ABSTRACT
Wounds or chronic injuries are associated with high medical costs so, develop healing-oriented drugs is a challenge for modern medicine. The identification of new therapeutic alternatives focuses on the use of natural products. Therefore, the main goal of this study was to evaluate the healing potential and anti-inflammatory mechanism of action of extracts and the main compounds derived from Myrciaria plinioides D. Legrand leaves. The antimicrobial activity of leaf extracts was analyzed. Cell viability, cytotoxicity and genotoxicity of plant extracts and compounds were also assessed. Release of pro- and anti-inflammatory cytokines and TGF-ß by ELISA, and protein expression was determined by Western Blot. The cell migration and cell proliferation of ethanol and aqueous leaf extracts and p-coumaric acid, quercetin and caffeic acid compounds were also evaluated. The aqueous extract exhibited antibacterial activity and, after determining the safety concentrations in three assays, we showed that this extract induced p38-α MAPK phosphorylation and the same extract and the p-coumaric acid decreased COX-2 and caspase-3, -8 expression, as well as reduced the TNF-α release and stimulated the IL-10 in RAW 264.7 cells. In L929 cells, the extract and p-coumaric acid induced TGF-ß release, besides increasing the process of cell migration and proliferation. These results suggested that the healing properties of Myrciaria plinioides aqueous extract can be associated to the presence of phenolic compounds, especially p-coumaric acid, and/or glycosylated metabolites.
