Повний текст джерелаIn this work, we have developed a chemoenzymatic method to enantiomerically synthesize enriched organoselenium amines (1-(2, 3 or 4 -(ethylselanyl)phenyl)ethanamine) and amides (N-(1-(2, 3 or 4-(ethylselanyl)phenyl)ethyl)acetamide). Initially, the organoselenium amines, in the racemic form, were synthesized from ortho-, meta- and para- aminoacetophenones. The incorporation of the selenium atom into the aromatic ketones was achieved by the use of reaction of potassium selenocyanate and diazonium salts, prepared from aminoacetophenones, to afford selenocyanate acetophenones (28-65 %). These compounds were alkylated with alkyl halide to yield the organoselenium acetophenones (1-(2, 3 or 4-(ethylselanyl)phenyl)ethanone) (63-78 %) which were converted into their corresponding racemic organoselenium amines by reductive amination (39-73 %). After developing the protocol for the synthesis of racemic organoselenium amines, we studied the kinetic resolution of these compounds by their acetylation mediated by lipases. An initial study was carried out with the organoselenium amine para substituted, as a model substrate, in order to screen for appropriate lipase, solvent, temperature, lipase/substrate ratio and acylant. This study showed that the ideal condition to conduct the kinetic resolution was CAL-B as biocatalyst, hexane as solvent and ethyl acetate or ethyl methoxyacetate as acylant at 30°C. By using this protocol, the organoselenium amides were prepared in excellent enantiomeric excess (99 %).

The efficiency of the extrusion process is directly related to the total energy transferred to the dough feed. Single screw extruders usually implement around 20kWh / ton of specific mechanical energy (SME), but less is known about the implementation of the specific thermal energy (STE) and the implications of the relationship between STE/SME processing of dog food and cats. This study evaluated the effects of the implementation of three relations between STE/SME on the macrostructure of estrusados, gelatinization, loss of nutrients, nutrient digestibility and palatability of food for dogs and cats. For each species, the experiment included a formulation processed in order to obtain three relations STE/SME totaling three diets for species. Nutrient digestibility was studied in 18 dogs or 18 cats, the total collection of feces. The palatability of the diets was compared for the two vessels method, at least 30 animals by comparison. The data were submitted to ANOVA and Tukey's test (P <0.05). Feed production was possible with different SME (8, 20 and 30 kWh / t) and relations STE/SME, but with total specific energy next. These had the same bulk density, gelatinization of starch and resistant starch. Provided to animals showed digestibility and similar energy production and resulted in similar characteristics of feces and does not alter the concentration of the fermentation product in the feces. There was, however, greater complexation fat as applied SME over the products (P <0.05). Dogs and cats had lower consumption of feed with 30 kWh / t, compared others (P <0.05). Dogs further preferred feed 20 over the 8 kWh / t (P <0.05), while for the latter cats had similar consumption.

Повний текст джерелаSelenoproteins are a diverse family of proteins containing the trace element Selenium (Se)in the form of the non-canonical amino acid selenocysteine (Sec). Selenocysteine, the 21st amino acid, is similar to cysteine (Cys)but with Se replacing Sulphur. In many cases the homologous gene of a known selenoprotein is present with cysteine in the place of Sec in a different genome. Selenoproteins are believed to be the effectors of the biological functions of Selenium and have been implicated in male infertility, cancer and heart diseases, viral expression and ageing. Selenocysteine is coded by the opal STOP codon (TGA). A number of factors combine to achieve the co-translational recoding of TGA to Sec. The 3' Untranslated regions (UTRs) of eukaryotic selenoprotein transcripts contain a stem-loop structure called a Sec Insertion Sequence (SECIS) element. This is recognised by the Secis Binding Protein 2 (SBP2), which binds to both the SECIS element and the ribosome. SBP2, in turn, recruits the Sec-specific Elongation Factor EFsec, and the selenocysteine transfer RNA, tRNASec. The dual meaning of the TGA codon means that selenoprotein genes are often mispredicted by the standard annotation pipelines. The correct prediction of these genes, therefore, requires the development of specific methods. In the past few years we have contributed significally to the description of the eukaryotic selenoproteome2 with the discovery of novel families (Castellano et al., 2005), the elaboration of novel methods (Taskov et al., 2005; Chapple et al., 2009) and the annotation of different genomes (Jaillon et al., 2004; Drosophila 12 genomes Consortium, 2007; Bovine Genome Sequencing and Analysis Consortium, 2009). Finally, and perhaps most importantly, we have identified the first animal to lack selenoprotein genes (Drosophila 12 genomes Consortium, 2007; Chapple and Guigó, 2008). This last finding is particularly surprising because it had previously been believed that selenoproteins were essential for animal life.
