Abstract: En | Text: En | PDF: En

Cathepsin K is a papain-like cysteine protease and is responsible for collagen degradation in bone tissue and thus represents an important target for the development of new therapies for treating diseases such as osteoporosis. Quinolines are an important class of heterocyclic molecular leads with a great pharmacological potential and represent a relevant scaffold to explore the chemical space of cathepsin K (CatK) inhibitors. This study presents the synthesis of nine 2,4-diphenylquinolines, including five phthalonitrile quinolines dyads, and the evaluation of their CatK inhibitory activity. Among the evaluated compounds, 4b was the most potent inhibitor with an IC50 (half-maximal inhibitory concentration) value of 1.55 µM (against Z-Phe-Arg-MCA substrate) acting in an uncompetitive inhibition mode. Molecular docking studies provided important information on the interaction of the inhibitor with the enzyme showing that these quinoline derivatives can play an important role as CatK inhibitors.

Resumo O objetivo deste estudo foi pesquisar a ocorrência de Toxoplasma gondii em ovinos abatidos no Estado de Alagoas, Brasil por meio de diferentes técnicas de diagnóstico. Foram utilizadas amostras de soros e tecidos de 100 ovinos abatidos. Para a pesquisa de anticorpos foi utilizada a Reação de Imunofluorescência Indireta (RIFI), e os tecidos dos animais soropositivos (ponto de corte ≥1:64) foram submetidos às técnicas de Reação de Cadeia da Polimerase (PCR) e Imunohistoquímica (IHQ). Para o estudo da concordância entre as técnicas diretas foi empregado o teste Kappa. Na RIFI, 14% (14/100) das amostras foram soro-positivas. Na PCR, 21,43% (3/14) dos animais foram positivos e, na IHC, 7,14% (1/14) apresentaram marcação positiva para T. gondii no tecido cerebral. Na histopatologia, o achado predominante foi o infiltrado celular mononuclear no coração e manguito perivascular no cérebro e cerebelo. A concordância entre as técnicas diretas de diagnóstico foi moderada (K= 0,44). Desse modo, é importante utilizar diferentes técnicas diretas no diagnóstico da toxoplasmose em ovinos naturalmente infectados.

Abstract The aim of this study was to investigate occurrence of Toxoplasma gondii in sheep slaughtered in the state of Alagoas, Brazil, by means of different diagnosis techniques. Serum samples and tissues from 100 slaughtered sheep were used. To detect antibodies, the indirect immunofluorescence antibody test (IFAT) was used, and tissues from seropositive animals (cut-off ≥1:64) were submitted to Polymerase Chain Reaction (PCR) and immunohistochemistry (IHC). To assess the concordance between the direct techniques, the kappa test was used. In the IFAT, it was observed that 14% (14/100) of the ovine samples were serum-positive. In the PCR, 21.43% (3/14) of the animals were positive and in IHC, it was observed that 7.14% (1/14) were positively stained for T. gondii in cerebral tissue. Histopathologically, the predominant finding was the presence of mononuclear cell infiltrate in the heart and a perivascular cuff in the cerebrum and cerebellum. The concordance between the direct diagnosis techniques was moderate (k=0.44). Thus, it is important to use different direct techniques in diagnosing toxoplasmosis in naturally infected sheep.

Resumo Apresenta-se uma síntese atualizada de informações sobre algas no Brasil objetivando refinar os dados reunidos até o presente, bem como avaliar os avanços sobre o conhecimento da diversidade de algas no país desde a publicação do Catálogo de Plantas e Fungos do Brasil. Os resultados de 2015 mostraram um acréscimo de 1.250 espécies (35.7%) a um total de 4.747 em relação a 2010. As classes mais diversas em número de espécies foram Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae e Euglenophyceae. Bacillariophyceae e Cyanophyceae tiveram o maior acréscimo de espécies no intervalo de cinco anos. A região Sudeste e Sul foram as mais diversas, porém, as regiões Nordeste com os estados do Piauí e Sergipe e Centro-Oeste com os estados de Mato Grosso, Goiás e Distrito Federal destacaram-se no cenário da biodiversidade nacional. Apesar da escassez de taxonomistas e da infraestrutura limitada, os resultados obtidos evidenciaram um avanço significativo no conhecimento da diversidade de algas no país nesse período de cinco anos, iniciando uma mudança quanto as diferenças geográficas regionais.

Abstract An updated synthesis of cyanobacteria and algae information is presented for Brazil aiming to refine the data gathered to date and evaluate the progress of the biodiversity knowledge about these organisms in the country since the publication of the Catálogo de Plantas e Fungos do Brasil. The results of 2015 showed an increase of 1,250 species (35.7%) when compared to 2010, reaching a total of 4,747 species. The most diverse classes in species number were the Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae and Euglenophyceae. Bacillariophyceae and Cyanophyceae had the highest increase in species number in the five-year interval. The Southeast and South regions were the most diverse, however, the Northeast, with the states of Piauí and Sergipe, and the Central-west region, with Mato Grosso, Goiás and Distrito Federal, also stood out in the national algal biodiversity scenario. Despite the shortage of taxonomists and limited infrastructure, the results showed a significant improvement in the knowledge regarding the diversity of cyanobacteria and algae in the country during the study period, starting to even out regional geographical differences caused by subsampling.

Visando avaliar os efeitos do estresse hídrico sobre as trocas gasosas de CO2 e H2O, mudas de paratudo com cinco meses de idade cultivadas em sacos de plantio foram submetidas a estresse hídrico simulado pela supressão da irrigação durante 21 dias. Após 14 dias de supressão de irrigação, os valores de transpiração, condutância estomática e fotossíntese líquida das folhas foram nulos, enquanto o potencial hídrico das folhas atingiu -2,4 MPa. A partir deste ponto foi reiniciada a irrigação diária, sendo que após 96 horas as taxas voltaram a oscilar na faixa dos valores iniciais (transpiração - 3,2 a 3,5 mmol m-2 s-1; condutância estomática - 0,32 a 0,35 mol m-2 s-1; e, fotossíntese - 8,0 a 9,8 µmol m-2 s-1), além do potencial hídrico voltar a apresentar valores similares ao início do experimento (-0,6 MPa), demonstrando que a espécie possui mecanismos para tolerar déficit hídrico durante um período que pode ser considerado ecologicamente relevante.

To evaluate the effects of hydric stress on CO2 and H2O exchange, five-month-old Tabebuia aurea seedlings cultivated in planting bags were subjected to hydric stress by suppressing irrigation for 21 days. After 14 days without irrigation, the rates of transpiration, stomatal conductance and net photosynthesis in leaves were zero, while the hydric potential of leaves reached -2.4 MPa. After this point, daily irrigation was resumed, and the values of the measured variables recovered to initial levels after 96 hours (transpiration rate from 3.2 to 3.5 mmol m-2 s-1; stomatal conductance rate from 0.32 to 0.35 mol m-2 s-1 and photosynthesis rate from 8.0 to 9.8 µmol m-2 s-1). Likewise, hydric potential values were similar to those at the beginning of the experiment (-0.6 MPa). These results demonstrate that T. aurea has mechanisms to tolerate a period of hydric deficit, which may be considered ecologically relevant.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Neste trabalho é apresentada uma análise teórica detalhada da estabilidade relativa dos adutos endo/exo formados entre o ciclopentadieno (1) e a 1,4-benzoquinona (2). As coordenadas intrínsecas de reação (IRC) indicaram a presença de apenas um estado de transição para a reação, mostrando que se trata de um mecanismo concertado para ambos os adutos, endo 3 e exo 4. As energias dos adutos foram calculadas com um alto nível de teoria (CBS-Q) confirmando que o aduto endo é mais estável que o exo, o que está em desacordo com o que é observado para reações que usualmente seguem a regra de Alder. Uma análise estrutural eletrônica foi realizada através da metodologia NBO, a qual indicou que interações atrativas predominam sobre as interações estéricas repulsivas no aduto endo. Em resumo, para a reação de cicloadição estudada o aduto endo é o produto termodinâmico e cinético, o que pode ser confirmado também pelos dados experimentais mencionados neste trabalho.

In this work it is presented a detailed theoretical analysis of the relative stability of endo/exo Diels-Alder adducts formed by the reaction between cyclopentadiene (1) and 1,4-benzoquinone (2). The intrinsic reaction coordinate (IRC) showed the existence of only one transition state for the reaction studied, for both endo 3 and exo 4 adducts. The energies of both adducts were obtained at high level of theory (CBS-Q) confirming that the endo adduct is more stable than exo, which is in the opposite way to the observed in reactions that usually follow Alder's rule. An electronic structure analysis was performed through NBO methodology, indicating that the attractive delocalization interaction predominates over the steric repulsive interaction in the endo adducts. In summary, for the studied cycloaddition reaction the endo adduct is the thermodynamic and kinetic product, which can be also confirmed by experimental data mentioned in this work.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Este trabalho teve como objetivo estudar o estrato arbóreo de uma formação savanoide típica do Pantanal de Miranda, o paratudal, no Município de Corumbá, MS. O estrato herbáceo da formação é dominado por Paspalum hydrophilum e o estrato arbóreo, Tabebuia áurea. O paratudo, razão do nome, apresenta densidade média de 363 indivíduos por hectare, altura média de 6,7 m e diâmetro médio do caule de 16,7 cm. O paratudal de algumas regiões do Pantanal de Miranda poderia ser o resultado do solo (fator edáfico), da inundação (fator hidrométrico) e, ou, da ação antrópica, além de, em alguns casos, da associação com artrópodes que formam montículos - murundus -, nos quais T. aurea pode se estabelecer. Essa espécie deve apresentar mecanismos fisiológicos que lhe permitem sobreviver com níveis altos de cálcio e magnésio, enfrentar meses de seca e inundação (estresse hídrico) e mudanças no pH do solo.

This work aimed to study the "paratudal", an arboreal savanna formation of the Pantanal de Miranda, Corumbá - MS. There is a predominance of Paspalum hydrophilum grass and Tabebuia aurea tree species. The "paratudal" presents a mean density of 363 individuals/ha, height average of 6.7 m and stem diameter of 16.7 cm. This vegetation formation in some regions of the Pantanal de Miranda could be a result of the soil characteristics, flooding, human factor, and association with arthropods that form wooded hills, whereupon the species can be established. This species must present physiological mechanisms that allow it to survive with high levels of calcium and magnesium; alternated months of drought and flood and changes in the soil pH.

A espécie Tabebuia aurea é encontrada em áreas de Cerrado, Caatinga, Floresta Amazônica e Pantanal, sendo utilizada para fins ornamentais, medicinais, construção civil, carpintaria e produção de carvão, entre outros. Por apresentar ampla utilização e distribuição, os objetivos deste estudo foram caracterizar morfologicamente e analisar a viabilidade e o vigor das sementes dessa espécie quando colhidas e armazenadas por diferentes períodos. As sementes foram germinadas recém-colhidas, 30, 60 e 90 dias após o armazenamento em laboratório e em campo, sendo também submetidas ao teste de tetrazólio. As sementes mediram, em média, 57,8 x 20,6 x 3,1 mm (com alas) e 17,3 x 13,3 x 1,7 mm (sem alas), sendo assimétricas. Seu peso médio foi de 13,18 g (com alas) e 11,55 g (sem alas). As sementes apresentaram maior viabilidade quando recém-colhidas, maior porcentagem de germinação em laboratório após 30 dias de armazenamento e maior porcentagem de germinação acumulada a campo quando semeadas na superfície. A viabilidade das sementes, medida através do teste de tetrazólio, apresentou resultados similares aos obtidos por meio do teste de germinação em laboratório, indicando ser esse teste adequado para medir a viabilidade desta espécie.

Tabebuia aurea is found in areas of Cerrado, Caatinga, Amazon Forest and Pantanal., It is used medicinally, for landscaping, and as timber for construction. For presenting wide use and distribution, the objective of this study was to characterize morfologically and analyze the viability and vigor of the harvested seeds of this species originated from the Cerrado. The seeds were germinated immediately after harvest and at 30, 60 and 90 days after the storage in laboratory and field, being also tested with tetrazolium. Seeds measured, in average, 57.8 x 20.6 x 3.1 mm (with wings) and 17.3 x 13.3 x 1.7 mm (without wings), which were antisymmetrical . The average seed weight was 13.18 g (with wings) and 11.55 g (without wings). T. Aurea presented greater viability immediately after harvest, greater percentage of germination in laboratory 30 days after storage, and greater percentage of accumulated germination on field surface. Seed viability, checked by the tetrazolium test, gave results similar to the ones obtained from the germination test in laboratory, indicating that it is satisfactory to test the viability of this species.
