Glycyrrhizic acid has anti-tumor, antiviral ,antiallergic, anti-inflammatory, immunoregulatory,anti-diabetic activities. It is a direct HMGB1(high mobility group box 1) inhibitor that inhibits HMGB1-dependent inflammatory molecule expression and oxidative stress; modulates P38 and P-JNK but not p-ERK signalling; Also inhibits 11 beta-hydroxysteroid dehydrogenase and monoamine oxidase (MAO). Glycyrrhizinic acid is a triterpenoid saponin that is the glucosiduronide derivative of 3beta-hydroxy-11-oxoolean-12-en-30-oic acid. It has a role as an EC 3.4.21.5 (thrombin) inhibitor and a plant metabolite. It is a glucosiduronic acid, a pentacyclic triterpenoid, a tricarboxylic acid, an enone and a triterpenoid saponin. It is a conjugate acid of a glycyrrhizinate(3-).

Forsythoside B inhibits inflammatory response, has antioxidant, antisepsis properties, and also has potent neuroprotective effects with a favorable therapeutic time-window, reduce of cerebral ischemia and reperfusion injury degree, attenuating blood-brain barrier (BBB) breakdown. Forsythoside B could inhibit TNF-alpha, IL-6, IκB and modulate NF-κB.
