The extensive neutrophil migration and the consequent tissue damage are present in several inflammatory diseases. Therefore, the investigation for drugs that interfere with the traffic of neutrophils in the inflammatory process has been increasing. Initial studies of our research group with neovestitol and vestitol, compounds isolated from propolis type 13 (red), and a bioactive fraction identified of geopropolis of Melipona scutellaris showed promising inhibition of neutrophil migration. However, more studies are necessary for the isolation and identification of the compound responsible by the activity of bioactive fraction, as well as demonstrate the efficiency of these isolated compounds on inhibition of migration neutrophils, followed by elucidation of their mechanisms of action. The objective of this study is to evaluate the activity and possible mechanisms of compounds isolated from Brazilian propolis on modulation of neutrophil migration in inflammatory process. The study will be conducted in two phases: the first will be made by the isolation of bioactive compounds (neovestitol and vestitol) of propolis, as well as the isolation and identification of bioactive compound of geopropolis fraction; in the second phase, will be applied biological assays with the isolated compounds of both propolis, where the activity will be evaluated on: migration of neutrophils induced by LPS or mBSA; leukocyte rolling and adhesion in venular endothelium; synthesis and/or liberation of inflammatory mediators (TNF-±, CXCL1/KC, CXCL2 e LTB4) in vivo; expression of molecules like P-selectin, ICAM-1 (present at endothelial cells); synthesis and/or liberation of inflammatory mediators by neutrophils production; the intracellular signaling pathways and the expression of Toll-like receptor (TLR) 2 and TLR4 and B2-integrin in neutrophils in vitro; neutrophils chemotaxis in vitro and the intracellular levels of calcium; the molecular mechanisms of the action and toxicological effects in genomic expression of human cells. It is expected that this study obtains bioactive compounds isolated from two varieties of Brazilian propolis capable of inhibiting neutrophil migration induced by different inflammatory stimuli and has its mechanism of action elucidated. Furthermore, these new information will contribute for the use of these compounds as a novel anti-inflammatory agents or prototypes of new drugs. (AU)
