Description
技术领域
本发明属于生物医药领域,更具体地,涉及一种抗高血压活性肽Orn-Hyp-Pro及应用,和一种抗高血压的药物组合物。
背景技术
《中国心血管病报告2015》指出我国的心血管病患病率处于持续上升阶段。高血压是心血管疾病的主要危险因素已成共识,它是我国心血管疾病患病率持续上升的推动因素。2014年卫生部统计数据表明我国的高血压病患率为25.5%,一些省份达到27.9%,全国高血压患者数估计达2.7亿。
目前,许多抗高血压药物被认为是临床一线的治疗药物,其中血管紧张素转换酶抑制剂(ACEI)是临床效果最好的药物,如依那普利、卡托普利、苯那普利、赖诺普利、群多普利等。但它们仍然存在一定的副作用,如干咳、皮疹、血管性水肿和肾损伤等。
ACEI类药物是一类肽类和修饰氨基酸类物质,而天然的蛋白是丰富的肽资源。因此,科学家们一直致力采用酶水解和发酵的方式制备获得ACEI活性肽,以期使高血压患者得益。如两个具有抗高血压生物活性三肽“VPP”(Val-Pro-Pro,VPP)和“IPP”(Ile-Pro-Pro,IPP)被鉴定出来。但是,这种制备方式成本高、重复性低、生物利用率低,迫切需要发展一种新的替代生产技术。这些研究都是基于蛋白质中蕴含的肽信息,虽然随着肽分子量的增大,其结构将千差万别,活性亦将愈加具有潜力,但是由于肠道黏膜的分子筛效应和其富含的肽酶,制约了利用天然蛋白活性资源开发ACEI肽类小分子物质。因此,如何规避化学修饰肽类或氨基酸类ACEI小分子药物的副作用和避免体内肽酶的水解而完整吸收,成为开发安全无副作用的ACEI小分子药物研究热点。
发明内容
本发明的目的是提供一种抗高血压活性肽Orn-Hyp-Pro及应用和药物组合物。
本发明的第一方面是提供一种抗高血压活性肽Orn-Hyp-Pro,所述活性肽的氨基酸序列为:鸟氨酰-羟脯氨酰-脯氨酸,具有式I所示结构。简称为Orn-Hyp-Pro(Ornithine(Orn)-Hydroxyproline(Hyp)-Proline(Pro))。
本发明从定量构效关系(QSAR)出发,利用食源性稀有氨基酸,结合抗高血压活性肽C末端Pro耐受肽酶水解的构效特点,设计一系列小分子物质,通过CLC Drug DiscoveryWorkbench分析设计小分子物质和ACE的相互作用的化学特性,初步确定具有抗高血压的肽分子,通过液相合成法制备,进一步通过体外和体内生物活性验证,筛选确定具有较强抗高血压活性的合成肽。该抗高血压活性肽可通过本领域的常规方法制得,例如液相合成法。
本发明的第二方面提供所述的抗高血压活性肽Orn-Hyp-Pro在制备抗高血压的药品和食品中的应用。
本发明的第三方面提供一种抗高血压的药物组合物,包括有效成分和辅料,所述的有效成分包括所述的抗高血压活性肽Orn-Hyp-Pro。
根据本发明,所述辅料可以为常规的各种药用辅料或食品添加剂。
本发明与现有技术相比具有如下优势:
本发明提出了一种不同的活性肽。现有技术从天然蛋白中通过体外蛋白酶解或微生物发酵分离获得活性肽,可以被肠道黏膜中富含的肽酶进一步水解,降低了其体内实际作用。本发明的活性肽是由稀有氨基酸和常规氨基酸构成,在天然蛋白中并不存在这样序列构成。因此,本发明的活性肽可以逃避体内蛋白酶的进一步水解,保证了其吸收的完整性和体内作用的稳定性。
本发明活性肽的血管紧张素转换酶(ACE)活性抑制的IC50为326.72μmol/L,采用1.0mg/kg体重的剂量灌胃先天性高血压大鼠2小时后血压从212mmHg下降到最低点195mmHg,持续药效时间为2小时。
本发明的其它特征和优点将在随后具体实施方式部分予以详细说明。
附图说明
通过结合附图对本发明示例性实施方式进行更详细的描述,本发明的上述以及其它目的、特征和优势将变得更加明显。

在(2S)-2,5-双[(叔丁氧羰基)氨基]戊氨酰叔丁基羟脯氨酰脯氨酸(Boc-Orn(Boc)-Hyp(tbu)-Pro)中加入4N盐酸气/丙烯酸乙酯,溶解至澄清,室温搅拌反应2小时。在反应液中边搅拌边加入6-8倍体积的无水乙醚,进行层析、4000rpm离心3分钟。弃上清后用乙醚重复洗涤5次,析出得到白色固体物质进行真空干燥得到鸟氨酰羟脯氨酰脯氨酸三肽(Orn-Hyp-Pro)粗制品。

实施例2
体外血管紧张素转换酶(ACE)活性抑制试验。
马脲酰组氨酰亮氨酸(hippuryl-L-histidyl-L-leucine,HHL)在ACE酶的催化下快速分解产生马尿酸(Hippuric Acid,HA)和二肽histidyl-leucine(HL),加入ACE酶抑制剂后,ACE酶的活性受到抑制,HA和HL的生成量减少,本实施例中ACE通过兔肺提取,酶活力为0.76mU/mL,通过DAB显色,采用分光光度计法测定HA生成量,分析ACE酶活。乙酸乙酯提取反应物中的马尿酸,然后在乙酸酐中与含对二甲氨基苯甲醛的吡啶溶液(DAB显色剂)反应生成桔黄色的化合物,直接在459nm比色测定其OD值,按下列公式评价ACE酶抑制剂对ACE酶的抑制率。以50%的ACE酶活性受到抑制所需合成三肽的浓度(IC50)定义合成三肽的ACE抑制活性。

具体反应体系和条件见表1。
表1
本实施例方法测得本发明的活性三肽对ACE抑制活性IC50为326.72μmol/L。
实施例3
先天性高血压大鼠(SHR)体内降压试验。
采用SoftronBP-98A型大鼠智能无创血压仪,利用套尾法测定测定大鼠的收缩压(SBP)。
在SHR大鼠(自发性高血压大鼠)清醒状态下,首先将老鼠放在鼠袋中,保持恒温,采用SoftronBP-98A型大鼠智能无创血压仪进行套尾测定尾静脉血压的方法,测定大鼠的收缩压(SBP)。于实验前一周开始隔天测定大鼠的血压,待大鼠稳定适应后开始实验记录。先测定灌胃前的大鼠血压,然后1.0mg/kg体重剂量进行样品(实施例1的活性三肽,Orn-Hyp-Pro)灌胃,空白对照组灌胃等体积生理盐水(Saline),药物对照组灌胃10mg/kg体重的抗高血压药物卡托普利(captopril)连续进行血压监测4小时,样品灌胃后每30分钟连续记录大鼠血压。每个测试点均测定3次大鼠的血压,每次测定的间隔时间约1分钟,取3次测定值的平均值作为该测试点大鼠的血压,结果如图1所示。
图1为生理盐水对照组、抗高血压药物对照组和合成活性肽组大鼠灌胃给药后的血压变化情况,其测得数据用SPSS系统软件进行系统处理,采用t检验方法。由实验结果可知,与药物对照组相比,合成肽的降压效应比药物组迟滞30分钟左右,同时效应时间相对较短,大约为2小时。合成活性肽灌2小时后,SHR血压显著下降到最低点,在灌胃4小时后,血压回升到初始压值。说明本发明活性肽(Orn-Hyp-Pro)具有较好的降血压效果。
以上已经描述了本发明的各实施例,上述说明是示例性的,并非穷尽性的,并且也不限于所披露的各实施例。在不偏离所说明的各实施例的范围和精神的情况下,对于本技术领域的普通技术人员来说许多修改和变更都是显而易见的。
