This compound acts directly as an inhibitor of the transcription factor kappa B-lymphocyte antibody (NF-kB), which serves to immune cells to the synthesis of many cytokines involved in inflammation. Furthermore it has the advantage of also directly inhibit 5-lipoxygenase, an enzyme that converts arachidonic acid in the known inflammatory mediators leukotrienes.
The parthenolide is very effective in eliminating, or at least in vitro models of tumor tissue transplanted into experimental animals, the proliferation of certain malignant cells from solid tumors that establishments (gastric cancer, lung, prostate and multiple myeloma, to name a few). Apart from its inhibitory effect on power factor NF-kB, as mentioned above, the alkylation parthenolide the enzyme DNA-cytosine methyltransferases (DNMT 1), amending the DNA leading to gene repression of many portions of chromatin. In practice, the parthenolide would act the same way as 5-azacytidine chemotherapy, used as an inducer of cell differentiation in the treatment of hematologic malignancies (multiple myeloma, myelodysplastic syndromes, etc.)..
