Definitions

  • the present application belongs to the field of medicine, and in particular to a tricyclic compound or a pharmaceutically acceptable salt thereof as an immunomodulator.
  • Tryptophan is an amino acid essential for the biosynthesis of proteins, niacin and neurotransmitter serotonin.
  • Indoleamine 2,3-dioxygenase also known as INDO or IDO
  • IDO IDO
  • IFN-y stimulation induces activation of IDO, leading to depletion of tryptophan, thereby preventing the growth of tryptophan-dependent cellular pathogens such as Toxoplasma gondii and Chlamydia trachomatis.
  • the activity of IDO also has anti-proliferative effects on many tumor cells. In the process of rejection of allogeneic tumors, IDO induction in vivo has been found, indicating that this enzyme may play a role in tumor rejection.
  • Small molecule inhibitors of IDO can be developed to treat or prevent IDO-related diseases.

定义和说明
在以下的说明中,包括某些具体的细节以对各个公开的实施方案提供全面的理解。然而,相关领域的技术人员会认识到,不采用一个或多个这些具体的细节,而采用其它方法、部件、材料等的情况下可实现实施方案。
除非本申请中另外要求,在整个说明书和其后的权利要求书中,词语“包括(comprise)”及其英文变体例如“包括(comprises)”和“包括(comprising)”应解释为开放式的、含括式的意义,即“包括但不限于”。
在整个本说明书中提到的“一个实施方案”或“实施方案”或“在另一实施方案中”或“在某些实施方案中”意指在至少一个实施方案中包括与该实施方案所述的相关的具体参考要素、结构或特征。因此,在整个说明书中不同位置出现的短语“在一个实施方案中”或“在实施方案中”或“在另一实施方案中”或“在某些实施方案中”不必全部指同一实施方案。此外,具体要素、结构或特征可以任何适当的方式在一个或多个实施方案中结合。
应当理解,在本申请说明书和附加的权利要求书中用到的单数形式的冠词“一”(对应于英文“a”、“an”和“the”)包括复数的对象,除非文中另外明确地规定。因此,例如提到的包括“催化剂”的反应包括一种催化剂,或两种或多种催化剂。还应当理解,术语“或”通常以其包括“和/或”的含义而使用,除非文中另外明确地规定。
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。
术语“任选”或“任选地”是指随后描述的事件或情况可能发生或可能不发生,该描述包括发生所述事件或情况和不发生所述事件或情况。例如,乙基“任选”被卤素取代,指乙基可以是未被取代的(CH2CH3)、单取代的(如CH2CH2F)、多取代的(如CHFCH2F、CH2CHF2等)或完全被取代的(CF2CF3)。本领域技术人员可理解,对于包含一个或多个取代基的任何基团,不会引入任何在空间上不可能存在和/或不能合成的取代或取代模式。
本文所用的Cm-n指该部分中具有m-n个碳原子。例如,“C3-10环烷基”指该环烷基具有3-10个碳原子。“C0-6亚烷基”指该亚烷基具有0-6个碳原子,当亚烷基具有0个碳原子时,该基团为键。容易理解,当含有杂原子时,m-n代表碳原子和杂原子数量的总和。
本文中的数字范围是指给定范围中的各个整数。例如“C1-10”是指该基团可具有1个碳原子、2个碳原子、3个碳原子、4个碳原子、5个碳原子、6个碳原子、7个碳原子、8个碳原子、9个碳原子或10个碳原子。

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。
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。当一个取代基的键可以交叉连接到一个环上的两个原子时,这种取代基可以与这个环上的任意原子相键合。当所列举的取代基中没有指明其通过哪一个原子连接到化学结构通式中包括但未具体提及的化合物时,这种取代基可以通过其任何原子相键合。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。例如,结构单元

实验例3:hIDO1体内药效测试
实验例3A模型验证:LPS诱导可使C57BL/6小鼠肺及血浆中的Kyn水平上升
体内实验中,可诱导炎症反应的化学介质如脂多糖(LPS)及干扰素γ(IFNg)被广泛应用以诱导IDO1的体内表达。为验证LPS的这一作用,执行此实验。实验前,将60mg/kg戊巴比妥钠注射入动物腹腔以麻醉动物。深度麻醉后,使用LPS(E.Coli O111:B4,Sigma-L2630)经鼻腔给药(i.n.)对6只C57BL/6小鼠(周龄6-8周,体重18-20g)进行诱导处理。LPS溶于PBS,剂量为25μg/20μL每只动物。作为对照,另6只小鼠经鼻腔接受了同体积PBS的处理。随后照常饲养,并分别于LPS/PBS诱导后的25、26和30小时收集血浆,于26和30小时(每时间点3只动物)收集肺样品并测定其中犬尿氨酸(Kyn)水平。Kyn水平的 测定由LC/MS方法完成,所用系统为Shimadzu LCMS-8050系统。
实验例3A结果如图1所示。此实验证实,经鼻腔给予的O111:B4大肠杆菌来源LPS可在给药后25-30小时内使C57BL/6小鼠肺及血浆中的Kyn水平升高。因此,经LPS诱导的C57BL/6小鼠模型是研究IDO1表达及活性的有效动物模型。
经LPS诱导后,C57BL/6小鼠肺及血浆中Kyn水平相对于经PBS处理的对照组有所升高。
实验例3B:
IDOi体内药效动力学:对LPS诱导后的C57BL/6小鼠肺及血浆Kyn水平的削减作用
实验例3A证实,经LPS诱导的C57BL/6小鼠是研究IDO1表达及活性的有效模型。在此模型上,实施例7和参照化合物(NLG919)的体内IDO1抑制活性进行了验证和比较。每组别6到10只,共3个组别的C57BL/6小鼠(周龄6-8周,体重18-20g)经剂量为25μg/20μL的O111:B4大肠杆菌LPS诱导。各组于诱导后0、12和24小时接受如下药物处理(给药体积均为5mL/kg):
组别1,口服40%聚乙二醇400(PEG400)水溶液作为溶剂对照;
组别2,口服50mg/kgNLG919,配制于40%PEG400水溶液;
组别3,口服50mg/kg的WXFL10310138,配制于40%PEG400水溶液。
并于最后一次给药结束后的1、2、4和6小时收集血浆,于2和6小时(每时间点3到5只动物)收集肺样品并使用LC/MS方法测定其中Kyn水平。
实验结果如图2,使用经LPS诱导的小鼠模型进行的体内药效动力学实验表明,实施例7与文NLG919均有效地抑制了IDO1的体内活性,并引起肺及血浆Kyn水平的下降。此外,相比于NLG919,实施例7所引起的Kyn水平下降程度更为显著。
实施例7相比NLG919更显著地降低了经LPS诱导的C57BL/6小鼠肺及血浆中的Kyn水平,本申请化合物对IDO1受体的抑制作用显著。
