[Caffeoyl phenylethanoid glycosides from Callicarpa kwangtungensis].[Pubmed:25095374]
Zhongguo Zhong Yao Za Zhi. 2014 May;39(9):1630-4.
Phytochemical investigation on the EtOH extract from the aerial part of Callicarpa kwangtungensis led to the isolation and characterization of 10 caffeoyl phenylethanoid glycosides, 2'-acetylacteoside (1), tubuloside E (2), acteoside (3), tubuloside B (4), isoacteoside (5), alyssonoside (6), 2'-acetylForsythoside B (7), brandioside (8), Forsythoside B (9), and poliumoside (10). Compound 4 was isolated from the plants of Verbenaceae,and 6 was obtained from the Callicarpa genus, for the first time, while compounds 1, 2, 5 and 7 were firstly reported from the plant.
Forsythoside B protects against experimental sepsis by modulating inflammatory factors.[Pubmed:22147417]
Phytother Res. 2012 Jul;26(7):981-7.
The present study investigated the effects of Forsythoside B on an experimental model of sepsis induced by caecal ligation and puncture (CLP) in rats and elucidated the potential mechanism in cultured RAW 264.7 cells. Results showed that Forsythoside B concentration-dependently down-regulated the levels of TNF-alpha, IL-6 and high-mobility group-box 1 protein (HMGB1) in lipopolysaccharide (LPS)-stimulated RAW264.7 cells, inhibited the IkappaB kinase (IKK) pathway and modulated nuclear factor (NF)- kappaB. Intravenous injection (i.v.) of Forsythoside B alone or plus Imipenem reduced serum levels of TNF-alpha, IL-6, HMGB1, triggering receptor expressed on myeloid cells (TREM-1) and endotoxin, while the serum level of IL-10 was up-regulated and myeloperoxidase (MPO) in lung, liver and small intestine was reduced. Meanwhile, i.v. of Forsythoside B alone or plus Imipenem reduced CLP-induced lethality in rats. These data indicated that the antisepsis effect of Forsythoside B is mediated by decreasing local and systemic levels of a wide spectrum of inflammatory mediators. Its antisepsis mechanism may be that Forsythoside B binds to LPS and reduces the biological activity of serum LPS, and inhibits NF-kappaB activition. Our studies enhance the case for the use of Forsythoside B in sepsis. Forsythoside B itself has promise as a therapy for the treatment of sepsis in humans.
Neuroprotective efficacy and therapeutic window of Forsythoside B: in a rat model of cerebral ischemia and reperfusion injury.[Pubmed:20470770]
Eur J Pharmacol. 2010 Aug 25;640(1-3):75-81.
The present study was to investigate the neuroprotective efficacy and mechanism of Forsythoside B. Male Sprague-Dawley rats were subjected to middle cerebral artery occlusion for 1 h followed by reperfusion for 23 h. Rats received an intravenous bolus injection of Forsythoside B at 15 min after reperfusion. The results showed that Forsythoside B at doses higher than 8 mg/kg produced a significant neuroprotective potential in cerebral ischemia and reperfusion rats. Forsythoside B (20 mg/kg) demonstrated significant neuroprotective activity even after delayed administration at 1 h, 3 h and 5 h after cerebral ischemia and reperfusion. Forsythoside B 20 mg/kg attenuated histopathological damage as demonstrated by smaller brain infarct size and brain edema, decreased cerebral Evans blue extravasation and myeloperoxidase (MPO) activity, inhibited cerebral phosphor-IkappaB-alpha and nuclear transcription factors kappaB (NF-kappaB) expression. Meanwhile, NF-kappaB expression with immunohistochemical staining was reduced, while circulating polymorphonuclear leukocytes was increased. All of these findings suggested that Forsythoside B exerted potent neuroprotective effects with a favorable therapeutic time-window, reduce of cerebral ischemia and reperfusion injury degree, attenuating blood-brain barrier (BBB) breakdown, and its protective effects may be due to inhibition of inflammatory response.
Cardioprotection with forsythoside B in rat myocardial ischemia-reperfusion injury: relation to inflammation response.[Pubmed:19959348]
Phytomedicine. 2010 Jul;17(8-9):635-9.
The present study was undertaken to examine the effect of Forsythoside B (FB) on rat myocardial ischemia-reperfusion (I/R) model and elucidate the potential mechanism. Left ventricular systolic pressure (LVSP) and +/-dp/dt(max) were detected. Blood samples were collected to determine serum levels of troponin T (Tn-T), TNF-alpha and IL-6. Hearts were harvested to assess histopathological change and infarct size, determine content of MDA, myeloperoxidase (MPO), SOD and GPx activities, analyze expression of high-mobility group box 1 (HMGB1), phosphor-I kappaB-alpha and phosphor-nuclear factor kappaB (NF-kappaB) in ischemic myocardial tissue by Western blot. Compared with control group, rats treatment with FB showed a significant recovery in myocardial function with improvement of LVSP and +/-dp/dt(max). The myocardial infarct volume, serum levels of Tn-T, TNF-alpha and IL-6, content of MDA and MPO activity in myocardial tissue were all reduced, protein expression of HMGB1, phosphor-I kappaB-alpha and phosphor-NF-kappaB were down-regulated, while attenuated the decrease of SOD and GPx activities. Besides, the infiltration of polymorph nuclear leukocytes (PMNs) and histopathological damages in myocardium were decreased in FB treated groups. These findings suggested that FB rescued cardiac function from I/R injury by limiting inflammation response and its antioxidant properties.
Description
Forsythoside B is a phenylethanoid glycoside isolated from the leaves of Lamiophlomis rotata Kudo, a Chinese folk medicinal plant for treating inflammatory diseases and promoting blood circulation. Forsythoside B could inhibit TNF-alpha, IL-6, IκB and modulate NF-κB.
