Abstract

一种用于抗病毒感染治疗的包含9-[(R)-2-[[(S)-[[[1-(异丙氧基羰基)-1-甲基]乙基]氨基]苯氧基氧膦基]甲氧基]丙基]腺嘌呤的药物组合物及其制备方法和用途。该药物组合物具有稳定性好、流动性好和溶出度高等优点,且在制剂生产过程中无粘冲现象。

Description

一种用于抗病毒感染的药物组合物及制备方法 技术领域
本发明属于药物制剂领域,特别涉及一种抗病毒感染药物组合物及其制备方法。
背景技术
乙型肝炎病毒(hepatitis B virus)是指引起人类急性肝炎和慢性肝炎的DNA病毒,简称HBV。由于HBV感染直接导致人类严重的肝脏疾病,包括肝硬化和肝细胞癌,因此,乙型肝炎是人类健康的一大威胁。乙型肝炎病毒DNA(脱氧核糖核酸),是乙肝病毒的核心物质和病毒复制的基础,核苷类化合物可通过直接竞争性地与天然脱氧核糖底物相结合而抑制病毒聚合酶,及通过***DNA中终止DNA链,因此核苷类化合物是治疗乙型肝炎的主要药物,其中包括,西多福韦、阿德福韦、拉米夫定以及替诺福韦(tenofovir)等。替诺福韦是一种新型核苷酸类逆转录酶抑制剂,可有效对抗多种病毒,用于治疗病毒感染性疾病。由于替诺福韦在生理pH条件下为双负离子的膦酸基团,故替诺福韦不易透过细胞膜吸收,生物利用度很低,并且还存在剂量依赖性肾毒性,限制了其治疗作用,因此必须通过酯化、成盐等手段制成膦酸酯前药才能用于临床。
许多制药公司正在进行研究和开发新一代替诺福韦前药,并已取得了一些成果,例如,WO0208241披露了一类用天然氨基酸(单取代)合成的替诺福韦磷酰胺酯前药(例如,GS-7340);WO2009105513公开了一类新型替诺福韦磷酸双酰胺前药,此类新型前药增加了血浆中的稳定性,增加了外周血单核细胞(PBMCs)中活性代谢物替诺福韦的累积浓度,提高了治疗效果;WO2014032481则公开了一类利用双取代氨基酸合成的一系列替诺福韦磷酰胺酯前药(例如,9-[(R)-2-[[(S)-[[[1-(异丙氧基羰基)-1-甲基]乙基]氨基]苯氧基氧膦基]甲氧基]丙基]腺嘌呤),该类前药半衰期比替诺福韦(TDF)明显延长,只需要不到替诺福韦(TDF)1/10剂量即可达到同样的抗病毒疗效,而且大大降低了药物对肾脏毒性,可显著改善患者的骨骼、肾脏实验室参数,ALT水平恢复正常的患者比例更高,是一类疗效高、毒副作用小的新型替诺福韦前药。
9-[(R)-2-[[(S)-[[[1-(异丙氧基羰基)-1-甲基]乙基]氨基]苯氧基氧膦基]甲氧基]丙基]腺嘌呤,水溶性较好,制成固体制剂后口服可被胃肠道迅速吸收,但该化合物对湿、热、酸、碱均不稳定,在高温、潮湿、酸、碱的条件下容易产生降解杂质A和杂质B,杂质降解程度越高对临床安全性的影响就越大,因此在制剂过程中应尽量避免使用高温、水 以及酸性或碱性的辅料。
Figure PCTCN2019113280-appb-000001
而且9-[(R)-2-[[(S)-[[[1-(异丙氧基羰基)-1-甲基]乙基]氨基]苯氧基氧膦基]甲氧基]丙基]腺嘌呤及其盐还具有流动性差、粘性强、原辅料相容性差的特点,在制剂实际操作过程中存在严重的粘滚轮现象,生产顺应性极差,这使得9-[(R)-2-[[(S)-[[[1-(异丙氧基羰基)-1-甲基]乙基]氨基]苯氧基氧膦基]甲氧基]丙基]腺嘌呤固体口服制剂的配制非常困难。
因此寻找一种质量稳定、流动性好、溶出度好、适合临床应用的9-[(R)-2-[[(S)-[[[1-(异丙氧基羰基)-1-甲基]乙基]氨基]苯氧基氧膦基]甲氧基]丙基]腺嘌呤固体口服制剂,是目前迫切需要解决的技术问题。

称取相应的原辅料,充分混合。
休止角测定:采用固定漏斗法测定,将表面皿放在漏斗正下方,调整表面皿使其原点与漏斗成垂直线,将物料从漏斗缓缓加入,一直加到表面皿的边缘盛不下物料,即成规则的圆锥体为止,测定漏斗高度的位置,测定圆锥底部直径,算出休止角,休止角≤40满足生产过程中对物料流动性的需求。
表4
Figure PCTCN2019113280-appb-000007
溶出度测定:取本品,按照《中国药典》2015年版四部通则“0931溶出度与释放度测定法”第二法,以pH4.5醋酸缓冲液900mL为溶出介质,转速50rpm,依法操作,取样测定溶出度,具体结果见表5。
将总混后的物料按照理论片重进行压片。
pH4.5醋酸缓冲液配制:称量108.4g无水醋酸钠、量取98ml醋酸加水至10L,即得。
