Abstract

涉及作为糖原磷酸化酶抑制剂的式(I)苯并嗪-4-酮化合物、其制备方法及其用于治疗和/或预防与糖原代谢异常相关的疾病的药物中的用途。

Description

苯并嗪-4-酮类化合物、其制备方法及医药用途 技术领域
本发明涉及药物化学领域,具体涉及作为糖原磷酸化酶抑制剂的苯并嗪-4-酮化合物、其制备方法及医药用途。
背景技术
肝脏是禁食状态下调节血糖的重要器官。据估算,在禁食过夜之后,74%的空腹血糖来源于肝脏的糖原分解,其余的来源于肝脏的糖异生。在2型糖尿病患者中,肝脏葡萄糖的生成速率显著增加,肝脏葡萄糖产生偏高。因此,抑制肝脏葡萄糖生成已成为研制新型抗糖尿病药物的重要靶标之一。
目前在临床上,二甲双胍这一临床上首选的降糖药,被认为主要是通过抑制肝脏糖异生作用来降低血糖;而在糖原降解领域,尚无有效的作用药物。而对于那些空腹血糖>14mg/dl(7.8mM)的2型糖尿病患者,抑制肝脏糖原降解,从而降低其肝糖输出,有助于降低其空腹血糖。
糖原磷酸化酶(glycogen phosphorylase)是催化糖原降解(glycogenolysis)的关键酶,该酶催化糖原的磷酸解,产生的葡萄糖-1-磷酸在磷酸葡萄糖变位酶的催化下转变成葡萄糖-6-磷酸,后者在葡萄糖-6-磷酸酶催化下生成葡萄糖,血糖升高。仍然需要能够抑制糖原磷酸化酶,从而抑制肝脏糖原降解的药物。

实施例14 对高脂饲料诱导的2型糖尿病肥胖小鼠(DIO)的降糖实验
4周龄雄性C57 BL/6J小鼠适应性喂养5天后,随机选择10只小鼠为正常对照组,饲以低脂饲料,其余小鼠饲以高脂饲料。小鼠每5只一笼,自由进食和饮水,明暗周期为12h,室温22℃~26℃。小鼠连续喂养12周后,测定空腹和葡萄糖耐量评价胰岛素抵抗,显示造模成功。按照体重将高脂饲养组按照10只/组,随机均分以下各试验组:模型对照组,二甲双胍组(400mg/kg,灌胃)和实施例8化合物组(高、中、低剂量组分别为50、25、12.5mg/kg,灌胃,每天1次)。按实验分组连续给药4周,末次给药前禁食过夜。
模型对照组在给药第0、7、14、21、27天的血糖值显著高于正常对照组( ##p<0.01)。二甲双胍400mg/kg组在给药第7、21、27天血糖出现显著性差异,低于模型对照组( **p<0.01);本发明实施例8化合物50mg/kg组在给药第7、14、21、27天血糖值均显著低于模型对照组( *p<0.05, **p<0.01),25mg/kg、12.5mg/kg组均在给药第21、27天血糖值显著低于模型对照组( **p<0.01)。

实施例15 对小鼠心肌缺血/再灌注(I/R)的保护作用
8周龄SPF级C57 BL/6J小鼠,体重20-25g,随机均分以下各试验组,10只/组:假手术组(Sham),I/R模型组(I.R Model)和实施例8化合物组高剂量组(HD 100mg/kg)、中剂量组(MD 50mg/kg)和低剂量组(LD 30mg/kg)。异氟烷麻醉小鼠,观察其无翻正反应后,使其仰卧位固定在手术操作板上。将小鼠胸前手术部位用75%酒精进行体表消毒,沿第3、4肋间剪开约1cm的切口,钝性分离胸大肌、胸小肌,持弯止血钳穿透肋间肌深入胸腔,借助其力量,迅速将心脏从肋间挤压出来。缝合针结扎其左前降支冠状动脉,造成小鼠心肌缺血,此刻可观察到左心室前壁变成苍白色。结扎后将心脏快速送回胸腔复位,将结扎活结线头暴露出体外,缝合针缝合皮肤切口。结扎的瞬间开始计时,缺血30min后,用手轻拉结扎线头,松开此结,恢复心脏供血,将小鼠放于37℃保温垫上至其恢复自动爬行能力。恢复心脏供血24小时后,I/R模型建立。实施例8化合物高、中、低剂量组经I/R造模后尾静脉注射给药,每天1次,连续给药7天。
暴露小鼠胸部,用医用棉签蘸取适量实验动物专用脱毛膏,均匀涂于小鼠胸颈部皮肤,用湿润的纸巾擦拭干净鼠毛,暴露心脏超声部位。选用小鼠专用超声探头(MS-400),麻醉小鼠,将其胸部朝上固定于手术操作板上,胸前均匀涂抹超声专用耦合剂,探头平放于小鼠胸腔中部,微调探头,大约逆时针旋转30°,通过B-mode模式观察清晰心脏的胸骨旁长轴切面,保存画面。再切换到M-mode模式,记录左心室直径最大处影像。通过分析软件处理数据,计算小鼠左心室的射血分数(EF),短轴缩短率(FS),舒张末容积(EDV)和收缩末容积(ESV)。结果发现,实施例8化合物在50-100mg/kg剂量处理下,显著改善I/R小鼠心脏的射血分数,缩短轴短率,恢复左心室的收缩和舒张末期容积,显著改善小鼠心脏功能。
注:LVEF:左室射血分数(Left Ventricular Ejection Fractions),是指:每搏输出量占心室舒张末期容积量的百分比。心室收缩时并不能将心室的血液全部射入动脉,正常成人静息状态下,心室舒张期的容积:左心室约为125mL,右心室约为137mL,博出量为60-80mL,即射血完毕时心室尚有一定量的余血,把博出量占心室舒张期容积的百分比称为射血分数,一般50%以上属于正常范围,人体安静时的射血分数约为55%~65%。射血分数与心肌的收缩能力有关,心肌收缩能力越强,则每搏输出量越多,射血分数也越大。正常情况下左室射血分数为≥50%;右心室射血分数为≥40%。若小于此值即为心功能不全。
LVFS:左室短轴缩短率(Left Ventricular Fractional shortening),是指:左心室舒张末期的内径减去左心室收缩末期内径,比上左心室舒张末期内径的百分比,这个值反映的是心脏的收缩和舒张功能。
LVEDV:左室舒张末期容积(Left VentricularEnd-diastolic volume),如字面意思,是指左室舒张末期心室内的容积,用于计算LVEF和LVFS。
LVESV:左室收缩末期容积(Left VentricularEnd-systolic volume),如字面意思,是指左室收缩末期心室内的容积,用于计算LVEF和LVFS。
以上,对本发明的实施方式进行了说明。但是,本发明不限定于上述实施方式。凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
