Phellodendrine has the effect of suppressing cellular immune response, reducing blood pressure and antinephritis, it also has antioxidant, and anti-inflammatory effects. Phellodendrine can suppress local semisyngeneic GvH reactions and systemic allogeneic GvH reactions in X-ray irradiated recipient mice, it also can suppress the induction phase of sheep red blood cell (SRBC)-induced delayed type hypersensitivity in mice and tuberculin-induced delayed type hypersensitivity in guinea pigs, Phellodendrine can down-regulating AKT, IKK, NF-kB phosphorylation and COX-2 expression induced by AAPH, it also ameliorates the ROS-mediated inflammatory response.
