Pinoresinol (Standard) is a reference standard for research and analysis in studies involving Pinoresinol. Pinoresinol ((+)-Pinoresinol) has antiinflammatory, hepatoprotective, and fungicidal activities, it can protect pial microcirculation from I-reperfusion injury, to increase nitric oxide release and to reduce oxidative stress preserving pial blood flow distribution; it may exert pharmacologically interesting effects via modulation of the insulin-like signalling pathway in C.elegans. Pinoresinol causes an upregulation of the CDK inhibitor p21(WAF1/Cip1) both at mRNA and protein levels, inhibits NF-kappaB and activating protein 1 (AP-1).
