Abstract
CXCR2拮抗剂的一类化合物,以及在制备作为CXCR2拮抗剂的药物中的应用。具体涉及式(Ⅱ)所示化合物、其异构体或其药学上可接受的盐。
Description
本申请主张如下优先权:
CN201810027003.2,申请日2018.01.11。
本发明涉及作为CXCR2拮抗剂的一类化合物,以及在制备作为CXCR2拮抗剂的药物中的应用。具体涉及式(Ⅰ)所示化合物、其异构体或其药学上可接受的盐。
慢性阻塞性肺病(COPD)是一种使人衰弱的疾病,特征在于由慢性气道炎症引起的渐进气流受限。通常是由于吸入有害颗粒和气体引起,主要来自吸烟和空气污染。它的病状包括粘液分泌过多、气道变窄、纤维化以及肺泡的损耗。它可导致平均体重下降,骨质疏松,心血管疾病和心理损害。中度至重度慢性阻塞性肺病目前的治疗是相对无效的,没有可用的药物能够显著降低疾病恶化或死亡。慢性阻塞性肺病全球倡议组织(GOLD)建议对中度至重度COPD患者使用长效支气管扩张(LABA和LAMA)作为一线维持治疗。虽然这些药物产生有效的支气管扩张,但它们并不能治疗慢性阻塞性肺病患者的潜在炎症。吸入糖皮质激素(ICS)虽然对哮喘患者有一定效果,但对慢性阻塞性肺病在很大程度上是无效的。因此当支气管扩张剂对患者没效时,附加的治疗方法包括吸入糖皮质激素(ICS)只能被谨慎使用。
COPD是一种慢性炎症性疾病,这表明有效抗炎疗法是目前慢性阻塞性肺病领域中最大的未满足治疗需求。罗氟司特是一种口服磷酸二酯酶4(PDE4)抑制剂,这是治疗慢性阻塞性肺病第一个被批准的口服抗炎药。但罗氟司特被其很强的副作用限制了使用,因此有必要发展其他新型的抗炎靶标,用于治疗慢性阻塞性肺病。
白介素8(IL-8或CXCL8)是一种含72个氨基酸残基的蛋白,它是控制炎症位点白细胞招募和转移的关键因子。白介素8通过与其受体结合而发挥作用,它的受体是一种G-蛋白偶联受体,属于CXC趋化因子受体,包括CXCR1和CXCR2。CXCR2在人类中性粒细胞表面高表达,当白介素8与中性粒细胞表面的CXCR2结合后,会引起细胞内的一系列反应,包括钙流量改变,脱颗粒作用以及后续的趋化性。白介素8在多种炎症疾病中含量升高,如关节炎、哮喘、慢性阻塞性肺病等,预示着阻断它与其受体的相互作用,将会对这些疾病有益。
WO2007124424公开了CXCR2拮抗剂Danirixin在治疗相关疾病中的应用。

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“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,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。
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。
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。
除非另有规定,术语“杂”表示杂原子或杂原子团(即含有杂原子的原子团),包括碳(C)和氢(H)以外的原子以及含有这些杂原子的原子团,例如包括氧(O)、氮(N)、硫(S)、硅(Si)、锗(Ge)、铝(Al)、硼(B)、-O-、-S-、、-C(=O)O-、-C(=O)-、-C(=S)-、-S(=O)、-S(=O)
2-,以及任选被取代的-C(=O)N(H)-、-N(H)-、-C(=NH)-、-S(=O)

实验例4:化合物对PPE诱导的COPD模型治疗作用
实验目的:
测试化合物对PPE诱导的C57BL/6小鼠COPD模型治疗作用效果。
实验材料:
动物:C57BL/6小鼠(雌性,17.5-18.5g,6~8周龄)
药物:为猪胰腺弹性蛋白酶(PPE)(sigma,0.068U/μL);图1、2、3中化合物1为Danirixin;化合物2为WX006A。
分组:①COPD模型组(猪胰腺弹性蛋白酶造模组)
②PPE+Danirixin(40mpk)
③PPE+Danirixin(120mpk)
④PPE+WX006A(4mpk)
⑤PPE+WX006A(12mpk)
实验操作:
1.造模方式:舌后滴注PPE。
2.给药方式:以1%DMSO/1%羟丙基甲基纤维素/0.2%吐温80的水溶液为溶媒,给药体积为200μL/只灌胃给药,每天给药,共给药4周。
3.实验终点:第29天,处死小鼠,收集样本,进行流式检测。
流式检测
给药4周后取小鼠血液、肺泡灌洗液、肺组织测定炎性细胞百分比。
1)肺泡灌洗细胞:处死小鼠,进行颈部解剖,暴露气管进行气管插管插管。1mL 4℃遇冷硫酸盐缓冲液灌洗,灌洗3次,合并灌洗液。1200转/分钟离心5分钟,弃上清液,收集细胞悬液;
2)取小鼠血液、肺组织,血液裂红洗涤后制成细胞悬液;肺组织剪碎成小块再用I型胶原酶37℃消化1.5小时,经过滤、裂红和洗涤后制成细胞悬液;
3)计数并将细胞悬液分到流式管中。
4)分管后标记CD45、Ly6c、Ly6g、CD11b流式荧光抗体;
5)洗涤细胞后使用流式细胞仪检测中性粒和单核细胞占CD45
+细胞的百分比。
实验数据结果如图1、2、3所示,得到结论:在PPE诱导的小鼠COPD模型中,本发明化合物显著地抑制了肺组织中的中性粒细胞占比,优于阳性对照Danirixin。本发明化合物和Danirixin高剂量(120mpk)对肺泡灌洗液中中性粒细胞与单核细胞占比均有显著的降低作用,展现出对炎症良好的抑制作用。同时本发明化合物在低剂量(4mpk)也能达到相当的抗炎作用效果。
