10-Cl-BBQ is a high affinity AhR ligand with immunosuppressive activity. 10-Cl-BBQ promotes cytosol to nuclear translocation of AhR and activates the AhR-regulated reporter gene at nanomolar concentrations[1][2]. | [Biological Activity]
10-Cl-BBQ is an orally bioavailablenon-toxic benzimidazoisoquinoline derivative th at acts as an aryl hydrocarbon receptor (AhR) agonist via directly binding to AhR (IC50 = 2.6 nM in a competitive binding assay) and induces its nuclear translocation. 10-Cl-BBQ is shown to increase CD4+ T-cells th at co-express CD25CTLA-4 and ICOSas well as several other genes associated with regulatory T cell (Treg) function in a graft versus host response model (GVHC57BI/6 T cells injected into B6D2F1 host mice). 10-Cl-BBQ displays good pharmacokinetic profile in mice (t1/2 = 2 hCmax = 21.5 μg/L10 mg/kgi.p.). Also shown to prevent insulitis in a NOD T1D mouse model which is independent of Fox3 + Tregs (60 mg/kgp.oq.o.d.). | [storage]
