Alpha-cyperone, a major active compound of Cyperus rotundus, has anti-inflammatory effects with the down-regulation of COX-2 and IL-6 via the negative regulation of the NFκB pathway in LPS-stimulated RAW 264.7 cells.[1]
In the presence of subinhibitory concentrations of alpha-cyperone, Hla production was markedly inhibited,   and alpha-cyperone protects lung cells from Hla-induced injury , indicate that alpha-cyperone is a promising inhibitor of Hla production by S. aureus and protects lung cells from this bacterium, it may provide the basis for a new strategy to combat S. aureus pneumonia.[2]
Alpha-cyperone inhibits the expression of inflammatory and coagulant mediators via mitogen-activated protein kinase (MAPKs) and NF-kappa B signaling pathways, it may contribute to future research on the action mechanisms , as well as therapy for inflammation- or coagulation-related diseases.[3]
