• N-Methyltaurine N-acyl amidated bile acids and deoxycholic acid in the bile of angelfish (Pomacanthidae): A novel bile acid profile in Perciform fish.

Electronic address: LHagey@ucsd.edu.AbstractTwo novel N-acyl amidated bile acids, N-methyltaurine conjugated cholic acid and N-methyltaurine conjugated deoxycholic acid, were found to be major biliary bile acids in two species of angelfish the regal (Pygoplites diacanthus) and the blue-girdled (Pomacanthus navarchus) angelfish. The identification was based on their having MS and NMR spectra identical to those of synthetic standards. A survey of biliary bile acids of 10 additional species of angelfish found 7 with N-methyltaurine conjugation. In all 12 species, conjugated deoxycholic acid (known to be formed by bacterial 7-dehydroxylation of cholic acid) was a major bile acid. In all previous studies of biliary bile acids in fish, deoxycholic acid has been present in only trace proportions. In addition, bile acid conjugation with N-methyltaurine has not been detected previously in any known vertebrate. N-methyltaurine conjugated bile acids are resistant to bacterial deconjugation and dehydroxylation, and such resistance to bacterial enzymes should aid in the maintenance of high concentrations of bile acids during lipid digestion. Our findings suggest that these species of angelfish have a novel microbiome in their intestine containing anaerobic bacteria, and describe the presence of N-methyltaurine conjugated bile acids that are resistant to bacterial attack.

• A water-soluble BODIPY derivative as a highly selective "Turn-On" fluorescent sensor for H2O2 sensing in vivo.

Electronic address: sjshao@licp.cas.cn.AbstractA type of BODIPY derivatives was designed and synthesized by the N-alkylation reaction of meso-(4-pyridinyl)-substituted BODIPY. The water-solubility of entire molecule was improved to a large extent as a result of the formation of cationic quaternary ammonium salt, while the strong fluorescence inherent to the BODIPY dye fragment is extinguished on alkylation of the pyridine N atom due to the photo-induced electron transfer (PET) process. The N-alkylated BODIPY derivative 4, as a novel water-soluble "Turn-On" fluorescent probe for the discrimination of H2O2, was constructed by incorporating 4-(Bromomethyl)benzeneboronic acid pinacol ester moiety, which showed highly selective fluorescent response to H2O2 against other interferences of ROS and RNS species under physiological conditions, and the reaction mechanism of boronate oxidation was confirmed by 1H NMR, mass spectrum and optical spectroscopy analysis. As a biocompatible probe in biological systems, probe 4 was successfully applied for monitoring and imaging of H2O2 both in vitro and in vivo using HepG2/LO2 cells and angelfish.

• Effect of low pH exposure on Na(+) regulation in two cichlid fish species of the Amazon.

• Duarte RM, Ferreira MS, Wood CM, Val AL.Author information Brazilian National Institute for Research of the Amazon, Laboratory of Ecophysiology and Molecular Evolution, Ave André Araújo 2936, ZIP 69060-001 Manaus, Amazonas, Brazil. Electronic address: mduarte.rafa@gmail.com.AbstractWe evaluated the effects of acute exposure to low pH on Na(+) regulation in two Amazon cichlids collected from natural ion-poor "blackwaters", angelfish (Pterophyllum scalare) and discus (Symphysodon discus). Na(+) uptake kinetic parameters, unidirectional Na(+) fluxes, and net Cl(-) fluxes were determined at pH6.0 and 3.6. At pH6.0, both species presented low unidirectional Na(+) flux rates, with kinetics showing a relatively low affinity for Na(+) (angelfish Km=79, discus Km=268μmolL(-1)), with similar maximum transport capacities (Jmax~535nmolg(-1)h(-1)). Overall, there appeared to be high sensitivity to inhibition by low pH, yet low intrinsic branchial permeability limiting diffusive ion effluxes, resulting in relatively low net loss rates of Na(+), the same strategy as seen previously in other blackwater cichlids, and very different from the strategy of blackwater characids. At low pH, Na(+) uptake in angelfish was inhibited competitively (increased Km=166μmolL(-1)) and non-competitively (decreased Jmax=106nmolg(-1)h(-1)), whereas in discus, only a decrease in Jmax (112nmolg(-1)h(-1)) was statistically significant. An acute reduction in H(+)-ATPase activity, but not in Na(+)/K(+)-ATPase activity, in the gills of angelfish suggests a possible mechanism for this non-competitive inhibition at low pH. Discus fish were more tolerant to low pH than angelfish, as seen by lesser effects of exposure to pH3.6 on unidirectional Na(+) uptake and efflux rates and net Na(+) and Cl(-) loss rates. Overall, discus are better than angelfish in maintaining ionic balance under acidic, ion-poor conditions.
