Co-cultivo fúngico como estratégia para obtenção de metabólitos biologicamente ativos
(Universidade Federal de São Carlos, 2021-02-23)
In this work, the bactericidal, antiprotozoal, and inhibition of cathepsin V proteolytic activity of extracts from the axenic cultivation of six fungal species (Fusarium guttiforme, Pestalotiopsis diospyri, Phoma ...
Síntese, caracterização e avaliação da atividade fotoeletrocatalítica de filmes finos de Sb2S3
(Universidade Federal de São Carlos, 2020-08-27)
Photoelectrochemical cells (PECs) have been shown to be a promising system for H2 generation from photoelectrolysis of water. Among the semiconductors materials that have been studied for PECs, Sb2S3 stands out due to its ...
Avaliação in vitro da ação fotodinâmica antimicrobiana e antitumoral do complexo cis-[Ru(phen)2(pPDIp)]2+
(Universidade Federal de São Carlos, 2021-02-19)
Photodynamic therapy (PDT) activates a photosensitizer by visible or infrared light to generate cytotoxic oxygen species that lead to cell death. PDT is generally used in applications in superficial lesions and can be used ...
Imagens espectrais do processo de agregação da insulina por complexos metálicos luminescentes
(Universidade Federal de São Carlos, 2021-03-01)
Insulin is a protein hormone synthesized by β cells in the pancreas, which regulates the level of glucose in the blood. This protein was the first biopharmaceutical produced on an industrial scale for the treatment of ...
Avaliação da atividade citotóxica de complexos fosfínicos de Ru(II) com ligantes mercaptos e aciltioureias
(Universidade Federal de São Carlos, 2020-12-11)
In this thesis, two series of new Ru-phosphine complexes containing mercapto or acylthiourea ligands were synthesized, characterized and assessed their cytotoxic activities. The first series is composed of five complexes ...
Síntese de complexos de Mg(II), atividade antioxidante e citotóxica
(Universidade Federal de São Carlos, 2021-03-09)
The objective of this work was to develop metal complexes containing natural products that have antioxidant activity to be applied in the cosmetics sector. For that, 3 [Mg(phen)2PN]+ metal complexes were synthesized and ...
Evaluation of the biological activity of the disintegrin-like and cysteine-rich domains of Bothropasin, a metalloproteinase from Bothrops jararaca
(Universidade Federal de São Carlos, 2021-05-17)
Bothropasin is a 48kDa hemorrhagic class III Snake Venom Metalloproteinase (SVMP). As a multi-domain protein, it contains catalytic metalloproteinase (M), disintegrin-like (D), and cysteine rich domains (C). Integrins ...
Determinação de Si e Y em amostras agronômicas por espectrometria de emissão óptica com plasma induzido por micro-ondas
(Universidade Federal de São Carlos, 2021-05-20)
Different demands for analytical responses are presented in agricultural research. In this approach, this dissertation, divided into two chapters, seeks to offer analytical alternatives for plant breeding and fish nutrition ...
Eletrodo de pasta de carbono modificado com solvente eutético profundo hidrofóbico e sua aplicação voltamétrica
(Universidade Federal de São Carlos, 2021-03-01)
In this work, the use of hydrophobic deep eutectic solvent was proposed for the modification of carbon paste electrodes. Different HDES were prepared using fatty acids: octanoic, decanoic, and dodecanoic acids, and ...
Desenvolvimento de eletrodo modificado com o solvente eutético profundo cloreto de colina/glicerol para a determinação simultânea de paracetamol e diclofenaco
(Universidade Federal de São Carlos, 2021-04-22)
In this master’s dissertation has investigated the use of deep eutectic solvents (DES) for the development of electrochemical sensors. DES was immobilized on the surface of a glassy carbon electrode (GCE) within carbon ...
