HIDE SMILES / InChI
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. Pinocembrin 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 addition, pinocembrin can be used as neuroprotective against cerebral ischemic injury with a wide therapeutic time window, which may be attributed to its antiexcitotoxic effects.

Sample Use Guides

A double-blind, placebo-controlled, randomized study was carried out in 58 healthy subjects. Single ascending doses of pinocembrin (20-150 mg) were evaluated in 5 cohorts. Multi-dose was studied at pinocembrin 60 mg. Pinocembrin displayed linear plasma pharmacokinetics over the dose range, 20-150 mg and was well tolerated up to 120 mg day(-1) when administered intravenously to healthy adults.
Route of Administration: Intravenous
Pinocembrin (5 approximately 100 uM) induced relaxation in rat aortic rings pre-contracted with norepinephrine (NE, 1 uM) or KCl (60 mM), with pEC(50) value 4.37+/-0.02 and 4.52+/-0.04. Pretreatment with pinocembrin (30 or 50 uM) also inhibited contractile responses to NE and KCl.
