Description

苄醇类化合物及其药物组合物与其应用
技术领域
本发明属于生物医药及化妆品领域。具体涉及一种具有抗菌作用的苄醇类化合物,以其为活性成分的药物组合物,它们的制备方法,及其在制备具用抗菌作用的药品、日用化学品、化妆品中的应用。
背景技术
天麻Gastrodiaelata Bl为兰科(Orchidaceae)天麻属多年生草本植物,又称赤箭、定风草、独摇芝,载于各版药典,是天麻药材的重要来源,主要分布于贵州、安徽、云南和湖北等省区,在日本、印度、尼泊尔、朝鲜半岛至西伯利亚也有分布。天麻主要含有菧类、菲类、多酚、生物碱、多糖等化学成分,具有抗惊厥、改善学习记忆,心脑血管和神经保护等方面的作用。
天麻是我国常用名贵中药材,主杀鬼精物、蛊毒恶气,久服益气力、长阴肥健、轻身增年功效。天麻作为传统中药可以用于治疗头风头痛,肢体麻木,小儿惊风等,其根茎入药已有悠久历史,但其地上部分茎秆长久以来被视为废材,弃之不用,对其化学成分研究较少,生物活性被忽视,造成资源浪费的现象。
耐药菌株是指经过长期的抗生素选择之后出现的对相应抗生素产生耐受能力的菌株。近年来由于临床治疗手段快速发展,抗生素药物广泛及不合理的使用,细菌耐药性的不断增强,导致临床治疗的失败,感染的复发,增加死亡的危险性等。在面对耐药菌的不断进化过程中,加强耐药菌株的监测,严格实施感染控制和合理应用药物是十分重要的一个方面,从结构丰富、生物活性多样的天然产物中寻找新的抗菌药物,也是当前人们的迫切需求。植物来源的天然产物以其特有的骨架结构及生理活性,为新药研发提供了丰富的先导化合物和候选药物来源,一直是药物研究的热点。
现有技术中未见有一种具有抗菌作用的苄醇类化合物在制备具用抗菌作用的药品、日用化学品、化妆品中的应用的报道。文献中均未涉及天麻提取物及苄醇类化合物具有抗菌的作用,也未提及将其作为功能添加剂加入化妆品中。
发明内容
本发明的目的在于提供一种具有抗菌作用的苄醇类化合物,以其为活性成分的药物组合物,及其在制备具用抗菌作用的药品、日用化学品、化妆品中的应用的报道。
经本发明人研究发现,苄醇类化合物对临床常见革兰氏阳性致病菌具有抑制作用,对耐万古霉素屎肠球菌(VRE)和耐甲氧西林金黄色葡萄球菌(MRSA)也具有抑制作用,这是目前临床常用的头孢类抗生素所不具有的特质。本发明首次提出苄醇类化合物对多株常见革兰氏阳性临床致病菌,尤其是对耐药菌株—耐万古霉素屎肠球菌(VRE)和耐甲氧西林金黄色葡萄球菌(MRSA)有抑制作用,适用于具有抗菌功效的药品,日化用品及化妆品中。
为了实现本发明的上述目的,本发明提供了如下的技术方案:
如下结构式所示的苄醇类化合物2,

药物组合物,其中含有苄醇类化合物2和药学上可接受的载体。
化妆品,由苄醇类化合物2和化妆品常用载体组成。
如下结构式所示的苄醇类化合物1或/和2在制备抗菌药物中的应用,
Figure BDA0002090856210000031
苄醇类化合物1和/或2在制备日用化学品或化妆品中的应用。
苄醇类化合物1和2的制备方法,该方法包括下述步骤:干燥天麻地上部分粉碎后,乙醇室温浸泡3次,减压浓缩浸膏溶于水,依次用乙酸乙酯与正丁醇萃取,分别得乙酸乙酯部分和正丁醇部分活性部位萃取物,乙酸乙酯部分溶解,吸附于400g硅胶,200-300目,湿法上样,经硅胶柱层析二氯甲烷-甲醇系统梯度洗脱200:1-0:1,经TLC检测,合并为6个组分Fr.1-6;Fr.4经正相硅胶柱,MCI洗脱,Fr.4.1经Sephadex LH-20洗脱得Fr.4.1.3,经HPLC制备,得抗菌活性苄醇类化合物2;Fr.5经正相硅胶柱,RP-8洗脱得Fr.5.6,再经Sephadex LH-20洗脱,得抗菌活性苄醇类化合物1。
本发明对天麻提取物利用多种色谱方法(正相硅胶、反相硅胶、凝胶、MCI柱层析及中压制备色谱MPLC和高效液相色谱HPLC)分离纯化得到7个化合物,通过多种波谱分析方法(NMR,MS,IR,UV)与文献对照鉴定其结构,包括1个新化合物。其中苄醇类化合物2结构如下:
