Abstract
Description
Technical Field
[0001] This invention relates to a quinazoline derivative or stereoisomer, pharmaceutically acceptable salt, solvate, or tautomer, and its use in CDK9 and / or TNIK-mediated diseases. Background Technology
[0002] Aberrant activation of the Wnt signaling pathway has been observed in various human cancers, including colorectal cancer, pancreatic cancer, non-small cell lung cancer, and prostate cancer. Approximately 90% of colorectal cancers exhibit mutations in at least one Wnt pathway regulator, such as the adenomatous polyposis (APC) and β-catenin (CTNNB1) genes. These mutations lead to the intracellular accumulation of β-catenin and its translocation to the nucleus, stimulating the TCF4 / LEF family transcription factors to activate numerous genes involved in intestinal epithelial cell proliferation, differentiation, and death, such as MYC, CCND1, AXIN, and JUN, driving tumor development and progression. Therefore, inhibiting aberrant activation of the Wnt pathway is an effective strategy for treating colorectal cancer. In the classic Wnt pathway, the Traf2- and NCK-interacting protein kinase (TNIK) has been identified as a crucial component of the transcriptional regulatory complex of Wnt target genes. It interacts directly with TCF4 in a β-catenin-dependent manner, activating TCF4 / LEF-driven transcription of Wnt target genes through TCF4 phosphorylation, leading to Wnt signaling transduction within tumor cells. As the downstream transcriptional regulator of the Wnt pathway, TNIK plays a vital role in activating the Wnt signaling pathway and maintaining the growth of colorectal cancer cells. Inhibiting TNIK is expected to block the aberrant transduction of Wnt signaling in colorectal cancer cells, suggesting that TNIK may be a potential drug target for treating colorectal cancers with abnormal Wnt signaling pathways.
[0003] Cyclin-dependent kinase 9 (CDK9) is a serine / threonine protein kinase that typically forms a heterodimeric complex with its intracellular counterpart, cyclin cyclin, regulating cellular transcription. Increasing research indicates that CDK9 is highly expressed in various malignant tumors and is associated with poor cancer prognosis. As an important component of positive transcription elongation factor P-TEFb, the CDK9 / Cyclin T1 complex activates the transcriptional elongation of genes regulating cell proliferation, development, and stress, such as MYC, nuclear factor-κB (NF-κB), and MCL1, by specifically phosphorylating the negative elongation factor NELF, DRB sensitivity-inducing factor DSIF, and the Ser2 residue at the CTD end of RNA polymerase II (Pol II). This promotes tumorigenesis and development. Inhibiting CDK9 can block the phosphorylation activation of RNA Pol II by P-TEFb, inhibit transcriptional elongation, reduce the mRNA levels of oncogenes such as MYC in cells, and downregulate the expression of anti-apoptotic genes, thereby preventing tumor cell proliferation and inducing tumor cell apoptosis. Therefore, the specific regulatory role of CDK9 in the transcriptional process makes it one of the most promising anti-tumor targets in the CDK family.
[0004] WO2007117607 reported a quinazoline compound with a structure targeting PDK1 inhibitors, but no evidence of its inhibitory effect on CDK9 has been shown. Furthermore, drug research on CDK9 is scarce, with the vast majority being non-selective inhibitors. Common examples of non-selective CDK9 inhibitors include P276-00, SCH727965, or AT7519. Non-selective inhibitors have significant toxic side effects during use, such as neutropenia and thrombocytopenia.
[0005] Currently, there are also research reports on the Wnt transmission pathway. CN201380026183.8 discloses the use of bicyclic thiazole compounds as TNIK inhibitors, and CN201980015875.X reports the use of heterocyclic fused phenyl compounds for TNIK inhibition. However, there are few reports on the use of quinazoline derivatives as TNIK inhibitors, especially those involving selective inhibition of TNIK and / or CDK9 targets.
[0006] Therefore, developing a class of highly active inhibitors that selectively inhibit CDK9 and / or TNIK targets is an urgent technical challenge that needs to be addressed. Summary of the Invention

[0146]
[0147] The preferred structure is a saturated, non-aromatic monocyclic structure containing one or more heteroatoms.
[0148] The term "aryl" refers to a monocyclic or fused polycyclic (i.e., a ring sharing adjacent carbon atom pairs) group having a conjugated π-electron system and 6 to 14 carbon atoms (6 to 14 members). Illustrative aryl groups include, but are not limited to, phenyl, naphthyl, and anthracene. Phenyl is preferred.
[0149] The term "heteroaryl" refers to a heteroaryl system comprising 1 to 4 (e.g., 1, 2, 3, or 4) heteroatoms and 5 to 14 ring atoms (e.g., 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14), wherein the heteroatoms are selected from O, S, or N. Illustrative examples of heteroaryls include entities in the form of suitable bonded portions:
[0150]
[0151] The heteroaryl group is preferably 5 to 10 membered, containing 1 to 3 heteroatoms; preferably 5 or 6 membered, containing 1 to 3 heteroatoms; more preferably 6 membered heteroaryl, such as pyridyl, pyrimidinyl, pyrazinyl, etc.
[0152] The term "alkenyl" refers to a straight-chain, branched, or cyclic hydrocarbon group containing 2 to 12 carbon atoms and having one or more double bonds. For example, C2-C7 alkenyl groups refer to those containing 2-7 carbon atoms, which can be vinyl groups with 2 carbon atoms, allyl groups with 3 carbon atoms, etc. Alkenyl groups can be terminal or non-terminated, and can be unsubstituted or substituted as described by alkyl groups or as described in the various examples provided herein. This term includes cis and trans isomers and mixtures thereof.
[0153] The term "alkynyl" refers to a straight-chain or branched hydrocarbon group having 2 to 12 carbon atoms in the chain and having one or more triple bonds. The alkynyl group may be unsubstituted or substituted as described with respect to alkyl groups or as described in the various examples provided herein.
[0154] In compound structures, "*" indicates that the atom at that location has a chiral center; in compound structures Such as structure This indicates that compounds containing this structure can exist in either the R or S configuration.
[0155] "Substitution" refers to one or more hydrogen atoms in a group, preferably up to five (e.g., 1, 2, 3, 4, 5), more preferably 1 to 3 hydrogen atoms that can be independently replaced by the corresponding number of substituents. It goes without saying that substituents are only in their possible chemical positions, and those skilled in the art can determine (through experiment or theory) possible or impossible substitutions without much effort.
[0156] "Optionally" means that the events or circumstances described below may or may not occur, and the description includes both the possibility that the events or circumstances have occurred and the possibility that they have not occurred. For example, "wherein each hydrogen atom in the C1-C6 alkyl, 5-6 aryl, and 5-6 heteroaryl groups is optionally independently substituted by a C1-C6 alkyl group" means that the alkyl group may or may not be present on any of the C1-C6 alkyl, 5-6 aryl, and 5-6 heteroaryl groups by substituting hydrogen atoms of the alkyl group.
[0157] "Independently" means that the event or situation described below should be understood in itself with respect to other similar events or circumstances. For example, "independently" means that each hydrogen atom on a group can be substituted by another group, wherein the groups substituting for each hydrogen atom can be the same or different. Or, for example, if there are multiple groups, each of which can be selected from the group of possibilities, then using "independently" means that each group can be selected from the group of possibilities independently of any other group, and the groups selected in the case can be the same or different.
[0158] The term "stereoisomer" as used in this invention refers to the presence of a compound containing one or more asymmetric centers, which can exist as a racemic mixture and a mixture thereof, a single enantiomer, a mixture of diastereomers, and a single diastereomer. Compounds of this invention may have asymmetric centers, resulting in two optical isomers. The scope of this invention includes all possible optical isomers and mixtures thereof. If the compounds of this invention contain an olefin double bond, the scope of this invention includes cis and trans isomers unless otherwise specified. Compounds of this invention can exist as tautomers (a type of functional group isomer) having different hydrogen connection points through one or more double bond shifts; for example, a ketone and its enol form are keto-enol tautomers. All tautomers and mixtures thereof are within the scope of this invention. Enantiomers of all compounds. Diastereomers, racemates, mesomates, cis-trans isomers, tautomers, geometric isomers, epimers, and mixtures thereof are all within the scope of this invention.
[0159] The term “compounds of the present invention” is intended to cover compounds of general formula (I) as defined herein, or any preferred or specific embodiment thereof (including compounds of formula (Ia) and the example compounds), their stereoisomers, pharmaceutically acceptable salts, tautomers or solvates.
[0160] The term "pharmaceutically acceptable" means a molecular entity or composition that is approved or can be approved by the relevant authorities of each country, or is listed in a generally accepted pharmacopoeia for use in animals, and more specifically in humans, or that will not produce adverse, allergic, or other adverse reactions when administered appropriately to animals, such as humans. Specifically, such salts are non-toxic and may be addition salts of inorganic acids, organic acids, or bases.
[0161] The “pharmaceutical composition” of this invention refers to a composition comprising one or more compounds of formula (I), formula (Ia) or their stereoisomers, tautomers, pharmaceutically acceptable salts or solvates, and a carrier or excipient generally accepted in the art for delivering a bioactive compound to an organism (e.g., a human).
[0162] The pharmaceutical compositions of the present invention can be formulated using techniques known to those skilled in the art, such as those disclosed in the 20th edition of Remington's Pharmaceutical Sciences. The pharmaceutical compositions of the present invention can be prepared by mixing the compounds of the present invention or pharmaceutically acceptable salts thereof with one or more pharmaceutically acceptable excipients. Preparation may further include the step of mixing one or more other active ingredients with the compounds of the present invention and one or more pharmaceutically acceptable excipients.
[0163] The selection of pharmaceutically acceptable excipients in this invention depends on a variety of factors, such as the route of administration and the form of the composition provided. Suitable pharmaceutically acceptable excipients are well known to those skilled in the art and described, for example, in Ansel, Howard C., et al., Ansel's Pharmaceutical Dosage Forms and Drug Delivery Systems. Philadelphia Lippincott, Williams & Wikins, 2004, and include, for example, adjuvants, diluents (e.g., glucose, lactose, or mannitol), carriers, pH adjusters, buffers, sweeteners, fillers, stabilizers, surfactants, wetting agents, lubricants, emulsifiers, suspending agents, preservatives, antioxidants, opacifiers, flow aids, processing aids, colorants, flavorings, diluents, binders, and other known additives.
[0164] The pharmaceutical compositions of the present invention can be administered in a standard manner. Suitable administration methods include, for example, oral, intravenous, rectal, parenteral, topical, transdermal, ocular, nasal, buccal, or pulmonary (inhalation) administration; wherein parenteral administration includes intramuscular, intravenous, intra-arterial, intraperitoneal, or subcutaneous administration. For these purposes, the compounds of the present invention can be formulated into tablets, capsules, syrups, powders, granules, aqueous or oily solutions or suspensions, (lipid) emulsions, dispersible powders, suppositories, ointments, creams, drops, aerosols, dry powder injections, and sterile injectable aqueous or oily solutions or suspensions by methods known in the art. The compounds of the present invention, or pharmaceutically acceptable salts thereof, can be formulated into solutions, emulsions, suspensions, or dispersions in suitable pharmaceutical solvents or carriers, or formulated with pharmaceutically acceptable excipients, into commonly used pharmaceutically acceptable dosage forms, according to conventional methods known in the art for preparing various dosage forms.
[0165] The preventive or therapeutic dose of the compounds of this invention will vary depending on a range of factors, including the individual being treated, the severity of the condition or illness, the rate of administration, the disposal of the compound, and the prescribing physician's judgment. Generally, the effective dose is from about 0.0001 to about 5000 mg per kg of body weight per day, for example, from about 0.01 to about 1000 mg / kg / day (single or divided doses). For a 70 kg person, this would total from about 0.007 mg / day to about 7000 mg / day, for example, from about 0.7 mg / day to about 1500 mg / day. Depending on the administration method, the content or amount of the compound of the present invention in the pharmaceutical composition can be from about 0.01 mg to about 1000 mg, suitably 0.1-500 mg, preferably 0.5-300 mg, more preferably 1-150 mg, particularly preferably 1-50 mg, such as 1.5 mg, 2 mg, 4 mg, 10 mg, 25 mg, etc.; accordingly, the pharmaceutical composition of the present invention will contain 0.05 to 99% w / w (weight percentage), such as 0.05 to 80% w / w, such as 0.10 to 70% w / w, such as 0.10 to 50% w / w of the compound of the present invention, all weight percentages are based on the total composition. It should be understood that it may be necessary to use doses exceeding these limits in certain circumstances.
[0166] It should be understood that the compound structures and functional groups of the present invention conform to the rules of chemical valence bonds. Some functional groups or structures have had their connecting bonds omitted in writing. For example, in some cases, X2 / X3 / X4 / X5 in formula (Ia) are selected from N, and based on the general formula structure, X2 / X3 / X4 / X5 is =N-. Additionally, in the present invention, substituents such as =NR... b Based on the general formula structure, NR b =NR b Other groups can be understood and explained in a similar way.
[0167] The present invention also includes compounds identical to those described herein, but in which one or more atoms are labeled with isotopes whose atomic weights or mass numbers differ from those commonly found in nature. Examples of isotopes that can be incorporated into compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, iodine, and chlorine, such as 2H, 3H, 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 31P, 32P, 35S, 18F, 123I, 125I, and 36Cl, respectively.
[0168] Certain isotopically labeled compounds of this disclosure (e.g., those labeled with 3H and 14C) can be used in the analysis of compound and / or substrate tissue distribution. Tritium (i.e., 3H) and carbon-14 (i.e., 14C) isotopes are particularly preferred due to their ease of preparation and detectability. Positron emission isotopes, such as 15O, 13N, 11C, and 18F, can be used in positron emission tomography (PET) studies to determine substrate occupancy. Isotopically labeled compounds of this disclosure can generally be prepared by replacing unlabeled reagents with isotopically labeled reagents.
[0169] Furthermore, substitution with a heavier isotope (such as deuterium (i.e., 2H)) can provide certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dose requirements), and may therefore be preferred in certain situations, where the deuterium substitution can be partial or complete, with partial deuterium substitution referring to at least one hydrogen being replaced by at least one deuterium.
[0170] Obviously, based on the above description of the present invention, and using common technical knowledge and methods in the field, various other modifications, substitutions, or alterations can be made without departing from the basic technical concept of the present invention.
