Brazil is blessed with a great biodiversity, which constitutes one of the most important sources of biologically active compounds, even if it has been largely underexplored. As is the case of the Amazon and Atlantic rainforests, the Brazilian marine fauna remains practically unexplored in the search for new biologically active natural products. Considering(More)
Aspergillus tubingensis and Bionectria ochroleuca showed excellent extracellular ability to synthesize silver nanoparticles (Ag NP), spherical in shape and 35 ± 10 nm in size. Ag NP were characterized by transmission electron microscopy, X-ray diffraction analysis, and photon correlation spectroscopy for particle size and zeta potential. Proteins present in(More)
Silver nanoparticles (AgNPs) have been broadly used as antibacterial and antiviral agents. Further, interests for green AgNP synthesis have increased in recent years and several results for AgNP biological synthesis have been reported using bacteria, fungi and plant extracts. The understanding of the role and nature of fungal proteins, their interaction(More)
The recent increase in human diseases and cancers requires new drugs to combat them. Sources have been found in rare microorganisms, those from extreme habitats, and from endophytes. In this study, the biological activity of endophytic fungi associated with the Brazilian medicinal plant Combretum leprosum was assessed. Cytotoxic and antiproliferative(More)
Complexos de inclusões e misturas físicas contendo mistura isomérica E/Z (50:50) de 3-(4’bromo-[1,1’-bifenil]-4-il)-3-(4-bromofenil)-N,N-dimetil-2-propen-1-amina (BBAP) e β-ciclodextrina (β-CD) nas proporções molares de 1:1 e 1:2 foram analisados por microscopia eletrônica de varredura (SEM). O perfil de dissolução do BBAP e dos complexos de inclusões foram(More)
