Pathophysiology and Treatment of Hyperhomocysteinemia in End-Stage Renal Disease Patients.

Hemodialysis international. International Symposium on Home Hemodialysis

Sunder-Plassmann G, Hörl WH.
PMID: 28452434
Hemodial Int. 2001 Jan;5(1):86-91. doi: 10.1111/hdi.2001.5.1.86.

The pathophysiology of hyperhomocysteinemia in end-stage renal disease (ESRD) patients includes impaired remethylation of homocysteine (Hcy) to methionine, inhibition of extrarenal Hcy metabolism by uremic solutes, a block in decarboxylation of cysteinesulfinic acid, impaired [adenosylmethionine]/[adenosylhomocysteine] ratio, and a probable...

Journal of the American Chemical Society

Schäfer M, Beattie NA, Geetharani K, Schäfer J, Ewing WC, Krahfuß M, Hörl C, Dewhurst RD, Macgregor SA, Lambert C, Braunschweig H.
PMID: 27286231
J Am Chem Soc. 2016 Jul 06;138(26):8212-20. doi: 10.1021/jacs.6b04128. Epub 2016 Jun 27.

Di-tert-butyliminoborane is found to be a very useful synthon for the synthesis of a variety of functionalized 1,4-azaborinines by the Rh-mediated cyclization of iminoboranes with alkynes. The reactions proceed via [2 + 2] cycloaddition of iminoboranes and alkynes in...

Nano Lett. 2015 Nov 11;15(11):7726-30. doi: 10.1021/acs.nanolett.5b03780. Epub 2015 Oct 28.

Electron tomography in combination with electron energy-loss spectroscopy (EELS) experiments and simulations was used to unravel the interplay between structure and plasmonic properties of a silver nanocuboid dimer. The precise 3D geometry of the particles fabricated by means of...

A theoretical study of the aromaticity in neutral and anionic borole compounds.

Dalton transactions (Cambridge, England : 2003)

Jimenez-Halla JO, Matito E, Solà M, Braunschweig H, Hörl C, Krummenacher I, Wahler J.
PMID: 25494445
Dalton Trans. 2015 Apr 21;44(15):6740-7. doi: 10.1039/c4dt03445g.

In this contribution, we have evaluated the (anti)aromatic character of thirty-four different borole compounds in their neutral and reduced states based on two aromaticity indices, namely nucleus-independent chemical shift (NICS) and multicenter indices (MCI), calculated at the PBE0/6-31+G(d,p) level...

Nonsteroidal Anti-Inflammatory Drugs and the Kidney.

Pharmaceuticals (Basel, Switzerland)

Hörl WH.
PMID: 27713354
Pharmaceuticals (Basel). 2010 Jul 21;3(7):2291-2321. doi: 10.3390/ph3072291.

Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the isoenzymes COX-1 and COX-2 of cyclooxygenase (COX). Renal side effects (e.g., kidney function, fluid and urinary electrolyte excretion) vary with the extent of COX-2-COX-1 selectivity and the administered dose of these compounds. While...

Ansa-Complexes of [Mn(η(5) -C5 H5 )(η(6) -C6 H6 )]: Preparation, Characterization, and Reactivity of [n]Manganoarenophanes (n=1, 2, 3).

Chemistry (Weinheim an der Bergstrasse, Germany)

Braunschweig H, Damme A, Dück K, Fuß M, Hörl C, Kramer T, Krummenacher I, Kupfer T, Paprocki V, Schneider C.
PMID: 26387512
Chemistry. 2015 Oct 12;21(42):14797-803. doi: 10.1002/chem.201502161. Epub 2015 Aug 31.

We report the synthesis of [n]manganoarenophanes (n=1, 2) featuring boron, silicon, germanium, and tin as ansa-bridging elements. Their preparation was achieved by salt-elimination reactions of the dilithiated precursor [Mn(η(5) -C5 H4 Li)(η(6) -C6 H5 Li)]⋅pmdta (pmdta=N,N,N',N',N''-pentamethyldiethylenetriamine) with corresponding element...

Reversible photochemical and thermal isomerization of azaboratabisnorcaradiene to azaborabenzotropilidene.

Angewandte Chemie (International ed. in English)

Rao YL, Hörl C, Braunschweig H, Wang S.
PMID: 24943291
Angew Chem Int Ed Engl. 2014 Aug 18;53(34):9086-9. doi: 10.1002/anie.201404435. Epub 2014 Jun 18.

Two new tricyclic 1,2-azaboratabisnorcaradiene molecules (1 b and 2 b) generated through the photoisomerization of N-methyl-2-phenylimidazolyl-chelated dimesitylboranes (1 a and 2 a) have been found to undergo unusual photoisomerization, producing the first examples of 1,2-azaborabenzotropilidenes (1 c and 2...

Investigating the adsorption of 2-mercaptothiazoline on activated carbon from aqueous systems.

Journal of colloid and interface science

PMID: 23939930
Chemistry. 2013 Sep 27;19(40):13396-401. doi: 10.1002/chem.201302201. Epub 2013 Aug 12.

Chemical single-electron reduction of 1-mesityl-2,3,4,5-tetraphenylborole (3) gave a stable radical anion [CoCp*2 ][3] as shown in earlier investigations. Herein, we present the reaction of [CoCp*2 ][3] with the 2,2,6,6-tetramethylpiperidine-N-oxyl radical (TEMPO), a common radical trap. Instead of radical recombination,...
