Biological Activity of Forsythoside A

Description

Forsythoside A possesses strong antibacterial, antiinflammatory, antioxidant and antiviral effects. it has the potential to prevent IBV infection in vitro, it can promote the expression of IFN-α and Mx1 significantly.Forsythoside A has inductive effects on the activities of CYP1A2 and CYP2C11, without affecting CYP2D1 and CYP3A1/2 activities.

Targets

Antifection | P450 (e.g. CYP17) | P-gp

In vitro

Forsythoside a inhibits the avian infectious bronchitis virus in cell culture.[Pubmed: 20677175]

Phytother Res. 2011 Mar;25(3):338-42.

Forsythoside A is a polyphenolic constituent of the fruits of Forsythia suspensa Vahl. which is widely used as an antiinflammatory agent in traditional Chinese medicine.
METHODS AND RESULTS:
In the present study, the effects of Forsythoside A on cell infection by avian infectious bronchitis virus were assessed. A real-time fluorescence quantitative PCR assay was used to determine mRNA content of IBV N gene. The pretreatment of cells with Forsythoside A, adding Forsythoside A post infection of cells, and treatment of virus with Forsythoside A were analysed. The inhibitory effect of Forsythoside A was confirmed by infecting primary chicken embryo kidney cells. Infected cells were inhibited by Forsythoside A treatment.
CONCLUSIONS:
The data indicated that Forsythoside A has the potential to prevent IBV infection in vitro.

Effects of phillyrin and forsythoside A on rat cytochrome P450 activities in vivo and in vitro.[Pubmed: 27310729 ]

Xenobiotica. 2017 Apr;47(4):297-303.

1. Phillyrin and Forsythoside A are two important active ingredients in Forsythia suspensa. However, the effects of phillyrin and Forsythoside A on the activities of cytochrome P450 (CYP450) remain unclear.
METHODS AND RESULTS:
2. This study aimed to investigate the effects of phillyrin and Forsythoside A on the activities of CYP1A2, CYP2C11, CYP2D1 and CYP3A1/2 by cocktail probe drugs in rats both in vivo and in vitro. 3. Many pharmacokinetic parameters of caffeine and metoprolol in phillyrin pretreatment group, caffeine and tolbutamide in Forsythoside A pretreatment group were affected significantly. In rat liver microsomal incubation system, the concentrations of acetaminophen and dextrophan in the phillyrin pretreatment group are higher than blank control group by 207.69% and 125.00%, however, the concentrations of 4-hydroxytolbutamide and 6β-hydroxytestosterone were not significantly altered. The concentrations of acetaminophen and 4-hydroxytolbutamide in the Forsythoside A pretreatment group are higher than blank control group by 223.07% and 154.16%, whereas the concentrations of dextrophan and 6β-hydroxytestosterone were not significantly altered.
CONCLUSIONS:
4. These results indicated that Phillyrin had potential inductive effects on rat CYP1A2 and CYP2D1 activities, without affecting CYP2C11 and CYP3A1/2 activities. Moreover, Forsythoside A had inductive effects on the activities of CYP1A2 and CYP2C11, without affecting CYP2D1 and CYP3A1/2 activities.

Cell Research

Improvement of intestinal absorption of forsythoside A in weeping forsythia extract by various absorption enhancers based on tight junctions.[Pubmed: 23089157]

Phytomedicine. 2012 Dec 15;20(1):47-58.

Forsythoside A (FTA), one of the main active ingredients in weeping forsythia extract, possesses strong antibacterial, antioxidant and antiviral effects, and its content was about 8% of totally, higher largely than that of other ingredients, but the absolute bioavailability orally was approximately 0.5%, which is significant low influencing clinical efficacies of its oral preparations. In the present study, in vitro Caco-2 cell, in situ single-pass intestinal perfusion and in vivo pharmacokinetics study were performed to investigate the effects of absorption enhancers based on tight junctions: sodium caprate and water-soluble chitosan on the intestinal absorption of FTA, and the eventual mucosal epithelial damage resulted from absorption enhancers was evaluated by MTT test, measurement of total amount of protein and the activity of LDH and morphology observation, respectively. The pharmacological effects such as antioxidant activity improvement by absorption enhancers were verified by PC12 cell damage inhibition rate after H?O? insults. The observations from in vitro Caco-2 cell showed that the absorption of FTA in weeping forsythia extract could be improved by absorption enhancers. Meanwhile, the absorption enhancing effect of water-soluble chitosan may be almost saturable up to 0.0032% (w/v), and sodium caprate at concentrations up to 0.64 mg/ml was safe for the Caco-2 cells, but water-soluble chitosan at different concentrations was all safe for these cells.
