Maternal Allocation of Lipids to Eggs by Southern Flounder after Diet Changes

Maturation and spawning diets for flatfish broodstock, such as Southern Flounder Paralichthys lethostigma, have received little research attention, despite their critical role in the reproductive performance. During the spawning season, which is when Southern Flounder broodstock produce multiple egg batches, they rely on their diet to supply nutrients to the eggs. Lipids are an important class of nutrients for offspring development. The objective of this brief communication is to describe the changes in egg lipid classes during the spawning season following a diet change. Female broodstock were fed three diets after the first spawn (week 0)-a control diet (equal weights of Spanish Sardines Sardinella aurita and brown shrimp Farfantepenaeus aztecus), a shrimp-only diet, and a sardine-only diet (n = 3, 3, and 4, respectively)-for a period of 6 weeks and the lipid composition of the eggs was measured every 2 weeks. The change to a diet of sardines only or shrimp only altered the concentrations of egg lipid classes, indicating that egg composition is affected by maternal dietary intake over a period of 2 weeks or less. Females that were fed the sardine-only diet produced eggs with higher levels of ketones and acetone-mobile polar lipids and lower levels of hydrocarbons than did females that were fed shrimp, exhibiting changes that were consistent with the differences between the diets. The shift to the sardine-only diet had little effect on total lipids, triacylglycerols, free fatty acids, and sterols in the eggs. The change to the shrimp-only diet resulted in subtle but consistent decreases in all of the lipids, except wax/steryl esters at week 2, followed by gradual increases. This suggests that the shrimp-only diet provided insufficient nutrition and that the females mobilized stored lipids to compensate. These preliminary results revealed interesting patterns that, with further research, could lead to improved diets and feeding protocols for the production of Southern Flounder.

What Does the Bronsted Slope Measure in the Phosphoryl Transfer Transition State?

The structural and energetic features of phosphate and phosphonate hydrolysis in protein phosphatase-1 (PP1) and water are studied using quantum mechanical (QM) cluster models. The calculations are able to reproduce observed kinetic isotope effects and capture several key trends in the experimental Brmnsted plots: the (beta)lg values are rather different for phosphate and phosphonate ester hydrolysis in solution but are similar in PP1. Detailed analyses of the structures, charge distributions, and bond orders of computed transition states support the general conclusion from experimental study that phosphoryl transfer transition states are different for the two classes of substrates in solution but similar in PP1. On the other hand, the microscopic models also highlight notable differences between the phosphate and phosphonate transition states, which are manifested in not only structure but also kinetic isotope effects. Overall, we find that while beta(lg)/beta(EQ,lg) generally correlates with the partial charge on leaving group oxygen and the fractional bond order of the breaking P-O-lg bond, the precise mapping between beta(lg)/beta(EQ,lg) and P-O-lg bond order in the transition state is difficult due largely to the crosstalk between breaking and forming P-O bonds. Therefore, in further support of previous analyses of the limitations of free energy relations, our results suggest that while the free energy relation is a valuable tool for probing the nature of the transition state, a quantitative mapping of beta(lg) and beta(lg)/beta(EQ,lg )values to structure or charge in the transition state should be conducted with great care.

Conversion of Unprotected Aldose Sugars to Polyhydroxyalkyl and C-Glycosyl Furans via Zirconium Catalysis

An efficient, zirconium-catalyzed conversion of unprotected aldose sugars with acetylacetone to polyhydroxyalkyl furans or C-glycosylfurans is reported. The furan products are formed in up to 93% yield using 5-10 mol % ZrCl4. Pentoses are readily converted at room temperature, while hexoses and their oligosaccharides require mild heating (i.e., 50 degrees C). Efficient conversions of glycolaldehyde, glyceraldehyde, erythrose, a heptose, and glucosamine are also demonstrated. This approach outpaces each of the previous Lewis acid-catalyzed methods in at least one the following ways: (i) lower catalyst loadings; (ii) reduced reaction temperatures; (iii) shorter reaction times; (iv) equimolar substrate stoichiometry; (v) expanded sugar scope; (vi) higher selectivities; and (vii) the use of an Earth-abundant Zr catalyst.

New beta-ketophosphonates for the synthesis of prostaglandin analogues. 2 Phosphonates with bicyclo[3.3.0]octene and bicyclo[3.3.0]octane scaffolds linked to the beta-keto group

beta-Ketophosphonates, with the keto group linked to a bicyclo[3.3.0]oct(a)ene fragment, were synthesized starting from two diacids. These diacids were first transformed into internal anhydrides and one into a diester. The anhydrides and the diester were reacted with the lithium salt of dimethyl methanephosphonate to give two carboxy beta-ketophosphonates, an ester beta-ketophosphonate and a bis beta-ketophosphonate in good yield. The ester beta-ketophosphonate, obtained by two routes was used in the E-HEW selective olefination of a prostaglandin aldehyde with an alpha-side chain to give the 15-keto prostaglandin analogue in good yield. The compounds were characterized by elemental analysis, IR and high resolution H-1- and C-13-NMR spectroscopies.

Chemical Synthesis of Fucosylated Chondroitin Sulfate Oligosaccharides

Fucosylated chondroitin sulfates (FuCSs) are a unique type of polysaccharides occurring in sea cucumber that show a variety of biological activities. In particular, well-defined FuCS oligosaccharides, consisting of a trisaccharide repeating unit of beta-D-GalNAc(4,6-diS)-(1 -> 4)-[alpha-L-Fuc(2,4-diS)-(1 -> 3)]-beta-D-GlcUA, display potent anticoagulant activity via selective inhibition of the intrinsic tenase, which could be developed into anticoagulant drugs without bleeding risk. Herein, we report an effective approach to the synthesis of FuCS oligosaccharides, as demonstrated by the successful elaboration of FuCS tri-, hexa-, and nonasaccharides. The syntheses employ an orthogonally protected trisaccharide as a pivotal building block that can be readily converted into the donor and acceptor for glycosidic coupling. In addition, the internal patterns of protecting groups, involving N-trichloroacetyl for N-acetyl group, benzylidene and benzyl groups for sulfonated hydroxyl groups, and benzoyl and methyl esters for free hydroxyl and carboxylic acid, respectively, ensure stereoselective formation of the glycosidic linkages and sequential transformation into the desired FuCS oligosaccharides.
