本发明涉及用于治疗肺结核和相关疾病的药用组合物。
发明背景
每年高达九百万人感染肺结核,并且目前有五千万人感染对一线药物异烟肼和利福平都具有抗药性的结核杆菌(Mycobacteriumtuberculosis)(WHO,Fact sheet No.104,March 2007)。乙硫异烟胺(Ethionamide)(2-乙基硫异烟酰胺,2-乙基嘧啶-4-硫代甲酰胺(carbothioamide)),一种异烟肼的结构类似物,是目前治疗多种抗药性肺结核(MDR-TB)的最后防线药物。在其临床应用的35年间,乙硫异烟胺幸运地与异烟肼几乎未产生交叉抗药性,因为两种前体药物必须被不同的分支杆菌酶激活来产生其抗菌活性。乙硫异烟胺坚持以肝毒性剂量给药,由于EthR抑制ethA,即催化激活前体药物乙硫异烟胺变为抗分枝杆菌烟酰胺腺嘌呤二核苷酸衍生物的单加氧酶。血液中可接受的浓度要求最高至1g/日(Holdiness,M.R.,Clin Pharmacokinet1984,9,511-44),其与严重的副作用有关,包括神经毒性和致命的肝毒性。
WO 2008/003861描述在治疗肺结核和相关疾病中对乙硫异烟胺活性具有加强作用的化合物。本发明人发现2-苯乙基丁酸酯,一种批准的食物添加剂,和相关化合物能加强硫代酰胺或硫脲,例如乙硫异烟胺治疗肺结核的活性(WO 2009/080432)。

发明详述
本发明涉及一种药用组合物,其包含在下文中定义的式1化合物和式2化合物。本发明基于发现:抑制EthR与ethA启动子结合的化合物能大大增加乙硫异烟胺治疗肺结核的活性,但也能增加其它硫代酰胺或硫脲的活性。可使用哺乳动物细胞中的综合网络筛选能抑制EthR-VP 16结合其同源操纵基因部位(OethR-Phsp70min)并由此反式激活报告基因(SEAP)的表达的化合物。活性化合物从杂合启动子中除去EthR蛋白,由此进一步抑制报告基因SEAP的表达。该试验证明在识别活性化合物中非常精确,并且所测定的最小抑制浓度与ELISA筛选和微生物致病菌筛选的各自结果很好地一致。因此,哺乳动物综合筛选网络的结果证明与致病背景中观察到的内源性抗性调整网络高度相容(WO 2009/080432;Weber et al.,PNAS 2008,105,9994-8)。

将稳定表达pWW489和pWW491细胞系的无性系群体(Clonalpopulations)(Weber et al.,PNAS 2008,105,9994-8)用表1中显示的不同量的各化合物处理。加入化合物或溶剂(w/o)48小时后,分析含有分泌的报告基因SEAP的上清液。将未处理条件(w/o)下的SEAP水平设为100%。表1概括不同浓度的范围在500nMol(0.5)-300μMol(300)之间的各化合物存在下,SEAP表达反射的相对EthR-VP16活性。
在乙硫异烟胺的存在下,由于EthA-介导的该药物转化为一种抗分枝杆菌烟酰胺腺嘌呤二核苷酸衍生物,结核分枝杆菌(M.tuberculosis)的生长被明显破坏。EthR-介导的ethA转录的抑制需要相当高的临床剂量的乙硫异烟胺(高至1g/日,Holdiness,M.R.,ClinPharmacokinet 1984,9,511-44),这与严重的副作用相关,包括神经毒性和致命的肝毒性,然而这种高剂量经常尚不足以达到血流中的最小抑制水平。因此,2-苯乙基丁酸酯-触发的导致ethA去抑制作用的ethA启动子中EthR的分解能增加分枝杆菌对基于乙硫异烟胺疗法的敏感性。在亚抑制浓度的乙硫异烟胺(0.16和5μg/ml)存在下,该浓度很容易通过治疗剂量达到(cmax[250mg口服]=2μg/ml,t1/2=2h),结核分枝杆菌H37Rv的生长受0.5-40.5μMol的以下三个化合物的剂量依赖性抑制:2-(4-氟苯氧基)-1-(3-苯基吡咯烷-1-基)乙烷-1-酮(实施例15化合物),3-苯基-1-(3-苯基吡咯烷-1-基)丙烷-1-酮(实施例16化合物)和2-苯基-1-(3-苯基吡咯烷-1-基)乙烷-1-酮(实施例17化合物),参见表2。由于这三个化合物本身单用不显示任何生长抑制作用,这些化合物必须与乙硫异烟胺协同发挥杀灭病原菌的作用。

表2.乙硫异烟胺与实施例15、16和17化合物对结核分枝杆菌实验室菌株H37Rv生长抑制的协同作用
