本申请涉及但不限于医药技术领域,具体涉及但不限于一种三芳基二甲基哌嗪二盐酸盐的多晶型物及其制备方法和应用。
背景
抑郁症是一种常见的精神疾病,主要表现为情绪低落,兴趣减低,悲观,思维迟缓,缺乏主动性,自责自罪,饮食、睡眠差,担心自己患有各种疾病,感到全身多处不适,严重者可出现自杀念头和行为。美国精神病协会出版的“Diagnostic and Statistical Manual of Mental Disorders”《精神病诊断和统计手册》第四版中,抑郁症被归类到心境障碍下,分为三种类型:重度抑郁症、心境恶劣障碍和其它未指明的抑郁症。
引起抑郁症的因素包括:遗传因素、体质因素、中枢神经介质的功能及代谢异常、精神因素等。在治疗抑郁症的努力中,已发展了多种抗抑郁组合物,例如,色曲林、弗洛西汀、帕罗西汀、氟伏沙明、丁氨苯丙酮。这些药物虽然有效,却经常产生有问题的副作用,如嗜睡症、思维混乱、不能集中注意力和性功能障碍。并且,这些药物存在起效时间长的问题,需要约6至8周才能显示出任何期望的治疗效果。
发明概述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请发明人经大量实验研究发现,三芳基二甲基哌嗪化合物可从不同途径来增强阿片类受体在抗抑郁症中的作用,并因此基于阿片样受体δ-受体理论,根据抗抑郁活性δ-受体的特定位置,针对抑郁症的作用靶点δ-受体,开发出具有以下式I结构的δ-受体激动剂三芳基二甲基哌嗪化合物(4-((R)-((2S,5R)-4-(3-氟苄基)-(2,5-二甲基哌嗪-1-基)(3-羟基苯基)甲基)苯 基)(4-甲基哌啶-1-基)甲酮二盐酸盐(分子式:C33H42FCl2N3O2,分子量:602.69)及其多晶型物,并拟将其开发为具有抗抑郁功效以及其他潜在功效的新药成分。

稳定性试验
多晶型物B和O在动态水分吸附下均会转变为无定形。因此,以下仅考察多晶型物P、F和J在不同环境下的物理稳定性。
将多晶型物P、F和J分别置于以下四种不同环境的条件下,进行物理稳定性研究。
条件1:40℃/75%RH/一周
分别称取10mg至15mg的多晶型物P、F和J置于1.5mL的玻璃瓶内,在40℃、75%RH条件下的恒温恒湿箱中敞口放置一周,随后将多晶型物P、F和J进行XRPD测试,测定样品晶型是否变化。图11至13分别为多晶型物P、F和J在40℃、75%RH条件下放置一周前后的晶型物的XRPD对比图。
条件2:60℃干燥过夜
分别称取10mg至15mg的多晶型物P、F和J置于1.5mL的玻璃瓶内,在60℃条件下的恒温干燥箱中敞口放置过夜,随后将多晶型物P、F和J进行XRPD测试,测定样品晶型是否变化。图14至16分别为多晶型物P、F和J在60℃干燥条件下放置过夜前后的晶型物的XRPD对比图。
条件3:60℃氮气吹扫2h
分别称取10mg至15mg的多晶型物P、F和J置于1.5mL的玻璃瓶内,在氮吹仪中60℃条件下氮气吹扫2h,随后将多晶型物P、F和J进行XRPD测试,测定样品晶型是否变化。图17至19分别为多晶型物P、F和J在60℃条件下氮气吹扫2h前后的晶型物的XRPD对比图。
条件4:室温氮气吹扫过夜
分别称取10mg至15mg的多晶型物P、F和J置于3mL的玻璃瓶内,在氮吹仪中室温下氮气吹扫过夜,随后将多晶型物P、F和J进行XRPD测试,测定样品晶型是否变化。图20至22分别为多晶型物P、F和J在室温下氮气吹扫过夜前后的晶型物的XRPD对比图。
经各多晶型物的XRPD对比图判断,得到多晶型物P、F和J的物理稳定性质,结果见表8。
表8多晶型物P、F和J的物理稳定性质
Figure PCTCN2016106561-appb-000014
对于多晶型物P和F,在四种条件下放置后,晶型均保持不变,多晶型物P和F稳定性好。对于多晶型物F,在条件1下放置后的特征峰与放置前的特征峰相比稍有偏移,但放置后的晶型仍属于多晶型物F。
对于多晶型物J,在40℃/75%RH条件下放置一周后,晶型不变,在其他三种条件下,转化为多晶型物O。
相对生物利用度试验
采用HPLC-MS/MS的方法检测SPF级SD大鼠血浆中目标药物的血药浓度,并对大鼠分别灌胃给予游离碱-0.5%CMC-Na的混悬液和多晶型物P的0.5%CMC-Na溶液的相对生物利用度进行计算比较。
游离碱组的目标药物的0.5%CMC-Na混悬液的配制:精密称取游离碱60.46mg置于15mL离心管中,用量筒量取0.5%CMC-Na溶液12mL至离心管中,涡旋5min,超声15min使分散均匀,即得浓度为5.04mg/ml的游离碱的0.5%CMC-Na混悬液,现配现用且在给药过程中随时振摇。
多晶型物P组的目标药物的0.5%CMC-Na溶液的配制:精密称取60.05mg的多晶型物P置于15mL离心管中,用量筒量取0.5%CMC-Na溶液12mL 至离心管中,涡旋5min,超声15min使分散均匀,即得5.00mg/mL的多晶型物P的0.5%CMC-Na溶液,现配现用。
选用SPF级SD大鼠12只,随机分为游离碱组、多晶型物P组,每组6只(雌雄兼用)。动物禁食不禁水约12h,称重,据动物体重计算每只大鼠的给药体积,使给药剂量均为20mg/kg.bw。给药时,分别灌胃给药,用2mL注射器分别抽取上述两种目标药物的0.5%CMC-Na混悬液/溶液,将灌胃针从大鼠口角处插入胃中推入溶液。
分别于给药前(0h)和给药后0.5、1、2、4、6、8、12和24h,于大鼠眼底静脉丛取血0.2mL,以300IU/mL肝素(1:20)抗凝,离心(3000r/min)15min。分离血浆后用HPLC-MS/MS测定目标药物血药浓度,获得的血药浓度-时间曲线见图23。用DAS2.0软件计算得两组的主要药代参数见表9。
表9游离碱组和多晶型物P组的平均药代参数
Figure PCTCN2016106561-appb-000015
Figure PCTCN2016106561-appb-000016
游离碱组的平均AUC(0-24h)A为288.6ng/mL*h,多晶型物P组的平均AUC(0-24h)P为583.5ng/mL*h,按下式计算相对生物利用度(F):
Figure PCTCN2016106561-appb-000017
即在本实验条件下,多晶型物P相对于游离碱的生物利用度为202%。根据药代参数显示,多晶型物P水溶液达峰更快,且平均达峰浓度更高。
参照上述多晶型物P的生物利用度试验,分别进行多晶型物F、O、B和J的生物利用度试验。与多晶型物P的生物利用度试验不同在于:对大鼠分别灌胃给予多晶型物F、O、B或J的0.5%CMC-Na溶液,其他操作与上述生物利用度试验相同。所得到的结果与多晶型物P的0.5%CMC-Na溶液结果一致,多晶型物F、O、B和J相对于游离碱,生物利用度更好。
多晶型物P、F、O、B和J较游离碱的动态溶解度提高,进入动物体内更易透过细胞膜,更易被吸收,从而生物利用度更高。
应用实施例 强迫游泳试验
采用强迫游泳试验,试验多晶型物P、F、O、B和J的在抗抑郁作用方面的效果。
(1)具体试验环境:游泳试验设备为46cm高、内直径为20cm的透明玻璃圆缸,试验水温为23℃~25℃,试验水深为30cm,且每缸水仅用一次。
(2)具体试剂的配制
溶媒对照液:0.9%的生理盐水。
实验一组的实验试剂的配制:用电子天平称取300mg的多晶型物P,并使用0.9%的生理盐水对多晶型物P进行溶解,最后用0.9%的生理盐水定容至100mL,此时实验试剂中二盐酸盐的浓度即为3mg/mL,备用。
实验二组的实验试剂的配制:用电子天平称取600mg的多晶型物P,并使用0.9%的生理盐水对多晶型物P进行溶解,最后用0.9%的生理盐水定容至100mL,此时实验试剂中二盐酸盐的浓度即为6mg/mL,备用。
阳性对照液的配制:用电子天平称取400mg的地昔帕明(DMI),用0.9%的生理盐水对DMI进行溶解,随后用0.9%的生理盐水定容至100mL,备用。
(3)试验方法
准备SPF级SD大鼠40只,随机分为4组,即溶媒对照组、阳性对照组、实验一组、实验二组,每组10只。试验前一天,将大鼠放入水中15min以预游15min,以适应游泳试验的环境,随后取出擦干,放于笼中置红外灯下15min再放入原鼠笼中。24h后进行正式游泳试验,即24h后大鼠重新放入水中,连续观察5min,游泳过程需进行摄像。在两次游泳期间进行给药。
(4)给药容量和剂量、途径以及周期
按照表10示出的给药容量和途径进行给药。
表10各组别给药的容量(剂量)和途径
Figure PCTCN2016106561-appb-000018
含有DMI的阳性对照组给药三次,分别于正式游泳试验前23.5h、5h以及1h腹腔注射给药;溶媒对照组、实验一组和实验二组分别仅给药一次,于1h皮下注射给药。
(5)行为评分
试验过程的录像每间隔5秒,评分者对大鼠行为进行评分。
对下述三种行为记录:
1)静止-当大鼠漂浮于水面,不挣扎,运动仅是为了保持其头部露出水面,则评价大鼠为静止;
2)游泳-有明显的游泳行为而不仅仅是为了保持头部露出水面,或是在圆缸中环游,则评价大鼠为游泳;
3)爬壁-大鼠前爪有明显进出水面的行为,通常在圆缸壁前,则评价大鼠为爬壁。
所有行为评分均由单人进行,为避免观察的偏向性,评分者仅在不了解给药情况的条件下进行观察,评分。再随机抽取数个试验片断,由评分者进行第二轮评分以确定观察的准确性。试验录像由第二个评分者再次进行评分以确定评分者间的准确性,第二位评分者也要求在不了解给药情况下进行观察,最后为了确定方法的有效性,由第一个评分者再次评分,并用秒表记录各种行为的持续时间。
(6)统计方法
采用SPSSwin11.0软件进行方差分析,方差齐采用单因素方差分析,方差不齐采用Dunnett检验。
(7)试验结果
根据上述行为评分的记录结果和统计方法,得到以下试验结果。
