Resumo: A violaceína é um pigmento violeta produzido por algumas espécies bacterianas de origem ambiental, tais como Chromobacterium violaceum e Janthinobacterium lividum. Esta molécula apresenta várias propriedades biológicas incluindo antibacteriana, antifúngica, antiviral, antiprotozoária e antitumoral, apesar de sua função exata na fisiologia dos micro-organismos que a produz, ainda é desconhecido. No presente trabalho, a atividade antimicrobiana da violaceína produzida comercialmente, o extrato semi purificado e nanopartículas de vanadato de prata foram avaliados contra espécies de bacterianas gram-positivas e gram-negativas. A violaceína exibiu efeito antimicrobiano contra Staphylococcus aureus resistente à meticilina (MRSA) e Enterococcus resistente à vancomicina (VRE), que são micro-organismos frequentemente relacionados com infecções adquiridas em hospitais. Os valores de MIC (concentração inibitória mínima) e MBC (concentração bactericida mínima) da violaceína produzida comercialmente foram de 0,625 ?M e 1,25 ?M respectivamente e, análise de curvas de crescimento e tempo-morte revelaram um efeito antibacteriano durante 12 horas contra MRSA. A microscopia eletrônica de transmissão mostrou os efeitos da violaceína com alterações morfológicas e ultra estruturais, incluindo alterações na parede celular e formação de septos de divisão anormais. Nos resultados obtidos das análises de proteômica e transcriptoma a violaceína afetou a expressão de várias classes funcionais de proteínas e genes em MRSA, incluindo processos biológicos em biossíntese da parede celular e divisão celular que corroboram as alterações ultra estruturais visualizadas. Em conclusão, a violaceína produzida comercialmente demonstrou atividade antimicrobiana para S. aureus MRSA e pela primeira vez, os efeitos da violaceína sobre o metabolismo de S. aureus foram descritos, indicando possíveis alvos e vias metabólicas afetadas por esta droga. No seu conjunto, estes dados indicam a violaceína como uma droga potencial para o tratamento de infecções provocadas por MRSA
Abstract: Violacein is a violet pigment produced by some bacterial species of environmental source, such as Chromobacterium violaceum and Janthinobacterium lividum. This molecule has numerous biological properties including antibacterial, antifungal, antiviral, antiprotozoal and antitumor activity, although the exact role in the physiology of producing microorganisms is still unknown. In this study, the antimicrobial activity of violacein produced commercially, semi purified extract and silver vanadate nanoparticles were evaluated against several species of gram-positive and gram-negative bacteria. Violacein exhibited antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE), microorganisms that are often related to hospital-acquired infections. MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) values of violacein produced commercially were 1.25 ?M mM and 0.625 ?M respectively, and analysis of growth and time-kill curves showed an antibacterial effect against MRSA for 12 hours. The transmission electron microscopy showed the effects of violacein with morphological and ultra-structural changes, including changes in cell wall formation and abnormal division septum. The results obtained from the analysis of proteomic and transcriptomic revealed that violacein affects the expression of several functional classes of proteins and genes in MRSA, including biological processes in cell wall biosynthesis and cell division, supporting ultra-structural changes. In conclusion, violacein produced commercially demonstrated antimicrobial activity against S. aureus MRSA and the effects on the metabolism of S. aureus have been described, indicating possible targets and pathways affected by this drug. These data indicate violacein as a potential drug for the treatment of infections caused by MRSA

To address the current challenges raised by emerging diseases (COVID-19 pandemic) and antibiotic resistance, the search for new antimicrobials has become urgent. The present study aims to highlight the potential of plant species, selected according to ecological and chemotaxonomic criteria, as a natural source of compounds with a wide structural diversity and promising biological activities. Juncus species collected from 3 localities in France were investigated for their potential antimicrobial effect against coronaviruses and Gram-positive bacterial strains. For this purpose, the approach of bioguided fractionation was adopted through the use of conventional separation techniques (preparative HPLC and CPC). The antiviral study conducted against the coronavirus HCoV-229E highlighted the antiviral potential of luteolin, a flavone that was isolated from the EtOAc sub-extract of J. acutus stems (locality 2). The screening for antibacterial activity led to the selection of the CH2Cl2 sub-extract of J. inflexus rhizomes (locality 3) for the rest of this study as this enriched-phenanthrene derivative sub-extract demonstrated a remarkable activity in particular against S. aureus strains. Additional experiments to deepen the understanding of the antibacterial effect of some of the isolated phenanthrene derivatives were performed focusing on a methicillin-resistant S. aureus strain that was isolated from a diabetic foot infection. Regarding the promising results, the developement of a topical formulation involving juncusol as an active component was initiated. Bioavailibility studies were also performed on this phenanthrene derivative through in vitro absorption and intestinal permeability experiments across Caco2/HT29-MTX co-cultured cells
