Antibacterial, antibiofilm and cytotoxic activities of Terminalia fagifolia Mar...
Araujo, Alyne Rodrigues de; Quelemes, Patrick Veras; Perfeito, Márcia Luana Gomes; Lima, Luiza Ianny de; Sá, Melka Coêlho; Nunes, Paulo Humberto MoreiraBackground: The methicillin resistance of bacteria from the genus Staphylococcus and its ability to form biofilms are important factors in pathogenesis of these microorganisms. Thus, the search for new antimicrobials agents, especially from plants, has been intensified. In this context, Terminalia species have been the subject of research for many pharmacological activities. In this study we evaluated the antib...
Antibacterial application of natural and carboxymethylated cashew gum-based sil...
Araruna, Felipe Bastos; de Oliveira, Taiane Maria; Quelemes, Patrick Veras; de Araújo Nobre, Alyne Rodrigues; Plácido, AlexandraThis study presents a green synthesis route to silver nanoparticles (AgNPs) stabilized with cashew gum (CG) or carboxymethylated cashew gum (CCG) using microwave-assisted synthesis and evaluates their antibacterial activity. The antimicrobial activity was measured by determining the minimum inhibitory concentration (MIC) with Staphylococcus aureus and Escherichia coli. In both cases of the presence of CG and CC...
Thaulin-1: The first antimicrobial peptide isolated from the skin of a Patagoni...
Marani, Mariela M.; Perez, Luis O.; Araujo, Alyne Rodrigues de; Plácido, Alexandra; Sousa, Carla F.; Quelemes, Patrick Veras; Oliveira, MayaraPatagonia's biodiversity has been explored from many points of view, however, skin secretions of native amphibians have not been evaluated for antimicrobial peptide research until now. In this sense, Pleurodema thaul is the first amphibian specie to be studied from this large region of South America. Analysis of cDNA-encoding peptide in skin samples allowed identification of four new antimicrobial peptides. The...

Characterization and Biological Activities of Ocellatin Peptides from the Skin ...
Marani, Mariela Mirta; Dourado, Flávio Santos; Quelemes, Patrick Veras; Araujo, Alyne Rodrigues de; Perfeito, Márcia Luana Gomes; Barbosa, Eder AlvesEight new peptides were isolated from the skin secretion of the frog Leptodactylus pustulatus and their amino acid sequences determined by de novo sequencing and by cDNA cloning. Structural similarities between them and other antimicrobial peptides from the skin secretion of Leptodactylus genus frogs were found. Ocellatins-PT1 to -PT5 (25 amino acid residues) are amidated at the C-terminus, while ocellatins-PT6...
