CDr10b inhibits the expression of cyclooxygenase-2 and inducible nitric oxide synthase induced by lipopolysaccharide

Abstract

The pathophysiological processes of inflammation can lead to a host of diseases, such as periodontitis, atherosclerosis, rheumatoid arthritis, and even cancer. The dysregulated inducible nitric oxide synthase ( iNOS) and cyclooxygenase-2 ( COX- 2) activation play important roles in the development of certain inflammatory diseases. Here, we investigated the effects of CDr10b which is originally developed for a microglia staining probe on inflammation, by modulating NF-kappa B activation and iNOS and COX-2 expression induced by lipopolysaccharide (LPS) in murine macrophages. The CDr10b suppressed NF-kappa B activation and iNOS and COX-2 expression induced by LPS. All the results suggest that CDr10b is a promising novel agent for the treatment of inflammatory diseases.
