Eupatorin is a natural flavonoid isolated from the herbs of Eupatorium semiserratum. It has the anti-inflammatory and anti-proliferative properties, which may be utilized in the development of novel anti-inflammatory and anti-tumor treatments. Eupatorin moderately inhibited human cytochrome P450 1A2 (CYP1A2). Eupatorin showed IC50 values of 0.4 ug/mL on T. cruzi epimastigotes and 61.8 ug/mL on trypomastigotes, respectively. It was demonstrated, that eupatorin exerts a vasorelaxative effect on aortic rings through the NO/sGC/cGMP and PGI2 pathways, calcium and potassium channels, muscarinic and beta-adrenergic receptors.
