What is CYNARIN?

Description

1,5-Dicaffeoylquinic acid (1,5-DCQA) has been found in A. montana and is an HIV-1 integrase inhibitor and free radical scavenger. 1,5-DCQA inhibits HIV-1 integrase 3'' end processing, end joining, and disintegration with IC₅₀ values of 0.35, 0.56, and 0.84 μg/ml, respectively. It also inhibits HIV-1 replication in MT-2 T lymphoblastoid cells with an ED₅₀value of 2 μg/ml. 1,5-DCQA (0.25-1 μM) reduces the level of free radicals released from human polymorphonuclear (PMN) cells stimulated by N-formyl-Met-Leu-Phe (fMLP; ) in a dose-dependent manner. It also dose-dependently increases cell survival and glutathione (GSH) levels and decreases reactive oxygen species (ROS) production and lactate dehydrogenase (LDH) release in an oxygen-glucose deprivation/reperfusion assay in rat cerebral astrocytes when used at concentrations ranging from 5 to 100 μM.

The Uses of CYNARIN

1,5-Dicaffeoylquinic Acid acts as an anti-hyperlipidemic agent. In addition, acts as a neuroprotective agent against amyloid-β toxicity in the treatement of Alzheimer’s.
