  • ACC acetyl-CoA carboxylase
  • Acetyl-CoA carboxylase is one of the important proteins involved in fatty acid metabolism. It uses biotin as a coenzyme to catalyze the production of malonyl-CoA from acetyl-CoA. This irreversible reaction (malonyl-CoA), in turn, provides a substrate for the synthesis of subsequent fatty acids or modulates the fatty acid oxidation signal, which is the first step of fatty acid metabolism and is a rate limiting step. The catalytic reaction can be divided into two steps, depending on the biotin carboxylase (BC) and carboxyltransferase (CT) activities of ACC.
  • BC biotin carboxylase
  • CT carboxyltransferase
  • ACC1 is a cytosolic enzyme that is mainly expressed in fat synthesis tissues (such as fat and breast tissue); ACC2 is localized in the mitochondrial membrane and is mainly enriched in oxidized tissues (such as the heart). In skeletal muscle, both are expressed at high levels in the liver. Therefore, ACC1 is mainly involved in the regulation of fatty acid synthesis, and ACC2 is mainly responsible for the regulation of the oxidation process of fatty acids.
  • the activity of ACC is regulated by a variety of proteins, cytokines, endocrine hormones and receptors.
  • AMPK is the main substance regulating ACC activity, which can inhibit the activity by direct phosphorylation of ACC; and protein phosphorylase 2 can dephosphorylate ACC, thereby enhancing the effect of ACC.
  • free fatty acids synthesized in the cytosol are transported to the mitochondria via the mitochondrial membrane on carnitine palmitoyltransferase 1 (CPT1) for oxidative energy supply.
  • CPT1 carnitine palmitoyltransferase 1
  • Malonyl-CoA in the cytosol allosterically inhibits CPT1, leaving its activity at a lower level, thereby limiting fatty acid oxidation.
  • the AMPK pathway can be activated immediately, the downstream ACC is inactivated, the level of malonyl-CoA is rapidly decreased, the inhibition of CPT1 is further relieved, and the oxidation of fatty acids is promoted to provide the body with More adenosine triphosphate (ATP).
  • ATP More adenosine triphosphate
  • Increased fatty acid synthesis and fatty acid metabolism disorders caused by impaired fatty acid oxidation are common features of many metabolic diseases, including liver steatosis, dyslipidemia, obesity, metabolic syndrome, nonalcoholic fatty Hepatitis (NASH), type 2 diabetes (T2DM) and atherosclerosis.

Description

氰基取代的杂芳基并嘧啶酮类衍生物及其制备方法和用途
本申请要求于2017年3月24日提交中国专利局、申请号为201710182808.X、发明名称为“氰基取代的杂芳基并嘧啶酮类衍生物及其制备方法和用途”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种氰基取代的杂芳基并吡啶酮类衍生物、其制备方法、含有该衍生物的药物组合物以及其作为治疗剂特别是作为乙酰辅酶A羧化酶(ACC)抑制剂的用途。
背景技术
乙酰辅酶A羧化酶(Acetyl-CoA carboxylase,ACC)是参与脂肪酸代谢过程的重要蛋白之一,它以生物素(biotin)为辅酶,催化乙酰辅酶A(acetyl-CoA)生成丙二酰辅酶A(malonyl-CoA)这一不可逆反应,进而为后续脂肪酸的合成提供底物或调节脂肪酸氧化信号,该反应为脂肪酸代谢的第一步反应且为限速步骤。该催化反应可分为两步,分别依赖于ACC所具有的生物素羧化酶(biotin carboxylase,BC)和羧基转移酶(carboxyltransferase,CT)活性。
人体中ACC存在2个亚型,分别为ACC1和ACC2,其分别由ACACA和ACACB两个基因单独编码表达。两者在组织分布和细胞内分布上存在差异,ACC1是胞浆酶,主要在脂肪合成组织(如脂肪及乳腺组织)中高水平表达;ACC2定位于线粒体膜,主要富集在氧化组织(如心脏和骨骼肌)中,在肝脏中两者均以高水平表达。因此,ACC1主要参与调节脂肪酸的合成,ACC2主要负责脂肪酸的氧化过程调节。ACC的活性受多种蛋白、细胞因子、内分泌激素及受体调控。其中AMPK是调节ACC活性的主要物质,可通过直接磷酸化ACC以抑制其活性;而蛋白磷酸化酶2可使ACC去磷酸化,从而增强ACC的作用。生理条件下,胞浆中合成的游离脂肪酸通过线粒体膜上的肉碱棕榈酰转移酶1(CPT1)运送至线粒体内进行氧化供能。而胞浆中的丙二酰辅酶A变构抑制CPT1,使其活性处于较低水平,从而限制脂肪酸氧化。当机体处于应激或能量消耗增加时,可立即激活AMPK途径,使其下游ACC失活,丙二酰辅酶A水平迅速下降,进一步解除对CPT1的抑制作用,促进脂肪酸氧化供能,为机体提供更多的三磷酸腺苷(ATP)。
脂肪酸合成的增加和脂肪酸氧化受损所导致的脂肪酸代谢失调是多种代谢 类疾病的共同特点,其涉及的疾病包括:肝脂肪变性、血脂异常、肥胖症、代谢综合征、非酒精性脂肪性肝炎(NASH),2型糖尿病(T2DM)以及动脉粥样硬化。此外,脂肪酸代谢异常也是肿瘤疾病的特征之一,参与调节恶性肿瘤异常的细胞增殖过程。由于ACC作为脂类代谢的关键调节蛋白,药物抑制ACC可在限制脂源组织中的脂肪酸的合成的同时,在氧化组织中刺激促进脂肪酸的氧化,因此为治疗上述存在脂类代谢异常的疾病提供了一种极具吸引力的治疗方式。
目前已经公开了一系列的ACC抑制剂专利,其中包括WO2014182943、WO2014182945、WO2014182950等,目前处于临床II期的药物主要为GS-0976。但这些现有技术中公开的化合物以及试验药物在有效性、安全性或适用性等方面仍不能令人满意,目前对于ACC抑制剂的研究也是远远不够的,仍有必要研究和开发新的ACC抑制剂,以满足人们不断增长的医疗和健康需要。
发明内容

因此,在第一个方面,本发明提供了一类新的如下式(I)所示的氰基取代的杂芳基并嘧啶酮类衍生物:

生物学评价
测试例1、本发明化合物对ACC1和ACC2的酶活性抑制IC 50的测定
以下方法用于测定本发明优选化合物在体外条件下对重组人源ACC1、ACC2蛋白的酶活性的抑制程度。
本方法原理基于由ACC蛋白催化乙酰辅酶A生成丙二酰辅酶A的反应。该反应过程中会消耗ATP并生成ADP。通过采用来自Promega(普洛麦格)的ADP-Glo TM激酶试剂盒可以将反应生成的ADP重新转化为ATP,这部分ATP可与试剂盒中的荧光素酶-荧光素发生反应,并生成化学发光信号。因此通过测量化 学发光信号的强度,可以反映催化反应中生成的ADP量,从而间接测定ACC蛋白的酶活性以及受试化合物对于酶活性的影响。所使用的主要试剂包括:ACC1,ACC2蛋白(购于BPS bioscience,ACC1货号50200,ACC2货号50201),乙酰辅酶A(acetyl-CoA,购于Sigma,货号A2056),NaHCO3(购于Sigma,货号S6014),ADP-Glo TM Kinase assay kit(购于Promega,货号V9102)。
测试流程简述如下:首先配制反应所需的1x缓冲液,其组成如下:50mM HEPES(pH7.4购于Invitrogen,货号15630),2mM氯化镁(MgCl 2,购于Sigma,货号M1028),2mM柠檬酸钾(Potassium citrate,购于Sigma,货号89306),0.01%Brij-35 detergent(购于Merck,货号203728),2mM DTT(购于Sigma,货号D0632)。将测试用化合物粉末溶解于DMSO配制为10mM浓度的贮存液,随后依次进行3倍稀释配制成测试所需浓度,每个化合物设10个浓度点,浓度范围为10μM-0.5nM。首先向384孔微孔板中加入适量的ACC蛋白(2nM),再向各孔中加入已稀释好的不同浓度的测试化合物溶液,每个浓度设有复孔对照,同时设置溶剂对照(空白组),阴性对照组(DMSO组)。随后将384孔板在微孔板振荡器上振荡混匀后,在室温条件下孵育15分钟。之后向各孔中加入以前述缓冲液稀释的含有ATP,乙酰辅酶A和NaHCO3的底物混合液以开始反应,三组分的终浓度分别为ATP 20μM,乙酰辅酶A 10μM,NaHCO3 30mM。在室温下反应30分钟后,依照ADP-Glo TM Kinase assay kit试剂盒说明书中的方法,向各孔中加入对应的反应液和检测液(具体操作方法可参考试剂盒说明书),最后在Envision 2104多功能酶标仪(Perkin Elmer)上测定各孔的相对光单位(RLU)数值。某一浓度下化合物抑制ACC酶活性的百分比抑制率按以下公式进行计算:
抑制率%=[(阴性对照孔RLU平均值-空白孔RLU平均值)-(测试孔RLU平均值-空白孔RLU平均值)]/(阴性对照孔RLU平均值-空白孔RLU平均值)*100
最后在GraphPad Prism5软件中对化合物的浓度对数值和相应浓度的百分比抑制率进行非线性回归分析得到该化合物的半数抑制浓度值(IC 50)。
