Fatty acid metabolism in fish species as a biomarker for environmental monitoring

Pollution by Organic Contaminants (OC) in aquatic environments is a relevant issue at the global scale. Lipids comprised of Fatty Acids (FA) play many important roles in the physiology and life history of fishes. Toxic effects of OC are partly dependent on its bioaccumulation in the lipids of aquatic organisms due its physicochemical properties. Therefore, there is an increasing interest to investigate the gene expression as well as the presence and activity of proteins involved in FA metabolism. The attention on Peroxisome Proliferation Activate Receptors (PPARs) also prevails in fish species exposed to OC and in the transport, biosynthesis and beta-oxidation of FA. Several studies have been conducted under controlled conditions to evaluate these biological aspects of fish species exposed to OC, as fibrates, endocrine disrupting compounds, perfluoroalkyl acids, flame retardants, metals and mixtures of organic compounds associated with a polluted area. However, only fibrates, which are agonists of PPARs, induce biological responses suitable to be considered as biomarkers of exposure to these pollutants. According to the documented findings on this topic, it is unlikely that these physiological aspects are suitable to be employed as biomarkers with some noticeable exceptions, which depend on experimental design. This emphasises the need to investigate the responses in fish treated with mixtures of OC and in wild fish species from polluted areas to validate or refute the suitability of these biomarkers for environmental or fish health monitoring.

Comparative photohalogenation of phenylglucopyranoside and its oxidation derivatives

The photobrominations of the peracetylated phenyl thio-1-beta-D-glucopyranoside and of the corresponding sulphoxides and sulphone have been investigated. The differences observed in both substrate reactivity and substitution regioselectivity indicate an easier homolysis of the anomeric C-H bond in the thioglycoside.

Synthesis of N4-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-L-asparagine analogues. L-2-chloro-, L-2-bromo-, and D,L-2-methylsuccinamic acid analogues

L-Chlorosuccinic anhydride, L-bromosuccinic anhydride, and D,L-methylsuccinic anhydride react with 2-acetamido-2-deoxy-beta-D-glucopyranosylamine to give varying mixtures of N4-(beta-GlcNAc)-2-substituted- and N4-(beta-GlcNAc)-3-substituted-succinamic acid isomers. The two regioisomers are separated by anion exchange chromatography. The N4-(beta-GlcNAc)-2-substituted-succinamic acid isomers are characterized as analogues of N4-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-L-asparagine.

Enzymatic syntheses and selective hydrolysis of O-beta-d- galactopyranosides using a marine mollusc beta-galactosidase

The use of crude extract of the hepatopancreas of Aplysia fasciata, a large mollusc belonging to the order Anaspidea containing a beta-galactosidase activity, was reported for the synthesis of different galactosides. Good yields with polar acceptors and the uncommon beta-1-3 selectivity in the transgalactosylation reactions with most of the acceptors were observed. A beta-1-2 selectivity in the hydrolytic conditions was also observed and discussed.

A new dinuclear copper(II) complex [Cu2(mu1,1-NCO) 2(NCO)2(dpyam)2] (dpyam = di-2-pyridylamine) has been synthesized and characterized by X-ray diffraction. Two N-bonded cyanato ligands bridge two copper ions in an end-on fashion and two others act as the N-bonded terminal ligands. The copper ion has a distorted square-pyramidal environment. The magnetic susceptibility, measured from 5 to 300 K, has revealed a weak ferromagnetic interaction between the Cu(II) atoms with a singlet-triplet energy gap (J) of 6.03 cm-1. The EPR spectrum, measured as a powdered solid at RT and 77 K, shows an S = 1/2 signal with g? = 2.08 and an unresolved g? of 2.29.
