在已知的亲环素抑制剂中,可列举[D-MeAla]3-[EtVal]4-环孢霉素(也称作Debio 025-Debiopharm)以及NIM811([MeIle]4-环孢霉素-诺华(Novartis))。化合物Debio 025是环状十一肽且由Wenger等在WO00/01715中具体报道(CAS登记号254435-95-5)。化合物NIM811是环状十一肽且由Ko等在EP 0484281中具体报道。

在某些优选实施方案中,联合治疗中所需的活性成分可合并到单个药物组合物中以同时给药。
当述及组合物、载体、稀释剂和试剂时,本文使用的术语“药学上可接受的”和它们语法上的变化可相互交换使用且表示该物质可施用于哺乳动物而不会产生不良的生理效果例如恶心、头晕、心嘈等。
其中溶解或分散有活性成分的药物组合物的制备方法是现有技术中已知的,且不需要基于配方对其进行限定。通常这种组合物以液体溶液或混悬液制备成注射剂;然而,也可制备适于在使用前溶解或混悬在液体中的固体形式。制剂也可为乳化的。特别地,上述药物组合物可配置成固体剂型,例如胶囊、片剂、丸剂、粉剂、糖丸剂或颗粒剂。
通常根据活性化合物的溶解性和化学性质、给药的具体模式和药学实践中遵守的规定来确定赋形剂的选择和赋形剂中活性成分的含量。例如,赋形剂(如乳糖、柠檬酸钠、碳酸钙、磷酸二钙)和崩解剂(如淀粉、褐藻酸和某些复合硅酸盐)与润滑剂(如硬脂酸镁、十二烷基硫酸钠和滑石粉)结合可用于制备片剂。为了制备胶囊,使用乳糖和高分子量聚乙二醇是有利的。当采用水混悬液时,其可包含乳化剂或混悬促进剂。也可以使用稀释剂如蔗糖、乙醇、聚乙二醇、丙二醇、甘油和氯仿或其混合物。
上述药物组合物可以适合的剂型施用于人和动物,通过局部或全身给药,包括口服给药、直肠给药、鼻腔给药、口腔给药、眼部给药、舌下给药、透皮给药、直肠给药、局部给药、阴道给药、肠胃外给药(包括皮下记注射、动脉注射、肌肉注射、静脉注射、皮内注射、鞘内注射、硬膜外注射)、脑池内给药和腹腔给药。应当理解的是优选的途径可随着例如接受者的情况而变化。
配方可按照药剂领域公知的任何方法制备成单位剂量。这种方法包括使活性成分和由一种或多种助剂组成的载体相结合。通常上述配方通过将活性成分与液体载体或极细固体载体或两者均匀且密切地结合而制备,然后如果需要对产品成形。
以单次或多次剂量施用于对象的本发明的化合物的每日总剂量可为例如从约0.001至约100mg/Kg体重每天,且优选0.01至10mg/Kg/天。单位剂量组合物可包含上述量的约数从而可用于构成日剂量。然而可以理解的是,用于所有具体患者的具体剂量水平将依赖于很多因素包括体重、健康概况、性别、饮食、给药时间和途径、吸收和代谢率、与其它药物的组合以及治疗的具体疾病的严重性。

亲环素PPlase活性通过使用标准的胰凝乳蛋白酶偶联分析法(Kofron JL,Kuzmic P,Kishore V,Colón-Bonilla E,Rich DH.Determination of kinetic constants for peptidyl prolyl cis-trans isomerasesby an improved spectrophotometric assay.Biochemistry.1991Jun 25;30(25):6127-34)测定。将检测缓冲液(25mM Hepes,100mM NaCl,pH7.8)亲环素A、B或D(1900nM储存液)预冷至4℃,然后向其中加入5μL的50mg/ml胰凝乳蛋白酶在1mM HCl的溶液。通过加入20μL3.2mM的多肽底物(Suc-Ala-Ala-cis-Pro-Phe-pNA)在LiCl/TFE中的溶液并快速翻转启动反应。在开始混合一段时间后,追踪对硝基苯胺在390nM的吸光度直到反应完成(1分钟)。实验中LiCl的最终浓度为20mM。TFE以4%(V/V)浓度存在。使用分光光度计每1S收集吸光度读数。化合物的抑制实验按照上述相同的方式实施。向亲环素在检测缓冲液的溶液中加入5μL试样等分的化合物DMSO溶液。通过加入底物开始检测。在所有的测定中亲环素A用作对照。亲环素PPlase抑制活性百分数根据得到的斜率和数值计算,上述数值代表至少两个独立测定值的平均值。+/-SD的均值为<10%。
在复制子模型中评估抗病毒活性
将基因型1b双顺反子复制子转染(Krieger,N.,V.Lohman和RBartenschlager.2001.J.Virol.75:4614-4624)在补充有10%胎牛血清、50IU/ml青霉素、100μg/mL链霉素、0.1μg/mL两性霉素和600μg/mL遗存霉素(G418,Invitrogen)的Dulbecco’s改良的Eagle’s培养基Glutamax II(Invitrogen,Carlsbad,California)中培养的Huh7细胞中。
带有HCV复制子的细胞以每孔5000细胞的低密度在96-孔板上接种。上述细胞在包含10%胎牛血清和1%DMSO没有G418的Dulbecco改良的Eagle培养基上用浓度递增的测试化合物处理并培养3天。用RNeasy 96kit(Qiagen)提取总RNA。通过实时定量聚合酶链式反应检测测定HCV RNA水平,上述实时定量聚合酶链式反应检测在ABI 7003装置(Applied Biosystems,Foster City,California)上使用具有HCV-特异性引物(正义5′-CGCCCAAACCAGAATACGA-3′和反义5′-AGATAGTACACCCTTTTGCCAGATG-3′SEQ ID NO:1和SEQID NO:2)的探针(5′-6-FAM-CAATGTGTCAGTCGCG-TAMRA-3′SEQID NO:3)的Taqman技术进行。HCV RNA水平通过Nanodrop 1000分光光度计(Nanodrop Technologies,Wilmington,Delaware)测定。结果以GAPDH基因进行归一化。每个数据点表示细胞培养中的至少三次重复的平均值。通过比较化合物处理的细胞中的HCV RNA水平和用1%DMSO处理的对照细胞评估处理后HCV RNA水平减少量。
在细胞培养物中在JFH1感染模型中评估抗病毒活性
质粒pJFH1(包含JFH1HCV基因型2a分离群的全长cDNA和雷尼利亚萤光素酶基因)用于在Huh7细胞培养中产生感染性的HCV颗粒(HCVcc),如前所述(Wakita T,Pietschmann T,Kato T,Date T,Miyamoto M,Zhao Z,Murthy K,Habermann A,Krausslich HG,Mizokami M,Bartenschlager R,Liang TJ.Production of infectioushepatitis C virus in tissue culture from a cloned viral genome.Nat Med2005;11:791-6),Huh7细胞以30000-50000个细胞/孔的密度接种于24-孔板上,稍后用200μl HCVcc在37℃感染24h。培养完成后,移去上清液,用新的培养基清洗JFH1-感染的细胞。将浓度递增的测试化合物加入含有2%DMSO的培养基中,细胞在37℃培养。感染44h后,细胞用Dulbecco’s PBS(Invitrogen)清洗一次,向每孔中加入100μl Renilla裂解缓冲液(Promega,Madison,Wisconsin)。裂解产物在-80℃冷冻。解冻上述冷冻的样品用于在一批中读数,按照生产商(Promega)的规定20μl与萤光素酶检测底物混合。萤光素酶活性在光度计中测定10S。
化合物细胞毒性的评估
Huh7和HEK293细胞分别以每孔2000和1000细胞接种于96-孔微孔板在DMEM glutamax-II-10%FBS中。24小时后,加入连续稀释的化合物。细胞允许在37℃增殖3天。如前所述(Mosmann T.Rapidcolorimetric assay for cellular growth and survival:application toproliferation and cytotoxicity assays.J Immunol Methods 1983;65:55-63),然后用溴化3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑比色测定评估细胞存活力。
在小鼠中的急性毒性
在小鼠中评估F684的急性毒性。在该研究中,对雌性小鼠(n=3/组)施用阴性对照(PBS)或F684(根据体重,1mg/kg、10mg/kg、50mg/kg和150mg/kg溶于PBS中)一次性腹腔注射。当注射时,动物大约5个月大且体重为27到33g。所有的动物均存活至计划处死时。在施用F864或载体对照组的小鼠之间,没有观察到体重、食物摄入、临床观察或总体器官尸检方面的差别。这些结果显示F684无急性毒性。
