in comparison with the most similar compounds in the present application. Those skilled in the art may notice compound A8 from our patent US9,434,763B2, which we introduce as Ref.3 to emphasize the inventiveness and preferred features of the compounds described in the claims. From US9,434,763B2, it is clear that the aromatic moiety (C-terminus) limits the effectiveness of these compounds (compared to A1, A8, A37, A44, A47). In a remarkable contrast, as shown by more potent compounds (A28, A29, A59, A61, A63, A67, A68, A79), a branched alkyl moiety is highly preferred.

[0015] ​To illustrate the advantages of the branched alkyl moiety compared to the aromatic moiety, we refer to reference compounds Ref.2 (ZED1227, US9,434,763B2) and Ref.3 (A8, ZED1047). Inhibition data were determined as described using the classical fluorescent amidotransferase assay (dansylcadaverine uptake into methylated casein, DCC-assay) [Buchold, C.; Hils, M.; Gerlach, U.; Weber, J.; Pelzer, C.; Heil, A.; Aeschlimann, D.; Pasternack, R. Features of ZED1227: The First-In-Class Tissue Transglutaminase Inhibitor Undergoing Clinical Evaluation for the Treatment of Celiac Disease. Cells 2022, 11, 1667. https: / / doi.org / 10.3390 / cells11101667]. Casein is one of the best-known high molecular weight (24 kDa) protein substrates for transglutaminase. The IC 50 value of Ref.3 (A8) published in US9,434,763 B2 is dependent on a fluorescence-generating isopeptidase assay and should be noted that it cannot be compared with the current data. The Ref.2 (IC 50 = 53 nM) measured in the DCC-assay is 80-fold more potent compared to Ref.3 (IC 50 = 4,268 nM).

[0016] Therefore, a person skilled in medicinal chemistry would select a branched alkyl moiety as the lead structure, excluding aromatic moieties such as, for example, phenyl groups. It is a well-known fact that a bridged cycloalkyl group is a non-classical biological equivalent of a phenyl group. By substituting the phenyl group in A8 with, for example, an adamantyl group, a person skilled in the art would expect similar physicochemical or biochemical properties without much effort. Since the aromatic moiety is clearly not preferred, a bridged cycloalkyl group would not be considered to improve the compound.

[0017] This is further supported by additional reference compounds. ZED3641 (disclosed in Ref. 1, US11,072,634B2; Ref. 2, a reversibly acting α-ketomethylamide analogue of ZED1227) is approximately 15 times more potent compared to Ref. 4 (see comparison in Table 1). Ref. 4 is similar to compound A8 disclosed in US9,434,763B2 with respect to the skeleton, and once again demonstrates the superiority of the branched alkyl moiety compared to an aromatic derivative combined with a reversible acting warhead.

[0018] However, surprisingly, as shown in Table 1, substitution of the preferred branched alkyl moiety with a bridged cycloalkyl group further significantly improves the effectiveness of the compound. Therefore, we evaluate that the bridged cycloalkyl group as disclosed is an excellent inventive method.

[0019] In summary, the compounds of the present invention evaluated as "A" show approximately 30 times higher effectiveness compared to Ref. 3 (compare with A8, Table 1). Furthermore, compounds having activities evaluated as "B" or "C" are even more preferred than Ref. 3 (A8) (lower IC 50 value). Since peripheral ligands affect physicochemical or biochemical properties, these compounds can also be considered inventive. Therefore, depending on the application, compounds with weak effects can also have high value.

[0020] Accordingly, the present invention relates to a compound of general formula (I), or a diastereomer, enantiomer, mixture of diastereomers, mixture of enantiomers, racemate, solvate, hydrate, or pharmaceutically acceptable salt of a compound of general formula (I): wherein:

[0039] The inventors have shown that the reversible inhibitors of formula (I) disclosed herein having the bridged bicyclic residue R 3 exhibit an increase in efficacy over the compounds of the prior art. In particular, the compounds of the present invention are demonstrated herein to have improved inhibitory activity compared to known compounds having an aromatic moiety R 3 in place of the bridged bicyclic residue. To demonstrate the inventiveness of the compounds of the present application, known compounds from US9,434,763B2 and US11,072,634B2 (Reference 1 (E16 from US11,072,634 B2), Reference 3 (A8 from US9,434,763B2), and Reference 4) were synthesized and tested as reference compounds against the most similar compounds of the present application.

[0040] Within the scope of the present application, the inhibition data was determined using the classical fluorescence amino group translocation assay (dansylcadaverine incorporation into methylated casein, DCC-assay) as described in Buchold et al. [Buchold, C.; Hils, M.; Gerlach, U.; Weber, J.; Pelzer, C.; Heil, A.; Aeschlimann, D.; Pasternack, R. Features of ZED1227: The First-In-Class Tissue Transglutaminase Inhibitor Undergoing Clinical Evaluation for the Treatment of Celiac Disease. Cells 2022, 11, 1667. https: / / doi.org / 10.3390 / cells11101667]. Casein is one of the best-known high molecular weight (24 kDa) protein substrates for transglutaminase. The inhibition data of the compounds of the present invention was compared with the inhibition of the compounds disclosed in US 9,434,763 B2, in particular Compound A8 shown herein as Reference 3. It should be noted that the IC e values of Compound A8 disclosed in US 9,434,763 B2 and E16 from US 11,072,634 B2 depend on the fluorescence-generating isopeptidase assay and cannot be compared with the current data. Therefore, the compounds of the present invention of formula (I) evaluated as "A" showed approximately 100% higher efficacy compared to Ref. 3 (A8). The same argument applies to Ref. 4. Ref. 4 also shows that the aromatic moiety of this reference compound strongly reduces the inhibitory activity against TG2. 50

[0041]

[0042] ​​Thus, one of ordinary skill in the art would exclude aromatic moieties, such as a phenyl group. It is well known that a bridged cycloalkyl group is a non-classical biological equivalent of a phenyl group. Substitution of the phenyl group in A8 with, for example, an adamantyl group, one of ordinary skill in the art would expect similar physicochemical or biochemical properties, barring effort. Since the aromatic moiety is clearly not preferred, a bridged cycloalkyl group is not considered to improve the compound.

[0043] Surprisingly, the compounds of the present invention demonstrate that the bridged cycloalkyl group improves the potency of the compound by several orders of magnitude compared to the aromatic reference compound. Thus, we consider the disclosed bridged cycloalkyl group to be an excellent inventive method.

Suitable lubricants include metal salts of stearic acid such as magnesium stearate, calcium stearate, or potassium stearate; stearic acid; waxes having a high melting point; and water-soluble lubricants such as sodium chloride, sodium benzoate, sodium acetate, sodium oleate, polyethylene glycol, and D,L-leucine. Due to the fact that the lubricant must be present on the surface of the granules and between the granules and the parts of the tablet press, the lubricant is typically added during the last step before compression. The amount of lubricant in the composition can range from about 0.2% to about 5% by weight of the total composition, preferably from about 0.5% to about 2% by weight, and more preferably from about 0.3% to about 1.5% by weight.

[0262] The lubricant is a substance that prevents solidification and improves the flow characteristics of the granules, thus making the flow smooth and uniform. Suitable lubricants include silicon dioxide and talc. The amount of lubricant in the composition can range from about 0.1% to about 5% by weight of the total composition, preferably from about 0.5% to about 2% by weight.

[0263] The coloring agent is an adjuvant that colors the composition or dosage form. The adjuvant can include a food-quality coloring agent adsorbed to a suitable adsorbing means such as, for example, clay or aluminum oxide. The amount of coloring agent used can vary from about 0.1% to about 5% by weight of the composition, and preferably from about 0.1% to about 1% by weight.

[0264] As used herein, a "pharmaceutically effective amount" of a transglutaminase inhibitor is an amount or activity effective to achieve a desired physiological result in either cells treated in vitro or patients treated in vivo. Specifically, a pharmaceutically effective amount is an amount sufficient to inhibit one or more of the clinically defined pathological processes associated with transglutaminase 2 for a specified period of time. The effective amount can vary according to the particular compound of formula (I) and further depends on a plurality of factors and conditions related to the patient being treated and the severity of the disease. For example, when the inhibitor is administered in vivo, among the data to be considered are factors such as the patient's age, weight, health status, etc., as well as dose-response curves and data on toxicity obtained from preclinical animal experiments. When the inhibitor in the form of a compound of formula (I) described herein is brought into contact with cells in vivo, a plurality of preclinical in vitro studies will be designed to determine parameters such as absorption, half-life, dosage, toxicity, etc. Determining the pharmaceutically effective amount for a given pharmaceutically active ingredient is part of the ordinary skill of a person skilled in the art.

Inhibitory Effect of the Compounds According to the Present Invention Transglutaminase Assay To determine the effectiveness of inhibitors against tissue transglutaminase, the incorporation of dansylcadaverine into dimethylcasein (product T036 from Zedira, Lorand et al., Anal Biochem, 1971, 44:221-31) was measured using recombinant human transglutaminase 2 (product T022 from Zedira).

[0543] Tissue transglutaminase is diluted with buffer (50 mM Tris-HCl, 7.5 mM CaCl2, 150 mM NaCl, pH = 7.4). The final concentration of TG2 in the assay is 10 nM.

[0544] A 10 mM inhibitor stock solution is prepared in DMSO, and serial 1:2-fold dilution series are similarly prepared in DMSO. Subsequently, each initial dilution is diluted 1:50-fold with buffer (50 mM Tris-HCl, 7.5 mM CaCl2, 150 mM NaCl, pH = 7.4) to generate the final working dilutions containing 2% (v / v) DMSO.

[0545] 15 μl of the inhibitor working dilution is added to each well of a 96-well microtiter plate. As a control, 15 μl of a 2% (v / v) DMSO solution prepared with the above buffer is added to each well.

[0546] Immediately before starting the assay, 600 μl of the transglutaminase working solution is added to 11.4 ml of assay buffer (50 mM Tris- HCl, 10 mM CaCl2, 10 mM glutathione, 2.5% glycerol, 16.7 μM dansylcadaverine, 4 μM N,N-dimethylcasein, 200 mM NaCl, pH = 8.0). 285 μl of this reaction mixture is added to each well containing the inhibitor.

[0547] The increase in fluorescence is measured at 37 °C for 30 min at λ ex = 330 nm and λem Measure using 500 nm. Calculate the slope of the fluorescence increase between 20 and 30 minutes for the determination of the IC 50 value (the inhibitor concentration at which 50% of the initial activity is inhibited).

[0548] The analysis of enzyme activity is performed by calculating the slope of the increase in fluorescence intensity. The IC 50 value is calculated by plotting the enzyme activity (as a percentage from a control containing 2% DMSO instead of the inhibitor) against the inhibitor concentration. The IC 50 is defined as the inhibitor concentration that inhibits 50% of the initial enzyme activity.

[0549] The inhibitory activity of the compounds of the present invention against tissue transglutaminase (TG2) is shown in Table 1 below using the IC 50 value.

LogD values of the compounds of the present invention To classify the compounds of the present invention according to their lipophilicity, the LogD value (partition coefficient) was determined using a well-established shake flask method, and the partitioning of the compounds between octanol and phosphate-buffered saline (PBS, pH 7.4) was measured by HPLC.

[0555] Compounds with medium lipophilicity (LogD value of 0 - 3) are usually favorable for oral absorption and have a balance between solubility and permeability. However, advanced formulation of compounds may improve the oral bioavailability for highly lipophilic compounds.
