A series of gamma-[Glu]((n= 2,3,4))-Val or gamma-[Glu]((n= 2,3,4))-Met were synthesized in the presence of donor (Gln) and corresponding acceptor (Val or Met) through transpeptidation catalyzed by the glutaminase from Bacillus amyloliquefaciens. Gln in excess significantly (p <.05 improved the yield of gamma-> 1))-Val/Met except for gamma-Glu-Val/Met. The Km values for transpeptida...

Due to antitumor and antioxidant activities, there has been increasing interest in fucoidans, sulfated polysaccharides, from brown algae. Currently, the classic hot water extraction and acid extraction are time-consuming, and can cause the partial cleavage of sulfate esters, leading to bioactivity loss. The present study developed a novel process f...

This publication concerns the design of advanced nanostructured inorganic materials using supercritical fluids. A brief overview of the different experimental and numerical tools, which are now available for the scientific community and engineers, is proposed giving access to a better understanding but also a better control on material synthesis. T...

The molecule of the title compound, C13H10ClNO, (I), which contains an intramolecular O—H...N hydrogen bond, is almost planar: the dihedral angle between the two aryl rings is only 3.31 (9)°. The molecules of (I) are linked into sheets by two C—H...π(arene) hydrogen bonds and the sheets are linked into a three-dimensional structure by O—H...O hy...

A series of novel 5–bromo–2-chloropyrimidin-4-amine derivatives ( 7a - h and 8a - e ) were synthesized by nucleophilic substitution reaction with various sulfonyl and acid chlorides. The newly synthesized compounds were characterized by elemental analy- ses, FT-IR, 1 H NMR and LC-MS spectral studies. All compounds were evaluated for its in vitro an...

Tephrosia (Tephrosia Vogelii) is a legume that has about 8% oil plus rotenoids, which has been studied by several authors. This oil was analyzed in the seeds and used for transesterification of triglycerides providing glycerin and biodiesel as major products, which are a mixture of straight-chain alkyl esters. In transesterification, an excess of a...

This work presents developing processes for the recovery formalin and ethanol residues generated in laboratories. Disposal formaldehyde in unknown concentration and ethanol residue 70 ºGL were collected in the zoological conservation laboratory. A simple distillation process for the purification and recovery formalin solution was used. Concerning e...

Nanomaterials constructed by self-assembly of biomolecules are of particular interest as drug delivery carriers in biomedicine. However, supramolecular construction of nanoparticles by self-assembly of highly hydrophilic biomolecules such as hyaluronic acid still remains a formidable challenge due to their water solubility. Herein, we propose a str...

Four kinds of CuO catalysts with well-controlled leaf-like (L-CuO), flower-like (F-CuO), sea-urchin-like (U-CuO), and oatmeal-like (O-CuO) morphologies were synthesized by a facile precipitation method assisted by various chelating ligands. High-resolution transmission electron microscopy and fast Fourier transform infrared spectroscopy indicated t...
