Avaliacao da producao de cupuacu (Theobroma grandiflorum) em diferentes sistemas agroflorestais (Sistema 1- seringueira x pupunha x mamao x cupuacu; Sistema 2- castanha-do-brasil x pupunha x urucum x cupuacu; Sistema 3- laranja x seringueira x coco x parica x cupuacu; e Sistema 4- monocultivo de cupuacu) em um experimento implantado na area experimental do CPAA, onde as plantas em parcelas cobertas por pueraria foram submetidas a dois niveis de adubacao (100% da adubacao recomendada e 30% da recomendada combinada com (C) e sem (S) inoculacao das plantas com FMVA). De acordo com os resultados parciais, os tratamentos nao exerceram influencia na producao de frutos. As plantas do Sistema 1 apresentaram maior producao que as dos demais sistemas. |

Proline-rich oligopeptides (PROs) are a large family which comprises the bradykinin-potentiating peptides (BPPs). They inhibit the activity of the angiotensin I-converting enzyme (ACE) and have a typical pyroglutamyl (Pyr)/proline-rich structure at the N- and C-terminus, respectively. Furthermore, PROs decrease blood pressure in animals. In the present study, the isolation and biological characterization of a novel vasoactive BPP isolated from the skin secretion of the frog Brachycephalus ephippium is described. This new PRO, termed BPP-Brachy, has the primary structure WPPPKVSP and the amidated form termed BPPBrachyNH2 inhibits efficiently ACE in rat serum. In silico molecular modeling and docking studies suggest that BPP-BrachyNH2 is capable of forming a hydrogen bond network as well as multiple van der Waals interactions with the rat ACE, which blocks the access of the substrate to the C-domain active site. Moreover, in rat thoracic aorta BPP-BrachyNH2 induces potent endothelium-dependent vasodilatation with similar magnitude as captopril. In DAF-FM DA-loaded aortic cross sections examined by confocal microscopy, BPP-BrachyNH2 was found to increase the release of nitric oxide (NO). Moreover, BPP-BrachyNH2 was devoid of toxicity in endothelial and smooth muscle cell cultures. In conclusion, the peptide BPP-BrachyNH2 has a novel sequence being the first BPP isolated from the skin secretion of the Brachycephalidae family. This opens for exploring amphibians as a source of new biomolecules. The BPP-BrachyNH2 is devoid of cytotoxicity and elicits endothelium-dependent vasodilatation mediated by NO. These findings open for the possibility of potential application of these peptides in the treatment of endothelial dysfunction and cardiovascular diseases.
