Now introduce a scientific discovery about this category, Reference of 723-62-6.

A measurement system for cystathionine (Cysta) lanthionine (LT), and S-(2-aminoethyl)-L-cysteine (AEC), and reduced products of their ketimines, perhydro-1,4-thiazepine-3,5-dicarboxylic acid (PHTZDC), 1,4-thiomorpholine-3,5-dicarboxylic acid (TMDA) and 1,4-thiomorpholine-3-carboxylic acid (TMA) in the urine samples of a patient with cystathioninuria and normal human subjects has been developed, using column liquid chromatography-mass spectrometry. The recoveries were about 90-105% for Cysta, LT and AEC, and about 77-87% for PHTZDC, TMDA and TMA after ion-exchange treatment. The concentrations of Cysta and PHTZDC in the urine of a patient with cystathioninuria were much higher compared with those in the urine of normal human subjects. The concentrations of AEC and TMDA were almost the same. LT and TMA could not be detected in the urine samples by this method. This method proved useful for the determination of sulfur-containing amino acids and their cyclic compounds in biological samples. (C) 1997 Elsevier Science B.V.

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. In an article, author is Babic-Samardija, K., once mentioned the application of 1965-09-9, Name is 4,4-Oxydiphenol, molecular formula is C12H10O3, molecular weight is 202.206, MDL number is MFCD00016463, category is thiomorpholine. Now introduce a scientific discovery about this category, Application of 1965-09-9.

Four mixed-ligand cobalt(III) complexes (1-4) of the general formula [Co(Rdtc)cyclam](ClO4)(2) and [Co(Rac)cyclam](ClO4)(2) (cyclam = 1,4,8,11-tetraazacyclotetradecane; Rdtc = thiomorpholine-(Timdtc) or 2-methylpiperidine-(2-Mepipdtc) dithiocarbamates; Rac = 1,1,1,5,5,5-hexafluoro-2,4-pentanedionato (Hfac) or 2,2,6,6-tetramethyl-3,5-heptanedionato (Tmhd), respectively) were electrochemically examined on a glassy carbon and an iron electrode in perchloric acid solution. The obtained results showed the influence of these complexes on hydrogen evolution, the oxygen reduction reaction and iron dissolution. The exhibited effects of the complexes on these reactions depend on structure related to the bidentate dithiocarbamato or beta-diketonato ligand. The electrochemical properties of the complexes were correlated with molecular structure and parameters derived from spectral analysis and molecular modeling.

In a article, author is Haroune, N, introduce new discover of the category.

In situ H-1 NMR, directly performed on biological fluids is a very powerful tool to study the fate of pollutants in the environment. The biodegradation of 2-aminobenzothiazole by Rhodococcus rhodochrous was monitored by reverse phase HPLC and by in situ H-1 NMR, methods performed directly on culture media without purification. The xenobiotic was biotransformed into a hydroxylated derivative. The chemical structure of this metabolite was determined by a long-range H-1-N-15 heteronuclear shift correlation without any previous N-15 enrichment of the compound. This approach allowed the assignment of the metabolite structure to 2-amino-6-hydroxybenzothiazole. (C) 2001 Academie des sciences/Editions scientifiques et medicates Elsevier SAS.

Now introduce a scientific discovery about this category, Application of 589-87-7.

A chelating ligand, 2,6-bis(thiomorpholinomethyl)pyridine (L), was synthesised. Its palladium(II), copper(II) and nickel(II) complexes of the formula ML(NO3)(2), (M = Pd, Cu and Ni), were prepared and characterised. The molecular structures of the three complexes were determined by X-ray diffraction. In all the compounds prepared the ligand acts in a tridentate fashion using its three N atoms while the two S atoms remain free. The Pd complex possesses a distorted square planar coordination geometry with one of the two nitrate groups coordinating as a unidentate ligand and the other ionic. The Pd-N(pyridine) bond length is 1.857(4) Angstrom, which is believed to be the shortest Pd-N separation ever observed. In the Cu complex, the copper atom is five-coordinated in a distorted square planar arrangement with the two nitrate groups acting as unidentate ligands and occupying the apex and one equatorial position. The Ni complex has a distorted octahedral coordination sphere; one nitrate group behaves in a chelating fashion and the other unidentate. (C) 1998 Elsevier Science S.A. All rights reserved.

Herein, we report the stereoselective synthesis of trisubstituted benzoxazino[4,3-b]{1,2,5}thiadiazepinone 6,6-dioxides from polymer-supported Fmoc-Ser(tBu)-OH and Fmoc-Thr(tBu)-OH. After the solid-phase synthesis of N-alkylated-Nsulfonylated intermediates using various 2-nitrobenzenesulfonyl chlorides and bromoketones, the target compounds were obtained via trifluoroacetic acid (TFA)-mediated cleavage from the resin, followed by cyclization of the diazepinone scaffold. Except for the threonine-based intermediates, the inclusion of triethylsilane (TES) in the cleavage cocktail yielded a specific configuration of the newly formed C-3 chiral center. The final cyclization resulted in minor or no inversion of the C-12a stereocenter configuration.

In an article, author is Jovanovic, VM, once mentioned the application of 4180-23-8, Name is (E)-1-Methoxy-4-(prop-1-en-1-yl)benzene, molecular formula is C10H12O, molecular weight is 148.2017, MDL number is MFCD00009284, category is thiomorpholine. Now introduce a scientific discovery about this category, Related Products of 4180-23-8.

Eight mixed-ligand cobalt(III) complexes with the macrocyclic amine 1,4,8,11 -tetraazacyclotetradecane (cyclam) and a heterocyclic dithiocarbamate (Rdtc(-)) i.e., morpholine- (Morphdtc), thiomorpholine- (Timdtc), piperazine- (Pzdtc), N-methylpiperazine- (Mepzdtc), piperidine- (Pipdtc), 2-, 3- or 4-methylpiperidine- (2-, 3- and 4-Mepipdtc) carbodithionato-S,S ions, of the general formula [Co(cyclam)Rdtc](ClO4)(2), were investigated in deoxygenated 0.1 M HClO4 solutions. Cyclic voltammetry data at a glassy carbon (GC) electrode demonstrate a redox reaction of cobalt(III) from the complexes at potentials strongly influenced by the presence of different heterocyclic Rdtc(-) ligands. In this respect, the complexes were separated into two groups: the first, with a heteroatom O, S or N in the heterocyclic ring, and the second, with a methyl group on the piperidine ring of the Rdtc(-) ligand. Anodic polarization of an Fe electrode in the presence of the complexes shows their influence not only on the dissolution of iron but also on the hydrogen evolution reactions and on this basis complexes the complexes could be divided into the same two groups. It was found that the weaker the inhibiting effect of the free heterocyclic amines is, the significantly higher is the efficiency of the corresponding complexes.

Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 15206-55-0, Name is Methyl 2-oxo-2-phenylacetate, molecular formurla is C9H8O3. In a document, author is Diao, Peng-Cheng, introducing its new discovery. Related Products of 15206-55-0.

Based on our previous screening hit compound 1, a series of novel indole-pyrimidine hybrids possessing morpholine or thiomorpholine moiety were synthesized via an efficient one-pot multistep synthetic method. The antiproliferative activities of the synthesized compounds were evaluated in vitro against four cancer cell lines including HeLa, MDA-MB-231, MCF-7, and HCT116. The results revealed that most compounds possessed moderate to excellent potency. The IC50 values of the most promising compound 15 are 0.29, 4.04, and 9.48 mu M against MCF-7, HeLa, and HCI116 cell lines, respectively, which are 48.0, 4.9, and 1.8 folds more active than the lead compound 1. Moreover, fluorescence-activated cell sorting analysis revealed that compound 14 showing the highest activity against HeLa (IC50 = 2.51 mu M) displayed a significant effect on G(2)/M cell-cycle arrest in a concentration-dependent manner in HeLa cell line. In addition, representative nine active hybrids were evaluated for tubulin polymerization inhibitory activities, and compound 15 exhibited the most potent anti-tubulin activity showing 42% inhibition at 10 mu M. These preliminary results encourage a further investigation on indole-pyrimidine hybrids for the development of potent anticancer agents that inhibit tubulin polymerization.
