Our results suggest that bisacurone exhibits anti-inflammatory effects by inhibiting the NF-κB pathway, which is consistent with a previous study reporting the inhibitory properties of 18 types of bisabolane-type sesquiterpenoids extracted from turmeric, including bisacurone C (an isomer of bisacurone used in this study) on the expression of TNF-α, IL-6, and IL-8, at mRNA and protein levels in A549 cells, a human lung carcinoma with properties of type II alveolar epithelial cells [27]. Here, TNF is linked to lung carcinoma.
