Effect of metal-metal interactions on electron transfer: An STM study of one-dimensional metal string complexes

Linear metal string complexes of [MnL4(NCS)2] (Scheme 1, M = NiII, CoII, or CrII; n = 3 or 5; L = dpa- or tpda2- where dpa- is dipyridylamido anion and tpda2- is tripyridyldiamido dianion) are studied for the fundamental understanding of the effect of inter-nuclei interactions on electron transfer (ET). The metal strings are isolated within n-alkanethiol monolayers and the properties of ET through various metal strings are differentiated by scanning tunneling microscopy. Although very similar in physical dimension, their apparent heights against the same alkanethiol background are significantly different. The discrepancy is ascribed to electron localization-delocalization among the metal centers.

Effect of cobalt(II) complexes with dipyridylamine and salicylaldehydes on cultured tumor and non-tumor cells: Synthesis, crystal structure investigations and biological activity

The synthesis of eight mixed-ligand cobalt(II) complexes with 2,2?-dipyridylamine (dpamH) and substituted salicylaldehydes (X-saloH) was undertaken in an effort to discover new compounds with anticancer activity. The complexes with the general formula [Co(dpamH)2(X-salo)]Y, (Y = Br or Cl) were characterized by elemental analyses, FT-IR and UV-visible spectroscopy, magnetic and conductivity measurements. The structures of two of them [Co(dpamH)2(5-CH3-salo)]Br and [Co(dpamH) 2(3-OCH3-salo)]Cl, as well as of the precursors [Co(dpamH)3]Br2 and [Co(dpamH)2Cl(H 2O)]Cl, were determined by X-ray crystallography revealing octahedral coordination of cobalt(II) and mononuclear complexes. The complexes were thermally stable up to 200 C in nitrogen atmosphere, studied by simultaneous TG/DTG-DTA technique. The two precursor Co compounds, as well as four of the title compounds, were evaluated for their efficacy as anticancer agents against different cancer and normal human cell lines. The in vitro chemosensitivity of various human cell lines to these Co complexes was evaluated by measuring cell growth inhibition by employing the SRB colorimetric assay. A series of experiments showed a dose-dependent cytotoxic activity of the complexes against all cell lines used. These findings represent a prompting to search for possible interaction of these complexes with other cellular elements of fundamental importance in cell proliferation.

Stereoselective ring-opening of acetylated pyranose-1,2-(ethyl orthoacetates)

When acetylated pyranose-1,2-(ethyl orthoacetates) were hydrolyzed in acidic solvents, the ring-opening of the orthoacetate rings was influenced by the axial or equatorial OAc group at C-4 on the pyranoses; on acid-catalyzed hydrolysis, 3,4,6-tri-O-acetyl-alpha-D-galactopyranose- (8) and methyl 3,4-di-O-acetyl-alpha-D-galacturonatopyranose-1,2-(ethyl orthoacetate) (16) having an axial OAc group at C-4 on the pyranose rings gave 1,3,4,6-tetra-O-acetyl-alpha-D-galactopyranose (9) and methyl 1,3,4-tri-O-acetyl-alpha-D-galacturonatopyranose (23), respectively, whereas 3,4,6-tri-O-acetyl-alpha-D-glucopyranose- (10) and methyl 3,4-di-O-acetyl-alpha-D-glucuronatopyranose-1,2-(ethyl orthoacetate) (22) having an equatorial OAc group at C-4 on the pyranose rings gave 2,3,4,6-tetra-O-acetyl-D-glucopyranose (11) and methyl 2,3,4-tri-O-acetyl-D-glucuronatopyranose (24), respectively. On the acid-catalyzed hydrolysis, 3,4-di-O-acetylbeta-L-arabinopyranose-1,2-(ethyl orthoacetate) (34) having an axial OAc group at C-4 on the pyranose ring gave a mixture of 1,3,4-tri-O-acetyl-beta-L- (35) and 2,3,4-tri-O-acetyl-L-arabinopyranose (36). These selectivities of ring-opening of the 1,2-(orthoacetates) were considered to have resulted from the differences of the conformers of the 1,2-(orthoacids) intermediates derived from the 1,2-(orthoacetates) and the orientation of the acetyl groups at C-4 on the pyranose rings.

Crystal structure of palladium(II) complex with 2,2?-dipyridylamine and 4-toluenesulfonyl-L-serine

The [Pd(dpa)(tsser)] complex (1) is prepared from the reaction of PdCl2 and 2,2?-dipyridylamine (dpa) with 4-toluenesulfonyl-L-serine (tsserH2). This complex is characterized by spectral methods (IR, UV-Vis, 1H NMR, and luminescence), elemental analysis, thermal analysis (TG, DTA), and single crystal X-ray diffraction. X-ray structure determinations show that in this complex, PdII atoms are four-coordinated in a distorted square-planar configuration by two N atoms from a bidentate 2,2?-dipyridylamine ligand and one N atom and one O atom from a bidentate tsser2? ligand.

SYNTHESIS OF GLYCOSYL PHOSPHATES FROM SUGAR ORTHO ESTERS: FORMATION OF BIS(2,3,4,6-TETRA-O-ACETYL-beta-D-GLUCOPYRANOSYL) PHOSPHATE, AND THE EFFECT OF SOLVENTS ON THE SYNTHESIS OF beta-D-GLUCOPYRANOSYL PHOSPHATE

Reaction of exo-3,4,6-tri-O-acetyl-1,2-O-(tert-butyl orthoacetyl)-alpha-D-glucopyranose with phosphoric acid and phosphorus pentaoxide in oxolane gave 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl phosphate.Treatment of the reaction mixture with aqueous lithium hydroxide gave the expected beta-D-glucopyranosyl phosphate.However, neutralization with ammonium hydroxide gave exclusively the phosphoric diester, namely, bis(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl) phosphate.Formation of the diester was traced to the phosphorus pentaoxide in the initial reaction-mixture.A study of solvents showed that phosphorylation of the ortho ester proceeds rapidly in a variety of ethers and N,N-dimethylamides.

A facile transgalactosylation catalyzed by a lipid-coated beta-D-galactosidase in the water-organic two phases

A lipid-coated beta-D-galactosidase could act as an efficient catalyst for transgalactosylation in the water-organic two phases: both the hydrophobic lipid-coated enzyme and alcohols were solubilized in isopropyl ether and mixed with an aqueous solution of lactose (a galactosyl donor). When a native beta-D-galactosidase was employed for the same reaction, neither the transgalactosylation nor the hydrolysis reaction proceeded due to the deactivation of the enzyme at the interface.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10343-06-3 is helpful to your research., Synthetic Route of 10343-06-3

The formation of 3,6-di-O-acetyl-1,2,4-O-orthoacetyl-alpha-d- glucopyranose was observed in the gold(i)-catalyzed glycosidation of peracetyl glucopyranosyl ortho-hexynylbenzoate; experiments with substrates bearing deuterium labeled 2-O-acetyl or 4-O-acetyl groups indicated that the orthoacetate was derived from the 4-O-acetyl group, which provided a direct evidence for the remote participation of the 4-O-acyl group in glycosylation.

Glycosylidene Carbenes Part 5 Synthesis of Glycono-1,5-lactone Tosylhydrazones as Precursors of Glycosylidene Carbenes

The benzyl- and the acyl-protected glyconolactone tosylhydrazones 6, 9, 12, 16, and 19 (Scheme 1) were prepared in good yields by treating the hemiacetals 4, 7, 10, 14, and 17 with N-tosylhydrazine, to give the N-glycosylhydrazines 5, 8, 11, 15, and 18, and by oxidizing these hydrazines with N-bromosuccinimide (NBS) in the presence of 1,8-diazabicyclo<5.4.0>undec-7-ene (DBU), with CrO3-dipyridine complex or with pyridinium dichromate.Photolysis of the sodium salt 20 of 6 (Scheme 2) in the presence of N-phenylmaleimide, dimethyl fumarate, or acrylonitrile gave the corresponding cyclopropanes 21-28 in satisfactory yields.Photolytic or thermolytic glycosidation of phenol and 4-methoxyphenol by 20 yielded the anomeric glycosides 29/30 and 31/32, yields being marginally higher for the thermolytic process.Photolytic glycosidation of propan-2-ol gave the glycosides 33 and 34 in low yields only.Yields and ratios of products were compared to those obtained with the diazirine 1 as a source of glycosylidene carbenes.While the yields from 20 are lower, the ratios of products obtained in the photolytic reactions are in agreement with the formation of a common intermediate from both carbene precursors.
