1. The catechol-O-methyltransferase inhibitory potential of Z-vallesiachotamine by in silicoand in vitro approaches
AbstractZ-Vallesiachotamine is a monoterpene indole alkaloid that has a β-N-acrylate group in its structure. This class of compounds has already been described in different Psychotriaspecies. Our research group observed that E/Z-vallesiachotamine exhibits a multifunctional feature, being able to inhibit targets related to neurodegeneration, such as monoamin

2. Potentiometric quantification and speciation of oxygenated groups in humic substances using BEST7 software
In this study the BEST7 software was employed to quantify different classes of functional groups and to model the proton titration behavior of humic substances. To illustrate the process, the Suwannee River fulvic acid of the IHSS (International Humic Substances Society) was used. Five categories - two classes of phenolic groups (phenol and cathecol), two cl

3. Influência do contra-íon usado na eletrossíntese do polipirrol em sua resposta como biossensor eletroquímico após a imobilização da polifenol oxidase / Influence of counter-ion used in the electrosynthesis of polypyrrole in your response as electrochemical biosensors after polyphenol oxidase immobilization
Neste trabalho, foram fabricados biossensores amperométricos a partir do uso da polifenol oxidase (PFO), obtida do abacate como fonte enzimática, imobilizada em filmes de polipirrol (PPI) e que foram eletrossintetizados em meio de três diferentes eletrólitos de suporte (NaCl e NaClO4 e NaDDS). O método de imobilização enzimática foi o da adsorção,

4. Síntese e caracterização de complexos de rutênio com ligantes fenólicos / Synthesis and Characterization of Ruthenium complex with phenolic ligand
Estudos recentes mostram que a reação entre o complexo mer-[RuCl3(dppb)(H2O)] (dppb = 1,4- bis(difenilfosfino)butano) e a 1,2- fenilenodiamina produz os complexos amido- e imino-, com a coordenação ocorrendo nas posições ocupadas pelo cloro e pela água no complexo inicial. Baseando-se em procedimentos da literatura, com algumas modificações realizou

5. Efeito da quitosana e da radiação UV-C no controle de Guignardia citricarpa em laranja pós-colheita / Effect of chitosan and UV-C on the control of Guignardia citricarpa on postharvest orange
Brazil is the biggest producer and exporter of orange juice, and this is one of the most important economical activities for the country. The fruits can be affected by the citrus black spot, disease caused by the fungus Guignardia citricarpa, which depreciates then commercially, causes premature fall and increases the production cost. Alternative measures to

6. Synthesis, characterization and study of catalytical properties of mixed layered hydroxides containing Cu(II)/Mg(II)/Al(III) / Síntese, caracterização e estudo de propriedades catalíticas de hidróxidos mistos lamelares contendo Cu(II)/Mg(II)/AI(III)
In this work it was investigated the preparation and spectroscopic characterization of layered hydroxides of composition [Mg3-xCuxAl(OH)8](CO3)0.5.yH2O (x = 0.3; 0.6; 0.9; 1.2; 1.5; 1.8; 2.1; 2.4; 2.7 and 3.0), as well the reactivity of these materials towards phenol hydroxylation, using hydrogen peroxide as oxidizing agent. The solids had been prepared thro
