Active constituents research of bear bile targeting orphan nuclear receptor TR3

Abstract

熊胆作为传统名贵中药在中国已有上千年的历史,其临床药理作用毋庸置疑。然而, 过去由于科学研究水平低下,生产工艺条件落后,人们普遍采用杀熊取胆的方式来获取熊胆,导致熊胆资源短缺,其化学成分研究并不系统,其中活性成分及其活性机理的研究更加缺乏。本文充分结合天然产物化学研究及张晓坤教授在TR3孤儿核受体与癌症关系方面的独特优势,对熊胆具有核受体调控作用的活性成分进行了前期初步研究。结果发现,熊胆中含有可以明确上调TR3mRNA表达的活性成分,且熊胆主要化学成分TUDCA并不明显具有这种功能。这说明熊胆中可能含有其他对孤儿核受体TR3具有调控作用的活性成分,这为本课题的进一步深入研究提供了方向和思路...Bear bile has been used as a traditional Chinese medicine for thousands of years in China, with many proven beneficial effects in human. However, it has been difficulty to obtain a significant amount of bear bile, which has limited our identification of the active ingredients in bear bile and the investigation of their mechanism of action. Thus, the identification of the active components of bear ...学位:理学硕士院系专业:生物医学研究院_化学生物学学号:2052007115097
