How to use

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].

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].
