Screening and Mechanism Study of Neuroprotective Compounds from Microbial Natural Products and their derivatives

Abstract

帕金森症、阿尔茨海默病、亨廷顿氏舞蹈病等神经退行性疾病是一种以原发性神经元变性为基础的进行性慢性神经系统疾病,对中老年人的健康有严重的威胁。目前,临床上应用的抗神经退行性疾病药物大多是以改善临床症状为主,无法控制其病程进展,远不能满足治疗的需求。因此,创制抗神经退行性疾病新药对预防和治疗这类疾病具有重大意义。 本论文采用神经系统研究中常用的PC12细胞氧化损伤模型,对875种微生物来源的天然产物或其衍生物进行筛选,结果显示,在终浓度为10µg/mL时,有90种化合物能不同程度地提高H2O2诱导损伤的PC12细胞存活率,对氧化应激损伤细胞具有明显的保护活性,占供筛选化合物的10.2...Neurodegenerative diseases are a kind of primary neuronal degeneration, chronic progressive neurological diseases, which seriously threats to the health of the elderly. At present, the clinical application of anti-neurodegenerative diseases drugs is to improve the main clinical symptoms, and unable to control its progress, which can not meet the demand for treatment. Therefore it means great signi...学位:理学硕士院系专业:生命科学学院_微生物学学号:2162010115237
