A synthetic method to access symmetric and non-symmetric 2-(N,N'-disubstituted)guanidinebenzothiazoles.
Symmetric and non-symmetric 2-(N-H, N-methyl, N-ethylenyl and N-aryl)guanidinebenzothiazoles were synthesized from the reaction of ammonia, methylamine, pyrrolidine and aniline with dimethyl benzo[d]t...Read More
Bond rotations are common and important in molecular studies such as drug design and enzymatic reactions. Steric hindrance and hyperconjugation are often borrowed to justify the origin of bond rotatio...Read More
Vascular Adhesion Protein-1 (VAP-1) is an endothelial adhesion molecule belonging to the primary amine oxidases. Upon inflammation it takes part in the leukocyte extravasation cascade facilitating tra...Read More
Benzylamine antihyperglycemic effect is abolished by AOC3 gene invalidation in mice but not rescued by semicarbazide-sensitive amine oxidase expression under the control of aP2 promoter.
Semicarbazide-sensitive amine oxidase (SSAO) is a transmembrane enzyme that metabolizes primary amines from endogenous or dietary origin. SSAO is highly expressed in adipose, smooth muscle and endothe...Read More
Elucidation of the Role of the Methylene-Tetrahydromethanopterin Dehydrogenase MtdA in the Tetrahydromethanopterin-Dependent Oxidation Pathway in Methylobacterium extorquens AM1.
The methylotroph Methylobacterium extorquens AM1 oxidizes methanol and methylamine to formaldehyde and subsequently to formate, an intermediate that serves as the branch point between assimilation (fo...Read More
We studied the role of peroxisomal catalase in chronological aging of the yeastHansenula polymorpha in relation to various growth substrates. Catalase-deficient (cat) cells showed a similar chronologi...Read More
Photoinduced Proton-Coupled Electron Transfer of Hydrogen-Bonded p-Nitrophenylphenol-Methylamine Complex in Solution.
Proton-coupled electron transfer can occur through concerted (electron-proton transfer, EPT) or sequential mechanisms, but this distinction becomes less well-defined for photoinduced reactions. These ...Read More
Chronological aging of yeast cells is commonly used as a model for aging of human post-mitotic cells. The yeast Saccharomyces cerevisiae grown on glucose in the presence of ammonium sulphate is mainly...Read More
First principles electronic structure calculations are typically performed in terms of molecular orbitals (or bands), providing a straightforward theoretical avenue for approximations of increasing so...Read More
Ammonia is the preferred nitrogen source for many algae including the cyanobacterium Synechococcus elongatis (Synechococcus R-2; PCC 7942). Modelling ammonia uptake by cells is not straightforward bec...Read More
To reach the egg in the ampulla, sperm have to travel along the female genital tract, thereby being dependent on external energy sources and substances to maintain and raise the flagellar beat. The va...Read More
Exploring the properties of small molecule protein binding via molecular simulations: the TRSH-p53 core domain complex.
Molecular dynamics simulations have been performed to investigate the binding of tris(hydroxymethyl)-aminomethane to the surface of the core domain of the mouse cellular tumor antigen p53 employing th...Read More
Ammoniomethyl trifluoroborates are very powerful reagents that can be used to access biologically relevant aryl- and heteroaryl-methylamine motifs via Suzuki-Miyaura cross-couplings. Until now, this m...Read More
Kidney cells of animals including human and marine invertebrates contain high amount of the protein denaturant, urea. Methylamine osmolytes are generally believed to offset the harmful effects of urea...Read More
This study investigated the odor compounds from different areas in a landfill site, which included the municipal solid waste (MSW)-related area, the leachate-related area and the sludge-related area. ...Read More
Single-walled carbon nanotubes (SWCNTs) have been functionalized with highly selective tetraphosphonate cavitand receptors. The binding of charged N-methylammonium species to the functionalized SWCNTs...Read More
Density functional theory study on the interactions between Ni(n) (n = 1,..., 6) and methylamine or acetic acid.
The interactions between methylamine or acetic acid with the Ni(n) (n = 1,...,6) in triplet clusters were examined at the B3LYP/6-31G(d, p) and LANL2TZ+ level. The structural stability, interacting st...Read More
Using density functional theory calculations, we report on the adsorption of methylamine on gold and compare its adsorption to a selection of alkylamines, methanol and methanethiol. On the (111) surfa...Read More
[Purification and characteristics of methanol dehydrogenase of Methylobacterium nodulans rhizosphere phytosymbionts].
Methanol dehydrogenase (MDG) of the facultative methylotrophic phytosymbiont Methylobacterium nodulans has been purified for the first time to an electrophoretically homogeneous state and characterize...Read More
Water adsorption at two unsolvated peptides with a protonated lysine residue: from self-solvation to solvation.
We study the initial steps of the interaction of water molecules with two unsolvated peptides: Ac-Ala(5)-LysH(+) and Ac-Ala(8)-LysH(+). Each peptide has two primary candidate sites for water adsorptio...Read More
A micro trapping system coupled with a high performance liquid chromatography procedure for methylamine determination in both tissue and cigarette smoke.
Both endogenous and exogenous methylamine have been found to be involved in many human disorders. The quantitative assessment of methylamine has drawn considerable interest in recent years. Although t...Read More
Natural Bond Critical Point analysis: quantitative relationships between natural bond orbital-based and QTAIM-based topological descriptors of chemical bonding.
We have developed a "Natural Bond Critical Point" (NBCP) module for the natural bond orbital (NBO) program that allows mutual analysis of NBO-based versus Bader-type quantum theory of atoms ...Read More
Metabonomic analysis of the therapeutic effect of Zhibai Dihuang Pill in treatment of streptozotocin-induced diabetic nephropathy.
