Description
Curvularin is a macrocyclic lactone metabolite produced in several fungi. In a model of transgenic DBA/1 mice curvularin significantly reduced the expression of proinflammatory genes involved in the pathogenesis of collagen-induced arthritis and rheumatoid arthritis. In another study using human epithelial alveolar cell line A549/8 as the model, curvularin was shown to inhibit the cytokine-mixture-induced inducible-nitric-oxide-synthase promoter activity in a dose-dependent manner.
