Abstract

Description
Technical Field
The invention relates to a pyrimido pyrazole compound, a preparation method and application thereof.
Background
Cyclin-dependent kinases (CDKs) belong to the serine/threonine kinase family, whose monomers are not active themselves and must bind to corresponding Cyclins (Cyclins) to form active heterodimer complexes to exert a regulatory action, which can catalyze phosphorylation of corresponding substrates, directly or indirectly regulate the cells to complete the cell cycle, leading to growth and proliferation of the cells. It has now been found that the human genome encodes 21 CDKs and more than 15 Cyclins. CDKs can be divided into two major categories according to their function: CDKs that control the cell cycle and CDKs that control transcription by the cell. CDK 1/2/4/6 is mainly related to the cell cycle, while CDK7/8/9/10 is mainly related to the transcription mechanism of intracellular genetic information (Ashhar U, Witkiewicz A K, Turner N C, et al. the history and future of obtaining cycle-dependent kinases in cancer therapy. Nat Rev Drug Discov, 2015 (2): 130-). 146).
CDK7 is an important member of the CDKs family, and regulates the Cell cycle mainly through two indirect ways, namely CDK7 together with cycle H and Mat1 constitutes CAK (CDKs activating kinase), further phosphorylates CDK1/2, thereby activating their function in the Cell cycle (Yee A, Nichols MA, Wu L, Hall F L, Xiong Y.Molecular cloning of CDK7-associated human MAT1, a cycle-dependent kinase-activating kinase (CAK) activating factor. cancer Res 1995; 55: 6058-.
In recent years, inhibition of CDK7 has become a promising therapeutic strategy in many cancers, inhibition of CDK7 can inhibit expression of key oncogenes such as C-Myc and the like (Chipumuro E, Marco E, Christensen C L, Kwiatkowski N, Zhang T, Hatheway CM, et Al. CDK7 inhibition of cancer patients super-enhance-malignant transcription in MYCN-drive cancer. Cell 2014; 159: 1126-39.). preclinical studies data show that small molecule inhibitors that inhibit 7 are effective in hormone receptor positive and triple negative breast cancers (Wang Y, Zhang T, Kwiatkowski N, Abraham BJ, &TtltTtlttranslation L "= Ttgttg L/& gt/T/& gt, Ttgertner L & gt/& gt, Ttgrain J/& gt, Tjtt translation J/& gt, Tjtt 5. these approaches are likely to be effective as anticancer drugs for cancer therapy for cancer patients with different cancer resistance mechanisms such as Kpusilvictory factors and the anticancer drug resistance of cancer cells marked as Kpudendar J22. the current.
Among the reported CDK7 inhibitors are the covalent irreversible inhibitor SY1365, THZ1 of Syros. THZ1 has the structure:

The terms "neoplasm" and "tumor" are used interchangeably herein and refer to an abnormal tissue mass in which the growth of the tissue mass exceeds and is not coordinated with the growth of normal tissue. A neoplasm or tumor can be "benign" or "malignant," depending on the following characteristics: the degree of cell differentiation (including morphology and function), growth rate, local invasion, and metastasis. A "benign neoplasm" is generally well differentiated, grows characteristically slower than a malignant neoplasm, and remains localized to the site of origin. In addition, benign neoplasms do not have the ability to infiltrate, invade, or metastasize to distant sites. Exemplary benign neoplasms include, but are not limited to, lipoma, chondroma, adenoma, acrochordon, senile hemangioma, seborrheic keratosis, freckles, and sebaceous hyperplasia. In some cases, certain "benign" tumors may subsequently develop malignant neoplasms, which may be caused by additional genetic changes occurring in a subpopulation of the tumor's neoplastic cells, and these tumors are referred to as "pre-malignant neoplasms". An exemplary pre-malignant neoplasm is a teratoma. In contrast, "malignant neoplasms" are generally poorly differentiated (anaplasia) and have characteristically rapid growth with progressive infiltration, invasion, and damage to surrounding tissues. In addition, malignant neoplasms generally have the ability to metastasize to distant sites.
The term "metastasis," "metastatic," or "metastasizing" refers to the expansion of cancer cells or metastasis from a primary or primary tumor to another organ or tissue, and is generally identified by the presence of a "secondary tumor" or "secondary cell mass" of the tissue type of the primary or primary tumor and not of the organ or tissue in which the secondary (metastatic) tumor is located. For example, prostate cancer that has migrated to bone is referred to as metastatic prostate cancer and includes cancerous prostate cancer cells that grow in bone tissue.
The term "cancer" refers to a malignant tumor (Stedman 'S medical dictionary (Stedman' S medicinal Dictionary), 25th edition (25th ed), Hensyl edition; Williams and Wilkins (Williams & Wilkins: Philadelphia): Philadelphia (Philadelphia), an exemplary cancer includes but is not limited to auditory neuroma, adenocarcinoma, adrenal gland, anal carcinoma, angiosarcoma (e.g., lymphatic sarcoma, lymphatic endothelioma, angiosarcoma), benign monoclonal gammaglobular globulin disease, biliary tract tumor (e.g., cholangiocarcinoma), bladder cancer, breast cancer (e.g., adenocarcinoma, papillary carcinoma, breast cancer, medullary carcinoma), brain cancer (e.g., meningioma, glioblastoma, glioma (e.g., astrocytoma, oligodendroglioma), cervical cancer (e.g., adenocarcinoma), cervical cancer (e.g., adenocarcinoma), meningiocarcinoma, adenocarcinoma, etc.), neuroblastoma, bronchogenic carcinoma, as a bronchogenic carcinoma of the gastrointestinal tract, e, as a neuroblastoma, lung cancer (LL), as a gastrointestinal neuroblastoma, as a lymphoblastic lymphoma, as a splendid not a neuroblastoma, as a gastrointestinal neuroblastoma (LL, as a), as a neuroblastoma (epithelial carcinoma of the gastrointestinal neuroblastoma, as a), as a neuroblastoma, as a gastrointestinal neuroblastoma (LL, as a neuroblastoma, as a), as a (epithelial carcinoma of a), as a gastrointestinal neuroblastoma, as a (epithelial carcinoma of a, as a gastrointestinal neuroblastoma, as a gastrointestinal tract, as a (as a gastrointestinal neuroblastoma, as a), as a (as a), as a gastrointestinal neuroblastoma, as a, as.
The term "angiogenesis" refers to the formation and growth of new blood vessels. Normal angiogenesis occurs in the healthy body of a subject for healing wounds after injury and for restoring blood flow to tissues. The healthy body controls angiogenesis by many means, for example, angiogenesis-stimulating growth factors and angiogenesis inhibitors. Many disease states, such as cancer, blindness to diabetes, age-related macular degeneration, rheumatoid arthritis, and psoriasis, are characterized by aberrant (i.e., increased or excessive) angiogenesis. Abnormal or pathological angiogenesis refers to angiogenesis greater than that in the normal body, particularly in adults not associated with normal angiogenesis (e.g., menstruation or wound healing). Aberrant angiogenesis can provide new blood vessels that feed diseased tissues and/or destroy normal tissues, and in the case of cancer, the new vessels can allow cancer cells to escape into the circulation and lodge in other organs (tumor metastases). In certain embodiments, the angiogenesis is pathological angiogenesis.
The term "inflammatory disease" refers to a disease caused, derived or caused by inflammation. The term "inflammatory disease" may also refer to an inflammatory response that is aberrant through the regulation of macrophage, granulocyte and/or T-lymphocyte evoked amplification responses leading to aberrant tissue damage and/or cell death. Inflammatory diseases may be acute or chronic inflammatory conditions and may be caused by infectious or non-infectious causes. Inflammatory diseases include, but are not limited to, atherosclerosis, arteriosclerosis, autoimmune diseases, multiple sclerosis, systemic lupus erythematosus, polymyalgia rheumatica (PMR), gouty arthritis, degenerative arthritis, tendonitis, bursitis, psoriasis, cystic fibrosis, osteoarthritis, rheumatoid arthritis, inflammatory arthritis, sjogren's syndrome, giant cell arteritis, progressive systemic sclerosis (scleroderma), ankylosing spondylitis, polymyositis, dermatomyositis, pemphigus, pemphigoid, diabetes (e.g., type I), myasthenia gravis, hashimoto's thyroiditis, Graves 'disease, Goodpasture's disease, mixed connective tissue disease, sclerosing cholangitis, inflammatory bowel disease, Crohn's disease, ulcerative colitis, pernicious anemia, inflammatory dermatoses, interstitial pneumonia of common type (UIP), asbestosis, Crohn's disease, Graves's disease, multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, progressive systemic sclerosis, degenerative arthritis, rheumatoid arthritis, sclerosing disease, sclerosing's, Silicosis, bronchiectasis, berylliosis, talcpsis, pneumoconiosis, sarcoidosis, desquamative interstitial pneumonia, lymphatic interstitial pneumonia, giant cell interstitial pneumonia, intercellular pneumonia, exogenous allergic alveolitis, wegener's granulomatosis and the relevant forms of vasculitis (temporal arteritis and polyarteritis nodosa), inflammatory skin diseases, hepatitis, delayed hypersensitivity reactions (e.g., poison ivy dermatitis), pneumonia, airway inflammation, Adult Respiratory Distress Syndrome (ARDS), encephalitis, immediate hypersensitivity reactions, asthma, hay fever, allergy, acute hypersensitivity reactions, rheumatic fever, glomerulonephritis, pyelonephritis, cellulitis, cystitis, chronic cholecystitis, ischemia (ischemic injury), reperfusion injury, transplant rejection, host versus graft rejection, appendicitis, arteritis, blepharitis, bronchiolitis, Bronchitis, cervicitis, cholangitis, chorioamnionitis, conjunctivitis, dacryadenitis, dermatomyositis, endocarditis, endometritis, enteritis, enterocolitis, epicondylitis, epididymitis, fasciitis, fibrositis, gastritis, gastroenteritis, gingivitis, ileitis, iritis, laryngitis, myelitis, myocarditis, nephritis, omphalitis, oophoritis, orchitis, osteitis, otitis, pancreatitis, parotitis, pericarditis, pharyngitis, pleuritis, phlebitis, pneumonia, proctitis, prostatitis, rhinitis, salpingitis, sinusitis, stomatitis, synovitis, orchitis, tonsillitis, urethritis, cystitis, uveitis, vaginitis, vasculitis, vulvitis, vulvovaginitis, vasculitis, chronic bronchitis, osteomyelitis, optic neuritis, temporal arteritis, transverse myelitis, necrotizing fasciitis, and necrotizing enterocolitis.
The term "autoimmune disease" refers to a disease resulting from an inappropriate immune response of the body of a subject against substances and tissues normally present in the body. In other words, the immune system mistakes some parts of the body as pathogens and attacks its own cells. This may be limited to certain organs (e.g., in autoimmune thyroiditis) or contain specific tissues in different places (e.g., Goodpasture's disease which may affect basement membrane in both the lung and kidney). Autoimmune diseases are typically treated with immunosuppression (e.g., drugs that reduce the immune response). Exemplary autoimmune diseases include, but are not limited to, glomerulonephritis, goodpasture's syndrome, necrotizing vasculitis, lymphadenitis, periarticular inflammatory polyarteritis, systemic lupus erythematosus, rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, psoriasis, ulcerative colitis, systemic sclerosis, dermatomyositis/polymyositis, antiphospholipid antibody syndrome, scleroderma, pemphigus vulgaris, ANCA-related vasculitis (e.g., wegener's granulomatosis, microscopic polyangiitis), uveitis, sjogren's syndrome, crohn's disease, reiter's syndrome, ankylosing spondylitis, lyme arthritis, guillain-barre syndrome, hashimoto's thyroiditis, and cardiomyopathy.
The term "autoinflammatory disease" refers to a similar but different disease classification than autoimmune disease. Both autoinflammatory and autoimmune diseases share the same feature, i.e. both groups of disorders result from the immune system attacking the subject's own tissues and leading to increased inflammation. In idiopathic inflammatory diseases, the innate immune system of a subject causes inflammation of unknown origin. The innate immune system reacts, although in subjects it never encounters autoantibodies or antigens. Spontaneous inflammatory disorders are characterized by a strong onset of inflammation that leads to such symptoms as fever, rash, or joint swelling. These diseases can also carry the risk of amyloidosis, a potentially fatal accumulation of blood proteins in vital organs. Autoinflammatory diseases include, but are not limited to, Familial Mediterranean Fever (FMF), neonatal onset multiple system inflammatory disease (NOMID), Tumor Necrosis Factor (TNF) receptor-associated periodic syndrome (TRAPS), interleukin 1 receptor antagonist (DIRA) deficiency, and behcet's disease.
The term "kinase" refers to any enzyme that catalyzes the addition of phosphate groups to amino acid residues of proteins. For example, serine kinases catalyze the attachment of phosphate groups to proteinsExamples of kinases include, but are not limited to, CMGC kinases (e.g., cyclin-dependent kinases (CDKs, e.g., CDK1, CDK2, CDK2, CDK4, CDK5, CDK7, CDK8, CDK9, CDK10, CDK11, CDK12, CDK13, CDK14, CDK16, CDK20), mitogen protein kinases (MAPKs, e.g., MAPK1, MAPK3, MAPK4, MAPK6, MAPK7, glycogen synthase kinase 3(GSK 7, e.g., GSK 7), or CDC-like kinases (e.g., CDC 7, pkc 7), pkc 7, pkc 362+Calponin-dependent protein kinases (CaM kinases, e.g., specialized CaM kinase, multifunctional CaM kinase), casein kinase 1(CK1, e.g., CK1 α, CK1 β 1, CK1 γ 1, CK1 γ 2, CK1 γ 3, CK1, CK1), STE kinase (e.g., sterilized yeast homolog 7, sterilized yeast homolog 11, or sterilized yeast homolog 20 kinase), tyrosine kinase (TK, e.g., Receptor Tyrosine Kinase (RTK), non-receptor tyrosine kinase (nRTK)), and tyrosine kinase-like kinase (TK L, e.g., mixed lineage kinase (M L K), RAF, Serine Threonine Kinase Receptor (STKR), leucine-rich repeat kinase (L RRK), L IM domain kinase (L IMK), testis-expressing serine kinase (TESK), I L1 receptor-associated kinase (irrak), Receptor Interacting Protein Kinase (RIPK)).
The term "CDK" refers to a cyclin-dependent kinase. The CDK binds to cyclin (e.g., cyclin H), which is a regulatory protein. CDKs phosphorylate serine and threonine on substrates. The consensus sequence for the phosphorylation site in the amino acid sequence of the CDK substrate is [ S/T ] PX [ K/R ], wherein S/T is phosphorylated serine or threonine, P is proline, X is any amino acid, K is lysine, and R is arginine. CDKs include CDK1, CDK2, CDK2, CDK4, CDK5, CDK7, CDK8, CDK9, CDK10, CDK11, CDK12, CDK14, CDK16, and CDK 20. CDK7 is a CDK in which the substrate is cyclin H, MAT1 (e.g., MNAT1), or cyclin H and MAT 1.

When no atom is indicated in the listed substituents for connecting to a compound included in the general chemical structure but not specifically mentioned, such substituent may be bonded through any atom thereof. Combinations of substituents and/or variants thereof are permissible only if such combinations result in stable compounds.
When no substituent is specifically indicated in the listed group, such group is simply referred to as unsubstituted. For example when "C1~C4When an alkyl group is "without the limitation of" substituted or unsubstituted ", it means only" C1~C4Alkyl "by itself or unsubstituted C1~C4Alkyl groups ".
In each of the parts of the invention, linking substituents are described. Where the structure clearly requires a linking group, the markush variables listed for that group are understood to be linking groups.
