Licarin A ((+)-Licarin A), a neolignan, significantly and dose-dependently reduces TNF-α production (IC50=12.6 μM) in dinitrophenyl-human serum albumin (DNP-HSA)-stimulated RBL-2H3 cells. Anti-allergic effects. Licarin A reduces TNF-α and PGD2 production, and COX-2 expression[1]. | [Biological Activity]
Licarin A ((+)-Licarin A), which can be isolated from a variety of plants, significantly reduces dinitrophenylhydrazine-human serum albumin (DNP-HSA)-stimulated RBL-2H3 cells. It has anti-allergic effect and reduces TNF-α and PGD2 production, and COX-2 expression. | [in vitro]
Licarin A is found in plants such as Aristolochia taliscana , Machilus thunbergii and Myristica fragrans , which are used as spices and in folk medicines for nervous and digestive disorders. It also exhibits anti-inflammatory effects.
Licarin A (5-20 μM) reduces TNF-α and prostaglandin D2 (PGD2) secretion via the inhibition of PKCα/βII and p38 MAPK pathways. Licarin A treatment tends to reduce phosphorylated PKCα/βII and p38 MAPK protein levels. | [IC 50]
