alpha-Cyperone (Standard) is a reference standard for research and analysis in studies involving alpha-Cyperone. 1. alpha-Cyperone (α-Cyperone) is a promising inhibitor of Hla production by S. aureus and protects lung cells from this bacterium. 2. alpha-Cyperone significantly inhibited PGE2 production by suppressing the LPS-induced expression of inducible COX-2 at both the mRNA and the protein levels , downregulated the production and mRNA expression of the inflammatory cytokine IL-6. 3. alpha-Cyperone inhibited actin cytoskeleton polymerization induced by APEC-O78 through down regulating the expression of Nck-2, Cdc42 and Rac1.
