Licarin A ((+)-Licarin A), a neolignan, significantly and dose-dependently reduces TNF-α production (IC 50 =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. 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. Licarin A 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
