Definitions
- the present invention relates to a series of benzo2-azaspiro[4.4]nonane compounds, in particular to a compound represented by formula (P) or a pharmaceutically acceptable salt thereof.
- Sphingosine-1-phosphate is a cell membrane-derived lysophospholipid signaling molecule, which mainly stimulates some members of the G protein-coupled receptor family to perform physiological functions, mainly sphingosine-1-phosphate Sphingosine-1-phosphate receptors (S1PRs) family.
- S1PR1 or EDG1 sphingosine-1-phosphate receptor 1
- S1PR2 or EDG5 sphingosine-1-phosphate receptor 2
- S1PR3 or EDG3 sphingosine-1-phosphate receptor 3
- S1PR4 or EDG6 sphingosine-1-phosphate receptor 4
- S1PR5 or EDG8 sphingosine-1 -Phosphate receptor 5
- Lymphocytes perceive the S1P concentration gradient through S1PR1, thereby regulating lymphocytes from the secondary lymphatic organs into the lymph and blood circulation.
- S1PR1 agonists can trigger S1PR1 endocytosis on the surface of lymphocytes, make lymphocytes unable to perceive S1P concentration gradients, prevent lymphocytes from migrating to lymph and blood circulation, trigger lymphocytes to homing, reduce the number of lymphocytes in the peripheral circulatory system, and prevent lymphocytes Reach the location of inflammatory damage or graft, reduce excessive inflammation, and have an immune regulation effect.
- Autoimmune disease refers to a class of diseases caused by the body's immune response to self-antigens, causing the immune system to erroneously attack its own tissues.
- S1PR1 agonists can effectively reduce excessive inflammation and can be used to treat or prevent autoimmune diseases, including multiple sclerosis, inflammatory bowel disease (divided into Crohn’s disease and ulcerative colitis), systemic lupus erythematosus and psoriasis Sickness etc.
- S1PR1 agonists are used to treat or prevent autoimmune diseases.
- Novartis' first-generation non-selective S1PRs agonist Fingolimod was approved by the FDA in September 2010 for relapsing multiple sclerosis (RMS)
- Novartis' second-generation selective S1PR1 and S1PR5 agonist Siponimod was also in 2019 In March, it was approved by the FDA for relapsing multiple sclerosis (RMS).

本发明涉及一系列苯并2-氮杂螺[4.4]壬烷类化合物,具体涉及式(P)所示化合物或其药学上可接受的盐。
鞘氨醇-1-磷酸(Sphingosine-1-phosphate,S1P)是细胞膜衍生的溶血磷脂信号分子,主要通过刺激部分G蛋白偶联受体家族成员发挥生理功能,主要是鞘氨醇-1-磷酸受体(Sphingosine-1-phosphate receptors,S1PRs)家族,目前,在哺乳动物中发现鉴定了五种不同的S1PR亚型,鞘氨醇-1-磷酸受体1(S1PR1或者EDG1),鞘氨醇-1-磷酸受体2(S1PR2或者EDG5),鞘氨醇-1-磷酸受体3(S1PR3或者EDG3),鞘氨醇-1-磷酸受体4(S1PR4或者EDG6),鞘氨醇-1-磷酸受体5(S1PR5或者EDG8)。S1PR1-3广泛表达于各种组织,S1PR4主要在淋巴系统和血液系统中表达,S1PR5主要在中枢神经系统中表达。淋巴细胞通过S1PR1感知S1P浓度梯度,从而调控淋巴细胞从次级淋巴器官进入淋巴和血液循环。S1PR1激动剂可以引发淋巴细胞表面S1PR1内吞,使淋巴细胞无法感知S1P浓度梯度,阻止淋巴细胞向淋巴和血液循环的迁移,引发淋巴细胞归巢,减少外周循环系统中淋巴细胞数量,阻止淋巴细胞达到炎性损害或移植物的位置,减少过度的炎症,具有免疫调控作用。
自身免疫疾病是指机体对自身抗原发生免疫反应,使免疫系统错误的攻击自身组织所导致的一类疾病的统称,目前确切定义的超过80种,过度的炎症反应是共有的特征。S1PR1激动剂可以有效减少过度炎症,可用于治疗或预防自身免疫性疾病,包括多发性硬化症,炎症性肠病(分为克罗恩病和溃疡性结肠炎),系统性红斑狼疮和银屑病等。
目前S1PR1激动剂的体内药效研究用于治疗或预防自身免疫性疾病。诺华公司第一代非选择性的S1PRs激动剂Fingolimod在2010年9月被FDA批准用于复发型多发性硬化(RMS),诺华公司第二代选择性的S1PR1和S1PR5激动剂Siponimod也在2019年3月被FDA批准用于复发型多发性硬化(RMS)。发现和应用新型S1PR激动剂具有广阔的前景。

相关定义
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。
这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物 与化学计量的适当的碱或酸反应来制备。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
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。
术语“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。
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。
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。
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。
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。
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;
表示该哌啶基上的任意可连接位点可以通过1个化学键与其他基团相连,至少包括
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,该位点的的H会对应减少1个变成相应的一价哌啶基。
