How to use

In Vitro:

Pinocembrin (5,7-dihydroxyflavanone) is one of the primary flavonoids isolated from the variety of plants, mainly from Pinus heartwood, Eucalyptus, Populus, Euphorbia, and Sparattosperma leucanthum, in the diverse flora and purified by various chromatographic techniques. Its vast range of pharmacological activities has been well researched including antimicrobial, anti-inflammatory, antioxidant, and anticancer activities. Pinocembrin has been shown to increase neuronal viability, decrease lactate dehydrogenase release, inhibit the production of NO and ROS, increase glutathione levels, and downregulate the expression of neuronal NO synthase (nNOS) and iNOS in primary cortical neurons subjected to oxygen-glucose deprivation/reoxygenation (OGD/R).

In Vivo:

Pinocembrin can be used as neuroprotective against cerebral ischemic injury with a wide therapeutic time window, which may be attributed to its antiexcitotoxic effects. It has the ability to reduce reactive oxygen species (ROS), protect the BBB, modulate mitochondrial function, and regulate apoptosis. Pinocembrin (10 mg/kg, i.v.) could reduce brain swelling; improve behavioral deficits; and alleviate neuronal apoptosis, edema of astrocytic end-feet, and the deformation of endothelial cells and capillaries. Pinocembrin reduces endoplasmic reticulum (ER) stress and apoptosis by decreasing C/EBP homologous protein (CHOP)/GADD153 and caspase-12 expression via the PERK-elF2α-ATF4 signaling pathway in MCAO rats. LD50 of i.v. pinocembrin in mice is greater than 700 mg/kg.
