Descriptions:
1,5-Dicaffeoylquinic acid (1,5-DQA), a caffeoylquinic acid derivative isolated from Aster scaber, has neuroprotective effects, can prevent Aβ(42)-induced neurotoxicity through the activation of PI3K/Akt followed by the stimulation of Trk A, then the inhibition of GSK3β as well as the modulation of Bcl-2/Bax.[1]
1,5-Dicaffeoylquinic acid has antioxidant activity, and is stronger than that of ascorbic acid.[2]
1,5-Dicaffeoylquinic Acid has protective effects against MPP~+ induces neurotoxicity of PC12 Cells, it (50 μmol/L) pretreatment can inhibit the MPP+-induced up-regulation of the expression of α-synuclein mRNA and protein.[3]
1, 5-Dicaffeoylquinic acid can mediate glutathione synthesis through activation of Nrf2 protects against OGD/reperfusion-induced oxidative stress in astrocytes.[4]
