|Syringin from stem bark of Fraxinus rhynchophylla protects Abeta(25-35)-induced toxicity in neuronal cells.[Pubmed: 20422361]|
|The medicinal herb Jinpi, derived from the dried stem barks of Fraxinus rhynchophylla belonging to Oleaceae is widely used as a variety of Korean folk remedies for anti-inflammatory, febricide, antidiarrhea, and antileukorrhea diseases.
METHODS AND RESULTS:
In the course of screening antidementia agents from natural products, F. rhynchophylla showed significant inhibitory activity toward Abeta(25-35)-induced neuronal cell death. An active principle was isolated and identified as Syringin.When the neuroblastoma cells were exposed to 50 microM Abeta(25-35), 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction rate (survival rate) decreased to 60.21 +/- 2.16% over control while Syringin treated ones recovered cell viability up to 79.12 +/- 1.39% at 20 microM. In addition, 20 microM Syringin almost completely removed Abeta(25-35)-induced reactive oxygen species. The neuroprotective effect of Syringin seemed to be originated from the reduction of apoptosis since decrease in caspase-3 activity and expression, reduction in cleaved PARP, and DNA fragmentation were observed.
These results suggest that F. rhynchophylla and Syringin are expected to be useful for preventing Abeta(25-35)-induced neuronal cell damage.

|Syringin may exert sleep-potentiating effects through the NOS/NO pathway.[Pubmed: 25377727]|
|Sleep is essential for basic survival as well as for optimal physical and cognitive performance in both human beings and animals.
METHODS AND RESULTS:
To investigate the effect of Syringin on sleep of anesthetized mice and the potential mechanisms, 35 male Kunming mice were randomly divided into six experimental groups (n = 5) and one control group (n = 5). Sleep latency and sleep duration, as well as nitric oxide (NO) content and nitric oxide synthase (NOS) activity, were determined after Syringin administration. The NO precursor l-Arginine (l-Arg) or NOS inhibitor NG-Nitro-l-arginine methyl ester (l-NAME) was administered alone or in combination with Syringin, and time for sleep latency and duration was recorded. After intragastric administration of Syringin, sleep latency decreased in a dose- and time-dependent manner, concomitant with increased sleep duration. The optimal sleep performance was obtained when Syringin was given at a dose of 80 mg/kg for eight consecutive days. Syringin significantly reduced NO concentration and NOS activity. Administration of l-Arg prolonged sleep latency and shortened sleep duration, and the effects were fully reversed by Syringin coadministration. Administration of L-NAME induced a significant reduction in sleep latency and a corresponding increase in sleep duration, and coadministration of Syringin further enhanced the effects.
The finding of our study demonstrated that Syringin could exert sleep-potentiating effects on anesthetized mice in a time- and dose-dependent manner, and these effects may be intimately correlated with the NO/NOS pathway.

|Anti-inflammatory and antinociceptive effects of sinapyl alcohol and its glucoside syringin.[Pubmed: 15549657]|
|In the present study, Syringin, isolated by activity-guided fractionation of the ethyl acetate (EtOAc) extracts of the stem bark of Magnolia sieboldii, and sinapyl alcohol, the hydrolysate of Syringin, were evaluated for anti-inflammatory and antinociceptive activities.
METHODS AND RESULTS:
Sinapyl alcohol (20, 30 mg/kg/day, p. o.) inhibited increased vascular permeability by acetic acid in mice and reduced acute paw edema by carrageenan in rats more so than Syringin. When analgesic activity was measured using the acetic acid-induced writhing test and the hot plate test, sinapyl alcohol was much more potent than Syringin in a mouse model. In addition, sinapyl alcohol more potently inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO), prostaglandin E2 (PGE2), and tumor necrosis factor (TNF)-alpha production by macrophages than Syringin. Consistent with these observations, the expression levels of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 was reduced by sinapyl alcohol in a concentration-dependent manner.
These results suggest that the anti-inflammatory and antinociceptive effects of Syringin after oral administration may be attributed to its in vivo transformation to sinapyl alcohol.
