Parthenolide inhibits the growth of the promastigote form of L. amazonensis (IC50 = 3.6 μg/ml). Parthenolide also induces apoptosis in cancer cells, at least in part by inhibiting NF-κB- and STAT-mediated anti-apoptotic gene transcription. Parthenolide has also been shown to block inflammation by inhibiting signaling through NF-κB. Inhibition of NF-κB by parthenolide can be achieved by direct binding of the pattern recognition receptor NOD2 by parthenolide. COX-2 inhibition is the mechanism by which parthenolide induces cell death in the cancer stem-like cells of nasopharyngeal carcinoma. In addition, parthenolide exhibited an inhibitory effect on nuclear factor-kappa B (NF-κB) nucler translocation by suppressing both the phosphorylation of IκB kinase complex and IκBα degradation.
