Estudo espectroscópico por FTIR da conversão de etanol em catalisadores de Au suportados
(Universidade Federal de São Carlos, 2020-07-25)
In this work, an FTIR spectroscopic study of gold catalysts supported on monoclinic zirconia (with Au content of 2,5% w/w), was carried out in order to elucidate the surface nature of this catalyst in the dehydrogenation ...
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 ...
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 ...
