背景技术
肥胖主要是能量摄入增加或消耗减少及基因突变等原因造成体内能量平衡被打破,过多的能量以甘油三脂储存于脂肪细胞,而使脂肪细胞变大。目前肥胖已成为世界范围内的慢性病,过去的10年肥胖的发病率不断上升,肥胖不仅本身是一种严重的疾病,还能引起动脉粥样硬化、高血糖、高血脂、高血压等代谢综合征,而且肥胖呈现多龄化、低龄化倾向。节食和运动是治疗肥胖最安全有效的方法,不过对肥胖患者来说,单纯采用节食和运动并不能够有明显的效果,所以减肥药物和功能性食品受到越来越多的重视。

实施例1
S13和S28,S31-S38所示化合物的制备
(1)制备灵芝的提取物
将灵芝子实体剪碎,称重5千克。用15L 95%乙醇-水(体积百分含量)溶液回流提取3次,每次1小时。合并提取液,减压浓缩干燥得到170克提取物。
进一步将提取物用蒸馏水600ml溶解,用等体积的正己烷萃取三次,弃去有机相。再用等体积乙酸乙酯萃取水相三次,弃去水相,合并乙酸乙酯萃取液。用旋转蒸发仪(RE-52AA,购自上海亚荣生化仪器厂)蒸干乙酸乙酯获得浸膏54g,记作LZ-E。
(2)化合物的制备
将步骤(1)制备的LZ-E通过硅胶柱色谱分离,以正己烷:乙酸乙酯体系(正己烷:乙酸乙酯的体积比为9:1,4:1,7:3,1:1)进行梯度洗脱,每个梯度洗3个保留体积,每个体积500ml。根据薄层层析色谱行为分析,在正己烷:乙酸乙酯(体积比为9:1)体系得到馏分LZ-E1;在正己烷:乙酸乙酯(体积比为4:1)中得到馏分LZ-E2~LZ-E3;在正己烷:乙酸乙酯(体积比为7:3)中得到馏分LZ-E4,LZ-E5;在正己烷:乙酸乙酯(体积比为1:1)中得到馏分LZ-E6;共得到6个馏分,将各馏分冷冻干燥。
通过薄层色谱分析发现LZ-E4中活性物质含量较高,因此对该馏分利用ODS反相硅胶柱进一步分离。用体积百分含量为10%,20%,30%,40%,50%,70%,90%的甲醇水溶液依次进行洗脱,每个洗脱体系洗3个保留体积,每个保留体积为500ml。根据薄层层析色谱行为,照射254nm紫外灯判断不同馏分,在体积百分含量为10%的甲醇水溶液中得到馏分LZ-E4-1;在体积百分含量为20%的甲 醇水溶液系统中得到馏分LZ-E4-2~LZ-E4-4;在体积百分含量为30%的甲醇水溶液系统中得到馏分LZ-E4-5~LZ-E4-10;在体积百分含量为40%的甲醇水溶液系统中得到馏分LZ-E 4-11~LZ-E 4-14;在体积百分含量为50%的甲醇水溶液系统中得到馏分LZ-E4-15~LZ-E4-18;在体积百分含量为70%,90%的甲醇水溶液系统中得到馏分LZ-E4-19~LZ-E4-23;共得到23个子馏分,将各个馏分冷冻干燥。
通过薄层色谱分析发现LZ-E4-12中活性物质含量较高,因此对LZ-E4-12馏分进一步进行HPLC分离。以体积百分含量56%乙腈的酸水(此处的酸水为体积百分含量为0.01%三氟乙酸的水溶液)溶液为洗脱剂进行HPLC制备,流速为2ml/min,收集18.9,21.2,24.5,26.2,30.2,35.8min的色谱峰,得到得到式S31,S32,S33,S34,S35,S36所示的化合物.
通过薄层色谱分析发现LZ-E4-14中活性物质含量较高,因此对LZ-E4-14馏分进一步进行HPLC分离。以体积百分含量52%乙腈的酸水(此处的酸水为体积百分含量为0.01%三氟乙酸的水溶液)溶液为洗脱剂进行HPLC制备,流速为2ml/min,收集21.1min的色谱峰,得到LZ-E4-14-1;对LZ-E4-14-1进行45%乙腈的HPLC手性拆分,流速2ml/min,收集31.1min,32.5min的色谱峰,分别得到式S13,S28所示的化合物.
通过薄层色谱分析发现LZ-E4-18中活性物质含量较高,因此对LZ-E4-18馏分进一步进行HPLC分离。以体积百分含量46%乙腈的酸水(此处的酸水为体积百分含量为0.01%三氟乙酸的水溶液)溶液为洗脱剂进行HPLC制备,流速为2ml/min,收集15.4min的色谱峰,得到LZ-E4-18-1;对LZ-E4-18-1进行40%乙腈的HPLC手性拆分,流速2ml/min,收集25.1min,26.4min的色谱峰,分别得到式S37,S38所示的化合物.
上述薄层色谱的条件如下:

实施例4
S1-S38所示化合物对脂肪分解的影响
供试样品溶液:准确称取实施例3所制备的S1-S38所示的38个化合物,用DMSO配制成2mM,供活性测试(终浓度20μM,配制时溶于少量DMSO后,用蒸馏水稀释至相应浓度,控制DMSO的最终体积分数<0.1%);异丙肾上腺素10μM作为阳性对照,配制时溶于少量DMSO后,用蒸馏水稀释至相应浓度,控制DMSO的最终体积分数<0.1%。
SD大鼠原代成熟脂肪细胞的分离与培养:雄性SD大鼠,脱臼处死,取附睾脂肪组织,用含有双抗的PBS溶液清洗3次,然后剪成1mm3左右小块,,加入含有I型胶原酶的PBS(1mg/ml I型胶原酶、120mmol/L NaCl,4.8mmol/L KCl,2.5mmol/L CaCl2,1.2mmol/LKH2PO4,1.2mmol/L MgSO4,15mmol/L NaHCO3,25mmol/L Hepes,200nmol/L腺苷,1%BSA,PH7.4),水浴37摄氏度,100rpm40min。1000um尼龙膜过滤300rpm离心3min收集细胞,用无酚红DMEM培养液清洗细胞,重复3次,37摄氏度,5%二氧化碳培养箱中孵育2小时。
肥胖细胞模型的建立:300rpm离心3min收集孵育24小时的成熟脂肪细胞,按细胞压积每管100ul细胞加入到5ml带盖离心管中,然后实验组加入含OA浓度为0.5mmol/L OA的DMEM培养液,对照组加入正常DMEM培养基,孵育24小时,500rpm,离心3min,收集细胞,即为肥胖细胞。
肥胖细胞在OA作用24小时后500rpm,离心3min,清洗三遍去除残留OA,然后按照20ul细胞压积/500ulDMEM将细胞分装于1.5ml EP管中(对照组DMEM中含有相同浓度的DMSO,实验组DMEM中含有不同的受试样品)。本实验选用异丙肾上腺素作为阳性药物。24小时后收集细胞培养液,200rpm离心30秒,收集细胞培养液,70摄氏度加热10分钟灭火甘油分解酶,然后利用甘油测定试剂盒490nm测定培养液中甘油释放量。
结果如表2所示,S5/S8/S9/S13/S20/S24/S28显著刺激脂肪细胞发生脂解, 可以作为减肥药物的候选化合物进行下一步筛选。

实施例5
S5、S8、S9、S13、S20、S24、S28所示7个化合物对高脂饲料诱导的肥胖小鼠体重和进食量的影响
材料:被测样品溶液为实施例3所述的S5、S8、S9、S13、S20、S24、S28的7个化合物。准确称取各样品,用0.5%CMC-Na配制成10mg/ml溶液,供活性 测试。ICR小鼠(8周龄,雄性,D12492高脂喂养5周)购自北京维通利华实验动物技术有限公司,温度20-24摄氏度,恒湿50-60%,光照12小时(8:00-20:00),隔音,自由摄食、饮水,适应环境一周后进行实验。
方法:取200只雄性健康ICR小鼠,22-24g,小鼠适应性饲养一周后进行实验。随机选取10只作为对照组,给与普通饲料。剩余190只给与D12492高脂饲料。饲养4周后,根据体重进行筛选(与对照组相比,体重增加15%入选),最终筛选得到106只。随机分为9组(7个给药组+模型组+阳性药罗格列酮组),各给药组分别按照3mg/kg灌胃给药。
(1)每周测定各组体重并记录进食量;
(2)给药5周结束后,小鼠禁食4小时后麻醉处死,称重、计算Lee指数测量肝脏、肾脏重量,计算脏器/体重比;
Lee指数=[体重(g)/体长(cm)]^(1/3)
(3)取血,利用北京福德安科技有限公司小鼠GLP-1ELISA试剂盒(批号201606)、小鼠GIP ELISA试剂盒(批号201606)、小鼠CCK8试剂盒(批号201606)、小鼠MTL试剂盒(批号201606)、小鼠Ghrelin试剂盒(批号201606)测量肠道激素相关指标(GLP1:胰高血糖素样肽1,GIP:葡萄糖依赖性胰岛素释放多肽,CCK8:胆囊收缩素,MTL:胃动素,Ghrelin:胃饥饿素)。测定方法参照
(4)无菌操作取盲肠部分粪便,-80℃保存,测定肠道益生菌。
按照《保健食品检验与评价技术规范》(2003),取粪样均质液以10倍梯度稀释,分别接种到相应培养基上培养,采用平板计数法对样品中的双歧杆菌、乳酸杆菌和粪肠球菌计数。
结果:与对照组相比,模型组体重明显增加,罗格列酮组没有明显变化,S5/S9/S13在第三周后与模型组出现显著差异,在5周进食量的统计中,7个给药组小鼠的食量均受到抑制,在Lee指数的测定中,S5/S9/S13/S24/S28这5个给药组的Lee指数明显低于模型组,且S5/S9/S13这3个组的肾脏指数明显高于模型组。

S5、S8、S9、S13、S20、S24、S28所示7个化合物对小鼠胃排空及小肠推进的影响
材料:被测样品溶液为实施例3所述的S5、S8、S9、S13、S20、S24、S28所示7个化合物。准确称取各样品,用0.5%CMC-Na配制成10mg/ml溶液,供活性测试。ICR小鼠(8周龄,雄性,D12492高脂喂养5周)购自北京维通利华实验动物技术有限公司,温度20-24摄氏度,恒湿50-60%,光照12小时(8:00-20:00),隔音,自由摄食、饮水,适应环境一周后进行实验。

排空率=(1-小鼠胃酚红A)/酚红A基值*100%
以胃酚红排空率胃指标评价胃排空速度。小肠推进则以酚红在小肠中的移行距离与小肠全长的百分比乘以100%作为小肠推进率来评价小肠推进速度。
如表5所示,与空白对照相比,这7个化合物都有一定的抑制胃排空作用,特别是化合物S5/S8/S9/S13这四个化合物在抑制胃酚红排空率和小肠推进率方面都非常显著。
