Curvularin (S-curvularin) is a macrocyclic lactone with cytotoxic activity. Curvularin inhibits cell division as well as expression of human inducible nitric oxide synthase (iNOS), an enzyme critically involved in pro-inflammatory immune processes. Also was discovered that S-curvularin is an effective anti-inflammatory compound that may serve as a lead compound for the development of new drugs for the therapy of chronic inflammatory diseases, such as Rheumatoid Arthritis or inflammatory bowel disease. S-curvularin is an inhibitor of iNOS-dependent NO production, acting on the Janus tyrosine kinase-STAT pathway.

To analyze the effect of S-curvularin on human iNOS promoter activity, there was incubated A549/8 cells stably transfected with pNOSII(16)Luc with different concentrations of S-curvularin: 1–100 μg/ml, 3–340 μM. It was shown, S-curvularin inhibited the CM-induced iNOS promoter activity in A549/8-pNOSII(16)Luc cells in a concentration-dependent manner. To study the effect of S-curvularin on STAT1 activation, Western blots using an antibody that detects the tyrosine (Tyr701) phosphorylation of STAT1 (corresponds to STAT1 activation; were performed. Incubation of A549/8 for 5 min with cytokine mixture (CM) resulted in a marked enhancement of STAT1 tyrosine phosphorylation. Coincubation of CM-treated A549/8 cells with -curvularin (100 μM) significantly reduced this STAT1 tyrosine phosphorylation.
