Serum D-serine accumulation after proximal renal tubular damage involves neutral amino acid transporter Asc-1

Chiral separation has revealed enantio-specific changes in blood and urinary levels of amino acids in kidney diseases. Blood D-/L-serine ratio has been identified to have a correlation with creatinine-based kidney function. However, the mechanism of distinctive behavior in serine enantiomers is not well understood. This study was performed to investigate the role of renal tubules in derangement of serine enantiomers using a mouse model of cisplatin-induced tubular injury. Cisplatin treatment resulted in tubular damage histologically restricted to the proximal tubules and showed a significant increase of serum D-/L-serine ratio with positive correlations to serum creatinine and blood urine nitrogen (BUN). The increased D-/L-serine ratio did not associate with activity of a D-serine degrading enzyme, D-amino acid oxidase, in the kidney. Screening transcriptions of neutral amino acid transporters revealed that Asc-1, found in renal tubules and collecting ducts, was significantly increased after cisplatin-treatment, which correlates with serum D-serine increase. In vitro study using a kidney cell line showed that Asc-1 is induced by cisplatin and mediated influx of D-serine preferably to L-serine. Collectively, these results suggest that cisplatin-induced damage of proximal tubules accompanies Asc-1 induction in tubules and collecting ducts and leads to serum D-serine accumulation.

The synthesis of densely functionalised alpha-acyloxy enaminals and enaminones via a novel homogeneous silver(i) catalysed rearrangement

A synthesis of densely functionalised alpha-acyloxy enaminals and enaminones via a novel homogeneous silver(i) catalyzed rearrangement of 1-acyloxy-3-azido ketones is reported. This silver catalyzed reaction involves an internal redox process comprised of four net transformations: loss of nitrogen, reductive cleavage of the azide, 1,2-acyl migration and oxidation of the acyloxy position to an aldehyde (enaminal) or ketone (enaminone). These mild reaction conditions have been applied to acyclic, cyclic, and chiral substrates yielding the rearranged enaminals or enaminones in up to 91% yield, all of which prove to be stable, isolatable products.

Microbial biosynthesis and in vivo depolymerization of intracellular medium-chain-length poly-3-hydroxyalkanoates as potential route to platform chemicals

Biosynthesis and in vivo depolymerization of intracellular medium-chain-length poly-3-hydroxyalkanoates (mcl-PHA) in Pseudomonas putida Bet001 grown on lauric acid were studied. Highest mcl-PHA fraction (>50 % of total biomass) and cell concentration (8gL(-1)) were obtained at carbon-to-nitrogen (C/N) ratio 20, starting cell concentration 1gL(-1), and 48H fermentation. The mcl-PHA comprised of 3-hydroxyhexanoate (C-6), 3-hydroxyoctanote (C-8), 3-hydroxydecanoate (C-10), and 3-hydroxydodecanoate (C-12) monomers. In vivo action was studied in a mineral liquid medium without carbon source, and in different buffer solutions with varied pH, molarity, ionic strength, and temperature. The monomer liberation rate reflected the mol percentage distribution of the initial polymer subunit composition. Rate and percentage of in vivo depolymerization were highest in 0.2M Tris-HCl buffer (pH 9, strength=0.2M, 30 degrees C) at 0.21gL(-1)H(-1) and 98.6 +/- 1.3 wt%, respectively. There is a congruity vis-a-vis to specific buffer type, molarity, pH, ionic strength, and temperature values for superior in vivo depolymerization activities. Direct products from in vivo depolymerization matched the individual monomeric composition of native mcl-PHA. It points to exo-type reaction for the in vivo process, and potential biological route to chiral molecules.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 26544-38-7 is helpful to your research. COA of Formula: C16H26O3.

Proton Sponge Analogue of the Troger’s Base: A Compound with Remarkable Enantiomeric Stability

Proton sponge analogue of the Troger’s base (4) has been obtained upon treatment of 1-amino-4,5-bis(dimethylamino)naphthalene with paraformaldehyde. It was found that in contrast to classical Troger’s base 1, protonation of 4 occurs, at least thermodynamically, exclusively on peri-NMe2 groups producing a dication with two chelated [NHN](+) hydrogen bonds. This prevents the protonation of the bridge nitrogen atoms, which is responsible for rather easy racemization of 1. Indeed, two enantiomers of 4 were resolved by chiral chromatography and their much higher stability in acidic media as compared to 1 has been confirmed. Some other properties of base 4 including structure, basicity, dynamic NMR behavior, host-guest interactions and reactions with electrophiles are also discussed.

Metal-Catalyzed (4+3) Cyclization of Vinyl Aziridines with para-Quinone Methide Derivatives

The development of (4 + 3) cyclizations of vinyl aziridines, especially catalytic asymmetric versions, is needed in organic synthesis. This report describes an iridium-catalyzed (4 + 3) cyclization of vinyl aziridines with paraquinone methide (p-QM) derivatives, and this reaction constructs a seven-membered benzoxazepine scaffold in moderate to high yields (40% to 96%) and considerable diastereoselectivities (70:30 dr to >95:5 dr). Moreover, the catalytic asymmetric version of this (4 + 3) cyclization is accomplished in the presence of a palladium catalyst and a chiral ligand, and this modification provides chiral benzoxazepine derivatives in generally moderate diastereoselectivities (73:27 dr to 91:9 dr) and high enantioselectivities (92:8 to 96:4 er). This approach delivers a scarcely reported catalytic enantioselective (4 + 3) cyclization of vinyl aziridines and offers a metal-catalyzed (4 + 3) cyclization of p-QM derivatives.

Construction of Quaternary Carbon Center by Catalytic Asymmetric Alkylation of 3-Arylpiperidin-2-ones Under Phase-Transfer Conditions

A highly enantioselective synthesis of delta-lactams having a chiral quaternary carbon center at the alpha-position has been developed through an asymmetric alkylation of 3-arylpiperidin-2-ones under phase-transfer conditions. In this transformation, a 2,2-diarylvinyl group on the delta-lactam nitrogen atom plays a crucial role as a novel protecting group and an achiral auxiliary for improving both yield and enantioselectivity of the reaction.

Ritter-enabled catalytic asymmetric chloroamidation of olefins

Intermolecular asymmetric haloamination reactions are challenging due to the inherently high halenium affinity (HalA) of the nitrogen atom, which often leads to N-halogenated products as a kinetic trap. To circumvent this issue, acetonitrile, possessing a low HalA, was used as the nucleophile in the catalytic asymmetric Ritter-type chloroamidation of allyl-amides. This method is compatible with Z and E alkenes with both alkyl and aromatic substitution. Mild acidic workup reveals the 1,2-chloroamide products with enantiomeric excess greater than 95% for many examples. We also report the successful use of the sulfonamide chlorenium reagent dichloramine-T in this chlorenium-initiated catalytic asymmetric Ritter-type reaction. Facile modifications lead to chiral imidazoline, guanidine, and orthogonally protected 1,2,3 chiral tri-amines.
