This in vivo effect was comparable with that of the nonsteroidal anti-inflammatory drug aspirin. The seed preparation, in a concentration-dependent manner, reduced the mRNA levels of inflammation-related genes such as the inducible forms of cyclooxygenase and nitric-oxide synthase and the proinflammatory cytokine interleukin in lipopolysaccharide-stimulated mouse macrophage cell line RAW 264.7. Activity of the seed preparation was similar to that of the synthetic PEITC. PEITC was the most active of five different forms of isothiocyanate tested for their effects on in vitro proinflammatory gene expression. In vitro activity of the seed preparation was also compared with that of two known anti-inflammatory drugs. We conclude that Barbarea verna seed preparation may function as a potent anti-inflammatory agent, interfering with the transcription of proinflammatory genes.
