Name: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, is researched, Molecular C10H16O4, CAS is 560-09-8, about Synthesis, characterisation and biological activity of chiral platinum(II) complexes. Author is Jaramillo, David; Buck, Damian P.; Collins, J. Grant; Fenton, Ronald R.; Stootman, Frank H.; Wheate, Nial J.; Aldrich-Wright, Janice R..

Four Pt(II) complexes of 1,10-phenanthroline (phen) and 3,4,7,8-tetramethyl-1,10-phenanthroline (3,4,7,8-Me4phen), with the chiral ancillary ligands (1R,3S)- and (1S,3R)-1,3-diamino-1,2,2-trimethylcyclopentane (R,S-tmcp and S,R-tmcp, resp.) were synthesized and their biol. activity quantified using an in vitro cytotoxicity assay against the L1210 murine leukemia cell line. [Pt(R,S-tmcp)(3,4,7,8-Me4phen)]Cl2 and [Pt(S,R-tmcp)(3,4,7,8-Me4phen)]Cl2 showed an increase in biol. activity over their nonmethylated complexes, [Pt(R,S-tmcp)(phen)]Cl2 and [Pt(S,R-tmcp)(phen)]Cl2. Some chiral discrimination was observed in the in vitro cytotoxicity experiments with the complexes having (S,R) configuration showing higher biol. activity in L1210 cells. Titrations of the metal complexes into ct-DNA and observation of the changes induced in the CD spectra were used to determine the binding constants The binding of these metal complexes to the hexamer d(GTCGAC)2 was studied using two-dimensional 1H NMR spectroscopy. The addition of metal complexes to the hexamer produced upfield shifts of the metal complex of selected resonances, characteristic of intercalation for [Pt(tmcp)(phen)]Cl2, whereas the [Pt(tmcp)(3,4,7,8-Me4phen)]Cl2 complexes only partially intercalate and in a side-on fashion. Through the observation of NOE cross-peaks, two-dimensional NMR experiments provided some insight into the site and groove preferences of these complexes when binding to DNA. Here, the authors report the biol. activity of Pt(II) complexes containing an intercalator and a chiral diamine, which influences the degree to which the complexes can interact with DNA.

Formula: Al2H8O13S3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Dielectric measurements in the early stages of hardening of monomineral binders. Author is Svatovskaya, L. B.; Shiballo, V. G..

The dielec. permeability ε of cement hardening systems decreased immediately after preparing suspensions and condensation structures with water were formed having a lower ε. At the end of the hardening process, ε remained constant Because only a small part of the water was chem. bound, the decrease in ε could be connected with the orientation effect. The curves of dielec. losses of the hardening pastes had a complex cyclic character. According to crystallo-optical data, the cyclic character was connected with changes in the phase composition of 3CaO.Al2O3,3CaO.SiO2, and Al2(SO4)3 hydrates and in the 3CaO.Al2O3 + CaSO4 system with the discontinuities of hydrated sulfate aluminate and hydrated aluminate layers.

The NMR of BeSO4.4H2O, Al2(SO4)3.18H2O and of the products of their dehydration were determined Some details of the NMR spectra of MgSO4.7H2O and its dehydration products were also investigated. Substantial increase of the interproton distance was observed in all the sulfates studied possessing low amounts of H2O. This phenomenon is explained by the strong polarization of the H2O mols. and by expansion of the O-H bonds.

The effect of shear history on the evolution of the polystyrene-alum floc size, d., and structure is investigated by small-angle light scattering during cycled-shear and tapered-shear flocculation in a stirred tank using a Rushton impeller. First, various sampling schemes are exptl. evaluated. The floc structure is characterized by the mass fractal dimension, Df, and the relative floc d. During turbulent shear flocculation, small floc structures are shown to be more open (Df=2.1) than larger floc structures (Df=2.5) as a result of shear-induced restructuring during steady state attainment. Flocs produced by cycled-shear flocculation are grown at shear rate G=50 s-1 for 30 min, are fragmented at Gb=100, 300, or 500 s-1 for one minute, and then are regrown at G=50 s-1. This shear schedule decreases the floc size but compacts the floc structure. When flocs are produced by gradual reduction of the shear rate from G=300 to 50 s-1 (tapered-shear flocculation), smaller though equally dense flocs are produced compared with cycled-shear flocculation. The cycled-shear flocculation method produces the largest flocs with the highest potential for sedimentation when the fragmentation shear rate is Gb=300 s-1.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid(SMILESS: CC1(C)[C@@H](CC[C@]1(C)C(O)=O)C(O)=O,cas:560-09-8) is researched.Name: (R)-Piperidin-3-ol hydrochloride. The article 《Oriented Circular Dichroism Analysis of Chiral Surface-Anchored Metal-Organic Frameworks Grown by Liquid-Phase Epitaxy and upon Loading with Chiral Guest Compounds》 in relation to this compound, is published in Chemistry – A European Journal. Let’s take a look at the latest research on this compound (cas:560-09-8).

Oriented CD (OCD) is explored and successfully applied to study chiral surface-anchored metal-organic frameworks (SURMOFs) based on camphoric acid (D- and Lcam) [Cu2(Dcam)2x(Lcam)2-2x(dabco)]n (dabco = 1,4-diazabicyclo-[2.2.2]-octane). The three-dimensional chiral SURMOFs with high-quality orientation were grown on quartz glass plates by using a layer-by-layer LPE method. The growth orientation, as determined by XRD, could be switched between the [001] and [110] direction by using either OH- or COOH-terminated substrates. These SURMOFs were characterized by using OCD, which confirmed the ratio as well as the orientation of the enantiomeric linker mols. Theor. computations demonstrate that the OCD band intensities of the enantiopure [Cu2(Dcam)2(dabco)]n grown in different orientations are a direct result of the anisotropic nature of the chiral SURMOFs. Finally, the enantiopure [Cu2(Dcam)2(dabco)]n and [Cu2(Lcam)2(dabco)]n SURMOFs were loaded with the two chiral forms of Et lactate [(+)-ethyl-D-lactate and (-)-ethyl-L-lactate]. An enantioselective enrichment of >60% was observed by OCD when the chiral host scaffold was loaded from the racemic mixture

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds.

Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Effects of milling of starting hydrated aluminum sulfate on η → α phase transformation and sinterability of alumina. Author is Daimon, Keiji; Kato, Etsuro.

The effects of milling of the precursor, Al2(SO4)3 (14-18)H2O, on η → α phase transformation and sinterability of α-Al2O3 were studied. Milling of the hydrated sulfate lowered the temperatures of dehydration, desulfation, and η → α phase transformation by about 30°, 20°, and 100°, resp. Dehydration of hydrated sulfate produced broken-eggshell-like anhydrous sulfate particles through melting of the hydrate in its water of crystallization On heating, the milled hydrated sulfate converted to anhydrous particles composed of finer sulfate particles. The anhydrous sulfate desulfated into aggregate grains of η-Al2O3 with an irregular pore size distribution. This η-Al2O3, finally formed skeletal grains of α-Al2O3 in which many cracks were produced. The optimum calcination temperature to prepare α-Al2O3 powder for sintering was lowered and the sinterability was improved by the milling treatment. The slope of Avrami-plots for η → α phase transformation indicated a 2-dimensional growth of α-Al2O3. The apparent activation energy for the transformation was 110 kcal/mol, which remained unchanged with milling. The enhancement of η → α phase transformation was due to accelerated nucleation in η-Al2O3 grains, and the sinterability of the α-Al2O3 was improved by an increase in the d. of green compacts, resulting from the occurrence of many cracks in the skeletal grains of α-Al2O3.
