[0006] The present invention relates to pyrazine thio - biphenyl compounds and their applications, and particularly to compounds of formula (II) or pharmaceutically acceptable salts thereof. Background Art

[0007] The phosphorylation of tyrosine kinases and the de - phosphorylation of tyrosine phosphatases are common signal transduction mechanisms in organisms, which jointly regulate the tyrosine phosphorylation level of intracellular proteins. Shp2 (SH2 domain - containing protein - tyrosine phosphatase - 2) is a non - transmembrane protein tyrosine phosphatase that plays a de - phosphorylation role and is an important member of the protein tyrosine phosphatase (PTP) family. Its molecule is encoded by the PTPN11 gene. It can not only positively regulate downstream signal transduction pathways through the catalytic activity of phosphatase, but also play a positive regulatory role as a phosphatase - independent adapter protein, and can also play a negative regulatory role under specific conditions, thus widely participating in the regulation of biological functions such as cell differentiation and migration and related signal transduction processes. PTPN11 mutation is considered a high - risk factor for juvenile myelomonocytic leukemia (JMML). At the same time, because of the abnormal activation and mutation of Shp2 in different types of leukemia, it is considered an oncogene of leukemia; in prostate cancer, breast cancer, pancreatic cancer, gastric cancer and glioma, Shp2 has also been reported to be in an over - activated state; in lung cancer, Shp2 promotes tumorigenesis and development as an oncogene by regulating multiple mechanisms. However, in the process of liver cancer occurrence, Shp2 plays the role of a tumor suppressor gene under the influence of a specific environment. In short, as an important nodal molecule, Shp2 plays an important regulatory role in the process of tumorigenesis and development and is a potential therapeutic target. Summary of the Invention

[0101] Definitions and explanations

[0102] Unless otherwise specified, the following terms and phrases used herein are intended to have the following meanings. A specific term or phrase should not be considered indeterminate or unclear without a special definition, but should be understood in its ordinary meaning. When a trade name appears in this text, it is intended to refer to its corresponding product or its active ingredient.

[0103] As used herein, the term "pharmaceutically acceptable" pertains to those compounds, materials, compositions, and / or dosage forms that, within the scope of sound medical judgment, are suitable for use in contact with the tissues of humans and animals without excessive toxicity, irritation, allergic response, or other problems or complications, commensurate with a reasonable benefit / risk ratio.

[0104] The term "pharmaceutically acceptable salt" refers to salts of the compounds of the present invention, prepared from compounds having specific substituents found in the present invention with relatively non-toxic acids or bases. When a compound of the present invention contains a relatively acidic functional group, the base addition salt can be obtained by contacting such a compound with a sufficient amount of a base in a pure solution or a suitable inert solvent. Pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amine, or magnesium salts or similar salts. When a compound of the present invention contains a relatively basic functional group, the acid addition salt can be obtained by contacting such a compound with a sufficient amount of an acid in a pure solution or a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include inorganic acid salts, where the inorganic acids include, for example, hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, monohydrogen phosphate, dihydrogen phosphate, sulfuric acid, hydrogen sulfate, hydroiodic acid, phosphorous acid, etc.; and organic acid salts, where the organic acids include, for example, acetic acid, propionic acid, isobutyric acid, maleic acid, malonic acid, benzoic acid, succinic acid, suberic acid, fumaric acid, lactic acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-toluenesulfonic acid, citric acid, tartaric acid, and methanesulfonic acid and similar acids; also salts of amino acids (such as arginine, etc.), and salts of organic acids such as glucuronic acid. Certain specific compounds of the present invention contain both basic and acidic functional groups and can thus be converted into either base or acid addition salts.

[0105] The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compounds containing acid or base groups by conventional chemical methods. Generally, the preparation method of such salts is to react these compounds in the form of free acids or bases with a stoichiometric amount of an appropriate base or acid in water or an organic solvent or a mixture of both.

[0106] The compounds of the present invention can exist in specific geometric or stereoisomeric forms. The present invention contemplates all such compounds, including cis and trans isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)-isomers, (L)-isomers, and their racemic mixtures and other mixtures, such as enantiomer- or diastereomer-enriched mixtures, all of which mixtures are within the scope of the present invention. Additional asymmetric carbon atoms may be present in substituents such as alkyl groups. All such isomers and their mixtures are included within the scope of the present invention.

[0107] Unless otherwise specified, the term "enantiomer" or "optical isomer" refers to stereoisomers that are mirror images of each other.

[0108] Unless otherwise specified, the terms "cis-trans isomers" or "geometric isomers" are caused by the inability of double bonds or single bonds of ring carbon atoms to rotate freely.

[0109] Unless otherwise specified, the term "diastereomer" refers to stereoisomers that have two or more chiral centers and are not mirror images of each other.

[0110] Unless otherwise specified, "(+)" indicates dextrorotation, "(-)" indicates levorotation, and "(±)" indicates racemization.

[0111] Unless otherwise specified, a solid wedge bond and a dashed wedge bond are used to represent the absolute configuration of a stereocenter, and a solid straight bond and a dashed straight bond are used to represent the relative configuration of a stereocenter. A wavy line is used to represent a solid wedge bond or a dashed wedge bond or a wavy line is used to represent a solid straight bond and a dashed straight bond

[0112] Unless otherwise specified, the term "tautomer" or "tautomeric form" refers to different functional group isomers that are in dynamic equilibrium at room temperature and can rapidly interconvert. If tautomers are possible (e.g., in solution), a chemical equilibrium of tautomers can be achieved. For example, proton tautomers (also known as prototropic tautomers) include interconversions that occur through proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers include interconversions that occur through the reorganization of some 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.

[0113] Unless otherwise specified, an atom with "*" or "#" is a chiral atom or chiral center and exists in the form of a single (R) or (S) enantiomer or an enantiomer-rich form; for example, represents

[0114] Unless otherwise specified, the terms "enriched in one isomer", "isomer-enriched", "enriched in one enantiomer", or "enantiomer-enriched" mean that the content of one isomer or enantiomer is less than 100%, and the content of this isomer or enantiomer is greater than or equal to 60%, or greater than or equal to 70%, or greater than or equal to 80%, or greater than or equal to 90%, or greater than or equal to 95%, or greater than or equal to 96%, or greater than or equal to 97%, or greater than or equal to 98%, or greater than or equal to 99%, or greater than or equal to 99.5%, or greater than or equal to 99.6%, or greater than or equal to 99.7%, or greater than or equal to 99.8%, or greater than or equal to 99.9%.

[0115] 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 the content of one isomer or enantiomer is 90% and the content of the other isomer or enantiomer is 10%, then the isomer or enantiomer excess (ee value) is 80%.

[0116] Optically active (R)- and (S)-isomers and D and L isomers can be prepared by chiral synthesis or chiral reagents or other conventional techniques. If one enantiomer of a compound of the present invention is desired, it can be prepared by asymmetric synthesis or derivatization with a chiral auxiliary, where the resulting diastereomeric mixture is separated and the auxiliary group is cleaved to provide the pure desired enantiomer. Alternatively, when the molecule contains a basic functional group (such as an amino group) or an acidic functional group (such as a carboxyl group), it forms a diastereomeric salt with an appropriate optically active acid or base, and then the diastereomers are resolved by conventional methods known in the art, and then the pure enantiomer is recovered. In addition, the separation of enantiomers and diastereomers is usually accomplished by using chromatography that employs a chiral stationary phase and optionally in combination with chemical derivatization (such as forming a carbamate from an amine).

[0117] The compounds of the present invention may contain non-natural proportions of atomic isotopes on one or more atoms constituting the compound. For example, the compound can be labeled with a radioactive isotope, such as tritium ( 3 H), iodine-125 ( 125 I) or C-14 ( 14 C). Also, for example, deuterium can be used to replace hydrogen to form deuterated drugs. The bond formed by deuterium and carbon is stronger than the bond formed by ordinary hydrogen and carbon. Compared with the non-deuterated drug, the deuterated drug has advantages such as reducing toxic and side effects, increasing drug stability, enhancing efficacy, and prolonging the biological half-life of the drug. All isotopic compositions of the compounds of the present invention, whether radioactive or not, are included within the scope of the present invention.

[0118] The term "optional" or "optionally" means that the subsequently described event or condition may but does not have to occur, and this description includes the case where the described event or condition occurs and the case where the described event or condition does not occur.

[0119] 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 variants of hydrogen, provided that the valence state of the particular atom is normal and the resulting compound is stable. When the substituent is oxygen (i.e., =O), it means that two hydrogen atoms are replaced. Oxygen substitution does not occur on aromatic groups.

[0120] The term "optionally substituted" means that it may or may not be substituted, and unless otherwise specified, the type and number of substituents can be arbitrary based on what is chemically achievable.

[0121] When any variable (e.g., R) appears more than once in the composition or structure of a compound, its definition in each case is independent. Thus, for example, if a group is substituted with 0 - 2 R's, the group may optionally be substituted with up to two R's, and each R in each case has independent options. In addition, combinations of substituents and / or their variants are only permitted if such combinations result in a stable compound.

[0122] When one of the variables is selected from a single bond, it means that the two groups it connects are directly linked. For example, in A - L - Z, when L represents a single bond, it means the structure is actually A - Z.

[0123] When a substituent is vacant, it means that the substituent is absent. For example, in A - X, when X is vacant, it means the structure is actually A. When it is not specified which atom of the listed substituent is bonded to the group being substituted, such a substituent can be bonded through any of its atoms. For example, a pyridyl group as a substituent can be connected to the group being substituted through any carbon atom on the pyridine ring.

[0124] When the listed linking group does not specify its linking direction, the linking direction is arbitrary. For example, in which the linking group L is -M - W -, at this time -M - W - can connect ring A and ring B in the same direction as the reading order from left to right to form or can connect ring A and ring B in the opposite direction to the reading order from left to right to form Combinations of the described linking groups, substituents and / or their variants are only permitted if such combinations result in a stable compound.

[0125] Unless otherwise specified, when a group has one or more connectable sites, any one or more of these sites of the group can be connected to other groups by chemical bonds. When the connection mode of the chemical bond is non-specific and there are H atoms at the connectable sites, then when connecting the chemical bonds, the number of H atoms at this site will correspondingly decrease with the number of connected chemical bonds to become a group with the corresponding valence. The chemical bond connecting the site to other groups can be represented by a straight solid line bond a straight dashed line bond or a wavy line For example, the straight solid line bond in -OCH 3 represents the connection to other groups through the oxygen atom in this group; the straight dashed line bond in represents the connection to other groups through both ends of the nitrogen atom in this group; the wavy line in represents the connection to other groups through the 1- and 2-carbon atoms in this phenyl group;

[0126]

[0127] Unless otherwise specified, the term "C 1-3 alkyl" is used to represent a saturated hydrocarbon group with a straight or branched chain consisting of 1 to 3 carbon atoms. The C 1-3 alkyl includes C 1-2 and C 2-3 alkyl, etc.; it can be monovalent (such as methyl), divalent (such as methylene), or polyvalent (such as methine). Examples of C 1-3 alkyl include but are not limited to methyl (Me), ethyl (Et), propyl (including n-propyl and isopropyl), etc.

[0127] Unless otherwise specified, C n-n+m or C n -C n+m includes any specific case of having n to n + m carbons.

The dose-response relationship curve was fitted using the standard Hill equation, and the specific equation was as follows:

[0385] I (C) =I b +(I fr -I b )*c n / (IC 50 n +c n )

[0386] C is the compound test concentration, and n is the slope

[0387] Curve fitting and inhibition rate calculation were both completed by the Qpatch analysis software. If the inhibition rate at the lowest concentration exceeded half-maximal inhibition or the inhibition rate at the highest concentration did not reach half-maximal inhibition, the corresponding IC 50 of the compound was lower than the lowest concentration or the IC 50 value was greater than the highest concentration.
