Calyptranthes grandifolia O.Berg (Myrtaceae) ethanolic extract inhibits TNF-α gene expression and cytokine release in vitro.

Anti-tumor therapies based on anti-inflammatory effects have been considered in cancer treatment. Survival, proliferation and, resultantly, invasion and metastasis of tumor cells are regulated by local inflammatory mediators. Primary inflammatory cytokines, such as tumor necrosis factor (TNF), are targets for anticancer therapy.
