ECH@FG超分子自组装纳米粒的构建及活性评价
Construction and activity evaluation of ECH@FG supramolecular self-assembled nanoparticles
构建了一种基于松果菊苷(ECH)和葡萄糖酸亚铁(FG)的超分子自组装纳米粒,直径为100 nm左右。采用透析袋法评估释药性能、采用ABTS和DPPH自由基清除实验评价抗氧化能力,通过谷氨酸诱导的HT22细胞模型及CCK-8法评估神经元保护作用。结果表明,该纳米粒释药表现出pH响应性、较强的抗氧化能力、良好的氧化损伤保护效果。综上,自组装纳米粒的构建使得ECH的生物活性显著提高。
A kind of supramolecular self-assembled nanoparticles with a diameter of about 100 nm is constructed on the basis of echinacoside and ferrous gluconate.The drug release performance of the nanoparticles is evaluated by using dialysis bag method,the antioxidant capacity is evaluated through ABTS and DPPH free radical scavenging experiments,and the neuronal protective effect is evaluated through HT22 cell oxidative damage model induced by glutamate and CCK-8 method.It is found that the nanoparticles show pH response,strong antioxidant ability and good protective effect against oxidative damage.In a sum,the bioactivity of echinacoside is significantly improved by constructing self-assembled nanoparticles.
