细胞膜固相色谱及其在中药效应-物质基础研究中的应用

Cyto-membrane Immobolized Chromatography:Hypothesis,Method and Application in Traditional Chinese Medicine

  • 摘要: 中药效应-物质基础的探讨较为困难,需要建立当代生物医学与中医学理论能够兼容的方法学对其进行解析。本实验室在国家科技部的资助下,对这一问题进行了探索,建立了细胞膜固相色谱技术。这一技术是基于细胞与内外环境的信息传递,主要通过包括药物在内的介质与细胞膜上的受体、离子通道、酶等各种信息靶点结合而实现的。我们利用这一原理,将细胞膜与中药提取液共温育,用色谱分析法解析被细胞膜特异性结合的成分。所建立的细胞膜固相色谱与一般生物色谱不同点在于:将细胞与中药提取物对话过程与色谱分析过程分开,分别满足各个过程的实验条件。这一技术在当归、丹参及脉络宁注射液效应-物质基础分析的研究中显示出应用前景。

     

    Abstract: A wide variety of molecules,including bormones,drugs,neurotransmitters,growth factors,antigens,viruses,plasma lipoproteins and glycoproteins,elicit their biological effects by virtue of their binding to cellular receptor.Many of these agents,however,interact with receptor or other target on external surface of the cell imbedded in cellular plasma membrane.Although in most circumstance,we still do not know correctly which substance are responsible for the effects of Traditional Chinese Medicine,and through which mechanism it works.But based the clinical response and pharmacological experimental phenomena,we believe that most Traditional Chinese Medicine's effect come from their compnents which interact with target of the organism.It is generally that noncovalent binding of drug to the target on the cell membrane may appear to be essentially reversible.Receptor and other target extend through the cell membrane.The part of the target on the exterior of the cell surface capture the signal components of TCM to be communicated to the cell in the outside environment.So our working hypothesis has been put forward as:The cell membrane of organism could be used as a material with which effective chemicals in Traditional Chinese Medicine could bind to the target that embedded on it.That is basis of cyto-membrane immobilized chromatography and it's application in Traditional Chinese Medicine.The cyto-membrane lmmoboliged chromatography is composed of the biologic membrane immobilized part and the chromatography part,The apavts have beon separatedin our wark,both parts have their optimal situation.This may be the creational in our work.The applications of red blood cell membrane immobilized chromatography in Angelica archangelica,platelet membrane immobilized chromatography in Salviae miltiorrhizae radix and Mailuoning Injection,a formula herbal injection for blood stasis,have been analyzed.The results shown that cyto-membrane immobilized chromatography are worked,although it is a pilot job.
