Description

[0001] This invention relates to substituted pyrazolylpiperidine carboxylic acids, their salts, methods of preparation thereof, and their use in the preparation of medicaments for the treatment and / or prevention of diseases, particularly cardiovascular and cardiac diseases, preferably heart failure with reduced and preserved ejection fraction (HFrEF, HFmrEF, and HFpEF); hypertension (HTN); peripheral artery disease (PAD, PAOD); cardiorenal and kidney diseases, preferably chronic kidney disease and diabetic kidney disease (CKD and DKD); cardiopulmonary and pulmonary diseases, preferably pulmonary hypertension (PH); and other diseases, preferably neurodegenerative diseases and various forms of dementia, fibrotic diseases, systemic sclerosis (SSc), sickle cell disease (SCD), and wound healing disorders such as diabetic foot ulcers (DFU).

[0002] Furthermore, the same pathophysiological mechanisms described above are also effective when transfusing blood to patients with indications for transfusion (e.g., by increasing the concentration of free hemoglobin through storage, etc.).

[0003] Furthermore, in the future, the combination of sGC activators with synthetic hemoglobin oxygen carriers may alleviate the side effects caused by reduced NO availability that have been found to date [Weiskopf, Anaesthesia & Analgesia, 110:3; 659-661, 2010], thus allowing for clinical application.

[0004] Cyclic guanosine monophosphate (cGMP) is one of the most important cell signaling systems in mammalian cells. It forms the NO / cGMP system together with nitric oxide (NO), which transmits hormones and mechanotransmitters released by endothelial cells. Guanylate cyclases catalyze the biosynthesis of cGMP from guanosine triphosphate (GTP). Currently disclosed representatives of this family can be divided into two categories based on structural characteristics and ligand type: granular guanylate cyclases stimulated by natriuretic peptide and soluble guanylate cyclases stimulated by NO. Soluble guanylate cyclases consist of two subunits, and each heterodimer likely contains a heme, which is part of the regulatory site. The latter is crucial for the activation mechanism. NO can bind to the iron atom of heme, thereby significantly increasing enzyme activity. In contrast, formulations without heme cannot be stimulated by NO. Carbon monoxide (CO) can also attach to the central iron atom of heme, but the stimulatory effect of CO is significantly less than that of NO.

[0005] By producing cGMP and regulating the phosphodiesterases, ion channels, and protein kinases generated therefrom, guanylate cyclases play a crucial role in various physiological processes, particularly in smooth muscle cell relaxation and proliferation, platelet aggregation and adhesion, neuronal signaling, and the pathogenesis of diseases resulting from impaired processes. Under pathophysiological conditions, the NO / cGMP system may be inhibited, which may lead to, for example, hypertension, platelet activation, increased cell proliferation and fibrosis, endothelial dysfunction, atherosclerosis, angina pectoris, heart failure, thrombosis, stroke, and myocardial infarction.

[0006] A promising approach to treat such diseases that is NO-independent and aims to affect the cGMP signaling pathway in the organism is one that is highly efficient and has few anticipated side effects.

[0007] Compounds such as organic nitrates, which act based on NO, have so far been specifically used for the therapeutic stimulation of soluble guanylate cyclase. NO is produced by biotransformation and activates soluble guanylate cyclase by attaching to the central iron atom of heme. In addition to side effects, the development of tolerance is one of the major drawbacks of this treatment [OVEvgenov et al., Nature Rev. Drug Disc. 5 (2006), 755].

[0008] In recent years, substances that can directly stimulate soluble guanylate cyclase (sGC) without pre-releasing NO have been discovered. The indazole derivative YC-1 is the first NO-independent but heme-dependent sGC stimulator [Evgenov et al., ibid.]. Based on YC-1, other substances with stronger potency than YC-1 and no associated inhibitory activity on phosphodiesterase (PDE) have been discovered. This led to the discovery of pyrazolopyridine derivatives BAY 41-2272, BAY 41-8543, BAY 63-2521, and BAY 102-1189. These compounds, along with the recently published structurally different substances CMF-1571 and A-350619, form a new class of sGC stimulators [Evgenov et al., ibid.]. A common characteristic of this class of substances is their NO-independent and selective activation of heme-containing sGCs. Furthermore, based on the stability of the nitroso-heme complex, the sGC stimulators have a synergistic effect with NO binding on sGC activation. The exact binding site of sGC stimulants on sGC remains controversial. If the heme group is removed from soluble guanylate cyclase, the enzyme still retains detectable basal catalytic activity, i.e., it continues to form cGMP. None of the aforementioned stimulants can stimulate the remaining basal catalytic activity of heme-free enzymes [Evgenov et al., ibid.].

[0009] Furthermore, NO- and heme-independent sGC activators were discovered, with BAY 58-2667 being the prototype of such activators. These substances share the characteristic that, when bound to NO, they have only an additive effect on enzyme activation, and the activation of oxidases or heme-free enzymes is significantly higher than that of heme-containing enzymes [Evgenov et al., ibid.; JPStasch et al., Br. J. Pharmacol. 136 (2002), 773; JPStasch et al., J. Clin. Invest. 116 (2006), 2552]. Spectroscopic studies showed that BAY 58-2667 replaces the oxidized heme group, which is only weakly attached to sGC due to the weakening of the iron-histidine bond. The study also indicated that the characteristic sGC heme-binding motif Tyr-x-Ser-x-Arg is essential for both the interaction of the negatively charged propionic acid with the heme group and the effect of BAY 58-2667. In this context, it is assumed that the binding site of BAY 58-2667 on sGC is the same as the binding site of heme [JPStasch et al., J.Clin.Invest. 116 (2006), 2552].

[0010] The sGC activator Runcaciguat (Hahn et al., Drugs Future 43 (2018), 738, WO 2012 / 139888) is currently undergoing clinical development by BAYER (https: / / www.clinicaltrials.gov / NCT04507061). Our understanding of the redox balance of sGC in health and disease is limited. Therefore, the therapeutic potential of sGC activators is not fully understood. However, since oxidative stress can provide sGC activators of heme-free sGC enzymes, sGC activators may have broader therapeutic potential, but this potential remains to be further identified and confirmed in the future.

[0011] The compounds described in this invention can now also activate heme-free soluble guanylate cyclases. This is also supported by the fact that, firstly, these novel activators do not synergize with NO on heme-containing enzymes, and secondly, their effects cannot be blocked by the heme-dependent inhibitor of soluble guanylate cyclase, 1H-1,2,4-oxadiazolo[4,3-a]quinoxaloline-1-one (ODQ), but can be enhanced by this inhibitor [see OVEvgenov et al., Nature Rev. Drug Disc. 5 (2006), 755; JPStasch et al., J. Clin. Invest. 116 (2006), 2552].

[0012] In WO 2012 / 058132, substituted pyrazolopyridine carboxylic acids are disclosed as sGC activators. These compounds do indeed possess a heteroaryridine moiety linking the pyrazolopyridine carboxylic acid to the remainder of the molecule, compared to the compounds of the present invention. Furthermore, the pyridine nitrogen has a different position than the piperidine nitrogen in the compounds of the present invention. However, in preclinical pharmacokinetic models, these compounds only exhibit general pharmacokinetic characteristics, such as moderate clearance (CL) and moderate half-life and mean residence time (MRT) after intravenous (iv) administration.

[0013] Therefore, one object of the present invention is to provide novel sGC activator compounds for the treatment and / or prevention of diseases in humans and animals, particularly cardiovascular and cardiac diseases, preferably heart failure with reduced and preserved ejection fraction (HFrEF, HFmrEF, and HFpEF), hypertension (HTN), peripheral artery disease (PAD, PAOD), cardiorenal and renal diseases, preferably chronic kidney disease and diabetic kidney disease (CKD and DKD), cardiopulmonary and pulmonary diseases, preferably pulmonary hypertension (PH), and other diseases, preferably neurodegenerative diseases and various forms of dementia, fibrotic diseases, systemic sclerosis (SSc), sickle cell disease (SCD), and wound healing disorders such as diabetic foot ulcers (DFU). These compounds exhibit favorable pharmacokinetic behavior, possess good pharmacological activity characteristics, and beneficial physicochemical properties (e.g., solubility).

[0014] Surprisingly, certain substituted pyrazolylpiperidine carboxylic acids and their corresponding salts have been found to be highly efficient sGC activators, exhibiting favorable pharmacokinetic behavior and beneficial physicochemical properties (e.g., solubility).

[0015] This invention provides compounds of formula (I), their salts, their solvates, and solvates of their salts.

[0542]

[0543]

[0544] The compounds of this invention have important pharmacological properties and can be used for the prevention and treatment of diseases in humans and animals.

[0545] The compounds of this invention are potent activators of soluble guanylate cyclase. These compounds induce vasodilation, inhibit platelet aggregation, lower blood pressure, and increase coronary and renal blood flow. These effects are mediated by direct, heme-independent activation of soluble guanylate cyclase and an increase in intracellular cGMP.

[0546] Furthermore, the compounds of the present invention have favorable pharmacokinetic properties, particularly in terms of their bioavailability and / or duration of action after intravenous or oral administration.

[0547] Compared to compounds disclosed in the prior art (WO 2012 / 058132, e.g., Example 174), the compounds of the present invention exhibit superior pharmacokinetic (PK) properties (see Experimental Section, Tables 3-4). The examples shown in the present invention exhibit lower plasma clearance (CL) in rats compared to the prior art compounds disclosed as Example 174 in WO 2012 / 058132. 血浆 and the resulting higher exposure levels (AUC) 标准 The half-life and mean residence time (MRT) of most of the embodiments were within a comparable range after intravenous (iv) administration. However, Example 20 showed a longer half-life and mean residence time (MRT). Following oral (po) administration in rats (see Experimental Section, Table 4), most of the embodiments (except Example 19) did indeed show equivalent to higher exposures (AUC) compared to the prior art compound disclosed as Example 174 in WO 2012 / 058132. 标准 ).

[0548] The compounds of this invention possess an unpredictable and useful pharmacological activity spectrum and favorable pharmacokinetic behavior, particularly with adequate blood exposure above the minimum effective concentration within a given dosing interval after oral administration. This characteristic results in an increased peak-to-trough ratio (the quotient of the maximum and minimum concentrations) within a given dosing interval, which has the advantage of allowing the compound to be administered at less frequency and significantly lower doses to achieve its effect. They are compounds that activate soluble guanylate cyclase.

[0726] The present invention further provides a medicament comprising at least one compound of the present invention, typically with one or more inert, non-toxic, pharmaceutically suitable adjuvants, and provides use of the medicament for the aforementioned purposes.

[0727] The compounds of the present invention can act systemically and / or locally. Therefore, they can be administered in suitable ways, such as via oral, parenteral, pulmonary, nasal, sublingual, tongue, buccal, rectal, dermal, transdermal, conjunctival, or ocular routes, or as implants or scaffolds.

[0728] The compounds of the present invention can be administered in a manner suitable for these routes of administration.

[0729] Suitable forms of administration for oral administration are those that function according to the prior art, which rapidly and / or in an improved manner release the compound of the invention, and contain the compound of the invention in crystalline and / or amorphous and / or dissolved form, such as tablets (uncoated or coated tablets, for example having an anti-gastric juice or slow-dissolving or insoluble coating that controls the release of the compound of the invention), tablets or films / capsules that rapidly disintegrate in the oral cavity, films / lyophilized forms or capsules (e.g., hard gelatin capsules or soft gelatin capsules), sugar-coated tablets, granules, pills, powders, emulsions, suspensions, aerosols, or solutions.

[0730] Parenteral administration can bypass absorption steps (e.g., intravenous, intra-arterial, intracardiac, intraspinal, or intralumbar) or include absorption steps (e.g., intramuscular, subcutaneous, intradermal, percutaneous, or intraperitoneal). Suitable forms of administration for parenteral administration include injectable and infusion formulations in the form of solutions, suspensions, emulsions, lyophilized forms, or sterile powders.

[0731] For other routes of administration, suitable examples are inhalable drug forms (including powder inhalers, nebulizers), nasal drops, solutions or sprays, tablets, films / capsules or capsules for tongue, sublingual or oral administration, suppositories, ear or eye preparations, vaginal capsules, aqueous suspensions (lotions, shaken mixtures), lipophilic suspensions, ointments, creams, transdermal therapy systems (e.g., patches), emulsions, creams, foams, powders, implants or stents.

[0732] Oral or parenteral administration is preferred, especially oral and intravenous administration.

[0733] The compounds of the present invention can be converted into the above-described dosage forms. This can be accomplished in a manner known per se by mixing with inert, non-toxic, pharmaceutically suitable excipients. These excipients include carriers (e.g., microcrystalline cellulose, lactose, mannitol), solvents (e.g., liquid polyethylene glycol), emulsifiers and dispersants or wetting agents (e.g., sodium dodecyl sulfate, polysorbate oleate), binders (e.g., polyvinylpyrrolidone), synthetic and natural polymers (e.g., albumin), stabilizers (e.g., antioxidants such as ascorbic acid), dyes (e.g., inorganic pigments such as iron oxide), and flavoring and / or taste-enhancing agents.

[0734] Generally, it has been found that, in the case of parenteral administration, a dosage of about 0.001 to 1 mg / kg body weight, preferably about 0.01 to 0.5 mg / kg body weight, is advantageous for obtaining effective results. In the case of oral administration, the dosage is about 0.01-100 mg / kg body weight, preferably about 0.01-20 mg / kg body weight, and most preferably 0.1-10 mg / kg body weight.

[0735] However, deviations from the prescribed dosage may be necessary in appropriate circumstances, particularly based on body weight, route of administration, individual response to the active compound, the nature of the formulation, and the time or interval of administration. For example, in some cases, less than the minimum dosage mentioned above may be sufficient, while in others, the mentioned upper limit must be exceeded. In cases involving large doses, it is recommended to divide these medications into several individual doses throughout the day.

[0736] The total amount of active ingredient to be administered typically ranges from about 0.001 mg / kg body weight to about 200 mg / kg body weight per day, preferably from about 0.01 mg / kg body weight to about 50 mg / kg body weight per day, and more preferably from about 0.01 mg / kg body weight to about 20 mg / kg body weight per day. Clinically useful dosing schedules range from once or three times daily to once every four weeks. Furthermore, "drug holidays," i.e., periods during which patients do not take the medication, may be beneficial for the overall balance between pharmacological effects and tolerability. A unit dose may contain from about 0.5 mg to about 1500 mg of active ingredient and may be administered once or more or less daily. For injectable administration, including intravenous, intramuscular, subcutaneous, and parenteral administration, as well as administration using infusion techniques, the average daily dose is preferably from 0.01 to 200 mg / kg body weight. For rectal administration, the average daily dose is preferably from 0.01 to 200 mg / kg body weight. For vaginal administration, the average daily dose is preferably from 0.01 to 200 mg / kg body weight. The preferred average daily topical administration regimen is 0.1 to 200 mg, administered 1 to 4 times daily. The preferred transdermal concentration is the concentration required to maintain a daily dose of 0.01 to 200 mg / kg. The preferred average daily inhalation administration regimen is 0.01 to 100 mg / kg of total body weight.

[0737] Of course, the specific initial and continuous dosing regimen for each patient will vary depending on the nature and severity of the condition as determined by the attending physician, the activity of the specific compound used, the patient's age and general condition, the timing of administration, the route of administration, the drug excretion rate, and the combination of drugs. The desired treatment modality and dosage of the compounds of the present invention, or their pharmaceutically acceptable salts or esters, or combinations thereof, can be determined by those skilled in the art through conventional treatment trials.

[0738] However, it may be necessary to deviate from the prescribed amount, depending on body weight, route of administration, individual response to the active substance, type of formulation, and the time or interval of administration. Therefore, in some cases, using less than the minimum amount mentioned above may be sufficient, while in others, the prescribed upper limit must be exceeded. When administering larger doses, it is recommended to divide these medications into several separate doses throughout the day.

[0739] According to another embodiment, the compound of formula (I) of the present invention is administered orally once, twice, or three times daily. According to another embodiment, the compound of formula (I) of the present invention is administered orally once or twice daily. According to another embodiment, the compound of formula (I) of the present invention is administered orally once daily. For oral administration, a rapid-release or modified-release formulation may be used.

[0740] Unless otherwise stated, all percentages in the following tests and examples are weight percentages; parts are parts by weight. Solvent ratios, dilution ratios, and concentration data for liquid / liquid solutions are based on volume in each case. “w / v” means “weight / volume”. For example, “10% w / v” means that 100 ml of solution or suspension contains 10 g of substance.

[0743] NMR peak shapes are described according to their appearance in the spectrum, without taking into account possible higher-order effects.

[0744] The selected compound 1 H-NMR data with 1 The peaks are listed in the form of a H-NMR peak list. For each signal peak, the δ value is given in ppm, followed by the signal intensity in parentheses. δ value-signal intensity pairs for different peaks are separated by commas. Therefore, a peak list is described in a general form: δ1 (intensity 1), δ2 (intensity 2), ..., δ i (strength i ), ..., δ n (strength n ).

[0745] In a printed NMR spectrum, the intensity of a sharp signal is related to the signal height (in cm). When compared to other signals, this data can be correlated with the actual ratio of signal intensity. In the case of a wide signal, more than one peak or signal center and its relative intensity are shown compared to the strongest signal displayed in the spectrum. 1 The H-NMR peak list is similar to the classic one. 1 H-NMR readings, therefore, typically contain all the peaks listed in the classical NMR interpretation. Furthermore, similar to classical...1 The H-NMR spectrum and peak list can display the solvent signal, the signal originating from the enantiomers of the title compound (which is also the subject of this invention), and / or impurity peaks. The peaks of the enantiomers and / or impurities typically show lower intensity compared to the peaks of the title compound (e.g., purity >90%). These enantiomers and / or impurities may be typical of a particular manufacturing method, and therefore their peaks may help identify the reproducibility of the manufacturing method of this invention based on the "byproduct fingerprint." Experts who calculate the title compound peaks using known methods (MestReC, ACD simulation, or expected values ​​evaluated empirically) can separate the title compound peaks as needed, optionally using additional intensity filters. Such operation is similar to classical... 1 Peak-picking in H-NMR interpretation. A detailed description of NMR data recorded in peak list form can be found in the publication "Citation of NMR Peaklist Data within Patent Applications" (see Research Disclosure Database Number 605005, 2014, August 1, 2014, or http: / / www.researchdisclosure.com / searching-disclosures). During peak-picking, as described in Research Disclosure Database Number 605005, the parameter "minimum height" can be adjusted between 1% and 4%. Depending on the chemical structure and / or the concentration of the compound being measured, setting the parameter "minimum height" <1% may be reasonable.

Therefore, unless otherwise specified, additional terms such as "hydrochloride," "trifluoroacetate," "sodium salt," or "x HCl," "x CF3COOH," "x Na" are used in names and structural formulas. + In the case of such salts, the term should not be understood in a stoichiometric sense, but rather should be interpreted only in a descriptive sense regarding the salt-forming components present.

[0802] This applies if the synthetic intermediate or working example or its salt is obtained by the described preparation and / or purification methods in the form of a solvate, such as a hydrate, with an unknown stoichiometric composition (if they are of a defined type).

[0831] When the compounds of the present invention are purified by preparative HPLC using the above-described method in which the eluent contains an additive (such as trifluoroacetic acid, formic acid, or ammonia), if the compounds of the present invention contain sufficient basic or acidic functionality, the compounds of the present invention can be obtained in the form of salts, such as trifluoroacetate salts, formate salts, or ammonium salts. Such salts can be converted into the corresponding free bases or acids by those skilled in the art using a variety of known methods.

[0832] In the synthetic intermediates and working examples of the invention described below, any compound described as a salt of a corresponding base or acid is generally a salt of unknown exact stoichiometric composition obtained by its respective preparation and / or purification methods. Therefore, unless otherwise specified, the additional terms in the name and structural formula, such as “hydrochloride,” “trifluoroacetate,” “sodium salt,” or “x HCl,” “xCF3COOH,” “x Na+,” should not be interpreted stoichiometrically in the case of such salts, but rather as descriptive of the salt-forming components present therein.

[0833] This applies if the synthetic intermediate or working example or its salt is obtained by the described preparation and / or purification methods in the form of a solvate, such as a hydrate, with an unknown stoichiometric composition (if they are of a defined type).
