目的:基于网络药理学和分子对接方法,确定复方黄柏液治疗的Ⅲ度烧伤肉芽组织愈合的有效活性成分、关键靶点和潜在的药理学机制,并进行肉芽组织成纤维细胞的初步验证。方法:从公共数据库中药系统药理学分析平台(TCMSP)检索复方黄柏液组...目的:基于网络药理学和分子对接方法,确定复方黄柏液治疗的Ⅲ度烧伤肉芽组织愈合的有效活性成分、关键靶点和潜在的药理学机制,并进行肉芽组织成纤维细胞的初步验证。方法:从公共数据库中药系统药理学分析平台(TCMSP)检索复方黄柏液组成成分连翘、黄柏、金银花的有效成分和靶点;GeneCards、OMIM数据库检索“Ⅲ度烧伤”疾病相关靶点。通过生物信息学分析,包括蛋白质-蛋白质相互作用(Protein-proteininteraction,PPI)以及基因本体(Gene ontology,GO)和京都基因和基因组百科全书(Kyoto encyclopedia of genes and genomes,KEGG)分析,获得了关键的有效成分、核心靶点和相关信号通路;DiscoveryStudio分子对接分析有效成分化合物与靶蛋白的结合。0.5%的DMSO溶液处理的成纤维细胞记为对照组;槲皮素(40μmol/ml)处理的成纤维细胞记为槲皮素组。采用CCK8法、Transwell实验检测细胞增殖、迁移侵袭;WB试验检测细胞p-PI3K、p-Akt蛋白。结果:共筛选出74个有效成分,331个作用靶点,AKT1为潜在的治疗靶点,木犀草素、山柰酚、槲皮素、汉黄芩素、丹皮酚为潜在的候选药物。PI3K-AKT信号通路可能在复方黄柏液治疗Ⅲ度烧伤中发挥关键作用;分子对接表明槲皮素与AKT1结合最好。与对照组相比,槲皮素组成纤维细胞增殖、迁移侵袭均显著降低,p-PI3K、p-Akt蛋白表达也显著降低(P<0.05)。结论:复方黄柏液促进Ⅲ度烧伤患者肉芽组织形成的生物活性成分为槲皮素,潜在通路为PI3K-AKT信号通路,为复方黄柏液治疗Ⅲ度烧伤的研究提供了思路。展开更多
