Definitions

  • the present invention relates to a series of heterocyclic substituted pyrimidine derivatives, in particular to compounds represented by formula (I) and pharmaceutically acceptable salts thereof.
  • Mitogen-activated protein kinases mitogen-activated protein kinases
  • MAPK mitogen-activated protein kinases
  • the MAPKs family includes four subfamilies of ERK, p38, JNK and ERK5. There are differences in the function of each MAPK subfamily. ERKs are the main regulators of growth-related stimuli, JNK is activated under stimuli such as hyperosmotic pressure and strong oxidative conditions, ERK5/BMK1 regulates the early expression of certain genes, and p38 can participate in inflammation, cell growth, and cell differentiation , cell cycle and cell death and many other physiological processes.
  • the biochemical characteristic of MAPKs is that after receiving certain stimuli, the two sites of threonine and tyrosine will be phosphorylated and activated.
  • MAPKs Downstream substrates of MAPKs include mitogen-activated protein kinase-activated protein (MAPKAP) kinases and transcription factors, whose phosphorylation directly or indirectly regulates gene expression at several points, including transcription, nuclear export, and mRNA stability and translation .
  • MAPK activation include inflammation, apoptosis, differentiation and proliferation.
  • Different genes encode the four p38MAPK kinases in humans: p38 ⁇ , p38 ⁇ , p38 ⁇ and p38 ⁇ . Significant amino acid sequence homology was observed between the 4 isoforms with 60%-75% overall sequence identity and >90% identity within the kinase domain.
  • P38 ⁇ is a key isoform in the MAPK signaling pathway that regulates cytokine production.
  • MK2 (MAPKAK2) is one of the main downstream proteins of P38. Activated MK2 can phosphorylate the AU-rich element binding protein TTP, regulate the stability of TNF- ⁇ , IL-1 ⁇ , IL-6 and other cytokine mRNAs, and regulate the factor biosynthesis.
  • Rheumatoid arthritis is a systemic, autoimmune, chronic inflammatory disorder characterized by inflammation of the synovial membrane of joints, leading to destruction of cartilage and bone.
  • Current treatments for RA include oral disease-modifying antirheumatic drugs (DMARDs) (methotrexate, leflunomide, sulfasalazine) and parenteral administration of biologic agents, particularly targeting IL-1 ⁇ or TNF- ⁇ , which Two key pro-inflammatory cytokines involved in RA pathogenesis.
  • DMARDs oral disease-modifying antirheumatic drugs
  • DMARDs metalhotrexate, leflunomide, sulfasalazine
  • parenteral administration of biologic agents particularly targeting IL-1 ⁇ or TNF- ⁇ , which Two key pro-inflammatory cytokines involved in RA pathogenesis.
  • the superior efficacy of these latter agents is somewhat offset by potential disadvantages including the need for parenteral administration, difficulty in dose adjustment, poor reversibility due to long plasma half-life
  • Orally administered DMARDs with improved efficacy therefore offer multiple advantages to patients and physicians in terms of ease and compliance of administration, absence of injection site/allergic reactions, superior dose scalability, and favorable cost of goods. Therefore, the development of safe, effective and orally available MK2 inhibitors still has extensive clinical needs.

细胞对外界刺激的响应是由一系列胞内的激酶以及磷酸酶调控的。这一类酶催化的磷酸化或去磷酸化反应可以调控其下游各个成分的活性、与其他蛋白的相互作用、在细胞内的位置等。丝裂原活化蛋白激酶(mitogen-activated protein kinases,MAPK)是信号从细胞表面传导到细胞核内部的重要传递者，是一组能被不同的细胞外刺激，如细胞因子、神经递质、激素、细胞应激及细胞黏附等激活的丝氨酸-苏氨酸蛋白激酶。MAPKs家族包括ERK、p38、JNK和ERK5四个亚家族。每个MAPK的亚家族之间的功能存在着差异。ERKs是主要的生长相关刺激的调控者，JNK在受到高渗透压和强氧化条件等刺激下被激活，ERK5/BMK1调控某些基因的早期表达，p38则可以参与到炎症、细胞生长、细胞分化、细胞周期和细胞死亡等多个生理过程中。MAPKs的生化特点是在受到某些刺激后，其苏氨酸和酪氨酸两个位点会被磷酸化从而被激活。The response of cells to external stimuli is regulated by a series of intracellular kinases and phosphatases. The phosphorylation or dephosphorylation reaction catalyzed by this type of enzyme can regulate the activity of its downstream components, the interaction with other proteins, and its location in the cell. Mitogen-activated protein kinases (mitogen-activated protein kinases, MAPK) is an important transmitter of signals from the cell surface to the inside of the nucleus, and is a group that can be stimulated by different extracellular stimuli, such as cytokines, neurotransmitters, hormones, Serine-threonine protein kinase activated by cellular stress and cell adhesion. The MAPKs family includes four subfamilies of ERK, p38, JNK and ERK5. There are differences in the function of each MAPK subfamily. ERKs are the main regulators of growth-related stimuli, JNK is activated under stimuli such as hyperosmotic pressure and strong oxidative conditions, ERK5/BMK1 regulates the early expression of certain genes, and p38 can participate in inflammation, cell growth, and cell differentiation , cell cycle and cell death and many other physiological processes. The biochemical characteristic of MAPKs is that after receiving certain stimuli, the two sites of threonine and tyrosine will be phosphorylated and activated.
MAPK的下游底物包括丝裂原活化蛋白激酶激活的蛋白(MAPKAP)激酶和转录因子，其磷酸化直接或间接地调节几个点的基因表达，包括转录、核输出及mRNA的稳定性和翻译。MAPK激活的细胞影响包括炎症、细胞凋亡、分化及增殖。不同的基因编码人体内的四种p38MAPK激酶：p38α、p38β、p38γ及p38δ。在4个亚型间观察到了显著的氨基酸序列同源性，所述亚型具有60％-75％的整体序列同一性，在激酶结构域内具有>90％的同一性。还观察到了组织选择性表达，其中p38γ主要存在于骨骼肌中，p38δ主要存在于睾丸、胰腺及小肠中。相比之下，p38α和p38β表达更加广泛。P38α是MAPK信号通路中调节细胞因子产生的关键亚型。Downstream substrates of MAPKs include mitogen-activated protein kinase-activated protein (MAPKAP) kinases and transcription factors, whose phosphorylation directly or indirectly regulates gene expression at several points, including transcription, nuclear export, and mRNA stability and translation . The cellular effects of MAPK activation include inflammation, apoptosis, differentiation and proliferation. Different genes encode the four p38MAPK kinases in humans: p38α, p38β, p38γ and p38δ. Significant amino acid sequence homology was observed between the 4 isoforms with 60%-75% overall sequence identity and >90% identity within the kinase domain. Tissue-selective expression was also observed, in which p38γ mainly exists in skeletal muscle, and p38δ mainly exists in testis, pancreas and small intestine. In contrast, p38α and p38β are more widely expressed. P38α is a key isoform in the MAPK signaling pathway that regulates cytokine production.
MK2(MAPKAK2)是P38的主要下游蛋白之一，激活的MK2可以磷酸化AU-rich元件结合蛋白TTP，调控TNF-α、IL-1β、IL-6等细胞因子mRNA的稳定性，调节这些细胞因子的生物合成。MK2 (MAPKAK2) is one of the main downstream proteins of P38. Activated MK2 can phosphorylate the AU-rich element binding protein TTP, regulate the stability of TNF-α, IL-1β, IL-6 and other cytokine mRNAs, and regulate the factor biosynthesis.
类风湿性关节炎(RA)是系统性的、自身免疫的慢性炎症性病症，其特征在于关节滑膜炎症，从而导致软骨和骨骼破坏。目前的RA的治疗包括口服调节病情抗风湿药物(DMARD)(甲氨蝶呤、来氟米特、柳氮磺吡啶)和肠胃外施用生物药剂，特别是针对IL-1β或TNF-α，这两种RA发病机制中涉及到的关键的促炎性细胞因子。后者这些药剂的优越功效被潜在的缺点稍微抵消，所述缺点包括需要肠胃外施用、难以调整剂量、由于较长的血浆半衰期导致的可逆性差、诱导宿主中和抗体反应及高的治疗费用。因此口服施用的具有改 善功效的DMARD就施用的便利性和依从性，没有注射部位/过敏反应，优越的剂量可调整性及有利的物品成本而言为患者和医师提供多种优势。因此，开发安全有效可口服的MK2抑制剂仍然具有广泛的临床需求。Rheumatoid arthritis (RA) is a systemic, autoimmune, chronic inflammatory disorder characterized by inflammation of the synovial membrane of joints, leading to destruction of cartilage and bone. Current treatments for RA include oral disease-modifying antirheumatic drugs (DMARDs) (methotrexate, leflunomide, sulfasalazine) and parenteral administration of biologic agents, particularly targeting IL-1β or TNF-α, which Two key pro-inflammatory cytokines involved in RA pathogenesis. The superior efficacy of these latter agents is somewhat offset by potential disadvantages including the need for parenteral administration, difficulty in dose adjustment, poor reversibility due to long plasma half-life, induction of host neutralizing antibody responses, and high treatment costs. Orally administered DMARDs with improved efficacy therefore offer multiple advantages to patients and physicians in terms of ease and compliance of administration, absence of injection site/allergic reactions, superior dose scalability, and favorable cost of goods. Therefore, the development of safe, effective and orally available MK2 inhibitors still has extensive clinical needs.

If tautomerism is possible (eg, in solution), then chemical equilibrium of the tautomers can be achieved. For example, proton tautomers (also called prototropic tautomers) include interconversions via migration of a proton, such as keto-enol isomerization and imine-ene Amine isomerization. Valence isomers (valence tautomers) involve interconversions by recombination of some bonding electrons. A specific example of keto-enol tautomerization is the interconversion between two tautomers of pentane-2,4-dione and 4-hydroxypent-3-en-2-one.

For example, compounds may be labeled with radioactive isotopes such as tritium ( 3 H), iodine-125 ( 125 I) or C-14 ( 14 C). For another example, heavy hydrogen 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 non-deuterated drugs, deuterated drugs can reduce toxic side effects and increase drug stability. , enhance the efficacy, prolong the biological half-life of drugs and other advantages. All changes in isotopic composition of the compounds of the invention, whether radioactive or not, are included within the scope of the invention.

术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代，取代基可以包括重氢和氢的变体，只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即＝O)时，意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代，也可以不被取代，除非另有规定，取代基的种类和数目在化学上可以实现的基础上可以是任意的。The term "substituted" means that any one or more hydrogen atoms on a specified atom are replaced by a substituent, which may include deuterium and hydrogen variants, as long as the valence of the specified atom is normal and the substituted compound is stable. When a substituent is oxygen (ie =0), it means that two hydrogen atoms are replaced. Oxygen substitution does not occur on aromatic groups. The term "optionally substituted" means that it may or may not be substituted, and unless otherwise specified, the type and number of substituents may be arbitrary on a chemically realizable basis.
当任何变量(例如R)在化合物的组成或结构中出现一次以上时，其在每一种情况下的定义都是独立的。因此，例如，如果一个基团被0-2个R所取代，则所述基团可以任选地至多被两个R所取代，并且每种情况下的R都有独立的选项。此外，取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。When any variable (eg, R) occurs more than once in the composition or structure of a compound, its definition is independent at each occurrence. Thus, for example, if a group is substituted with 0-2 R, said group may optionally be substituted with up to two R, with independent options for each occurrence of R. Also, combinations of substituents and/or variations thereof are permissible only if such combinations result in stable compounds.
当一个连接基团的数量为0时，比如-(CRR) 0-，表示该连接基团为单键。 When the number of a linking group is 0, such as -(CRR) 0 -, it means that the linking group is a single bond.
当其中一个变量选自单键时，表示其连接的两个基团直接相连，比如A-L-Z中L代表单键时表示该结构实际上是A-Z。When one of the variables is selected from a single bond, it means that the two groups connected are directly connected. For example, when L in A-L-Z represents a single bond, it means that the structure is actually A-Z.
除非另有规定，当某一基团具有一个或多个可连接位点时，该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的，且可连接位点存在H原子时，则连接化学键时，该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键

When the connection method of the chemical bond is not positioned, and there is an H atom at the connectable site, when the chemical bond is connected, the number of H atoms at the site will decrease correspondingly with the number of chemical bonds connected to become the corresponding valence group. The chemical bonds that the site connects with other groups can use straight solid line bonds
