Sakuranetin (SK) is a flavonoid widely found in Baccharis retusa plant and presents anti-inflammatory and antioxidant effects. This study evaluates the effects of preventive and therapeutic SK treatment in a model of ALI. Mice received intratracheal LPS or saline and were evaluated after 6 or 24hs to determine if lung inflammation is already present in 6hs. Animals were then treated with vehicle (LPS_VE) or SK 30min before (SK30'_LPS) or 6hs (LPS_SK6h) after LPS instillation. The bronchoalveolar lavage (BALF) and peripheral blood, exhaled nitric oxide (ENO) and the percentage of collagen fibers in alveolar septa were evaluated 24 hs after. An increase in BALF and peripheral blood neutrophils and in ENO was found 6hs after LPS (p<0.05). Table 1 show the prophylactic and therapeutic beneficial effects of SK in ALI mice. In conclusion, SK reduces inflammation and collagen deposition in a murine ALI model, pointing out SK as a potential therapeutic agent to be better investigated in ALI.
