生物活性
3,4-Dicaffeoylquinic acid 是天然分離的，具有抗氧化，DNA 保護(hù)，神經(jīng)保護(hù)和肝保護(hù)特性。3,4-Dicaffeoylquinic acid 具有凋亡介導(dǎo)的細(xì)胞毒性和 α-葡萄糖苷酶 (α-glucosidase) 抑制作用。3,4-Dicaffeoylquinic acid 具有獨(dú)特的抗病毒作用機(jī)制，即通過增加 TRAIL 來提高病毒清除率。
靶點(diǎn)
Human Endogenous Metabolite
體外研究 3,4-Dicaffeoylquinic acid acts as a greater primary antioxidant than its methanol extract, by having higher ferric reducing activity (EC 50 2.18 μg/ml), β-carotene bleaching activity (EC 50 23.85 μg/ml) and DPPH scavenging activity (EC 50 68.91 μg/ml). 3,4-Dicaffeoylquinic acid exhibits a remarkable dose-dependent inhibitory effect on NCI-H23 (human lung adenocarcinoma) cell lines (EC 50 3.26 μg/ml) and is found to be apoptotic in nature based on a clear indication of DNA fragmentation. 3,4-Dicaffeoylquinic acid also displays a concentration-dependent α-glucosidase inhibition with EC 50 241.80 μg/ml.
