是中国传统中药厚朴的主要活性成分。1930年日本杉井首先从中国厚朴树皮中分离得到了厚朴酚(中草药;2005,36,10,1591-1594)。1989年中国的孟丽珍等也从厚朴分离到和厚朴酚(中成药:1989,11(8):223.)。
厚朴酚以及和厚朴酚具有抗菌,抗炎,抗肿瘤,肌肉松弛,降胆固醇和抗衰老等广泛的药理作用(中草药;2005,36,10,1591-1594),但是厚朴酚以及和厚朴酚的水溶性很差,严重限制了其在医药上的广泛应用,有待改进。后来厚朴酚以及和厚朴酚的水溶性通过化学衍生化得以改进(CN103113264B),该专利给出了水溶性厚朴酚衍生物以及和厚朴酚衍生物的实验室制备方法。但是该类药物的传统药物代谢动力学研究发现其代谢速度较快且回收率低,不利于科研工作者充分了解该类药物在体内吸收、分布、代谢和***的全过程。

二、实验方法:
选用雄性KM小鼠(体重26-30g),随机分别为:假手术组(Sham)、生理盐水组(Vehicle)、化合物12,所有药物的给药剂量均为100μg/kg。
用5%水合氯醛(500mg/kg,i.p.)麻醉,制备tMCAO模型:将小鼠仰卧位固定于37℃恒温手术台上。颈部正中偏右剪开约1cm的切口,钝性分离胸锁乳突肌和胸骨舌骨肌间的肌间隙,暴露分离出颈总动脉(CCA),颈内动脉(ICA)和颈外动脉(ECA)。在CCA上系一活结,将ECA的远心端结扎,并在其近心端系一活结,ICA用动脉夹夹闭。将ECA上的分支血管凝断,在ECA远心端(两结之间)剪一小口,将一根尼龙栓线经切口处缓慢插向ECA近心端,略微系紧ECA近心端的活结以防止出血,松开ICA的动脉夹,凝断ECA远心端(远心端结外),将ECA拉向与ICA呈直线,将栓线经CCA分叉处***ICA。以CCA分叉处为标记,平均进线10±2mm,感到轻微阻力时,即达到大脑中动脉(MCA)的起始点处,停止进线,收紧ECA根部的活结,固定栓线。阻断MCA血液供应90min后,撤出栓线,结扎动脉残端,松开CCA上的活结,缝合皮肤,完成缺血再灌注损伤手术。假手术组只分离血管,不***栓线。
再灌注24h后,用5%水合氯醛麻醉,用冷的生理盐水(NS)经左心房进行灌注,然后快速开颅取出全脑置于载玻片上,于-20℃冷冻20-25分钟。沿冠状面切片,切成均匀厚度的5片,置于盛有2ml 1%TTC溶液的培养皿中37℃避光孵育30分钟(15分钟翻面一次使其染色均匀)。染色结束后,将脑片置于4%多聚甲醛中4℃固定过夜。正常脑组织呈鲜红色,梗 死脑组织呈白色。用数码相机(PowerShot G12,Canon)照相后,利用photoshop软件测量各脑片梗死面积。根据以下公式算得梗死区域所占比例:{[梗死体积-(全脑体积–对侧半脑体积×2)]/对侧半脑体积}×100%。
三、实验结果
结果如下表3所示,化合物12和化合物13在小鼠缺血性脑卒中tMCAO模型中能明显减少脑梗死体积,图1小鼠缺血-再灌注后24h时经TTC染色的代表性,两者都说明供试化合物起到脑保护用,是潜在的临床缺血性脑卒中的治疗药物。
