青蒿素及其衍生物二氢青蒿素、蒿甲醚、蒿乙醚、青蒿琥酯在制药中的应用
技术领域
本发明涉及青蒿素及其衍生物二氢青蒿素、蒿甲醚、蒿乙醚、青蒿琥酯的用途,尤其涉及在制药领域中的用途。
背景技术
细菌感染是现在临床病人死亡的主要原因。机体感染时,细菌菌体成分如基因组DNA及细菌内毒素(LPS)通过激活哺乳动物单核/巨噬细胞、树突状细胞等多种免疫细胞,诱导TNF-α、IL-1、IL-6、NO等致炎细胞因子的释放,导致组织器官的损伤,引起脓毒症的发生。
青蒿属菊科植物,1972年我国科研人员最早从中药青蒿中分离得到抗疟有效单体,命名为青蒿素。青蒿素分子式为C15H22O5,根据化学反应,光谱数据和x-射线单品衍射方法,证明青蒿素是一种具有过氧基的新型倍半萜内酯。其衍生物主要有二氢青蒿素、蒿甲醚、蒿乙醚及青蒿琥酯的化学结构式为:
 
青蒿素及其衍生物用来治疗疟疾相关的发热已经有一千多年的历史,现在临床上主要用于耐药恶性疟疾。Efferth TM,Wang X,Huong SM,Hauber I等在其文章《Antiviral activity of artesunate towards wild-type,recombinantandganciclovir-resistant human cytomegalovimses》(J Mol Med.2002;80(4):p223-224)中描述了青蒿类物质还具有其它方面的作用,如平喘、抗癌、抗血吸虫及对免疫系统的调节等。国内外有关青蒿素及其衍生物的研究主要集中在抗疟、抗癌、抗血吸虫的作用及其机制上。
对青蒿素及其衍生物的抗内毒素的作用已有研究,Aldieri E,Bergandi L,RigantiC,Costamagna C,Bosia A,Ghigo D等在其文章《Artemisinin inhibits inducible nitricoxide synthase and nuclear factor NF-kB activation》(FEBS Lett.2003;552(2-3):p141-144)中描述了青蒿素可抑制LPS/TNF-α诱导性NO合酶的合成及NF-κB的激活;梁爱华,薛宝云,李春英等在其文章《青蒿琥酯对内毒素诱导的一氧化氮合成的抑制作用》(中国中药杂志.2001;26(11):p770-773.)中描述了青蒿素衍生物青蒿琥酯对LPS及合并干扰素刺激小鼠腹腔巨噬细胞NO的合成有明显的抑制作用,对LPS刺激的小鼠腹腔巨噬细胞RAW264.7也具有相似的保护作用,而且随着青蒿琥酯浓度的增加青蒿琥酯对NO合成的抑制作用也增强,梁爱华、薛宝云、王金华等在其文章《青蒿琥酯对内毒素诱导的炎症因子合成抑制作用的研究》(中国中西医结合急救杂志.2001;8(5):p262.-265)中描述了青蒿琥酯在25~100mg/L对LPS诱导的TNF-α产生具有明显的抑制作用,与LPS单独应用比较抑制率为43%~58%;谭余庆等在其文章《青蒿素提取物抗内毒素作用的实研究》(中国中药杂志.1999;24(3):p166-171)还发现青蒿提取物、青蒿素可降低内毒素休克小鼠LPO、ACP、内毒素、TNF-α、P450浓度,升高SOD活性,降低小鼠死亡率,延长小鼠的平均生存时间,对小鼠肝、肺组织形态也有一定的保护作用。但是青蒿素及其衍生物对细菌DNA以及细菌(革兰阳性菌和革兰阴性菌)导致的脓毒症是否有效,未见报道。
