X-ray structure analysis reveals β-turn mimicry by N-amino-imidazolidin-2-ones.

Ngoc-Duc Doan et al.

Biopolymers, 104(5), 629-635 (2015-03-20)

The conformation of the N-amino-imidazolidin-2-one (Aid) peptidomimetic was investigated using NMR spectroscopy and X-ray crystallography. In solution, the tetrapeptide model p-bromobenzoyl-Aid-l-Phe-N'-iso-propylamide (1) exhibited shielded and solvent exposed amide protons indicative of a turn conformation. In the crystal lattice of 1

Genetic interference with peroxisome proliferator-activated receptor γ in smooth muscle enhances myogenic tone in the cerebrovasculature via A Rho kinase-dependent mechanism.

T Michael De Silva et al.

Hypertension (Dallas, Tex. : 1979), 65(2), 345-351 (2014-11-12)

Myogenic responses by resistance vessels are a key component of autoregulation in brain, thus playing a crucial role in regulating cerebral blood flow and protecting the blood-brain barrier against potentially detrimental elevations in blood pressure. Although cerebrovascular disease is often

Tackling the challenge of selective analytical clean-up of complex natural extracts: the curious case of chlorophyll removal.

Sebastiaan Bijttebier et al.

Food chemistry, 163, 147-153 (2014-06-11)

Alkaline saponification is often used to remove interfering chlorophylls and lipids during carotenoids analysis. However, saponification also hydrolyses esterified carotenoids and is known to induce artifacts. To avoid carotenoid artifact formation during saponification, Larsen and Christensen (2005) developed a gentler

Use of ion-pairing reagent for improving iodine speciation analysis in seaweed by pressure-driven capillary electrophoresis and ultraviolet detection.

Jiannan Sun et al.

Journal of chromatography. A, 1379, 112-117 (2015-01-13)

This study achieved resolution improvement for iodine speciation in the presence of an ion-pairing reagent by a pressure-driven capillary electrophoresis (CE) system. Addition of 0.01mM tetrabutyl ammonium hydroxide (TBAH) as the ion-pairing reagent into the electrophoretic buffer resulted in the

Remarkably regioselective deacylation of cellulose esters using tetraalkylammonium salts of the strongly basic hydroxide ion.

Xueyan Zheng et al.

Carbohydrate polymers, 111, 25-32 (2014-07-20)

Tetraalkylammonium hydroxides have been found to mediate regioselective deacylation of cellulose esters. This deacylation surprisingly shows substantial selectivity for the removal of the acyl groups at O-2/3, affording cellulose-6-O-esters by a simple, efficient one-step process. The mechanism for this deacylation
