  • Treatment of related diseases caused by mycobacterial infection, such as Mycobacterium tuberculosis, is particularly suitable for diseases caused by drug resistance combined with mycobacteria.
  • Mycobacterium tuberculosis is the causative agent of tuberculosis. As a globally widespread and fatal infectious disease, according to the World Health Organization, more than 8 million people are infected each year and 2 million die from tuberculosis. In the past decade, tuberculosis cases have grown at a rate of 20% worldwide, especially in poor areas. If this trend continues, tuberculosis cases are likely to continue to grow at a 41% increase over the next two decades. In the 50 years since the initial application of chemotherapy, tuberculosis has been the leading infection to adults, second only to AIDS. Complications of tuberculosis have led to the emergence of many drug-resistant strains and a symbiotic relationship with AIDS.
  • the current treatment of tuberculosis uses a combination of multiple agents recommended by the US Department of Public Health, including the first use of isoniazid, rifampicin, pyrazinamide and ethambutol for two months, and then separately Haze and rifampin are combined for four months.
  • the use of this combination of drugs needs to be extended to seven months.
  • the drug combination also needs to add the remaining second-line agents, such as streptomycin, kanamycin, amikacin, capreomycin, ethionamide, cycloserine, cyclopropane Sand star and ofloxacin.
  • Such combination therapies for patients with multidrug-resistant tuberculosis usually have lower activity and higher side effects compared to current first-line drugs on the market.
  • TBA-354 is a nitroimidazolium derivative derived from PA-824. The mechanism of action of Delamanid is to inhibit the synthesis of methoxy and keto-mycolic acid, thereby killing bacteria, which are important components of the cell wall of Mycobacterium tuberculosis.
  • Nitroimidazole derivatives and treatments for Mycobacterium tuberculosis have been previously reported in large numbers (US 5,668,127, US 6,087,358; Jiricek et al., WO 2007075872 A2; Tsubochi et al., WO 2005042542 A1 and WO 2004033463 Al; JP 2005330266 A; THOMPSON et Al., WO 2011014776; MUSONDA et al., WO 2013072903).
  • Delamanid is a nitro-dihydroimidazolidinazole derivative that inhibits the biosynthesis of mycolic acid and exhibits high activity against MDR-TB in both in vitro and in vivo, November 2013.
  • Deltyba (Delamanid) was conditionally approved by the European Committee for the Use of Medicine (CHMP), and a 50 mg film-coated tablet was used for the treatment of MDR-TB. It was officially launched in Europe on April 28, 2014. Deltyba was identified as an orphan drug on February 1, 2008.
  • the present invention is directed to the invention of a novel nitroimidazole compound for use in the treatment of tuberculosis and multidrug-resistant tuberculosis.
  • OPC-67683 has been proven to be clinically effective in the treatment of multidrug-resistant tuberculosis, there is room for further optimization in the course of treatment and cure. Based on this, the present invention designs a series of nitroimidazole derivatives. They have been shown to have better water solubility and pharmacokinetic properties. It is expected that this improvement will lead to better clinical performance.

抗肺结核病的硝基咪唑衍生物
相关申请的交叉引用
本申请主张如下优先权:中国专利申请CN201711434015.9,申请日2017年12月26日。
技术领域
本发明涉及一种取代硝基咪唑类衍生物,具体公开了式(I)所示化合物、其药学上可接受的盐或其立体异构体,包含上述化合物的药物组合物,以及它们用于治疗由分支杆菌感染引起的相关疾病,如结核分枝杆菌,尤其适用于耐药性结合分支杆菌引起的疾病。
背景技术
结核分枝杆菌是结核病的病原体。作为一种广布全球,且可致命的感染性疾病,据世界卫生组织统计,每年约有超过800万人感染,200万人死于结核病。在过去十年,结核病病例在世界范围内以20%的速度增长,该涨幅在贫困地区尤其显著。如果该趋势照此发展下去,结核病病例在未来二十年极有可能以41%的涨幅继续增长。在最初应用化疗方法之后的五十年内,结核病一直都是仅次于艾滋病的,致成年人死亡的主要感染病。结核病的并发症引发了许多耐药菌株的出现,同时与艾滋病达成共生关系。艾滋病病毒测试呈阳性,且同时感染结核病的人群,比起艾滋病病病毒测试呈阴性人群有多出30倍几率发展成激活的结核病。平均来讲,每三个死于艾滋病的病人中,就有一人是结核病导致的。
结核病的现有治疗应用了美国公共卫生署推荐的多种药剂的组合的配方,包括首先使用异烟肼,利福平,吡嗪酰胺和乙胺丁醇组合两个月,然后再单独使用异烟肼和利福平组合四个月。对于感染了艾滋病的患者,该种药物组合的使用需延期至七个月。对于感染了耐多药结核病的患者,该药物组合还需添加其余二线药剂,如链霉素,卡那霉素,阿米卡星,卷曲霉素,乙硫异烟胺,环丝氨酸,环丙沙星和氧氟沙星。此类用于耐多药结核病(通常疗程超过2年)的患者的组合治疗药物,通常具有更低的活性,和更高的副作用相比于目前市面上的一线药物。
因此,迫切的需要此类新型的无论是对有氧(活跃的)还是厌氧(潜伏期或顽固的)环境均具有高活性的硝基咪唑并噁唑衍生物,作为抗结核菌药物。显然,既能缩短治疗时间,又可减少监督频率的药物可以带来最大的益处。
当前,Otsuka新型产品Deltyba(delamanid)已经上市,作为耐多药结核病治疗的一种联合药物,被批准用于成人的治疗,鉴于耐药和耐受方面的考量。同样,硝基咪唑噁嗪类化合物PA-824和TBA-354(J.Med.Chem.53;8421-8439(2010))在抑制结核分支杆菌方面显示出较好的体外和体内活性。PA-824的作用机理涉及一氧化氮气体的释放(Singh et al.,Science 322;1392-1395(2008)),以及细菌的6-磷酸葡萄糖磷酸脱氢酶(FGD1)和辅因子(F420)介入的还原步骤(Stover et al.,Nature 405;962-966(2000))。基因芯片技术对野生型诱变菌株与FGD1和F420的研究发现了一个由151个氨基酸(17.37kDa)组成的未知功能的蛋白,(Rv3547)似乎对这一系列的还原步骤起主导作用,后来通过研究FA-824的还原亦印证了此假设。TBA-354是由PA-824发展而来的硝基咪唑噁嗪类衍生物。Delamanid的作用机理是抑制甲氧基和酮基分支菌酸的合成,从而杀死细菌,他们均是结核杆菌细胞壁的重要组成部分。硝基咪唑类衍生物以及用于结核杆菌的治疗在先前已经被大量报道(US 5,668,127、US 6,087,358;Jiricek et al.,WO 2007075872A2;Tsubochi et al.,WO 2005042542A1以及WO 2004033463Al;JP 2005330266A;THOMPSON et al.,WO 2011014776; MUSONDA et al.,WO 2013072903)。
在所有抗结核杆菌的临床研发药物中,硝基咪唑类衍生物走得越来越靠前,越来越具有吸引力。从上面的专利申请可以看出,用于结核病治疗,特别是对耐多药结核病治疗的主要专利通式如下(1和2)所示:
Figure PCTCN2018123377-appb-000001
通过研究,用于治疗结核病的两个新的活性分子OPC-67683(delamanid,WO 2004035547A1)和TBA-354(WO 2011014774A1)结构如下(3和4)所示:
Figure PCTCN2018123377-appb-000002
Delamanid是硝基-二氢咪唑并噁唑类衍生物,主要通过抑制霉菌酸的生物合成发生作用,对耐多药结核杆菌无论是在体外还是体内均表现出很高的活性,2013年11月21日,被欧洲人用药品委员会(CHMP)有条件批准Deltyba(Delamanid),50毫克的薄膜包衣片用于耐多药结核杆菌的治疗。于2014年4月28日正式在欧洲上市。Deltyba在2008年的2月1日被认定为孤儿药。本发明致力于发明一种新型硝基咪唑类化合物,用于结核病以及耐多药结核病的治疗。
虽然OPC-67683被证明在临床上对耐多药结核病治疗具有一定的疗效,但在疗程及治愈率上有更进一步优化的空间,基于此,本发明设计了一系列的硝基咪唑类衍生物,它们被证实具有更优秀的水溶性及药代动力学性质。期望此改进能带来更好的临床表现。

术语“赋形剂”通常是指配制有效的药物组合物所需要载体、稀释剂和/或介质。
针对药物或药理学活性剂而言,术语“有效量”或“治疗有效量”是指无毒的但能达到预期效果的药物或药剂的足够用量。对于本发明中的口服剂型,组合物中一种活性物质的“有效量”是指与该组合物中另一种活性物质联用时为了达到预期效果所需要的用量。有效量的确定因人而异,取决于受体的年龄和一般情况,也取决于具体的活性物质,个案中合适的有效量可以由本领域技术人员根据常规试验确定。
术语“活性成分”、“治疗剂”,“活性物质”或“活性剂”是指一种化学实体,它可以有效地治疗目标紊乱、疾病或病症。
“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,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,
Figure PCTCN2018123377-appb-000048
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
Figure PCTCN2018123377-appb-000049
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
Figure PCTCN2018123377-appb-000050

1.动力学溶解度测试:称量定量化合物样品溶解在纯DMSO中,终浓度为10mM。将受试化合物与对照化合物(10mM DMSO母液,每孔10μL)加入含有每孔490μL缓冲液的96孔板中。涡旋2分钟后,样品板在振荡器上室温下(22±2℃)孵育24小时。然后转移200μL样品到MultiScreen过滤板(聚碳酸酯膜),以微孔真空歧管(millipore vacuμm manifold)过滤并收集滤液。以HPLC-UV测定滤液中化合物的浓度。3个不同浓度的UV标准品溶液与溶解度测试样品先后进样。每个样品进针2次,带入标曲计算浓度,求平均值。
2.MDR1-MDCK细胞双向渗透性评估实验:将永久性表达人P-糖蛋白(P-glycoprotein)的MDR1-MDCK细胞种植在96孔Insert细胞板(细胞培养嵌套板),培养4-7天后形成汇聚的单层细胞;利用评估fenoterol(低渗透性标记物)与propranolol(高渗透性标记物)的单向(A→B)渗透性,以及Digoxin(一种P-糖蛋白底物)的双向渗透性来验证单层细胞的质量。这三个对照化合物做两个复孔。
待测化合物转运实验的标准条件如下:
-测试浓度:2μM(DMSO≤1%);
-重复:n=3;
-方向:双向转运,包括A→B和B→A两个方向;
-孵育时间:单个时间点,2.5小时;
-转运缓冲液:HBSS,pH7.4;
-孵育条件:37℃,5%CO 2,95%相对湿度。
孵育结束后,取给药孔(donor wells)和接收孔(receiver wells)内的样品溶液立即与含有内标的冷乙腈溶液混合。并用含有内标的冷乙腈溶液裂解细胞来测量细胞内化合物的聚积量。采用LC/MS/MS方法分析待测化合物在所有样品(包括起始给药液,给药孔上清液,接收液,细胞裂解液)中的浓度。待测化合物的浓度用其峰面积与内标峰面积之比来表示。表2列出了本发明部分化合物的体外动力学溶解度(Kinetic Solubility,KS)以及在MDR1-MDCK单层细胞中的渗透性数据。显然,这两个化合物在KS和渗透性上都优于OPC-67683。

第四部分:体内药代动力学
以标准方案测试化合物静脉注射及口服给药后的啮齿类动物药代特征。具体来说,实验中待测化合物静脉注射及口服给药7到10周龄的CD-1雄性小鼠。口服制剂为0.5%的甲基纤维配成的混悬液;静脉注射制剂是乙醇/DMSO/聚乙二醇400/纯水(10/10/50/30)配成的澄清溶液。收集血浆与肺的样品,以LC-MS/MS方法分析,并计算药代参数。化合物4A的药代参数见表3,很明显,化合物4A药代参数均优于参考化合物(OPC-67683),值得注意的是4A的肺部药物浓度在给药后1小时及6小时均远远高于参考化合物(OPC-67683),达到了参考化合物的3倍以上。对于肺部感染结核杆菌的患者,越高的药物暴露量意味着越好的药效,这一点是非常重要的。

第五部分:体内药效学
试验设计及方法:
实验原理为使用雾化器产生带结核杆菌的气溶胶对小鼠进行气溶胶吸入感染,之后正常条件下饲养被 感染小鼠31天以形成结核杆菌慢性肺部感染,随后对小鼠进行口服方式的药物治疗。实验结束后计数小鼠肺部的载菌量以检测药物的杀菌疗效。
实验所使用的菌种为肺结核杆菌(Mycobacterium tuberculosis)Erdman,ATCC 35801。扩增培养基为以Middlebrook 7H9为基础的肉汤培养基,并添加终浓度为0.2%的甘油,0.05%的吐温80,和10%的OADC(oleic acid-albumin-dextrose-catalase)溶液。将细菌接种于扩增培养基,在37℃培养1-2个星期以达到对数生长期。之后在4℃使用3150g离心15分钟收集菌液。使用添加了0.05%吐温80的PBS洗涤收集的结核杆菌两次,然后使用8μm孔径的滤器过滤菌液以除去过大的菌块,均在4℃进行。将菌液以0.5ml为单位分装并储藏于-80℃超低温冰箱。所制菌液的实际浓度由在7H11平板上的菌落计数得到。
动物在动物饲养设施中适应性饲养至少两天。动物感染实验当天,将上一步所制菌液融化,使用Middlebrook 7H9稀释至OD600=0.1,此吸光度的肺结核杆菌菌液大约含0.5×10 6CFU/ml~1×10 6CFU/ml。取100μl此菌液涂板于7H11平板以测取菌液的实际CFU浓度,此菌液为接种液。
使用10ml细菌接种液在Middlebrook inhalation exposure system(IES)(Glas-Col,Terre Haure,IN,USA)中产生气溶胶对动物进行气溶胶吸入感染。感染前,预加热IES 15分钟,固定小鼠,加菌液至雾化器内,气溶胶暴露吸入感染1.5个小时。立即彻底灭菌IES,并且记录感染时间,为T0。
感染后第T3天和第T29天分别使用CO 2安乐死T3组和T29组的小鼠,对全肺的肺结核杆菌进行CFU计数:小鼠被CO 2安乐死后,取肺置于3ml HBSS(Hanks Balanced Salt Solution)缓冲液中匀浆20-30s,随后超声15秒。用相同的HBSS缓冲液以10倍梯度稀释匀浆液1:10至1:10000。使用6孔板制作7H11平板,每孔接种50μl匀浆液。所有6孔板于37℃培养18天后计数CFU。
容剂对照组以及治疗组于感染后第29天开始给药,直至第56天。一天后,第57天实验结束,小鼠被CO 2安乐死后对全肺的肺结核杆菌进行CFU计数。
试验结果:见表4。
