[0002] (Technical field) The present invention relates to nitrogen-containing heterocyclic compounds and their uses, and more specifically discloses compounds represented by formula (II), their stereoisomers, and pharmaceutically acceptable salts thereof. [Background technology]
[0003] Hypertension is a clinical syndrome primarily characterized by elevated arterial blood pressure in the systemic circulation (systolic and / or diastolic blood pressure) (systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg), accompanied by functional or organic damage to organs such as the heart, brain, and kidneys. Medications commonly used to treat hypertension include five categories: calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), diuretics, and beta-blockers, as well as fixed-ratio combination preparations of these drugs. Furthermore, some individuals with hypertension may also use alpha-blockers or other types of antihypertensive drugs (e.g., renin inhibitors, central nervous system agonists, etc.).
[0004] For adult hypertensive patients requiring drug therapy, one of three antihypertensive drugs (diuretics, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers, or calcium channel blockers) is recommended as the first-line treatment. For hypertensive patients whose blood pressure cannot be controlled to the target level with a single drug, the combination of antihypertensive drugs is the basic method of antihypertensive treatment. Most hypertensive patients need to use two or more antihypertensive drugs to achieve the target blood pressure level. If a patient's blood pressure remains above 140 mmHg despite taking at least three different types of antihypertensive drugs (one of which is a diuretic), it is called refractory hypertension. In patients with refractory hypertension, a fourth drug such as a beta-blocker, aldosterone receptor blocker, triamterene, clonidine, or alpha-blocker is needed in addition to the three drugs.
[0005] Since 2007, no new antihypertensive drugs have been approved for sale, and many patients with refractory hypertension still do not receive appropriate treatment. Both refractory hypertension and hyperaldosteronism are characterized by sodium and water retention. Clinical trials have shown that baxdrostat dose-dependently lowers blood pressure and aldosterone secretion levels, indicating that aldosterone is a key factor in drug resistance in patients with refractory hypertension. The main pharmacological targets for treating refractory hypertension by lowering aldosterone levels include blockade of mineralocorticoid receptors and inhibition of aldosterone synthase.
[0006] Aldosterone is encoded by the CYP11B2 gene, which simultaneously possesses the functions of 11-β-hydroxylase, 18-hydroxylase, and 18-dehydrogenase. Its role is primarily in the final stage of aldosterone synthesis, producing aldosterone using 11-deoxycorticosterone (11-DOC) as a substrate. CYP11B1 and CYP11B2 have 93% similar amino acid sequences, and inhibiting CYP11B1 activity may cause adrenal insufficiency. Highly selective inhibition of aldosterone synthase is highly necessary but difficult to achieve. Baxdrostat, a small molecule, highly selective aldosterone synthase inhibitor, was confirmed in a phase 2 trial to have four main advantages: a significant blood pressure reduction effect, no effect on cortisol levels, a low incidence of increased serum potassium levels, and no accumulation of steroid precursors. Baxdrostat, at a dose of 2 mg, is effective in lowering systolic and diastolic blood pressure in the doctor's office for patients with refractory hypertension, and has good safety and tolerability. [Overview of the project] [Problems that the invention aims to solve]
[0007] In summary, the development of selective aldosterone synthase inhibitors represents a new drug with great potential for treating diseases associated with elevated aldosterone levels (including refractory hypertension and primary aldosteronism), providing more treatment options in clinical practice.

[0075] (Definitions and explanations)
[0076] Unless otherwise stated, the following terms and collocations used herein are intended to have the following meanings. Unless specifically defined, any particular term or collocation should not be interpreted as ambiguous or unclear, but rather should be understood as having its ordinary definition. Where a trade name appears herein, it refers to the corresponding product or its active ingredient.
[0077] As used herein, the term “pharmaceutically acceptable” applies to compounds, materials, compositions and / or dosage forms that are within the bounds of reliable medical judgment, suitable for use in contact with human and animal tissues, with little toxicity, irritation, allergic reaction or other problem or complication, and that meet a reasonable benefit / risk ratio.
[0078] The term "pharmaceutically acceptable salt" refers to a salt of the compound of the present invention, which is prepared with a compound having a specific substituent discovered in the present invention and a relatively non-toxic acid or base. If the compound of the present invention contains a relatively acidic functional group, a base addition salt can be obtained by contacting these compounds with a sufficient amount of base in a single solution or a suitable inert solvent. If the compound of the present invention contains a relatively basic functional group, an acid addition salt can be obtained by contacting these compounds with a sufficient amount of acid in a single solution or a suitable inert solvent. Since some specific compounds of the present invention contain basic and acidic functional groups, they can be converted into any base addition salt or acid addition salt.
[0079] The pharmaceutically acceptable salts of the present invention can be synthesized by conventional methods from a parent compound containing an acidic or basic moiety. Typically, such salts are produced by reacting these compounds, in the form of free acids or bases, with a stoichiometric amount of a suitable base or acid in water, an organic solvent, or a mixture thereof.
[0080] Unless otherwise specified, the term "isomer" includes geometric isomers, cis-trans isomers, stereoisomers, enantiomers, optical isomers, diastereomers, and tautomers.
[0081] The compounds of the present invention may exist in specific geometric or stereoisomeric forms. The present invention envisions all such compounds and includes cis and trans isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)-isomers, (L)-isomers, and racemic mixtures thereof, as well as other mixtures, such as mixtures containing a large amount of enantiomers or diastereomers, all of which are within the scope of the present invention. Other chiral carbon atoms may be present in substituents such as alkyl groups. All of these isomers and mixtures thereof are within the scope of the present invention.
[0082] Unless otherwise specified, the terms "enantiomer" or "optical isomer" refer to stereoisomers that are mirror images of each other.
[0083] Unless otherwise explained, the terms "cis-trans isomer" or "geometric isomer" refer to the inability of the double bond or the single bond of the ring-forming carbon atoms to rotate freely.
[0084] Unless otherwise specified, the term "diastereomer" refers to a stereoisomer in which a molecule has two or more chiral centers and the molecules are non-mirror images of each other.
[0085] Unless otherwise specified, "(+)" indicates dextrorotatory properties, "(-)" indicates levorotatory properties, and "(±)" indicates a racemic mixture.
[0086] Unless otherwise explained, wedge-shaped solid line connections [ka] and wedge-shaped dotted line connections [ka] The absolute arrangement of the center of one solid is connected by a solid line. [ka] and line-dotted line combinations [ka] The relative arrangement of the center of the solid is shown by the wavy line. [ka] wedge-shaped solid line connection [ka] or wedge-shaped dotted line connection [ka] or a wavy line [ka] Linear solid line combination [ka] or a combination of straight and dotted lines [ka] It represents.
[0087] Unless otherwise specified, the terms “rich in one isomer,” “rich in isomers,” “rich in one enantiomer,” or “rich in enantiomers” mean that the content of one isomer or enantiomer is less than 100%, and that the content of this isomer or enantiomer is 60% or more, or 70% or more, or 80% or more, or 90% or more, or 95% or more, or 96% or more, or 97% or more, or 98% or more, or 99% or more, or 99.5% or more, or 99.6% or more, or 99.7% or more, or 99.8% or more, or 99.9% or more.
[0088] Unless otherwise specified, the terms "isomer excess" or "enantiomer excess" refer to the difference between the relative percentages of two isomers or two enantiomers. For example, if one isomer or enantiomer is present at 90% and the other isomer or enantiomer is present at 10%, the isomer or enantiomer excess (ee value) is 80%.
[0089] The optically active (R)- and (S)-isomers, as well as the D and L isomers, can be produced by chiral synthesis, chiral reagents, or other conventional techniques. To obtain one enantiomer of a compound of the present invention, it can be produced by asymmetric synthesis or derivatization with a chiral auxiliary agent, where the resulting diastereomer mixture can be separated and the auxiliary group cleaved to obtain the pure enantiomer of the desired type. Alternatively, if the molecule contains a basic functional group (e.g., amino) or an acidic functional group (e.g., carboxy), a salt of the diastereomer can be formed with a suitable optically active acid or base, and then the diastereomer can be separated by conventional methods known in the art and recovered to obtain the pure enantiomer. Furthermore, the separation of enantiomers and diastereomers is usually performed using chromatography with a chiral stationary phase, and, if necessary, combined with chemical derivatization methods (e.g., producing a carbamate from an amine).
[0090] The compounds of the present invention may contain unnatural proportions of atomic isotopes in one or more atoms constituting the compound. For example, tritium ( 3 H), Iodine-125( 125 I), C-14( 14 Compounds labeled with radioactive isotopes such as C) may also be used.
[0091] Furthermore, for example, deuterated drugs can be formed by substituting hydrogen with deuterium. The bond formed between deuterium and carbon is stronger than the bond formed between ordinary hydrogen and carbon. Compared to non-deuterated drugs, deuterated drugs have advantages such as reduced toxic side effects, increased drug stability, enhanced therapeutic effects, and extended biological half-life. The conversion of the isotopic composition of the compounds of the present invention is included within the scope of the present invention, whether or not they are radioactive.
[0092] The terms "optional" and "at willing discretion" may appear in the events or situations described below, but are not necessarily so, and such descriptions include cases where the aforementioned events or situations occur, as well as cases where the aforementioned matters or situations do not occur.
[0093] The term "substituted" refers to the substitution of any one or more hydrogen atoms in a particular atom with a substituent. The substituent may include deuterium and hydrogen variants, provided that the specific valence state is normal and the substituted compound is stable. When the substituent is oxo (i.e., =O), it means that two hydrogen atoms have been substituted.
[0094] The term "optionally substituted" means that substitution is optional, and unless otherwise defined, the type and number of substituents are arbitrary as long as they can be chemically realized.
[0095] If any of the variables (e.g., R) appear once or more in the composition or structure of a compound, their definitions are independent in each case. Therefore, for example, if one group is substituted with 0 to 2 Rs, the group can be substituted with any two or fewer Rs, and in each case, Rs have independent choices. Furthermore, combinations of substituents and / or their variants are only permitted if such combinations result in a stable compound.
[0096] When the number of linking groups is 0, for example, -(CRR)0-, it means that the linking group is a single bond.
[0097] A value of 0 for the number of substituents indicates that the substituent is absent. For example, -A-(R)0 represents a structure that is actually -A.
[0098] If a substituent is empty, it means that substituent does not exist. For example, if X in AX is empty, it means that the structure is actually A.
[0099] When one of the variables is selected from a single bond, the two groups connected by it are directly linked. For example, if L in ALZ represents a single bond, then this structure is indeed AZ.
[0100] If the connection direction of the listed linking groups is not specified, the connection direction is arbitrary, for example, [ka] The linking group L in this case is -MW-, and in this case -MW- links ring A and ring B in the same direction as the reading order from left to right. [ka] It is possible to construct this, and also connect ring A and ring B in the reverse direction of the reading order from left to right. [ka] It is also possible to construct such a compound. The combination of the linking group, substituent and / or its variants is only permissible if such a combination results in a stable compound.
[0101] Unless otherwise specified, if a group has one or more bondable sites, any one or more of these sites can be bonded to other groups by chemical bonds. If the bonding mode of the chemical bond is delocalized and hydrogen atoms are present at the bondable sites, when a chemical bond is formed, the number of hydrogen atoms at the sites decreases to a group with a corresponding valency in proportion to the number of chemical bonds formed. The chemical bond formed by the bonding of the sites to other groups is a linear solid bond. [ka] , dashed line connection [ka] or wavy line [ka] It can be represented as follows. For example, the linear solid bond of -OCH3 represents a bond to another group via an oxygen atom within that group. [ka] The dashed line in the diagram indicates that the nitrogen atom within that group is bonded to another group via both ends. [ka] The wavy line indicates that the phenyl molecule is bonded to another group via the carbon atoms at positions 1 and 2.
[0102] [ka] This indicates that any bondable site of the piperidinyl can bond to another group via one chemical bond, at least [ka] This includes the four bonding methods, and even when the H atom is depicted as -N-, [ka] for [ka] The group contains a bonding method, however, when bonded to one chemical bond, the number of H atoms at that site decreases by one, resulting in the corresponding monovalent piperidinyl.
[0103] Unless otherwise specified, when rings A and B are fused, they share one bond, and the atom on that bond may be a carbon atom or a nitrogen atom, for example, [ka] In the condensed bond between A and B, the atom is either C or N. [ka] This includes, but is not limited to, these.
[0104] Unless otherwise explained, the number of atoms in a ring is generally defined as the number of ring members. For example, a "5- to 7-membered ring" refers to a "ring" in which 5 to 7 atoms are arranged around it.
[0105] Unless otherwise defined, the terms “halogen element” or “halogen” refer to a fluorine, chlorine, bromine, or iodine atom, either by itself or as part of another substituent.

[0124] Calculation example 1 [ka]
[0125] The molecular docking process was performed using Maestro (Schrodinger version 2022-1) Glide SP[1] and default settings. The co-crystal structure of CYP11B2 (PDB ID: 4ZGX) was selected as the docking template. To produce the protein, hydrogen atoms were added using the Maestro[2] Protein Production Wizard module and the OPLS4 force field was used. For ligand production, the LigPrep module was used to generate the three-dimensional structure of the molecule, energy minimization[3] was performed, and the ConfGen module was used to explore small molecule conformations[4]. The Receptor Grid Generation module of Glide was used to generate the grid file required for docking, with the ligand of the crystal structure as the center of the docking box. The interaction types between the protein receptor and ligand were analyzed, and molecules with high potential were selected, synthesized, and tested based on the calculated docking score and binding mode. The binding modes of compounds 1A, 2A, and 3A are shown in Figures 1, 2, and 3.

[0436] Experimental Example 6: In vitro metabolic stability study of liver microsomes
[0437] Experimental objective: To evaluate the metabolic stability of the test compound in human liver microsomes.
[0438] Experimental materials: Reduced nicotinamide adenine dinucleotide phosphate (NADPH), purchased from Corning or Xenotech and stored in a -80°C freezer; Supplier: Chem-impex international; Control compounds: testosterone, diclofenac, propafenone.
[0439] Experimental procedure:
[0440] 1. Preparation of the working solution Stock solution: 10 mM DMSO solution. Preparation of working solution concentration: The stock solution was diluted to 100 μM with 100% acetonitrile (organic phase content: 99% acetonitrile, 1% DMSO).
[0441] 2. Experimental Procedure Two 96-well culture plates, named T60 culture plates and NCF60 culture plates respectively, were prepared and preheated for 10 minutes.
[0442] Liver microsomes were diluted with 100 mM potassium phosphate buffer to a protein concentration of 0.56 mg / mL.
[0443] 445 μL of microsomal working solution (hepatic microsome protein concentration: 0.56 mg / mL) was transferred to preheated culture plates T60 and NCF60, respectively, and pre-cultured in a 37°C water bath for approximately 10 minutes.
[0444] After pre-culture, 5 μL of the test sample or control compound working solution was added to the T60 culture plate and the NCF60 culture plate, respectively, and mixed. 50 μL of potassium phosphate buffer was added to each well of the NCF60 culture plate and mixed uniformly to initiate the reaction.
[0445] 180 μL of stop solution (acetonitrile solution containing 200 ng / mL tolbutamide and 200 ng / mL labetalol) and 6 μL of NADPH regeneration system working solution were added to the T0 stop plate, and 54 μL of sample was transferred from the T60 culture plate to the T0 stop plate (T0 sample was generated). 44 μL of NADPH regeneration system working solution was added to each well of the T60 culture plate to initiate the reaction. Only 54 μL of microsome working solution, 6 μL of NADPH regeneration system working solution, and 180 μL of stop solution were added to a blank plate. Consequently, in the test compound or control compound samples, the final reaction concentrations of the compound, testosterone, diclofenac, and propafenone were 1 μM, the liver microsome concentration was 0.5 mg / mL, and the final concentrations of DMSO and acetonitrile in the reaction system were 0.01% (v / v) and 0.99% (v / v), respectively.
[0446] After culturing for the appropriate time (5, 15, 30, 45, 60 minutes), 180 μL of stop solution was added to each sample well of the stop plate, and then 60 μL of sample was removed from the T60 culture plate and placed in the stop plate to stop the reaction.
[0447] After uniformly shaking all sample plates, they were centrifuged at 4°C for 20 minutes (rotation speed: 4000 rpm). 80 μL of supernatant was taken from each well, diluted in 240 μL of pure water, and mixed uniformly for 10 minutes. LC-MS / MS analysis was performed. The experimental results are shown in Table 8.
[0448] [Table 8]
[0449] Experimental conclusion: The compounds of the present invention exhibited low clearance rates in human liver microsomes and good metabolic stability.
[0450] Experimental Example 7: Plasma Protein Binding Rate Test of Compounds
[0451] Experimental objective: To evaluate the protein binding rate of the compound of the present invention in the plasma of SD rats, cynomolgus monkeys, and humans using equilibrium dialysis.
[0452] Test protocol: 796 μL of blank plasma (purchased from Bioreclamation IVT) was collected from humans, SD rats, and cynomolgus monkeys, and either a test compound working solution or a warfarin working solution was added to achieve a final concentration of 2 μM of the test compound and warfarin in the plasma samples.
[0453] The samples were thoroughly mixed. The final concentration of DMSO in the organic phase was 0.5%. 50 μL of the test compound and warfarin plasma sample were transferred to a sample receiving plate, and the corresponding volume of blank plasma or buffer was added to bring the final volume of each sample well to 100 μL, with a plasma:dialysis buffer volume ratio of 1:1. Then, stop solution was added to these samples, and these samples were designated as T0 samples for recovery and stability testing.
[0454] The test compound and warfarin plasma sample were added to the administration end of each dialysis well, and blank dialysis buffer was added to the corresponding receptor end of each dialysis well. Next, the dialysis plate was sealed with a gas-permeable membrane and placed in a humidified 5% CO2 incubator, where it was incubated at 37°C and 100 rpm for 4 hours with shaking.
[0455] After dialysis was completed, 50 μL of dialysis buffer sample and post-dialysis plasma sample were pipetteed into a new sample receiving plate. Each sample well had a final volume of 100 μL, and the corresponding volume of blank plasma or buffer was added to the sample so that the plasma:dialysis buffer volume ratio was 1:1.
[0456] Data analysis:
[0457] After protein precipitation treatment of all samples, LC / MS / MS analysis was performed, and the ionization rate and plasma protein binding rate of the compounds were calculated using the following formulas: Ionization rate (%) = 100 × Fc / Tc, Plasma protein binding rate of the compound (%) = 100% - Ionization rate of the compound (%). Here, Fc is the concentration of the compound at the buffer end of the dialysis plate, Tc is the concentration of the compound at the plasma end of the dialysis plate, and T0 is the concentration of the compound in the plasma sample at zero time. The experimental results are shown in Table 9.
[0458] [Table 9]
[0459] Experimental conclusion: The compound of the present invention exhibits moderate binding affinity to different types of plasma proteins, an appropriate proportion of free drug in plasma, and good drug-forming ability.
[0460] Experiment Example 8: Human liver microsomal CYP inhibition experiment
[0461] Experimental Objective: To evaluate the inhibitory activity of a test substance against human liver microsomal cytochrome P450 isozymes (CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4) using a 5-in-1 probe substrate for CYP isozymes.
[0462] Mixed human liver microsomes (HLMs) were purchased from Corning Inc. (Steuben, New York, USA) and stored at -70°C or below until use.
[0463] Diluted test sample working solutions were added to a culture system containing human liver microsomes, probe substrates, and cardiovascular cofactors. A control solution containing only the solvent and no test sample was used as the enzyme activity control (100%). The concentrations of metabolites produced by the probe substrate in the samples were measured by liquid chromatography-tandem mass spectrometry (LC-MS / MS). Nonlinear regression analysis of the mean activity rate and concentration of the test samples was performed using SigmaPlot (V.11). 50 The values were calculated using inverse logarithmic equations with three or four parameters. The experimental results are shown in Table 10.
[0464] [Table 10]
[0465] Experimental conclusion: The compounds of the present invention do not have inhibitory effects on the CYP enzymes CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4, and the risk of drug interactions is extremely low.
