Description
技术领域
本发明涉及恩他卡朋在预防或治疗肥胖等代谢综合征中的应用。属于医药技术领域
背景技术
世界范围内,肥胖症已经成为了人类健康的巨大威胁。导致肥胖症,这一慢性疾病的因素包括环境因素和遗传因素。最近,人们利用全基因组关联研究(GWAS,genome-wideassociation studies)方法,对于肥胖病人的单核苷酸多态性(SNP)进行了分析,发现单一基因FTO(fat mass and obesity)基因与肥胖表型显著相关。1-4而且,FTO基因与肥胖的关系在转基因动物模型上得到了进一步的证实。具体来说,FTO基因完全敲除和神经细胞特异敲除的小鼠与野生型相比体重明显偏低,而FTO基因高表达的小鼠则会导致肥胖。FTO基因的错义突变(I367F)会导致FTO蛋白活性降低,从而导致小鼠体重偏低。5-8FTO基因在机体内多个组织中都有表达,特别是下丘脑中控制能量代谢的核团,这一结果支持了FTO影响机体能量代谢的观点。9
FTO蛋白是α-酮戊二酸和亚铁离子依赖的核酸去甲基化酶。9,10它首选的底物是mRNA上的N6-meA。这一修饰化的碱基多分布于mRNA终止密码子附近,影响着mRNA的翻译过程。11,12然而,目前人们对于FTO蛋白的作用机理仍不清楚,特别是FTO蛋白的上游下游作用元件和调控机制尚未报道。所以亟需发现小分子抑制剂,利用其来研究FTO蛋白的活性,更进一步开发新的治疗或预防肥胖疾病的药 物。
恩他卡朋(英文名称:entacapone,IUPAC有机化合物系统命名,2E)-2-氰基-3-(3,4-二羟基-5-硝基苯基)-N,N-二乙基-2-丙烯酰胺,英文名称2E)-2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)-N,N-diethylprop-2-enamide,化学结构如式I或附图1所示)。恩他卡朋是已经被FDA批准上市的药物,用于治疗帕金森病。

具体实施方式
实施例1
基于结构的虚拟筛选。我们针对FTO蛋白的底物结合位点,筛选了1323个FDA已批准的药物,并根据基于物理化学定义的一些标准,比如氢键个数、包埋碳原子的个数和疏水相互作用,删去一些不合理的构象。剩余的构象经过进一步的构象优化和重新计算相对结合自由能。根据结合构象和能量,排名靠前的一个化合物是治疗帕金森氏症的儿茶酚-O-甲基转移酶(COMT,Catechol-O-methyltransferase)的抑制剂恩他卡朋(图1)。
酶活抑制实验。我们通过去甲基化实验测定了恩他卡朋对于FTO蛋白的抑制活性。我们使用了100μl的反应体系,其中含有50mM HEPES buffer(pH=7.0),100μM a-KG,100μM(NH4)2Fe(SO4)2,1mM L-ascorbic acid,50μg/ml BSA,0.5μMssDNA with N6-mA(5’-ATTGTCA(m6A)CAGCAGA-3’),和0.1μM FTO蛋白。反应体系在37℃孵育2小时,95℃5分钟终止反应。ssDNA使用nucleaseP1和alkal ine phosphatase消化。N6-mA和A的浓度通过液质联用仪器检测。当底物浓度为0.5μM,FTO蛋白浓度为0.1μM时,恩他卡朋对FTO蛋白的半数抑制活性IC50值约为9μM(图2)。
细胞甘油三酯合成抑制实验。我们测定了恩他卡朋对于Huh-7肝细胞系甘油三酯合成的抑制活性,IC50值约为15uM。(图3)(建议引用文献的方法)
动物模型中抑制肥胖效果。我们使用高脂饲料(45%fat,OpenSource DietsD12451)喂养23只wistar大鼠,随机选择其中12只通过灌喂给予恩他卡朋(85.6mg/天),其余给予vehicle。给药8周后,给药组大鼠平均体重比对照组低约11%。(图4)但是,两组经体重标准化的进食量没有明显区别。(图5)给药组血清中LDL-c(低密度脂蛋白-胆固醇)较对照组明显降低约40%(p-value<0.005)。(图6和表一)。并且,给药组大鼠脂肪组织和肝组织相比于对照组有明显区别,脂肪细胞减小和脂肪肝症状减轻。(图7,ab,H&E染色,10倍放大;cd,H&E染色,20倍放大)。
表一、恩他卡朋对于大鼠血生化的影响。“变化”是给药组相对于对照组变化的百分比。
指标 | 变化 | p-值 |
胆固醇 | -3.3% | 0.6455 |
高密度脂蛋白-胆固醇HDL-c | -0.026% | 0.9972 |
低密度脂蛋白-胆固醇LDL-c | -41.2% | 0.0005 |
甘油三酯 | -3.8% | 0.8023 |
胆红素 | -10.1% | 0.5814 |
白蛋白比例Albumin ratio | -0.063% | 0.9473 |
谷丙转氨酶 | -5.5% | 0.4962 |
肌酸激酶 | -17.6% | 0.2311 |
动脉粥样硬化症模型。Ldlr(低密度脂蛋白受体)敲除小鼠。我们用高脂饲料喂养了Ldlr基因敲除小鼠。同样,恩他卡朋给药组体重明显低于对照组,血液中LDL-c明显降低。
