Biological Activity

Description Astilbin (Isoastilbin, Neoastilbin, Neoisoastilbin, Taxifolin 3-O-rhamnoside), a flavonoid compound isolated from the rhizome of Smilax glabra Roxb, displays anticancer, antioxidative, anti-inflammatory, and immunosuppressive activities.
In vitro
In vitro In vitro, astilbin inhibits Th17 cell differentiation and IL-17 secretion of isolated T cells, and inhibits Jak/Stat3 signaling in Th17 cells, while up-regulating Stat3 inhibitor SCOSE3 expression in psoriatic lesions. Astilbin has been reported to possess multiple clinically relevant bioactivities, including antioxidant, anti-inflammatory, anti-arthritic, and anti-diabetic nephropathy properties. Nevertheless, the molecular mechanisms by which astilbin interacts with inflammatory processes are poorly understood. Astilbin not only inhibits T lymphocyte function in acute heart allograft rejection, but also inhibits migration and antigen presenting of dendritic cells (DCs)[1].
Cell Research Cell lines CD4+ T cells
Concentrations 0-100 μg/ml
Incubation Time 3 days
Method Cell viability is assessed using the Cell Counting Kit-8 (CCK8) assay at 3 days after induction of Th17 differentiation. The mean optical density (OD) of the three wells in each group is used to calculate the percentage of cell proliferation.
In Vivo
In vivo Astilbin is reported to reduce activation of both T and B cells in lupus-prone mice. It significantly inhibits inflammatory responses and keratinocyte over-proliferation in a mouse model of imiquimod (IMQ)-induced psoriasis[1]. Astilbin undergoes extensive biotransformation specifically due to enzyme catechol-O-methyl transferase. It gives rise to 3′-O-methylastilbin, a major metabolite of astilbin, which plays important role against the inhibition activated T lymphocytes. The pharmacokinetic parameters of astilbin followed by intragastric administration astilbin (40 mg/kg): Cmax=37.7±14.7 ng/mL, Tmax=25.8±34.3 min, t1/2=161.6±44.1 min[2].
Animal Research Animal Models BALB/c mice (male, 18 to 20 g, 8 week-old)
Dosages 25 to 50 mg/kg

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
