NF- Activation by Compounds Found in Platycodon grandiflorum Extract

Compounds extracted from Platycodon grandiflorum were evaluated for an activation effect on nuclear factor-kappa B (NF-${\kappa}B$). In its active state, NF-${\kappa}B$ turns on the expression of genes related to cell proliferation or death. NF-${\kappa}B$ activators promote growth of neuron cells and can be used to control neurodegenerative diseases. The biological activity of P. grandiflorum extracts toward NF-${\kappa}B$ had not yet been studied. Although the biological activity of several compounds extracted from P. grandiflorum was evaluated, only three exhibited any significant activation effect on NF-${\kappa}B$.
