6-ForMylindolo[3,2-b]carbazole Usage And Synthesis

Description

6-Formylindolo(3,2-b)carbazole (FICZ) (172922-91-7) is a very potent (Kd?= 0.07 nM) endogenous ligand for the aryl hydrocarbon receptor (AhR).1,2

Uses

6-Formylindolo[3,2-b]carbazole is a tryptophan photoproduct, suppresses pulmonary eosinophilia and Th2-type cytokine production in a mouse model of ovalbumin-induced allergic asthma.

Biochem/physiol Actions

FICZ is a potent high affinity ligand of the aryl hydrocarbon receptor (AhR), which is a ligand-activated transcription factor that activates the expression of aromatic hydrocarbon metabolizing enzyme genes such as the CYP1A1 gene and has also been shown to have multiple additional roles in cell-cycle regulation, development and maturation of many tissues, control of inflammation, and immune response. FICZ is a photoproduct of tryptophan and is believed to be an endogenous AhR ligand. It is extremely potent, with a Kd value of 0.07 nM.

storage

Store at -20°C
