Metal ion dyshomeostasis is hypothesized to play a role in the toxicity and aggregation of the amyloid beta (A beta) peptide, contributing to Alzheimer’s disease (AD) pathology. We report on the synthesis and metal complexation ability of three bidentate quinoline-triazole derivatives 3-(4-(quinolin-2-yl)-1H-1,2,3-triazol-1-yl)propan-1-ol (QOH), 4-(2-(4-(quinolin-2-yl)-1H-1,2,3-triazol-1-yl)ethyl)morpholine (QMorph), and 4-(2-(4-(quinolin-2-yl)-1H-1,2,3-triazol-1-yl)ethyl)thiomorpholine (QTMorph). We further study the utility of these ligands to modulate A beta peptide aggregation processes in the presence and absence of Cu2+ ions. Ligand-peptide interactions were first investigated using both 2-D H-1-N-15 band-selective optimized flip angle short transient heteronuclear multiple quantum correlation (SOFAST-HMQC) NMR spectroscopy and molecular modeling techniques, indicating interactions with glutamic acid (E3) and several residues in the hydrophobic region of A beta. Native gel electrophoresis with western blotting along with transmission electron microscopy provided information on the ability of each ligand to modulate A beta aggregation. While the ligands alone did not modify A beta peptide aggregation at the 24 h timepoint, signifying relatively weak ligand-peptide interactions, the ligands did modify the aggregation profile of the peptide in the presence of stoichiometric and suprastoichiometric Cu. Interestingly, the thioether derivative QTMorph exhibited the most pronounced effect on peptide aggregation in the presence of Cu. Overall, the quinoline-triazole ligand series were shown to interact with the hydrophobic region of the A beta peptide, and modulate the Cu-A beta aggregation process. (c) 2016 Elsevier Inc.

New Advances in Chemical Research, May 2021. We’ll be discussing some of the latest developments in chemical about CAS: 723-62-6. In an article, author is Munro, AP, once mentioned the application of 723-62-6, Name is Anthracene-9-carboxylic acid, molecular formula is C15H10O2, molecular weight is 222.2387, MDL number is MFCD00001257, category is thiomorpholine. Now introduce a scientific discovery about this category, Application of 723-62-6.

We report the results of a kinetic study of the reactions of a number of nitrogen nucleophiles with the nitrosothiol S-nitrosopenicillamine (SPEN). The range of nucleophiles includes primary, secondary and tertiary aliphatic amines, together with hydrazine, hydroxylamine, azide ion, ammonia, semicarbazide, thiomorpholine and S-methylcysteine. Secondary amines form N-nitrosamines quantitatively. As expected, reaction occurs via the free base forms of the nucleophiles and consequently most of the reactions take place readily only at relatively high pH. Experiments were carried out with [nucleophile] much greater than [RSNO], and for many reactions, plots of the first order rate constant vs. [nucleophile] were linear. For ammonia and the primary amines, however, this plot tended to level off at high [nucleophile] and an explanation is offered involving the reversible formation of an inactive RSNO-amine complex, for which there is spectral evidence, in parallel with the main reaction. For the secondary amines there is a reasonably good Bronsted plot with a beta value of approximate to 0.2. The much greater reactivities of S-methylcysteine and thiomorpholine, compared to those of primary amines and morpholine respectively are consistent with initial attack at the sulfur atom, followed by an internal rearrangement. Over the whole range of nucleophiles studied there is a reasonable correlation with the Ritchie N+ parameter, and not with the Pearson n scale. Comparisons are made with the corresponding reactions of alkyl nitrites and N-methyl-N-nitrosotoluene-p-sulfonamide (MNTS).

Application of 723-62-6, This is the end of this tutorial post, and I hope it has helped your research about 723-62-6.

Now introduce a scientific discovery about this category, COA of Formula: https://www.ambeed.com/products/455-14-1.html.

The title compound, C19H29NO4S, was synthesised from 9 alpha-hydroxyparthenolide (9 alpha-hydroxy-4,8-dimethyl-12-methylene-3,14-dioxatricyclo[9.3.0.0(2,4)]tetradec-7-en-13-one), which was isolated from the chloroform extract of the aerial parts of the plant Anvillea radiata. The molecule is built up from two fused five-and ten-membered rings, with an additional epoxy ring system and a thiomorpholine group as a substituent. The ten-membered ring adopts an approximate chair-chair conformation, while the thiomorpholine ring displays a chair conformation and the five-membered ring has an envelope conformation, with the C atom closest to the hydroxy group forming the flap. An intramolecular O-H center dot center dot center dot N hydrogen bond closes an S(8) ring. The crystal structure features weak C-H center dot center dot center dot O hydrogen-bonding interactions, which link the molecules into [010] chains.

Reactions of secondary cyclic amines (piperidine, morpholine, thiomorpholine, 1lambda(6), 4-thiazinane-1,1-dione) with trifluoromethanesulfonic anhydride or with N-phenyltriflimide both in the presence and in the absence of a base (Et3N) result in formation of corresponding triflamides and triflates of the initial amines. The triflates and triflamides can be distinguished by their F-19 and N-15 NMR spectra and the presence in the IR spectra of salts of absorption bands in the region 3270-3000 cm(-1) lacking in the spectra of triflamides.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process., Application of 3695-77-0, 3695-77-0, Name is Triphenylmethanethiol, molecular formula is C19H16S, belongs to thiomorpholine compound. In a document, author is Sharma, Meenakshi, introduce the new discover.

An unusually nonplanar, ruffled structure that had been suspected for the previously reported [2,3-bismethylenethiomorpholinochlorinato] nickel (II) complex was confirmed by determination of its crystal structure. Treatment of this thiomorpholinochlorin with acid converts the exocyclic double bonds to direct links to the ortho-positions of both adjacent meso-phenyl groups. The crystal structure of this product indicated that the introduction of these linkages did not change the overall conformation of the macrocycle. The reactivity of the bis-linked thiomorpholine moiety with respect to Raney-nickel-induced (hydro)desulfurization reactions was probed, forming a bis-phenyl-linked 2,3-dimethylchlorin, also characterized by X-ray diffraction, and a bis-indeneannulated porphyrin. We also report on the synthesis of the oxygen analogue to the bis-linked thiomorpholine by reaction of a secochlorin bisketone nickel complex with Woollins’ reagent. We thus introduce novel methodologies toward the synthesis of porphyrinoids carrying beta-to-ortho-phenyl fusions and expand on the scope and limits of the chemistry and interconversion of pyrrole-modified porphyrins.

New dithiocarbamate (dtc) complexes of the form [(PhHg)(2)L] (L = bis(furfurylaminomethyl)benzene dtc L1 (1)), [PhHg(L)] (L = ethyl-1-piperazinecarboxylate dtc L2 (2), thiomorpholine dtc L3 (3), N-(N-methyl-2-pyrrole)-N-(methyl-3-pyridyl) dtc L4 (4), N-(N’-methyl-2-pyrrole)-N-(methyl-benzyl) dtc L5 (5)) and [Hg(L)(2)] (L = bis(N-methyl-3-pyridyl) dtc L6 (6), L4 (7), L5 (8)) have been synthesized and fully characterised; their structures revealed by X-ray crystallography. 1-5 show similar structures with the metal atoms forming two strong bonds, to carbon and one sulfur atom from the bidentate ligand in an approximate linear arrangement with an additional weak bond to the second sulfur atom. However the complexes show very different packing arrangements. 1 is a less common type of dinuclear organomercury complex containing two dithiocarbamate units linked by a 1,4-dibenzyl group. In 6, the metal lies at the centre of a distorted square plane coordinated by two L6 ligands, axially bonded by sulfur atoms on the adjacent molecules in a 2-D polymeric chain. In 7 and 8 the Hg atom is tetrahedrally coordinated to four sulfur atoms from two bidentate ligands. Complexes 2, 5, 7 and 8 show luminescence in solution. (C) 2014 Elsevier B.V.
