技术领域
本发明属于药物制剂领域,具体涉及一种抗病毒药物组合物及其制备方法和应用。
背景技术

虽然该类化合物在体外的抗病毒活性较好,但水中溶解度低,小于1mg/ml,且在溶液中稳定性低,成药性较差。该类化合物的水难溶性,在微观上,使其无法以分子状态透过生物膜,分散于水溶性的循环系统,作用于生物靶细胞,导致生物利用度低;在宏观上,增加了口服、粘膜途径、注射途径给药的难度。此外,该类化合物在水中搅拌溶解速度也很慢,长时间搅拌不仅耗时,对产品的微生物限度及稳定性也不利。
因此,本领域亟需针对式I所示的化合物的结构特点,解决该类化合物稳定性较差和成药性较差的问题,开发一种存储稳定性高,生物利用度高、使用方便的制剂,为防治冠状病毒,尤其是新型冠状病毒等病毒提供高效和安全的3CL蛋白酶抑制剂药物。

上述结果表明,本发明制备得到的制剂以上资料指标均满足冻干制剂常规要求。且上述制剂在40±2℃,75%±5%RH加速条件放置6个月,25±2℃,60%±5%RH下放置6个月,其含量无显著变化,有关物质无明显增长,这提示本发明的制剂具有非常优异的存储稳定性。
实施例9-11
对于羟丙基-β-环糊精溶液制剂,考察了不同pH(5.0,7.4,9.0)下溶液在25℃/60%RH,40℃/75%RH放置3天稳定性,配方如下表5:

根据与实施例1基本相同的方法,制备了20%(w/v)羟丙基-β-环糊溶液制剂,考察了不同pH(5.0、7.4、9.0)(分别对应实施例9-11)下,该制剂在25℃/60%RH、40℃/75%RH 放置3天的稳定性,其结果如下表6(仅列出有较大变化的杂质):

从上表6的结果看出,pH5.0相较于pH 7.4和pH 9.0下的制剂稳定性更好。
实施例12-16
基于上述HP-β-CD溶液制剂的稳定性结果可知,溶液的pH值对其稳定性有较大影响,其在pH7.4及9.0溶液制剂稳定性较差,而在pH5.0时相对稳定。因此,分两次进一步细化考察溶液在pH 4.5、5.0、5.5、6.0、6.5下溶液在25℃/60%RH、40℃/75%RH的稳定性情况,样品配方如下表7,结果如表8-9:

备注:由于两次试验使用的原料批次不同,故杂质数据有差异。
从上述表8-9的结果看出,不同pH值的羟丙基β环糊精溶液制剂在25℃/60%RH,40℃/75%RH条件下,制剂稳定性均良好。
对比例1
取DC402234适量,分别用HS-15(15-羟基硬脂酸聚乙二醇酯),吐温20,吐温80,泊洛沙姆188作为助溶剂,以提高产品的水溶解度,结果如表10:
表10 DC402234在不同溶剂中室温下的溶解度
介质 溶解度(mg/mL)
HS 15(15-羟基硬脂酸聚乙二醇酯)-水溶液(20:80) 18.23
Tween 20-水溶液(1:99) 2.31
Tween 80-水溶液(1:99) 2.73
泊洛沙姆188-水溶液(1:99) 0.21
从上述表10可以看出,在各助溶剂的临床允许浓度下,吐温20,吐温80,泊洛沙姆188作为增溶剂对DC402234均没有明显的增溶作用,无法满足制剂工艺对溶解度的要求,而HS15-水溶液可以显著提高溶解度;但由于DC402234在溶液中的稳定性较差(见表11),需要制备成固体才能确保产品的存储和使用稳定性。
对比例2-6
使用与实施例1基本相同的方法,采用HS15作为助溶剂按表11处方配制溶液:
表11
成分 对比例2 对比例3 对比例4 对比例5 对比例6
DC402234(mg/ml) 4.0 4.0 5.0 5.0 5.0
HS15(mg/ml) 70.0 70.0 70.0 70.0 70.0

氢氧化钠调pH 5.0 6.0 7.0 6.0 6.0
EDTA(w/v) -- -- -- -- 0.02%
将对比例2-6制得产品溶液,分别在40±2℃/75%±5%RH、25±2℃,60%±5%RH条件下放置,进行稳定性考察纯度、含量及杂质变化情况,结果如表12。
表12
Figure PCTCN2022100396-appb-000019
1总杂质计算方法为峰面积归一化法,采用100%扣除主峰峰面积占比即得。
表12的结果表明:25℃/60%RH、40℃/75%RH及2-8℃条件下放置6天,溶液均有较多杂质降解,总杂质含量增加明显,随着温度的升高降解更加明显,说明采用HS15作为助溶剂制得产品的稳定性,远远不如本发明的使用β-环糊精及其衍生物作为助溶剂得到的制剂的技术方案。
二.吸入制剂
将本发明的制剂作为吸入制剂通过吸入给药,并检测雾化特性及用药效果。
2.1处方组成如表13:

Flow Rate[L/min] 15
2.2.2递送速率和递送总量
溶液配制:取本品1支,3ml氯化钠注射液复溶后全部转移至雾化杯中。连接雾化杯呼出装置与滤膜装置,将呼吸模拟器设定为成人模式。开启呼吸模拟器并将其工作时间设定为60s,在呼吸循环的起始时启动雾化泵。60s结束后,关闭雾化泵,取出滤膜并在过滤装置中放置一张新的滤膜。重新设定呼吸模拟器工作时间为24min/14min,在呼吸循环的起始时启动雾化泵,24min/14min结束后,关闭雾化泵,取出滤膜。将两张滤膜及呼出装置中滤膜分别放入烧杯中,加入适量稀释剂,超声10min,收集洗液至50ml量瓶中,再加入适量稀释剂超声10min,收集洗液至同一量瓶中,加入稀释剂至刻度,摇匀,平行配制两份。试验结果见表15。
表15 样品递送速率和递送总量结果汇总
参数 10mg/ml
递送速率(mg/min) 1.52
递送总量(mg) 12.85
收集样品总量(mg) 27.1
结论:从表14-15的试验结果可以看出,在吸入给药过程中,药物的微细粒子剂量、递送速率和递送总量分布均匀稳定,递送效率高。
2.3 SD大鼠单次吸入给药的DC402234组织分布试验
SD大鼠(3只/组)单次经吸入给药给予0.47mg/kg上述DC402234雾化吸入制剂,检测不同时间点的肺部药物浓度及血浆药物浓度,结果如表16所示。
表16 SD大鼠吸入给药后各组织中DC402234的浓度和AUC
Figure PCTCN2022100396-appb-000020
从上述表16的结果可以看出,不同时间点,肺部药物浓度达到血浆药物浓度的16-1014倍,而肺部AUC达到血浆AUC的57倍;从而表明,经雾化吸入给药,DC402234在肺部的暴露量远远高于血浆的药物暴露量。冠状病毒主要经呼吸道传播,主要靶器官在肺部,而DC402234经吸入给药在肺部的药物暴露优势有利于其发挥治疗作用;雾化吸入制剂更高的肺部药物暴露量能够发挥更好的治疗效果,且雾化吸入制剂可以更方便地适用于门诊非住院患者等不同的患者人群和临床应用场景。
三.皮下制剂
3.1皮下制剂处方如表17:
表17
成分 用量
DC402234 200mg
羟丙基-β-环糊精 200mg-400mg
磷酸二氢钠 9.6mg
氢氧化钠 调节水相pH至4.5-6.0
叔丁醇(增溶剂) 2ml-2.4ml
注射用水 加至4ml(冷冻干燥过程去除)
3.2按上述表17配制皮下制剂,具体通用制备方法如下:
(1)将适量的羟丙基-β-环糊精、磷酸二氢钠溶解在部分注射用水中,并调节pH值;
(2)加入处方量的叔丁醇作为增溶剂搅拌均匀;
(3)再加入DC402234(式III化合物)并搅拌溶解;
(4)加入剩余的注射用水至最终体积,将溶液继续搅拌至混合均匀;
(5)将上述的溶液通过0.45微米(得中间体溶液)及0.22微米过滤器两级过滤除菌;和
(6)将溶液进行冷冻干燥。
由于本发明的主药式III化合物在水中的溶解性差,开发成皮下制剂时,需考虑溶解情况、复溶溶剂体积(不超过2ml),辅料安全用量,及稳定性的问题,需要设计合适的主药式III化合物与环糊精比例,既能够确保主药的完全溶解,又要满足复溶体积(不超过2ml)和良好的皮下注射生物利用度。
预期实际临床应用中,对于本发明的式III化合物,皮下制剂的优选规格为40-200mg/剂。
但当环糊精量减少时,式III化合物不能完全被包合,从而可能对制剂的溶解性和稳定性带来影响。因此,在降低HP-β-CD用量的基础上,要制备主药(式III化合物)载量高、存储稳定性好、复溶性能好的皮下制剂是非常困难。
3.3冻干前有机溶剂种类的确定
3.3.1冻干前溶剂
本发明选择下述有机药用溶剂作为冻干前溶剂,以尽量减少环糊精用量,考察溶剂对主药(以DC402234为例)和HP-β-CD的溶解能力,试验结果见表18、表19。
表18.不同溶剂对主药的溶解能力
Figure PCTCN2022100396-appb-000021
由上表可知,DC402234在水、乙腈中的溶解度低,二者不适于作为本品的冻干前溶剂。醇类溶剂对DC402234具有较好的溶解度,但本发明人在研究中发现,DC402234与醇类物质会发生反应,生成半缩醛,为了减少半缩醛的产生,综合考虑溶剂的毒性等,设计和选择了位阻更大的叔丁醇用于冻干前增溶剂,其溶解性数据如下述表19所示。
表19.叔丁醇对主药的溶解能力
Figure PCTCN2022100396-appb-000022
3.3.2叔丁醇浓度的筛选
采用叔丁醇作为增溶剂加入冻干前溶剂,进一步测试不同浓度的叔丁醇对产品质量及叔丁醇半缩醛的量产生影响。
溶液配制:配制pH5.0PBS溶液,分别加入不同体积的叔丁醇,配制浓度为50%、60%、75%的叔丁醇水溶液,再加入主药和HP-β-CD(主药:HP-β-CD重量比为1:1),配制主药浓度为50mg/ml的冻干前溶液;另外取叔丁醇,不加入水相,直接加入主药(无HP-β-CD),配制主药浓度为50mg/ml的冻干前100%叔丁醇溶液;再采用不加入PBS的60%叔丁醇溶液配制50mg/ml的冻干前溶液。将以上溶液进行冷冻干燥,分别考察冻干前溶液、冻干样品的有关物质(采用了HPLC液相色谱方法,反相C 18分析色谱柱,Na 2HPO 4-甲醇流动相体系(调节pH至9.0-10.0)梯度洗脱)和叔丁醇半缩醛(采用采用HPLC液相色谱法,反相C18分析色谱柱,甲醇-水流动相体系梯度洗脱,RRT为1.2)情况,并考察冻干样品的稳定性情况。稳定性试验结果见表20-23。

Figure PCTCN2022100396-appb-000025
Figure PCTCN2022100396-appb-000026
结论:叔丁醇浓度在50%-75%范围内,冻干前中间体溶液和冻干样品有关物质无明显差异;冻干样品在稳定性10天放置过程中,杂质E随温度升高而增加;其中不加HP-β-CD的100%叔丁醇冻干样品和未加PBS的60%叔丁醇冻干样品,杂质E的增加最明显。
进一步考察不同浓度叔丁醇中间体溶液和冻干样品中叔丁醇半缩醛的生成量,结果如表22:
表22.不同浓度的叔丁醇冻干样品中叔丁醇半缩醛稳定性检测结果
Figure PCTCN2022100396-appb-000027
由上述表22可知,叔丁醇浓度为50%-75%时,冻干后的样品叔丁醇半缩醛杂质的生成量较低且无明显差异,而100%叔丁醇和未加PBS的60%叔丁醇冻干样品叔丁醇半缩醛杂质生成量显著更多。
3.4主药与HP-β-CD比例对制剂稳定性的影响
3.4.1复溶溶剂对低HP-β-CD比例处方样品的溶解情况
以主药为200mg/剂的规格,采用加入叔丁醇的制备工艺,制备低HP-β-CD比例的冻干样品,考察不同浓度NMP对低HP-β-CD比例处方样品的溶解情况,试验结果见表23。
表23.低HP-β-CD比例样品的初步研究结果
Figure PCTCN2022100396-appb-000028
备注:溶解体积按照=350mg/NMP浓度。
由上述表23可以看出,低HP-β-CD比例的冻干样品,在NMP浓度为50-60%即可溶解澄清,且样品体积和NMP用量都符合要求。
3.4.2高HP-β-CD比例处方样品对制剂稳定性的影响
拟适当提高环糊精的比例,使部分主药被包合,从而达到减少叔丁醇用量的目的,结果如表24(规格:200mg)。
表24.高HP-β-CD比例处方样品的复溶研究
Figure PCTCN2022100396-appb-000029
从表24可以看出,随着HP-β-CD用量的增加,可减少冻干前叔丁醇用量,在复溶时,溶解样品的NMP浓度也可降低,但要完全复溶,复溶溶剂要么存在NMP超量(350mg/日),要么存在超过皮下给药体积限度(2mL)。
3.4.3不同HP-β-CD用量冻干样品的稳定性
上述实验初步确定,当主药为200mg/剂的规格时,NMP采用50-60%浓度时,主药与HP-β-CD质量比最多为1:2。设计试验,考察不同HP-β-CD用量冻干样品的初步稳定性情况。
溶液配制:配制60%叔丁醇的pH5.0的PBS水溶液,按照主药:HP-β-CD为1:0、1:1、1:2配制冻干前溶液。将以上样品进行冷冻干燥,考察不同HP-β-CD用量中间体溶液和冻干样品的有关物质和叔丁醇半缩醛情况,并考察冻干样品的初步稳定性情况。试验结果见表25。

Figure PCTCN2022100396-appb-000032
结论:主药:HP-β-CD为1:0-1:2范围内,中间溶液、冻干样品有关物质无明显差异;冻干样品放置10天,杂质E随温度升高而增加;随着HP-β-CD用量增加,在相同条件下杂质E减少,其他有关物质无明显差异。

从上述表27可以看出,主药:HP-β-CD为1:0-1:2之间时,叔丁醇半缩的生成量始终保持在较低的水平。
3.5.冻干前中间体溶液pH对产品质量的影响
冻干前中间体溶液pH不同,产品的质量可能会有差异。
溶液制备:分别配制pH4.5、pH5.0、pH5.5和pH6.0的PBS溶液,加入HP-β-CD(主药:HP-β-CD重量比为1:1),再加入适量叔丁醇,配制成60%叔丁醇的HP-β-CD水溶液,最后加入主药,得不同pH的冻干前中间体溶液;另外配制不加入PBS的HP-β-CD水溶液,再加入适量叔丁醇,配制成60%叔丁醇溶液,最后加入主药,得不加入PBS的冻干前溶液。将以上溶液分装后,进行冷冻干燥,考察不同pH对冻干前、后的有关物质和叔丁醇半缩醛影响,并考察冻干样品的初步稳定性。试验结果见表28-29。

结论:不同pH冻干样品放置在相同稳定性条件下,有关物质无明显差异。
3.6 Beagle犬皮下注射DC402234生物利用度试验
Beagle犬(2只/组)单次静脉注射10mg/kg(按DC402234计)注射用DC402234(用生理盐水复溶为2.5mg/ml的DC402234,50mg/ml的HPβCD)、单次皮下注射10mg/kg DC402234注射液1(50%NMP,100mg/ml DC402234,200mg/ml HPβCD)或DC402234注射液2(50%NMP,100mg/ml DC402234,100mg/ml HPβCD)后,血浆DC402234药动学参数及DC402234皮下制剂经皮下注射的生物利用度见表30。
