Biological Activity

Description Pinocembrin (Dihydrochrysin, Galangin flavanone, 5,7-Dihydroxyflavanone) is a major flavonoid molecule incorporated as multifunctional in the pharmaceutical industry. Its vast range of pharmacological activities has been well researched including antimicrobial, anti-inflammatory, antioxidant, and anticancer activities.
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[1]. 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)[2].

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[1]. 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[2].

Protocol (from reference)

Cell Research:

[4]

  • Cell lines: SH-SY5Y cells
  • Concentrations: 4, 8, 20 μM
  • Incubation Time: 1 h
  • Method:

    SH-SY5Y cells are maintained in DMEM containing 10% FBS, 100 units/mL penicillin, and 100 µg/mL streptomycin in a humidified atmosphere containing 5% CO2 at 37℃.  Cells are passaged by trypsinization every 3-5 days. Then cells are seeded at 1 × 104 cells per well into a 96-well plate and then incubated for 24 h at 37 °C in a humidified atmosphere containing 5% CO2. The entire medium is then replaced with fresh medium containing 1% FBS, and one of the compounds is pretreated for 1 h, followed by the addition of 2.0 µg/mL tunicamycin or 30 nM staurosporine. Nuclear staining assays are carried out after a further 24 h of incubation. Cell death is assessed.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
