Abstract

本发明涉及α‑细辛醇酯及其制备方法与应用。所涉及的α‑细辛醇酯的化学结构通式如式I所示。所涉及的应用为上述化合物用于制备镇静、安神、抗老年痴呆、抗惊厥、抗癫痫、抗抑郁药物的应用。

Description

α-细辛醇酯及其制备方法与应用
技术领域
本发明主要涉及α-细辛醇酯的制备方法及其用于镇静、安神、抗老年痴呆、抗惊厥、抗癫痫、抗抑郁的药物研究。
背景技术
石菖蒲,首次记录于《神农本草经》,为上品,来源于天南星科多年生草本植物石菖蒲Acorus tatarinowii Schott.的干燥根茎。性温,味辛、苦。入心、胃经,具有芳香之气,辛温行散之力,可以化湿和胃,又可化痰开窍,具有益智醒神等功效,常用于治疗中风、痰厥癫痫、神昏、健忘等。主要化学成分为挥发油、氨基酸和糖类等,挥发油主要含有β-细辛醚,α-细辛醚等。现代药理研究认为,石菖蒲具有抗痴呆、神经细胞保护、抗突变、抗癫痫等作用。
远志,首次收录于《神农本草经》,为上品,来源于远志科植物远志Polygalatenuifalia Willd.或卵叶远志Polygala sibirica L.的干燥根。远志味苦、辛,性温。具有益智安神、消痰驱肿之功效。远志中化学成分主要包含三萜皂苷类、糖酯类、酮类,也含有少量的生物碱、香豆素、木质素等。研究表明,远志在抗痴呆、脑保护、镇静、抗惊厥、抗抑郁、祛痰镇咳、保护心脑血管等方面具有良好活性。
王莎莎等通过给大鼠口服远志提取物后,在血和胆汁中发现了能延长小鼠戊巴比妥钠睡眠时间的活性物质3,4,5-三甲氧基肉桂酸(TMCA)、甲基3,4,5-三甲氧基肉桂酸(M-TMCA)和对甲氧基肉桂酸(PMCA),提示远志水提物中含有TMCA的天然前体药物。[WangS.S.Wakan Iyakugaku Zasshi,1995,12(2),102]
凌仰之等对TMCA进行结构拼合,得到了3,4,5-三甲氧基肉桂酰胺类化合物,发现其具有很好的抗惊厥活性。[凌仰之,医药工业,1987,18(2):56]
基于远志中TMCA和石菖蒲中α-细辛醚在镇静、安神、抗惊厥、神经细胞保护等方面具有很好的药理活性,我们通过结构及药效团拼合设计了3,4,5-三甲氧基肉桂酸α-细辛醇酯及以α-细辛醇为核心的一系列酯类衍生物,以期在抗老年痴呆、脑保护、镇静、抗惊厥、抗抑郁等方面筛选得到更具疗效的化学新药。

3,4,5-三甲氧基肉桂酸α-细辛醇酯的活性研究
3,4,5-三甲氧基肉桂酸α-细辛醇酯用于治疗惊厥与癫痫。所使用抗癫痫药理实验釆用美国国立卫生研究院(NIH)实施的抗癫痫药开发程序。包括评价抗癲痫活性的最大电惊厥实验法(MES)及考察神经毒性的旋转法(Rotarodtest)。为了进一步研究并评价药物在不同化学模型中的抗惊厥药理机制,采用戊四唑、3-巯基丙酸等2种经典化学模型予以评价。
(1)最大电惊厥实验(MES)
MES是癫痫大发作的常用实验模型,受试化合物若能显著对抗MES,则该化合物有可能开发成临床上治疗癫痫大发作有效的药物。
方法:KM小鼠在试验前进行初步筛选,合格后方能用于下一步实验。筛选方法如下:实验前一天,对实验小鼠采用15V,60Hz的电刺激,两电极夹于小鼠双耳,通电剌激0.45s,出现后肢强直的小鼠属于试验备用小鼠,用于后期实验。抗最大电惊厥实验测定方法为:受试化合物溶解后,灌胃给药,分别在给药后0.25h、0.5h、1h、2h、3h、4h使用0.45s,15V,60Hz的耳电极刺激,如果小鼠不出现后肢强直,则表明该受试化合物在该剂量下具有抗惊厥活性。按照一定的给药规律,设计出梯度浓度,分别给予不同梯度浓度的受试化合物,观察记录其抗惊厥活性,最后计算出受试化合物抗最大惊厥活性的半数有效量(ED50)。依照下面的公式进行计算:
ED50=lg-1[Xm-i(∑P-0.5)]
SX50=i(∑P-∑P2/n-1)1/2
ED50的95%可信限=lg-1(lgED50±1.96SX50)
公式中符号的意义如下:
Xm 最大剂量的常用对数;
i 剂量间比例值的常用对数;
P 每组的阳性率,以小数表示;
n 每组的动物数;
SX50 lgED50的标准误;

b在灌胃给药后0.25h、0.5h、1h、2h、3h、4h进行最大电惊厥实验;
c测试小鼠数量为6只;
d ED50为半数有效量;
e在括号中给出的95%置信限;
(2)神经毒性实验(Neurotoxicity)
方法:实验小鼠灌胃给药,分别在给药后0.25h、0.5h、1h、2h将小鼠放置在转棒式疲劳仪上,以16转/分旋转。在3min内试验小鼠不落下或者落下3次以内,就表明该化合物在该剂量下没有神经毒性;落下3次以上则认为该化合物在该剂量下有神经毒性。按照给药规律设计梯度浓度,分别给予不同梯度剂量旳受试化合物,计算半数中毒量(TD50)。依照下面的公式进行计算:
TD50=lg-1[Xm-i(∑P-0.5)]
SX50=i(∑P-∑P2/n-1)1/2
TD50的95%可信限=lg-1(lgTD50±1.96SX50)
公式中符号的意义如下:
Xm 最大剂量的常用对数;
i 剂量间比例值的常用对数;
P 每组的阳性率,以小数表示;
n 每组的动物数;
SX50 lgTD50的标准误;

b在灌胃给药后0.25h、0.5h、1h、2h进行神经毒性实验;
c测试小鼠数量为4只;
d TD50为半数中毒量;
e ED50为半数有效量;
f PI为保护指数(TD50/ED50);
g在括号中给出的95%置信限;
通过测定后的实验数据计算得出,3,4,5-三甲氧基肉桂酸α-细辛醇酯在灌胃给药下对抗最大电惊厥实验的ED50=90.3mg/kg,TD50=939.7mg/kg,保护指数PI为10.4,显示出很好的抗惊厥活性,且未显示出明显毒性。
为了推断出3,4,5-三甲氧基肉桂酸α-细辛醇酯可能的抗惊厥机制,本研究采用戊四唑、3-巯基丙酸等化学试验模型对受试化合物(i.g:160mg/kg、80mg/kg、40mg/kg)的初步抗惊厥活性进行了评价。
(3)戊四唑诱发的实验性癫痫模型
方法:实验小鼠随机分成5组,分别为给药组(i.g:160mg/kg、80mg/kg、40mg/kg)、对照组和空白组,每组6只,给药组灌胃受试化合物,对照组灌胃阳性药卡马西平,空白组灌胃生理盐水,30分钟后,给予灌胃戊四唑200mg/kg,受试动物单独放置于一个鼠笼中观察60分钟,记录下每组小鼠阵挛性发作的潜伏时间、阵挛性发作个数、强直性发作个数及死亡个数。
表3.3,4,5-三甲氧基肉桂酸α-细辛醇酯对抗戊四唑引起的小鼠抗惊厥活性结果
**与生理盐水组比较p<0.01;*与生理盐水组比较p<0.05
在对抗戊四唑化学药物诱导的惊厥模型试验中,与生理盐水组相比,试验剂量下(160mg/kg、80mg/kg、40mg/kg)的3,4,5-三甲氧基肉桂酸α-细辛醇酯均能显著延长小鼠阵挛性发作的时间(p<0.05),且能抑制小鼠强直性发作,降低小鼠死亡率;与卡马西平相比,同等剂量下3,4,5-三甲氧基肉桂酸α-细辛醇酯对试验小鼠抑制强直性发作和减少死亡率效果相当。戊四唑是通过抑制γ-氨基丁酸(GABA)神经递质引起惊厥,GABA是存在于大脑中的主要抑制性神经递质,与癫痫有着密不可分的关系。根据表3,3,4,5-三甲氧基肉桂酸α-细辛醇酯可能是通过增加GABA神经递质,来抑制或减少戊四唑诱导的小鼠发生惊厥。
(4)3-巯基丙酸诱发的实验性癫痫模型
方法:实验小鼠随机分成5组,分别为给药组(i.g:160mg/kg、80mg/kg、40mg/kg)、对照组和空白组,每组6只,给药组灌胃受试化合物,对照组灌胃阳性药卡马西平,空白组灌胃生理盐水,30分钟后,给予灌胃3-巯基丙酸60mg/kg,受试动物单独放置于一个鼠笼中观察60分钟,记录下每组小鼠阵挛性发作的潜伏时间、阵挛性发作个数、强直性发作个数及死亡个数。
表4.3,4,5-三甲氧基肉桂酸α-细辛醇酯对抗3-巯基丙酸引起的小鼠抗惊厥活性结果
*与生理盐水组比较p<0.05
在对抗3-巯基丙酸化学药物诱导的惊厥模型试验中,与生理盐水组相比,160mg/kg、80mg/kg的3,4,5-三甲氧基肉桂酸α-细辛醇酯均能显著延长小鼠阵挛性发作的时间(p<0.05),且能抑制小鼠阵挛性发作和强直性发作,降低小鼠死亡率;与卡马西平相比,160mg/kg、80mg/kg的3,4,5-三甲氧基肉桂酸α-细辛醇酯对试验小鼠抑制强直性发作和减少死亡率效果相当。3-巯基丙酸是GABA合成酶谷氨酸脱羧酶竞争性抑制剂,会抑制GABA的合成导致GABA脑内水平减少。3,4,5-三甲氧基肉桂酸α-细辛醇酯能适度对抗3-巯基丙酸诱导的惊厥,说明3,4,5-三甲氧基肉桂酸α-细辛醇酯可能活化GABA合成酶谷氨酸脱羧酶或抑制脑内GABA。
