Ternary systems of Cu(II) with phosphocreatine (PCr) and the polyamines (PAs), ethylenediamine (en), 1,3-diaminopropane (tn), putrescine (Put), spermidine (Spd), and spermine (Spm), were studied in aqueous solution through potentiometry, UV-visible, EPR and Raman spectroscopy. The binary complex CuPCr was also studied by Raman spectroscopy, and the calculation of the min. stabilization energy was done assuming this mol. in aqueous solution The stability constants of the CuPCrPA ternary complexes were determined by potentiometry (T = 25¡ã, I = 0.1 mol L^–?¹, KNO₃). The stability order determined was CuPCrSpm > CuPCrSpd > CuPCren > CuPCrtn > CuPCrPut, the same order of the corresponding binary complexes of Cu(II) with these polyamines. The evaluation of intramol. PA-PCr interactions in protonated and deprotonated species of ternary complexes was carried out using the equation ¦¤log K = log ¦Â_CuPCrPAHq?₊?_p – (log ¦Â_CuPAHq + log ¦Â_CuPCrHp). All of the CuPCrPA ternary complexes have a square planar structure and are bonded to PCr through the N atom of the guanidine group and the O atom of the phosphate group, and to the PAs through two N atoms of the amine groups. The structure of the complex CuPCrSpm is planar with distortion towards tetrahedral. Calculation of the min. stabilization energy for the CuPCr and CuPCrenH complexes confirmed the proposed coordination mode.

Matsumura, Hideo published the artcileCoagulation behavior of vesicles composed of crown ethers and phospholipids caused by bolaform surfactants, Category: catalysis-chemistry, the publication is Journal of Colloid and Interface Science (1990), 139(2), 331-6, database is CAplus.

The colloid stability of mixed vesicles composed of two components, a crown ether with a long hydrocarbon chain and a phospholipid, against bolaform surfactants was studied. The critical coagulation concentration of primary ammonium ions of the bolaform for the vesicle is lower than that of corresponding quaternary ammonium ions, which can be attributed to the affinity difference between the two types of terminal ionic groups for the crown ether. The steric bulky effect of bolaform ions on the screening of the surface charges is negligible, but the hydrophobic interaction of a hydrocarbon chain connecting the two terminal ionic parts of the surfactants with the vesicle surface plays a significant role in the vesicle coagulation.

Diaz, Celine published the artcileDetermining novel functions of Arabidopsis 14-3-3 proteins in central metabolic processes, COA of Formula: C3H12Cl2N2, the publication is BMC Systems Biology (2011), 192, database is CAplus and MEDLINE.

Background: 14-3-3 proteins are considered master regulators of many signal transduction cascades in eukaryotes. In plants, 14-3-3 proteins have major roles as regulators of nitrogen and carbon metabolism, conclusions based on the studies of a few specific 14-3-3 targets. Results: In this study, extensive novel roles of 14-3-3 proteins in plant metabolism were determined through combining the parallel analyses of metabolites and enzyme activities in 14-3-3 overexpression and knockout plants with studies of protein-protein interactions. Decreases in the levels of sugars and nitrogen-containing-compounds and in the activities of known 14-3-3-interacting-enzymes were observed in 14-3-3 overexpression plants. Plants overexpressing 14-3-3 proteins also contained decreased levels of malate and citrate, which are intermediate compounds of the tricarboxylic acid (TCA) cycle. These modifications were related to the reduced activities of isocitrate dehydrogenase and malate dehydrogenase, which are key enzymes of TCA cycle. In addition, we demonstrated that 14-3-3 proteins interacted with one isocitrate dehydrogenase and two malate dehydrogenases. There were also changes in the levels of aromatic compounds and the activities of shikimate dehydrogenase, which participates in the biosynthesis of aromatic compounds Conclusion: Taken together, our findings indicate that 14-3-3 proteins play roles as crucial tuners of multiple primary metabolic processes including TCA cycle and the shikimate pathway.

Hasegawa, Miki published the artcileElectronic structure of Cu(II) complexes with N,N’-disalicylidene-1,2-cyclohexanediamine and N,N’-disalicylidenetrimethylenediamine, Name: Propane-1,3-diamine dihydrochloride, the publication is Monatshefte fuer Chemie (2002), 133(3), 285-298, database is CAplus.

The electronic absorption and x-ray photoelectron spectra of N,N’-disalicylidenetrimethylenediaminatocopper(II) ([Cu(saltn)]) and N,N’-disalicylidene-trans-1,2-cyclohexanediaminatocopper(II) ([Cu(salchx)]) were measured. From these results and from informations derived from MO calculations the electronic structure of the complexes was clarified. Each electronic absorption band which can be assigned to the ¦Ð¦Ð^* or ML/LMCT transition of [Cu(saltn)] or [Cu(salchx)] observed in the wavelength region of 450-200 nm appears at the almost same frequency as the corresponding band of N,N’-disalicylideneethylenediaminatocopper(II) ([Cu(salen)]) in solution The LLCT bands (the intramol. CT band between two ¦Ð-electronic systems separated by saturated hydrocarbon chains such as -(CH₂)_n^–) also appear at nearly the same positions (?245 nm) for [Cu(salchx)], [Cu(saltn)], and [Cu(salen)]. The locations of the dd transition and the intensity of the ML/LMCT transition of [Cu(saltn)] are significantly different from those of [Cu(salen)] and [Cu(salchx)]. These differences may arise from the strengths of the interaction between metal and ligand.

Lim, Ae Ran published the artcilePhysicochemical properties and structural dynamics of organic-inorganic hybrid [NH₃(CH₂)₃NH₃]ZnX₄ (X = Cl and Br) crystals, Related Products of catalysis-chemistry, the publication is Scientific Reports (2021), 11(1), 8408, database is CAplus and MEDLINE.

The phys. properties of the organic-inorganic hybrid crystals having the formula [NH₃(CH₂)₃NH₃]ZnX₄ (X = Cl, Br) were investigated. The phase transition temperatures (TC; 268K for Cl and 272K for Br) of the two crystals bearing different halogen atoms in their skeletons were determined through differential scanning calorimetry. The thermodn. properties of the two crystals were investigated through thermogravimetric anal. The structural dynamics, particularly the role of the [NH₃(CH₂)₃NH₃] cation, were probed through ¹H and ¹³C magic-angle spinning NMR spectroscopy as a function of temperature The ¹H and ¹³C NMR chem. shifts did not show any changes near TC. In addition, the ¹H spin-lattice relaxation time (T_1¦Ñ) varied with temperature, whereas the ¹³C T_1¦Ñ values remained nearly constant at different temperatures The T_1¦Ñ values of the atoms in [NH₃(CH₂)₃NH₃]ZnCl₄ were higher than those in [NH₃(CH₂)₃NH₃]ZnBr₄. The observed differences in the structural dynamics obtained from the chem. shifts and T_1¦Ñ values of the two compounds can be attributed to the differences in the bond lengths and halogen atoms. These findings can provide important insights or potential applications of these crystals.

Organic-inorganic hybrid perovskites (OIHs) are exceptionally promising sector of novel materials for optoelectronic applications. Herein, the OIHs of the formula [(NH₃)₂(CH₂)₃]CuCl₄ labeled by C₃CuCl and [(NH₃)₂(CH₂)₄]CuCl₂Br₂ labeled by C₄CuClBr are prepared by slow evaporation method. The synthesis process is achieved by mixing equimolar ethanolic solutions ratios (1:1) of their basic components (organic/inorganic). Characterizations of these materials using microchem. anal., energy dispersion X-ray (EDX) and X-ray diffraction (XRD) are discussed. The XRD is used to estimate the crystalline size for prepared compounds and found in the range of 38.8 and 48.8 nm for C₃CuCl and C₄CuClBr, resp. The vibrational spectra are studied by Fourier transformation IR spectroscopy (FTIR) and show the major diffraction peaks of compounds and their assignment. UV-region strong absorption is clarified in the optical properties studied for Cu hybrid, whereas the bandgap energy estimated via Kubelka-Munk equation and found 2.8 and 3.85 eV for C₃CuCl and C₄CuClBr, resp.

LoCoco, Matthew D. published the artcileChelate-Controlled Synthesis of rac- and meso-Me₂Si(3-^tBu-C₅H₃)₂ZrCl₂, Application In Synthesis of 10517-44-9, the publication is Organometallics (2003), 22(26), 5498-5503, database is CAplus.

The reaction of the chelated bis-amide complex Zr{PhN(CH₂)₃NPh}Cl₂(THF)₂ (2) with Li₂[Me₂Si(3-^tBu-C₅H₃)₂] yields meso-Me₂Si(3-^tBu-C₅H₃)₂Zr{PhN(CH₂)₃NPh} (meso-3) in >98% yield. In contrast, the reaction of Zr{Me₃SiN(CH₂)₃NSiMe₃}Cl₂(THF)₂ (4) or the related mono-THF adduct Zr{Me₃SiN(CH₂)₃NSiMe₃}Cl₂(THF) (5) with Li₂[Me₂Si(3-^tBu-C₅H₃)₂] yields rac-Me₂Si(3-^tBu-C₅H₃)₂Zr{Me₃SiN(CH₂)₃NSiMe₃} (rac-6) in quant. NMR yield and 89% isolated yield. X-ray crystallog. analyses show that the Zr{RN(CH₂)₃NR} chelate ring in rac-6 has a pronounced twist conformation, while that in meso-3 has a flatter, envelope conformation. It is proposed that the conformations of the Zr{RN(CH₂)₃NR} chelate rings in the stereodetermining transition states for addition of the second Cp^– ring in these reactions are similar to those in the metallocene products and control the diastereoselectivity. Meso-3 and rac-6 are converted to meso-Me₂Si(3-^tBu-C₅H₃)₂ZrCl₂ (meso-1) and rac-1, resp., by reaction with HCl in Et₂O.

Valandro, Silvano R. published the artcileAggregation-Enhanced Two-Photon Absorption of Anionic Conjugated Polyelectrolytes, Product Details of C3H12Cl2N2, the publication is Journal of Physical Chemistry Letters (2020), 11(19), 8292-8296, database is CAplus and MEDLINE.

The two-photon absorption properties of anionic poly(phenylene ethynylene)-type conjugated oligo- and polyelectrolytes are studied in molecularly dissolved and aggregated forms in aqueous solution Several different polyvalent cations are used to induce aggregation. It is found that both materials in the aggregated form exhibit enhanced two-photon excited fluorescence (2PEF) and two-photon cross section (¦Ò₂) compared with the molecularly dissolved structures. The 2PEF and ¦Ò₂ are unaffected by the nature of the polyvalent cation that is used to induce aggregation. The two-photon absorption cross section enhancement arises because of the increase in the difference dipole moment (¦¤¦Ì) in the aggregates of the conjugated materials, an effect that is attributed to the introduction of charge transfer character into the aggregate excited state.

Eggleston, Drake S. published the artcileTetrasubstituted [14]-1,3,8,10-tetraeneN₄ macrocyclic complexes: synthesis, organic precursor, and template reaction mechanism, Computed Properties of 10517-44-9, the publication is Inorganic Chemistry (1980), 19(6), 1593-9, database is CAplus.

Template syntheses have been studied for macrocyclic complexes derived from 1,3-diaminopropane (DAP), 1-phenyl-1,2-propanedione (AB), and metal(II) acetate, where the metal is Fe, Co or Ni. The products were characterized by elemental analyses and conductivity and spectroscopic methods (IR, UV-visible, and ¹H and ¹³C NMR). The ¹³C NMR anal. indicated that the template synthesis is regiospecific, producing only one of the two possible isomeric products corresponding to the ligand 2,9-dimethyl-3,10-diphenyl-1,4,8,11-tetraazacyclotetradeca-1,3,8,10-tetraene, trans-MePhTIM. X-ray diffraction data for a crystal of [Co(MePhTIM)Cl₂]PF₆ are also consistent with a centrosym. trans isomer product. ¹H NMR studies of the 1:1 condensation of AB and DAP in the absence of metals indicates a mixture of products from which the major product was isolated and found to be 2-benzoyl-2-methylhexahydropyrimidine. Reaction of this compound with metal salts yields the isomerically pure trans-MePhTIM complexes. The synthetic results and ¹H NMR studies are consistent with a proposed template mechanism in which AB and DAP react first to form 2-benzoyl-2-methylhexahydropyrimidine in equilibrium with its open-chain Schiff-base tautomer. Subsequent condensation of two of the Schiff-base mols. under the influence of a metal ion leads exclusively to the trans-MePhTIM complex. Results of other experiments and syntheses using an unsym. substituted alkyl ¦Á-diketone indicate that the mechanism is also applicable to related systems.
