Description

β-氨基羰基类化合物、其制备方法、药物组合物及其用途
技术领域
本发明属于药物化学领域。具体而言,本发明涉及一种通式I所示的新的β-氨基羰基类化合物或其互变异构体、对映体、消旋体或其药学上可接受的盐,其制备方法,药物组合物及其作为二肽基肽酶IV(DPP-4)抑制剂的用途。该类化合物或其药物组合物作为DPP-4抑制剂可用于治疗II型糖尿病、高血糖症、肥胖症或胰岛素抵抗症。
背景技术
糖尿病(diabetes)是由遗传因素、免疫功能紊乱、微生物感染及其毒素、自由基毒素、精神因素等等各种致病因子作用于机体导致胰岛功能减退、胰岛素抵抗等而引发的糖、蛋白质、脂肪、水和电解质等一系列代谢紊乱综合征,临床上以高血糖为主要特点,典型病例可出现多尿、多饮、多食、消瘦等表现,即“三多一少”症状。糖尿病(血糖)一旦控制不好会引发并发症,导致肾、眼、足等部位的衰竭病变,且无法治愈。
近年来,糖尿病的发病率逐年攀升,成为21世纪人类健康的主要威胁之一,其中II型糖尿病占90%以上。胰岛素抵抗和胰岛素分泌功能受损是II型糖尿病发病和病理过程之中的两个重要现象。目前临床上使用的降糖药物都存在不同程度的副作用和局限性:磺脲类和胰岛素类降糖药物增加体重并伴随低血糖风险;噻唑烷二酮类胰岛素增敏剂的代表药物——罗格列酮因可能增加糖尿病患者心血管疾病的风险,而在全球范围内退市或被限制使用;吡格列酮也在2011年标注膀胱癌风险;二甲双胍和α糖苷酶抑制剂则存在不同程度的消化道反应;胰岛素不能口服给药。DPP-4抑制剂因具有良好的血糖控制、低血糖发生风险小和不影响体重等优势已成为当下最热门的抗糖尿病药物。
目前,已有5个DPP-4抑制剂上市用于治疗糖尿病,它们分别是西他列汀(sitagliptin)、维达列汀(vildagliptin)、沙格列汀(saxagliptin)、阿格列汀(alogliptin)、利拉利汀(linagliptin)。
本发明的目的在于提供一种新的具有DPP-4抑制活性,可用于糖尿病及类似疾病的治疗或缓解性药物的化合物。

分子对接技术评估化合物活性
计算机辅助药物设计是合理药物设计的主要方法和工具。本发明通过反复尝试各种对接程序、确定了分子对接方法,优化了分子对接参数,获得了DPP-4抑制剂的构效关系,可用于设计符合通式I所示的新型DPP-4抑制剂。优选的对接用计算程序为Schrodinger2010版中的glide(LLC,New York,NY)。对接靶点选用与sitagliptin共结晶的DPP-4蛋白结构(PDB ID:1X70)。对接的范围设置为一个包括DPP-4催化结合位点中的S1、P1和P2口袋的立方体。所有设计的化合物结构在软件中构建,并利用Ligprep模块在保持手性不变的前提下在PH=7±2范围内进行结构优化。对关键的氨基手动指定其质子化状态为带1各单位的正电荷。
对接计算采用XP精度。在对接中,每个化合物分子产生8000个构象,将前1000个优势构象进行能量优化并重新评估。将非极性氢原子的半径缩小为标准值的80%以获得更多的输出构象类型。综合考虑分子对接所提供的信息,包括化合物与DPP-4活性口袋中关键氨基酸残基的作用、与口袋形状契合程度以及疏水基团伸出口袋外部的特征等,选择了部分化合物分子进行化学合成和生物学检测。新合成化合物分子的生物活性测试结果表明,当计算打分函数Gsocre优于-10kcal/mol时,化合物将具有抑制DPP-4活性能力。下表中列出了计算打分函数Gsocre优于-10kcal/mol的化合物,但本申请不限于这些化合物分子。
生物学评价
1.本发明中部分化合物对DPP-4的抑制活性测定
本发明使用人结肠癌细胞株Caco-2的细胞裂解液作为DPP-4酶的来源(Thomas,L.,M.Eckardt,et al,The Journal of Pharmacology and Experimental Therapeutics325(1):175-182,2008)。在96孔板100μL/孔的筛药体系中,H-Gly-Pro-AMC底物(AnaSpec)的终浓度为0.1mg/ml,加入不同浓度的待测化合物37℃孵育30min后,以激发波长380nm/发射波长460nm检测荧光信号强度。根据检测获得的荧光值计算受试样品对DPP-4的酶活抑制率(%),并将酶活性抑制率达到50%时的浓度定为该化合物作用的IC50值。抑制率(%)根据下式进行:
抑制率%=(RFU空白-RFU化合物)/(RFU空白-RFU阴性对照)X100%
RFU化合物、RFU空白和RFU阴性对照分别表示化合物孔、空白孔和不加酶的阴性对照孔30min与0min的荧光值之差
经过以上方法检测DPP-4酶活,结果显示多个化合物对DPP-4有不同程度的抑制活性,其中实施例5化合物的活性较好,对DPP-4的抑制活性的IC50值为19.9nM;以上市DPP-4抑制剂Sitagliptin作为阳性对照,在该平台上测得的阳性药IC50为34.1nM,与文献值接近(Kim,D.,L.Wang,et al.J.Med.Chem48(1):141-151.2005)。
本发明的化合物对DPP-4的抑制活性的测试结果列在表1中。
表1:化合物各浓度对DPP-4抑制率(%)a
a实验结果(抑制率)用(平均值±标准差)表示(n≥2)
2.实施例5化合物对DPP-8和DPP-9的选择性测定
DPP-8、DPP-9与DPP-4同属于丝氨酸蛋白酶家族,DPP-8和DPP-9的抑制会引起多器官毒性和严重的免疫毒性(Lankas,G.R.,B.Leiting,et al.Diabetes54:2988-2994.2005),所以DPP-4抑制剂的选择性非常重要。人重组DPP-8酶购自abcam,人重组DPP-9酶购自R&D Systems。在96孔板100μL/孔的筛药体系中,H-Gly-Pro-AMC底物的终浓度为0.1mg/ml,加入不同浓度的待测化合物37℃孵育30min后,以激发波长(EX)380nm/发射波长(EM)460nm检测荧光信号。根据体系的荧光值计算受试样品对DPP-8和DPP-9的抑制率(%),并将酶活性抑制率达到50%时的浓度定为该化合物作用的IC50值。抑制率(%)根据下式进行:
抑制率%=(RFU空白-RFU化合物)/(RFU空白-RFU阴性对照)X100%
RFU化合物、RFU空白和RFU阴性对照分别表示化合物孔、空白孔和不加酶的阴性对照孔30min与0min的荧光值之差。
以Sitagliptin作为阳性对照,化合物对DPP-8/9的IC50与对DPP-4的IC50之比比较化合物之间选择性。
实验结果见表2和表3,表2为实施例5化合物和Sitagliptin对DPP-8和DPP-9的抑制活性的IC50,如表3所示,实施例5化合物对于DPP-8的抑制活性的IC50与DPP-4的IC50之比约为3296倍,对于DPP-9的抑制活性的IC50与DPP-4的IC50之比大于5000倍而阳性药Sitagliptin相应的分别仅有约1139倍和大于2900倍,说明实施例5化合物比阳性药Sitagliptin具有更好的选择性。

表3:小分子抑制剂对DDP8和DPP-9的选择性倍数
3.实施例5化合物(代号TPN6573)改善C57BLKS/J小鼠口服糖耐量水平
6-8周龄雄性C57BLKS/J小鼠按上海药物研究所SPF级动物饲养标准操作规程饲养。小鼠随机分组,每组6-8只,测量体重,禁食12h后,尾静脉取血,利用罗氏血糖仪及血糖试纸测空腹血糖水平。
受试化合物按不同剂量灌胃给药,给药后60分钟,各组小鼠进行口服糖耐量实验(Oral glucose tolerance test,OGTT)。具体步骤为:化合物灌胃给药后60分钟,再次测定各组小鼠的血糖水平,同时灌胃给予5g/kg体重葡萄糖溶液,并计为0时间点,然后分别在20、40和80分钟,尾静脉取血测血糖水平,绘制OGTT曲线,计算曲线下面积,利用单因素方差分析计算各组差异。
对实施例5化合物(代号TPN6573)进行详细的浓度梯度实验,以Sitagliptin为阳性对照,得到实验结果如图1(a)和图1(b)所示,实施例5化合物(代号TPN6573)能够显著改善小鼠的葡萄糖耐受,在较低剂量下(1mg/kg)仍然有很强的体内活性。
4.实施例5化合物(代号TPN6573)单剂量C57BLKS/J小鼠急性毒性实验
6-8周龄雄性C57BLKS/J小鼠按上海药物研究所SPF级动物饲养标准操作规程饲养。小鼠随机分为2组,每组10只,测量体重,过夜禁食14h后,口服灌胃给药2000mg/kg的实施例5化合物(代号TPN6573),和同等剂量的阳性药sitagliptin作为对照。观察两组小鼠的健康状况;两周之后摘眼球取血,检测丙氨酸转移酶(ALT)和天门冬氨酸转移酶(AST)活性。
两周内两组小鼠并无死亡,进食和饮水都没有明显的异常。测量ALT和AST的结果如图2(a)和图2(b)所示:实验结果表明,与阳性药sitagliptin相比,实施例5化合物(代号TPN6573)并没有明显的毒性。
