1. Suzuki-Miyaura Coupling between 3-Iodolawsone and Arylboronic Acids. Synthesis of Lapachol Analogues with Antineoplastic and Antileishmanial Activities
A series of 2-hydroxy-3-arylnaphthalene-1,4-diones (3-aryllawsones) were synthesized by Suzuki-Miyaura cross coupling reaction of 3-iodolawsone with arylboronic acids/esters. The hydroxylated resulting products were transformed into their corresponding N,N-diethyl carbamates. The antineoplastic and antileishmanial activities of the compounds were evaluated a

2. Cholinesterases Inhibition by Novel cis- and trans-3-Arylaminocyclohexyl N,N-Dimethylcarbamates: Biological Evaluation and Molecular Modeling
The present study describes the synthesis, assessment of the anticholinesterase activity and the inhibition type of novel cis- and trans-3-arylaminocyclohexyl N,N-dimethylcarbamates. In vitro inhibition assay by Ellman's method with human blood samples showed that carbamates were selective for butyrylcholinesterase (BuChE) with compound concentration that in

3. JVG9, a benzimidazole derivative, alters the surface and cytoskeleton of Trypanosoma cruzi bloodstream trypomastigotes
Trypanosoma cruzi has a particular cytoskeleton that consists of a subpellicular network of microtubules and actin microfilaments. Therefore, it is an excellent target for the development of new anti-parasitic drugs. Benzimidazole 2-carbamates, a class of well-known broad-spectrum anthelmintics, have been shown to inhibit the in vitro growth of many protozoa

5. Modelagem MIA-QSAR de inibidores de acetilcolinesterase= : MIA-QSAR modeling of inhibitors actylcholinesterase / MIA-QSAR modeling of inhibitors actylcholinesterase
O presente trabalho trata de um estudo sobre compostos que se comportam como inibidores da acetilcolinesterase, uma importante enzima do processo de cognição. A acetilcolinesterase atua na hidrólise da acetilcolina, responsável pela comunicação entre os neurônios. Uma das modalidades para o design racional de fármacos é a estimativa de propriedades

6. Determination of carbamates in beverages by liquid-liquid extraction with low temperature partitioning and liquid chromatography
Carbamatos são os pesticidas mais frequentemente encontrados em alimentos e bebidas de coloração escura em casos de intoxicação acidental ou intencional. Neste trabalho, extração líquido-líquido com partição em baixa temperatura (LLE-LTP) foi otimizada e validada para determinação dos carbamatos aldicarb, carbofuran e carbaril em bebidas de suco

7. Synthesis of compounds with potential anticholinesterase activity / Sínteses de compostos com potencial atividade anticolinesterásica
Este trabalho descreve um estudo teórico-experimental envolvendo derivados da Piridostigmina e do Edrofônio, que possuem ação como inibidores da enzima acetilcolinesterase. Os anticolinesterásicos são utilizados como medicamento para o tratamento do Mal de Alzheimer. Primeiramente foram sintetizados os derivados da Piridostigmina (brometo de N,N-dimeti

9. Otimização e validação de metodologia para determinação de aldicarbe e carbofurano em amostras de café bebida / Optimization and validation of methodology for determination of aldicarb and carbofuran in coffee samples
Domestic use of aldicarb and carbofuran has resulted in accidental or even intentional poisonings, making it a severe public health problem. A mixture of "chumbinho" (aldicarb) in coffee is frequently a poisoning agent due to strong odor and color of coffee which hide the presende of "chumbinho". Thus, the objective of this study was to adapt, optimize and v

10. Resistance of Diamonback moth, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) populations from Pernambuco state to insecticides / Resistência de populações pernambucanas de traças-das-crucíferas, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) a inseticidas
Plutella xylostella (L.) (Lepidoptera: Plutellidae), popularly known as diamondback moth, is a major pest of brassicaceae crops (e.g., kale, cauliflower, broccoli, and cabbage) throughout the world. Several insecticides have been intensively used during several cultivation cycles and, even in some areas, up to 15 to 20 applications per season have been obser

11. Hematological and enzymatic evaluation and measurement of metal levels in occupational exposure to agricultural chemicals and fertilizers. / Avaliação hematológica, atividade enzimática e níveis de metais na exposição ocupacional aos defensivos agrícolas e fertilizantes
Advancements in the agrochemical industry associated with new seeding techniques make it possible for the country to reach annual crop records in production. However, the chemicals and fertilizers used for increasing productions are by no means harmless to human health. Repeated and inadequate exposures to such chemicals may result in their absorption and ca
