Abstract
Staphylococci are pathogenic biofilm-forming bacteria and a source of multidrug resistance and/or tolerance causing a broad spectrum of infections. These bacteria are enclosed in a matrix that allows them to colonize medical devices, such as catheters and tissues, and that protects against antibiotics and immune systems. Advances in antibiofilm strategies for targeting this matrix are therefore extremely relevant. Here, we describe the development of the Capsicum pepper bioinspired peptide "capsicumicine." By using microbiological, microscopic, and nuclear magnetic resonance (NMR) approaches, we demonstrate that capsicumicine strongly prevents methicillin-resistant Staphylococcus epidermidis biofilm via an extracellular "matrix anti-assembly" mechanism of action. The results were confirmed in vivo in a translational preclinical model that mimics medical device-related infection. Since capsicumicine is not cytotoxic, it is a promising candidate for complementary treatment of infectious diseases. IMPORTANCE Pathogenic biofilms are a global health care concern, as they can cause extensive antibiotic resistance, morbidity, mortality, and thereby substantial economic loss. So far, no effective treatments targeting the bacteria in biofilms have been developed. Plants are constantly attacked by a wide range of pathogens and have protective factors, such as peptides, to defend themselves. These peptides are common components in Capsicum baccatum (red pepper). Here, we provide insights into an antibiofilm strategy based on the development of capsicumicine, a natural peptide that strongly controls biofilm formation by Staphylococcus epidermidis, the most prevalent pathogen in device-related infections.

Abstract
Background The increase in bacterial resistance phenotype cases is a global health problem. New strategies must be explored by the scientific community in order to create new treatment alternatives. Animal venoms are a good source for antimicrobial peptides (AMPs), which are excellent candidates for new antimicrobial drug development. Cathelicidin-related antimicrobial peptides (CRAMPs) from snake venoms have been studied as a model for the design of new antimicrobial pharmaceuticals against bacterial infections. Results In this study we present an 11 amino acid-long peptide, named pseudonajide, which is derived from a Pseudonaja textilis venom peptide and has antimicrobial and antibiofilm activity against Staphylococcus epidermidis. Pseudonajide was selected based on the sequence alignments of various snake venom peptides that displayed activity against bacteria. Antibiofilm activity assays with pseudonajide concentrations ranging from 3.12 to 100 μM showed that the lowest concentration to inhibit biofilm formation was 25 μM. Microscopy analysis demonstrated that pseudonajide interacts with the bacterial cell envelope, disrupting the cell walls and membranes, leading to morphological defects in prokaryotes. Conclusions Our results suggest that pseudonajide’s positives charges interact with negatively charged cell wall components of S. epidermidis, leading to cell damage and inhibiting biofilm formation.

Abstract
Medical devices (indwelling) have greatly improved healthcare. Nevertheless, infections related to the use of these apparatuses continue to be a major clinical concern. Biofilms form on surfaces after bacterial adhesion, and they function as bacterial reservoirs and as resistance and tolerance factors against antibiotics and the host immune response. Technological strategies to control biofilms and bacterial adhesion, such as the use of surface coatings, are being explored more frequently, and natural peptides may promote their development. In this study, we purified and identified antibiofilm peptides from Capsicum baccatum (red pepper) using chromatography-tandem mass spectrometry, MALDI-MS, MS/MS and bioinformatics. These peptides strongly controlled biofilm formation by Staphylococcus epidermidis, the most prevalent pathogen in device-related infections, without any antibiotic activity. Furthermore, natural peptide-coated surfaces dislayed effective antiadhesive proprieties and showed no cytotoxic effects against different representative human cell lines. Finally, we determined the lead peptide predicted by Mascot and identified CSP37, which may be useful as a prime structure for the design of new antibiofilm agents. Together, these results shed light on natural Capsicum peptides as a possible antiadhesive coat to prevent medical device colonization.

Abstract
Pathogenic biofilms are a global health care concern, as they can cause extensive antibiotic resistance, morbidity, mortality, and thereby substantial economic loss. Scientific efforts have been made over the past few decades, but so far there is no effective treatment targeting the bacteria in biofilms. Antimicrobial peptidomimetics have been proposed as promising potential anti-biofilm agents. Indeed, these structurally enhanced molecules can mimic the action of peptides but are not susceptible to proteolysis or immunogenicity, the characteristic limitations of natural peptides. Here, we provide insights into antibiofilm peptidomimetic strategies and molecular targets, and discuss the design of two major peptidomimetics classes: AApeptides (N-acylated-N-aminoethyl-substituted peptides) and peptoids (N-substituted glycine units). In particular, we present details of their structural diversity and discuss the possible improvements that can be implemented in order to develop antibiofilm drug alternatives.

Abstract
Pterocaulon polystachyum DC is a native species to southern Brazil, Paraguay, Uruguay and northeastern Argentina. It is utilized to treat animal problems popularly diagnosed as "mycoses". The antifungal and amebicidal activity of its hexane extract has been previously reported, although there are no studies confirming the safety of this plant for therapeutic purposes to date. Hence, this study investigates the toxic effects of a hexane extract of Pterocaulon polystachyum administered as acute and subacute oral treatments. After acute treatment the extract caused alterations in biochemical parameters, morphological alterations in tissues and was genotoxic, according to the comet assay; neither mortality nor visible signs of lethality were seen in mice. Similarly subacute treatment caused important differences in biochemical parameters and tissues, between control and treated groups. The results also revealed genotoxicity in kidney tissue, though no mutagenicity was detected by the micronucleus test. No animal died during the treatment period.

Abstract
Duloxetine is a potent inhibitor of serotonin and noradrenaline reuptake, with weak effects on dopamine reuptake, used in the treatment of major depression. It has been recognized that some antidepressants can affect memory in humans, but there is not study that report the duloxetine effect on memory using the inhibitory avoidance. The aim of this work was to investigate the effect of duloxetine on short- and long-term memory (STM and LTM) in the inhibitory avoidance task in mice. Duloxetine (10 and 20 mg/kg; i.p.) administered before or after the inhibitory avoidance training was not able to produce effects on STM e LTM (p>0.05). The group that received MK-801 (0.0625 mg/kg), an NMDA receptor antagonist, showed an impairment in STM and LTM (p<0.01). These effects were not reversed by duloxetine administration (p=0.114 and p=0.06, respectively). Duloxetine effect on memory 5 days after i.p. administration was also investigated. After this treatment both duloxetine doses used were unable to affect STM or LTM in the inhibitory avoidance task (p=0.371 and p=0.807, respectively). DNA damages were evaluated in brain tissues and blood by the comet assay, after subacute treatment (10 or 20 mg/kg by 5 days). Duloxetine did not induce genotoxic effects. However, when the cells were treated ex vivo hydrogen peroxide, a pro-oxidant effect on brain tissue from treated animals was observed with significantly higher DNA damage in comparison to untreated animals, suggesting increased susceptibility to injuries by reactive oxygen species in brain after treatment with duloxetine. Duloxetine did not produce any effect on memory after acute and subacute administration, suggesting that this antidepressant does not affect either memory acquisition or consolidation.
