In the search for alternative sources of new drugs, Brazilian fruit species could be an alternative option to be explored. Flavonoids present in their composition stand out for having anti-inflammatory action. Brazil is considered a major global producer of fruits, and has introduced fruits like açaí to the world market and encouraged research of other species as to their food and therapeutic potential, which add value and constitute a successful model of Brazilian agro-business. The aim of this project is to evaluate the anti-inflammatory activity, mechanism of action and phytochemical profile of fruit species native to Brazil. We selected 5 native fruits, namely: Eugenia leitonii (guava - piranga), Eugenia brasiliensis (grumixama), Eugenia involucrata (cherry Grand River), Eugenia Myrcianthes (ubajaí) and Garcinea brasiliensis (bacupari - mirim) for the exploration of anti-inflammatory activity. The plants will be harvested at pre-determined periods, and their parts (fruits, leaves, seed, bark) will be processed for obtaining hydroethanolic extracts (80:20, v/v), which will be lyophilized and stored at -20°C. The anti-inflammatory activity of extracts will be performed by means of a carrageenan-induced leukocyte migration model. We will select the extract with the best activity and submit it to a dose-response curve, followed by the evaluation of possible pathways of mechanisms of actios using models of Carrageenan-induced paw edema, quantification in vivo of inflammatory mediators (TNF-± ,IL-1², IL-10, CXCL1/KC and LTB4) and quantification in vitro of (TNF-±, IL-1², IL-10 e LTB4) with cells RAW 264.7, assessment of ICAM-1, VCAM-1, P- and E-selectin by Western blot and cell cytotoxicity (RAW 264.7). The chemical evaluation of the active extract will be performed by analysis of phenolic compounds, high performance liquid chromatography on reversed phase (HPLCRF-DAD) and mass spectrometry (HPLC/MS). This project is expected to contribute with information about the anti-inflammatory activity, mechanism of action and phytochemical profile of native species as well as to add value to domestic products.
