2. Synthesis of Triazoles by Electro-Assisted Click Reaction Using a Copper Foil Electrode
This paper presents an innovative pathway for the synthesis of triazoles using the well-known “click chemistry” assisted by the electrochemical oxidation of metallic Cu0. The click reaction is used to couple a wide range of biological interest compounds. In this case, faster and less polluting methods for a biological environment was achived by in situ C

3. Study of the CuII Affinity by Three Chelating Agents of Biological Interest: TPEN, TRIEN and Et2DTC
Copper is an important micronutrient, and it is present in some protein structures, as well as participate in several important biological processes. Due to its importance, some ligands are used and studied like carriers of copper in the biological systems. This work has investigated the affinity of CuII by three ligands of biological interest: N, N, N, N’

4. Structural and biological properties of protein hydrolysates from seafood by-products: a review focused on fishery effluents
Abstract Enormous amounts of by-products and waste are generated during the processing of seafood, sometimes representing about 65% of the raw material employed. Seafood by-products (SB) include solid waste such as skin, head, viscera, trimmings, and bones; however, liquid wastes (effluents) derived from operations such as washing, thawing, cooking and the p

5. Chitosan and Agaricus brasiliensis Polysaccharides Films: A Preliminary Study
The known biotechnological properties of chitosan and the recent biological activities attributed to polysaccharides from Agaricus brasiliensis have been of interest to obtain films constituted by these two polymers. The glucans obtained from the mushroom inhibited about 96.5% of the ferrous ion, besides not promoting a significant increase of lactate dehydr

6. EVALUATION OF THE METABOLIC PRODUCTION OF THE ENDOPHYTIC FUNGUS Phomopsis sp.
Endophytic microorganisms have been shown to be an important source of bioactive compounds, and much has been studied about their metabolites. For example, compounds with different biological activities have been isolated from Phomopsis sp. The metabolic study of this genus may lead to a better understanding of the routes of production of metabolites of inte

7. Floral Diversity in Different Types of Honey
Abstract Many different types of honey are available in the Brazilian market. They vary in color, flavor, smell, thereby increasing interest in honey characterization relating to botanical origin. A total of 155 honey samples belonging to Brazilian flora were examined on the pollen analysis; sampling is made in a span of one year. The preparation followed me

8. Naming structures and qualifying properties of anuran bioacoustical signals: a call for a homology-based nomenclature and equality for quantitative data
Abstract: There is a significant interest for using call features in taxonomic and systematic studies. However, the indiscriminate use of alternative terms for the acoustic structures has precluded reliable comparisons among species without directly checking recordings of all compared species. Recent attempts of nomenclature standardization have focused on t

10. The Research on Porphyrins and Analogues in Brazil: A Small Review Covering Catalytic and other Applications since the Beginning at Universidade de São Paulo in Ribeirão Preto until the Joint Venture between Brazilian Researchers and Colleagues from Universidade de Aveiro, Portugal
The synthetic versatility and the potential applications of porphyrins and analogues in different fields have aroused special interest in their study, especially to mimic biological systems, such as cytochrome P-450. The ability of the porphyrin tetrapyrrolic core to accommodate metal ions of varying charges can modulate the type of application of these comp

11. SBSE(EG-Silicone)-UFLC-MS/MS and HPLC-Flu Analysis of Norharman in Passiflora edulis Rinds
Previous studies on Passiflora edulis (sour passion fruit) rinds reported some biological activities and there is a growing interest on rinds flour as a possible functional food, but its alkaloid composition was not detailed investigated. This work reports on for the first time in the literature the identification of norharman in P. edulis rinds, by using st

12. Aspergillus niger: A Hundred Years of Contribution to the Natural Products Chemistry
Aspergillus niger is a phytopathogenic fungus responsible for the plant disease called “black mold”, and it is considered the most versatile microorganism for producing acids, proteins, and enzymes of industrial value, besides a variety of compounds of pharmacological interest. This review presents a century of contribution of A. niger in the natural pro
