AI Technical Summary
Existing arginine vasopressin V2 receptor antagonists, such as tolvaptan, produce a large number of metabolites in the body, leading to hepatotoxicity and limiting their application. Therefore, it is necessary to develop new V2 receptor antagonists with low side effects and high efficacy.
A class of benzozazepine cyclic derivatives were designed as V2 receptor antagonists. Their efficacy was optimized through specific structural modifications, reducing hepatotoxicity, improving selectivity and efficacy, avoiding the hook effect, and prolonging the half-life.
This resulted in a V2 receptor antagonist with low hepatotoxicity, long half-life, and high selectivity, which reduced bile excretion and GSH capture, avoided the production of DM4103-like metabolites, and improved therapeutic efficacy.

[0005] Application No. CN2025103628237, Application Date: March 25, 2025. TECHNICAL FIELD
[0006] The present invention relates to a compound represented by formula (I) and a pharmaceutically acceptable salt thereof, and in particular, the present invention relates to a class of benzazepine derivatives as V2 receptor antagonists. BACKGROUND
[0007] Hormones play an important role in the regulation of homeostasis in the human body, among which arginine vasopressin (AVP) is closely related to the regulation of water and sodium metabolism in the human body. Metabolic disorders of arginine vasopressin (AVP) can cause hyponatremia, syndrome of inappropriate antidiuretic hormone secretion, congestive heart failure, cirrhosis, kidney disease, hypertension, and edema, etc. Arginine vasopressin (AVP) receptor antagonists can inhibit the binding of AVP to the receptor, thereby playing a therapeutic role in the above diseases. Arginine vasopressin V2 receptor antagonists represented by tolvaptan can increase free water excretion while not affecting electrolyte metabolism, thereby becoming an ideal drug for treating the above diseases. However, the marketed AVP V2 receptor antagonists, such as tolvaptan, are metabolized by liver metabolic enzymes, which produce a large amount of metabolites in the body and cause severe drug-induced liver toxicity. FDA has given a black box warning on the drug product label, limiting its application. Therefore, it is very important to develop new V2 receptor antagonists with high efficiency and low side effects. SUMMARY

In one salt form, the compound is rendered sufficiently basic or acidic by the presence of the counterion thereby rendering the compound a sufficiently acidic or basic salt form to form a salt with the counterion.
[0094] Pharmaceutically acceptable salts of the present application can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts are prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent or in a mixture of the two.
[0095] The compounds of the present application can exist in particular geometric or stereoisomeric forms. The present application contemplates all such compounds, including cis- and trans-forms, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)- isomers, (L)-isomers, as well as the racemic mixtures and other mixtures thereof, such as, for example, partial racemate and scalemic mixtures, and all such isomeric forms are intended to be within the scope of the present application. Additional asymmetric carbon atoms can be present in a substituent group. All such isomers, as well as mixtures thereof, are included in the present application.
[0096] Unless otherwise stated, a solid line wedge bond and a dashed line wedge bond indicate the absolute configuration about a stereocenter.
[0097] Unless otherwise stated, the term "tautomer" or "tautomer forms" refers to different functional group isomers that are in dynamic equilibrium at room temperature and rapidly interconvert. If tautomers are possible (e.g., in solution), a chemical equilibrium of the tautomers can be reached. For example, proton tautomers (also known as prototropic tautomers) include interconversions by proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers include interconversions by reorganization of some of the bonding electrons. A specific example of keto-enol tautomerization is the interconversion between the two tautomers of pentane-2,4-dione and 4-hydroxypent-3-en-2-one.
[0098] The compounds of the present application can contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds can be radiolabeled with radioactive isotopes, such as for example tritium ( 3 H), iodine-125 ( 125 I) or C-14 ( 14 C). For example, deuterium can be substituted for hydrogen to form deuterated drugs, which have advantages over non-deuterated drugs, such as reduced toxicity, increased stability, increased efficacy, increased biological half-life, etc. All isotopic variations of the compounds of the present application, whether radioactive or not, are included within the scope of the present application.
[0099] "Optional" or "optionally" means that the event or condition described below may occur but is not required to occur, and the description includes both the scenario in which said event or condition occurs and the scenario in which said event or condition does not occur.
[0100] The term "substituted" means that any one or more hydrogen atoms on a particular atom are replaced by a substituent, which may include deuterium and hydrogen variants, provided that the valence state of the particular atom is normal and the substituted compound is stable. The term "optionally substituted" means that it may or may not be substituted, unless otherwise specified, and the type and number of substituents may be arbitrary on the basis of chemical feasibility.
[0101] When any variable (e.g., R) appears more than once in the composition or structure of a compound, its definition is independent in each case. Therefore, for example, if a group is substituted by one, two, or three Rs, the group can optionally be substituted by up to three Rs, and each case has an independent option for R. Furthermore, combinations of substituents and / or their variants are only permitted if such combinations produce a stable compound. For example, Can be selected wait.
[0102] When one of the variables is selected as a single bond, it means that the two groups it connects to are directly connected, for example... When L2 represents a single bond, it means that the structure is actually A hyphen ("-") not between two letters or symbols indicates the connection site of a substituent. For example, C 1-6 Alkyl carbonyl group - refers to a carbonyl group connected to the rest of the molecule via a carbonyl group. 1-6 Alkyl groups. However, when the linking site of the substituent is obvious to those skilled in the art, such as halogen substituents, the "-" may be omitted.
[0103] Unless otherwise specified, when the valence bonds of groups in the structural unit are marked with dashed lines... In this context, dashed lines represent the connection points between the structural unit and other parts of the molecule. For example, in the "structural unit" section... In the text, the dashed line represents... The connection points between a group and other parts of a molecule. For example, in a "structural unit". In the text, the dashed line represents... and The fusion junctions thus form
[0104] When a substituent is recited without indicating that it is attached to a substituted group by a particular atom, then the substituent can be attached by any atom in the substituent that results in a stable compound, for example, a pyridyl group as a substituent can be attached at any of the carbon atoms of the pyridyl ring to the group being substituted.
[0105] When a linking group is recited without indicating its direction of attachment, its direction of attachment is arbitrary, for example, wherein the linking group L is wherein the linking group L is wherein the phenyl group and the cyclopentyl group are attached in the same direction as the reading order from left to right wherein the phenyl group and the cyclopentyl group are attached in the opposite direction as the reading order from left to right Combinations of the linking groups, substituents, and / or variations thereof are only permitted if such combinations result in stable compounds.

The number of atoms in a ring is often defined as the ring size, for example, a "4-6 membered ring" refers to a "ring" that is arranged around 4-6 atoms. When a ring is substituted, the atoms included in the substituent are not included in the number of atoms in the ring. Unless otherwise specified, benzene is a 6-membered ring, naphthalene is a 10-membered ring, and thiophene is a 5-membered ring.

[0128] It will be understood by those skilled in the art that some of the compounds of Formula (I) can comprise one or more chiral centers and, therefore, exist as two or more stereoisomers. Accordingly, the compounds of the present application can exist as individual stereoisomers (e.g., enantiomers, diastereomers) and mixtures of stereoisomers, for example, racemates, in any ratio, and, where appropriate, as tautomers and geometric isomers.
[0129] The term "stereoisomers" as used herein refers to compounds which have identical chemical constitution, but differ in the arrangement of atoms or groups in space.
[0130] The term "enantiomers" as used herein refers to two stereoisomers of a compound which are non-superimposable mirror images of one another.
[0131] The term "diastereomer" as used herein refers to a stereoisomer that has two or more chiral centers and whose molecules are not a mirror image of each other. Diastereomers have different physical properties, such as melting point, boiling point, spectral properties, or biological activity. Mixtures of diastereomers can be separated by high resolution analytical methods, such as electrophoresis and chromatography, e.g., HPLC.
[0132] Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and 1 or (+) and (-) are employed to designate the sign of the rotation of plane-polarized light by the compound, with (-) or 1 meaning that the compound is levorotatory. A compound, which is dextrorotatory, has the (+) or d designation. For a given chemical structure, these stereoisomers are identical except that they are mirror images of one another. A specific stereoisomer can also be referred to as an enantiomer when there are two stereoisomers and a mixture of such isomers is often referred to as an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture or racemate, which can occur where there has been no stereoselection or stereospecificity in a chemical process or method. The terms "racemic mixture" and "racemate" mean an equimolar mixture of two enantiomeric forms lacking any optical activity.
[0133] A racemic mixture can be used as is or resolved into its individual isomers. A stereochemically pure compound or a mixture enriched in one or more isomers can be obtained by resolution of the racemic mixture. Methods for separating isomers are well known, including physical methods such as chromatography using a chiral adsorbent. Individual isomers can be prepared in chiral form from chiral precursors. Alternatively, individual isomers can be obtained chemically from mixtures by forming diastereomeric salts with a chiral acid (such as the individual enantiomers of 10-camphorsulfonic acid, camphoric acid, a-bromocamphoric acid, tartaric acid, diacetyltartaric acid, malic acid, pyrrolidine-5-carboxylic acid, and the like), fractional crystallization of the salts, and the like, and the isolated salt of the desired isomer is liberated by treatment with an alkali or an acid, optionally repeating the procedure to obtain a second isomer, to yield one or both isomers substantially free of the other, i.e., optical purity of, for example, at least 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 99.5% by weight of the desired stereoisomer. Alternatively, the racemate can be covalently bonded to a chiral compound (auxiliary) to give a diastereomeric mixture, as is well known in the art.
[0134] As used herein, the terms "tautomer" or "tautomer form" refer to structural isomers of different energies that can be interconverted via low-energy barriers. For example, proton tautomers (also known as proton transfer tautomers) include interconversions via proton migration, such as keto-enol and imine-enamine isomerization. Valence tautomers include interconversions via the recombination of some bonding electrons.
[0135] The compounds of the present invention can be prepared by a variety of synthetic methods known to those skilled in the art, including the specific embodiments listed below, embodiments formed by combining them with other chemical synthetic methods, and equivalent substitutions known to those skilled in the art. Preferred embodiments include, but are not limited to, the embodiments of the present invention.

On the experimental day, the cells were trypsinized, washed twice with the stimulation buffer in the cAMP-GS HIRANGE kit, resuspended and counted, and then prepared into 1.6 x 105cells / mL for use. 6Cells were diluted to 1.5 x 105cells / ml, and IBMX was added to a final concentration of 0.5 mM. 5 μL of cell suspension was transferred to each well of a 384-well plate, and 2.5 μL of the test compound at different concentrations (10 μM with 3-fold dilution, 10 concentration points) or DMSO (minimum value Min, maximum value Max control) was added to the corresponding wells. After incubation at room temperature for 30 minutes, 2.5 μL of vasopressin AVP solution was added to the test compound wells and the maximum value wells to a final concentration of 2.25 nM, and 2.5 μL of stimulation buffer was added to the minimum value wells, and incubation was performed at 25°C for 60 minutes. At the same time, cAMP standard samples were prepared (3-fold dilution from 5.6 μM, 10 concentration points), and 10 μL of cAMP standard was transferred to the corresponding wells of a 384-well plate. The cAMP-d2 fluorescence and anti-cAMP antibody probes provided in the cAMP-GS HIRANGE kit were diluted 5-fold with lysis buffer in the kit, and 5 μL of each was sequentially added to each well of the 384-well plate. After mixing and simple centrifugation, incubation was performed at 25°C for 2 hours, and detection was performed. Sample detection was performed using the HTRF method in the Envision enzyme label instrument, and the fluorescence intensities at 615 nm and 665 nm were detected. Two replicate wells were prepared for each test sample, and 16 replicate wells were prepared for Min and Max.
[0421] (4) Data processing
[0422] The fluorescence intensity ratio FI of each well sample at 665 nm and 615 nm was calculated. 665 / 615 The standard curve was obtained by fitting the log of the standard sample concentration as X and FI 665 / 615 X1000 as Y in the Prism 8.0 software using the “log(inhibitor) vs response – variable slope (four parameters)” model. The FI 665 / 615 X1000 of the test well was taken as Y, and the cAMP concentration corresponding to each sample was calculated according to the above standard curve in the Prism 8.0 software.
[0423] The inhibition percentage was calculated according to the following formula:
[0424] wherein, is the average calculated value of the cAMP concentration in all maximum value wells; is the average calculated value of the cAMP concentration in all minimum value wells; and Ccmpd is the calculated value of the cAMP concentration of the test compound.
[0425] The IC50values were calculated by non-linear regression in Prism 8.0 software with the model of "log(inhibitor) vs response - variable slope (four parameters)", taking % Inhibition as Y value and the logarithm of compound concentration as X. 50 where Y = Bottom + (Top - Bottom) / (1 + 10^((LogIC 50 X) * Hill Slope)).
[0426] The experimental results are shown in Table 1, in which the IC 50 Classification is as follows: "+++++" represents IC 50 < 0.5 nM, "++++" represents 0.5 nM < IC 50 < 5 nM, "+++" represents 5 nM < IC 50 < 50 nM, "++" represents 50 nM < IC 50 < 500 nM, "+" represents 500 nM < IC 50 < 5 μM.
