技术领域technical field
本发明涉及一类苯并螺杂环衍生物及其应用,具体涉及式(II)所示化合物或其药学上可接受的盐。The present invention relates to a class of benzospiro heterocyclic derivatives and applications thereof, in particular to compounds represented by formula (II) or pharmaceutically acceptable salts thereof.
背景技术Background technique
前列腺素E2(PGE2)广泛参与机体免疫调节。机体在炎症状态下产生高浓度的PGE2,引起炎症、水肿和疼痛。PGE2还参与各种生理和/或病理症状,如痛觉过敏、子宫收缩、消化道蠕动、抑制胃酸分泌、降低血压等。PGE2有4种受体(EP1、EP2、EP3、EP4),其中EP4在PGE2介导的生物学效应中发挥着重要作用。研究表明PGE2/EP4与肿瘤的发生发展有密切关系。肿瘤组织会分泌较多的PGE2。PGE2与EP4结合,可以激活PKA,磷酸化转录因子CREB;PKA也可以通过抑制GSK3,上调WNT/β-catenin和NOTCH通路活性;EP4还可激活非经典的PI3K/Akt、ERK信号通路。上述信号通路的异常可以促进细胞的存活、增殖和转移,促进肿瘤的发生发展。此外,PGE2可以通过EP4受体促进免疫抑制性细胞分化,抑制免疫效应细胞的抗肿瘤作用,介导肿瘤微环境的免疫抑制作用。近年来,EP4选择性拮抗剂在肿瘤免疫治疗中的应用受到重视。研究证实,EP4选择性拮抗剂可以抑制单核细胞向免疫抑制性细胞分化,减少肿瘤组织中免疫抑制性的细胞,如髓源抑制性细胞(MDSCs)和M2型巨噬细胞,增加肿瘤组织中的抗肿瘤免疫细胞,如树突状细胞(DCs)、T细胞和M1型巨噬细胞,进而逆转肿瘤微环境免疫抑制。目前已有多个EP4选择性拮抗剂处于针对肿瘤、炎症、疼痛等疾病治疗的临床试验阶段。ONO-4578(专利:WO2016111347、CN107108480)是其中之一,目前正在开展单药或与PD1单抗联用于实体瘤治疗的临床I/II期试验。EP4选择性拮抗剂在肿瘤、炎症、疼痛等疾病的治疗方面有很大的应用前景和临床价值,因此,有必要开发结构新颖的EP4选择性拮抗剂用于上述疾病的治疗。Prostaglandin E2 (PGE2) is widely involved in immune regulation of the body. The body produces high concentrations of PGE2 in an inflammatory state, causing inflammation, edema and pain. PGE2 is also involved in various physiological and/or pathological symptoms, such as hyperalgesia, uterine contraction, digestive tract peristalsis, inhibition of gastric acid secretion, and lowering of blood pressure. PGE2 has four receptors (EP1, EP2, EP3, EP4), among which EP4 plays an important role in the biological effects mediated by PGE2. Studies have shown that PGE2/EP4 is closely related to the occurrence and development of tumors. Tumor tissue will secrete more PGE2. The combination of PGE2 and EP4 can activate PKA and phosphorylate the transcription factor CREB; PKA can also increase the activity of WNT/β-catenin and NOTCH pathways by inhibiting GSK3; EP4 can also activate non-canonical PI3K/Akt and ERK signaling pathways. The abnormality of the above signaling pathways can promote cell survival, proliferation and metastasis, and promote the occurrence and development of tumors. In addition, PGE2 can promote the differentiation of immunosuppressive cells through the EP4 receptor, inhibit the anti-tumor effect of immune effector cells, and mediate the immunosuppressive effect of the tumor microenvironment. In recent years, the application of EP4 selective antagonists in tumor immunotherapy has received attention. Studies have confirmed that EP4 selective antagonists can inhibit the differentiation of monocytes into immunosuppressive cells, reduce immunosuppressive cells in tumor tissues, such as myeloid-derived suppressor cells (MDSCs) and M2 macrophages, and increase tumor tissue Antitumor immune cells, such as dendritic cells (DCs), T cells, and M1 macrophages, reverse the immune suppression in the tumor microenvironment. Currently, several EP4 selective antagonists are in clinical trials for the treatment of tumors, inflammation, pain and other diseases. ONO-4578 (patent: WO2016111347, CN107108480) is one of them, and is currently conducting phase I/II clinical trials of single drug or in combination with PD1 monoclonal antibody for the treatment of solid tumors. EP4 selective antagonists have great application prospects and clinical value in the treatment of tumors, inflammation, pain and other diseases. Therefore, it is necessary to develop EP4 selective antagonists with novel structures for the treatment of the above diseases.

The present invention contemplates all such compounds, including cis and trans isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers isomers, (D)-isomers, (L)-isomers, and their racemic and other mixtures, such as enantiomerically or diastereomerically enriched mixtures, all of which are within the scope of the present invention. Additional asymmetric carbon atoms may be present in substituents such as alkyl groups. All such isomers, as well as mixtures thereof, are included within the scope of the present invention.
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。Unless otherwise stated, the terms "enantiomer" or "optical isomer" refer to stereoisomers that are mirror images of each other.
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。Unless otherwise stated, the terms "cis-trans isomers" or "geometric isomers" arise from the inability to rotate freely due to the double bond or the single bond of the carbon atoms forming the ring.
除非另有说明,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。Unless otherwise indicated, the term "diastereoisomer" refers to stereoisomers whose molecules have two or more chiral centers and which are not mirror images of the molecules.

本发明的化合物可以存在特定的。除非另有说明,术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。若互变异构体是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。Compounds of the invention may exist specific. Unless otherwise stated, the term "tautomer" or "tautomeric form" means that isomers with different functional groups are in dynamic equilibrium at room temperature and are rapidly interconvertible. 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.
除非另有说明,术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100%,并且,该异构体或对映体的含量大于等于60%,或者大于等于70%,或者大于等于80%,或者大于等于90%,或者大于等于95%,或者大于等于96%,或者大于等于97%,或者大于等于98%,或者大于等于99%,或者大于等于99.5%,或者大于等于99.6%,或者大于等于99.7%,或者大于等于99.8%,或者大于等于99.9%。Unless otherwise stated, the terms "enriched in an isomer", "enriched in an isomer", "enriched in an enantiomer" or "enantiomerically enriched" refer to one of the isomers or enantiomers The content of the enantiomer is less than 100%, and the content of the 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%.
除非另有说明,术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如,其中一种异构体或对映体的含量为90%,另一种异构体或对映体的含量为10%,则异构体或对映体 过量(ee值)为80%。Unless otherwise stated, the terms "isomer excess" or "enantiomeric 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 other isomer or enantiomer is 10%, then the isomer or enantiomeric excess (ee value) is 80% .
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚(
3H),碘-125(
125I)或C-14(
14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
Optically active (R)- and (S)-isomers as well as 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 invention is desired, it can be prepared by asymmetric synthesis or derivatization with chiral auxiliary agents, wherein the resulting diastereomeric mixture is separated and the auxiliary group is cleaved to provide 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), a diastereoisomeric salt is formed with an appropriate optically active acid or base, and then a diastereomeric salt is formed by a conventional method known in the art. Diastereomeric resolution is performed and the pure enantiomers are recovered. Furthermore, the separation of enantiomers and diastereomers is usually accomplished by the use of chromatography using chiral stationary phases, optionally in combination with chemical derivatization methods (e.g. amines to amino groups formate). The compounds of the present invention may contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute the compounds. 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. "Optional" or "optionally" means that the subsequently described event or circumstance can but need not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
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.
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。When a substituent is vacant, it means that the substituent does not exist. For example, when X in A-X is vacant, it means that the structure is actually A. When the enumerated substituent does not indicate which atom it is connected to the substituted group, this substituent can be bonded through any atom, for example, pyridyl as a substituent can be connected to any atom on the pyridine ring. The carbon atom is attached to the group being substituted.
当所列举的连接基团没有指明其连接方向,其连接方向是任意的,例如,
中连接 基团L为-M-W-,此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成
也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成
所述连接基团、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 the linking group listed does not indicate its linking direction, its linking direction is arbitrary, for example, The connecting group L in the middle is -MW-, at this time -MW- can connect ring A and ring B in the same direction as the reading order from left to right to form It can also be formed by connecting loop A and loop B in the opposite direction to the reading order from left to right Combinations of the described linking groups, substituents and/or variations thereof are permissible only if such combinations result in stable compounds.
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
直形虚线键
或波浪线
表示。例如-OCH
3中的直形实线键表示通过该基团中的氧原子与其他基团相连;
中的直形虚线键表示通过该基团中的氮原子的两端与其他基团相连;
中的波浪线表示通过该苯基基团中的1和2位碳原子与其他基团相连;

这4种连接方式,即使-N-上画出了H原子,但是
仍包括
这种连接方式的基团,只是在连接1个化学键时,该位点的H会对应减少1个变成相应的一价哌啶基。
Unless otherwise specified, when a group has one or more linkable sites, any one or more sites of the group can be linked to other groups through chemical bonds. 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 Straight dotted key or tilde express. For example, the straight-shaped solid-line bond in -OCH3 indicates that it is connected to other groups through the oxygen atom in the group; The straight dotted line bond in indicates that the two ends of the nitrogen atom in the group are connected to other groups; The wavy lines in indicate that the 1 and 2 carbon atoms in the phenyl group are connected to other groups; Indicates that any connectable site on the piperidinyl group can be connected to other groups through a chemical bond, including at least These 4 connection methods, even if the H atom is drawn on -N-, but still include For groups with this connection method, only when a chemical bond is connected, the H at this site will be reduced by one to become the corresponding monovalent piperidinyl group.
