Astilbin is a flavonoid compound that can enhance NRF2 activition with anti-inflammatory properties. It could be extracted from chinese astilbe. Astilbin has been found to have significant immunosuppressive effects in recent years.

How to use
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).
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. 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.
