Abstract
Septic shock and associated vascular hyporeactivity to vasoconstrictor agonists remain a major problem of critical care medicine. Here we report that glycyrrhetinic acid (GA), the active component of licorice, effectively restores vascular contractility in the model of lipopolysaccharide (LPS)-treated rat aorta. GA was as effective as the NO synthase inhibitor N(G)-nitroarginine methylester. GA did not affect the vascular NO levels (measured by EPR spin trapping) and relaxations to L-arginine in LPS-treated rings as well as relaxation to S-nitroso-N-acetylpenicillamine in control rings. Thus, GA may represent an interesting alternative to NO synthase inhibitors in sepsis-associated vascular dysfunction.
