背景技术
世界范围内,肥胖症已经成为了人类健康的严重威胁。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(FTO基因敲除小鼠,FTO基因过表达小鼠和FTO-I367F突变小鼠)得到了进一步的验证。5-8具体来说,FTO基因全身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5-6,而FTO基因过表达的小鼠则会导致肥胖8。一个FTO基因的错义突变(I367F)会导致FTO蛋白的酶活性降低,从而导致小鼠体重偏低。7FTO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9,这一结果支持了FTO影响机体能量代谢的观点。6
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它首选的底物是信使核糖核酸(mRNA)上的N6-meA,这一修饰化的碱基多分布于信使核糖核酸终止密码子附近,影响着信使核糖核酸的翻译过程。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。所以亟需发现类药性的FTO小分子抑制剂,利用其来研究FTO蛋白的功能,和开发全新的治疗或预防肥胖疾病的药物。
现有的已被批准可供病人使用的药物有着明确的安全评价,所以人们可以快速评价这些药物对于感兴趣的生物学靶点是否有新的治疗用途。在此,我们通过基于结构的虚拟筛选方法,发现了一个已知的美国FDA批准的药物——恩他卡朋作为FTO蛋白的抑制剂,并通过体外酶活实验、细胞实验和高脂饮食诱导的肥胖动物模型检测了恩他卡朋的生物学活性。

与单独给药相比,通过靶向不同通路,共同服用药物可以起到互相补充或协同作用以增加效价。从而与单独使用时相比,允许使用降低剂量或另外的非优化剂量或亚治疗剂量来达到治疗效果,例如表2中所示药物剂量的50%/50%和25%/25%的共同制剂和共同包装。
术语“制药学上可接受的盐”是指包括活性化合物与相对无毒副作用的酸或碱制备的盐的形式,这些酸或碱的选择取决于本文所述化合物上特定的取代基。当本发明化合物含有相对酸性的官能团,碱式加成盐的获得,可以在不加溶剂状态或在合适的惰性溶剂中,通过这类化合物的中性形式和足量的期望的碱结合得到。制药学上可接受的碱形成盐的实例,包括钠盐,钾盐,钙盐,铵盐,有机胺或镁盐或类似的盐。当本发明化合物含有相对碱性的官能团,酸式加成盐的获得,可以在不加溶剂状态或在合适的惰性溶剂中,通过这类化合物的中性形式和足量的期望的酸结合得到。制药学上可接受的酸形成盐的实例,包括那些衍生自无机酸的盐,如盐酸,氢溴酸,硝酸,碳酸,碳氢酸,磷酸,磷酸一氢酸,磷酸二氢酸,硫酸,硫酸一氢酸,氢碘酸或亚磷酸等,以及衍生自相对无毒副作用的有机酸的盐,如乙酸,丙酸,异丁酸,草酸,马来酸,丙二酸,苯甲酸,琥珀酸,辛二酸,富马酸,苦杏仁酸,邻苯二甲酸,苯磺酸,对甲苯磺酸,柠檬酸,酒石酸,甲磺酸等。还包括的是氨基酸所对应的盐,如精氨酸等,以及有机酸的盐,如葡糖醛酸或半乳糖醛酸等。本发明的某些特定的化合物同时包含碱性和酸性官能团,这使得化合物可以使用碱或酸形成盐。
化合物的中性形式可以通过用加入碱或酸和以常规方式分离母体化合物的方式再生。化合物的母体形式在某些物理性质上不同于各种盐形式,如在极性溶剂中的溶解度,但在其他方面,所述盐等同于本发明中化合物的母体形式。
除了盐的形式,该化合物可以以前药形式存在。化合物的前药通过生理条件下化学变化后,生成本发明所述化合物。此外,前药可通过化学或生化方法,在体外环境中转化为本发明所述化合物。例如,前药可以和合适的酶或化学试剂放置在透皮贴剂的储藏器,从而缓慢地转化为本发明所述化合物。前体药通常很有用,因为在一些条件下,前体药比原药更容易使用。比如,口服时,前体药比原药有更好的生物利用度。在药物组合物中前药比原药可能有更好的溶解性。本领域中前药衍生物的各种变化是共知的,例如基于前药的水解或氧化。例如,但不限于此,本发明所包含的化合物的前体药可能是其酯化的形式,在体内代谢后,形成具活性的羧酸化合物。
本发明化合物可以以非溶剂化或溶剂化的形式存在,包括水合物形式。一般来说,溶剂化的形式等价于非溶剂化形式,二者都包括在本发明的范围内。本发明化合物存在多晶型或无定型。一般来说,本发明化合物各种存在的物理形态在使用时是等价的,且都包括在本发明的范围内。
本发明中特定化合物存在非对称碳原子(手性中心)或双键,对映异构体,非对映异构体,各种立体异构体,各种异构体都包括在本发明的范围内。
用于给药的组合物可以采用散装液体溶液的形式或悬浮液,或散装粉末。然而,更常见的是,组合物中提供单位剂型以便于精确的确定剂量。术语“单位剂量形式”是指,对于人类患者和其它哺乳动物适宜作为统一剂量的物理独立单元,每个单元含有预定量的活性物质,目的在于能产生期望的治疗效果,并伴有适当的药学上可接受的赋形剂。典型单位剂型包括预装填,预测量的液体组合物的安瓿或注射器或丸剂,片剂,胶囊,锭剂或类似的固体组合物的情况。
各种适宜的剂型或给药系统,包括适宜的赋形剂、载体和制备给药的组合物的准备方法,是本领域技术人员公知的,更详细的描述参见出版物Remington:The Science and Practiceof Pharmacy(Pharmaceutical Press(2012)。例如,在具体实施方案中的组合物配制在缓释或控释系统,如扩散系统(如贮存设备,矩阵设备,扩散控制植入物和经皮贴剂)和包封和矩阵溶解系统,崩解产品,渗透泵系统,离子交换树脂等。
在具体的实施方案中,给药的剂量远超过目前用于帕金森氏病患者的剂量(如至少2,2.5,5或10次的单位剂量(200mg))。该化合物的给药剂量的优选是0.5-10,0.5-5,0.5-2.5,1-10,1-5,1-2.5,2-10,or 2-5g/天,以0.25,0.5,1,1.5,2or 2.5g的单位剂量。
化合物的给药方式可以有多种方式包括,但不限于此,注射、局部注射、口服或局部给药,比如,喷雾或外敷,来达到治疗和预防的目的。对于有经验的临床医生,治疗手段(比如,药物剂量和给药次数)可以根据具体情况有所调整,如观察到的病人对所给药物的反应情况和观察到的给药后疾病程度的变化。
具体实施方式
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(图一)。
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,0.5μM ssDNA 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nuclease P1和alkaline 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((图二)。
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(图三)。
动物模型中抑制肥胖效果。我们使用高脂饲料(45%fat,OpenSource Diets D12451)喂养23只6周龄的wistar大鼠,随机选择其中12只通过灌胃给予恩他卡朋(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%(*p-value<0.05)(图四)。但是,两组经体重标准化的进食量没有明显区别(图五)。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)(图六和表一)。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,脂肪细胞的尺寸减小和脂肪肝症状减轻。(图七,a,b H&E染色,10倍放大;c,d H&E染色,40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 |
根据这些及其他数据,我们可以得出结论针对病人减重的有效剂量应该远大于帕金森氏症患者所使用的200mg/day的标准单位剂量,优选0.5-10,0.5-5,0.5-2.5,0.5-1,1-10,1-5,1-2.5,2-10,或2-5克/天。
动脉粥样硬化症模型:LDLr-缺失小鼠。我们使用西式饮食饲料(20%脂肪,0.15%胆固醇)喂养的ldlr-/-小鼠模型检测了恩他卡朋治疗或缓解动脉粥样硬化的效果。恩他卡朋(300mg/day)均匀掺在饲料粉末中。8周后,给药组小鼠的主动脉弓斑块面积相对于对照组小28%(p-值为0.08)(图八)。所以,相对于对照,恩他卡朋可以减轻动脉粥样硬化的症状。
肥胖小鼠中抑制肥胖效果。我们使用高脂饲料(45%fat,OpenSource Diets D12451)喂养雄性C57BL/6小鼠八周,从中挑选体重超过正常饲料喂养小鼠体重20%的肥胖小鼠20只进行实验。恩他卡朋(300mg/kg)均匀掺在饲料粉末中,喂养随机挑选的10只肥胖小鼠。13周后,相对于对照组,给药组小鼠平均体重低约11%(p-值<0.05)(图九)。
