Neutral discrete metal-organic cyclic architectures: Opportunities for structural features and properties in confined spaces

An emerging class of neutral metal-organic supramolecules has led to some fascinating and sophisticated structures including their photophysics and host-guest properties that have attracted the imagination of chemists. Synthetic routes including step-wise and one-step strategies have been employed to achieve the targeting of neutral structures. Several discrete neutral assemblies of various nuclearities, in which the coordination geometries for transition metals include octahedral, tetrahedral, and square planar, integrating main-group elements in supramolecular self-assembly applications allows for the formation of markedly different structural motifs. The structural characteristics of the ligands as well as the metal centers present in the neutral metallacycles allow easy tuning of their emission properties. Therefore, by engineering the different parts in neutral metal-organic ensembles, emissions from blue to red have been achieved. The neutral metallacyclic structures are unique in their well-defined forms and would be expected to function as a macrocycle host with a large internal cavity shapes generated by the tailored ligands. Hence, the presence of both photophysical properties and the cavity sizes of these neutral metallacycles make them intriguing hosts for neutral guests and metal ions. This review provides an overview of the structural features and properties of neutral discrete metal-organic cyclic architectures ranging from binuclear to fascinating multinuclear assemblies that emerged during the period from 2005 to 2012.

Synthesis, characterization, thermal and DNA-binding properties of new zinc complexes with 2-hydroxyphenones

The neutral mononuclear zinc complexes with 2-hydroxyphenones (ketoH) having the formula [Zn(keto)2(H2O)2] and [Zn(keto)2(enR)], where enR stands for a N,N’-donor heterocyclic ligand such as 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen) or 2,2?-dipyridylamine (dpamH), have been synthesized and characterized by IR, UV and 1H NMR spectroscopies. The 2-hydroxyphenones are chelated to the metal ion through the phenolate and carbonyl oxygen atoms. The crystal structures of [bis(2-hydroxy-4-methoxy-benzophenone)(2,2?-bipyridine) zinc(II)] dimethanol solvate and [bis(2-hydroxy-benzophenone)(2,2?- bipyridine)zinc(II)] dimethanol solvate have been determined by X-ray crystallography. The thermal stability of the zinc complexes has been investigated by simultaneous TG/DTG-DTA technique. The ability of the complexes to bind to calf-thymus DNA (CT DNA) has been studied by UV-absorption and fluorescence emission spectroscopy as well as viscosity measurements. UV studies of the interaction of the complexes with DNA have shown that they can bind to CT DNA and the corresponding binding constants to DNA have been calculated and evaluated. The complexes most probably bind to CT DNA via intercalation as concluded by studying the viscosity of a DNA solution in the presence of the complexes. Competitive studies with ethidium bromide (EB) have shown that the reported complexes can displace the DNA-bound EB, suggesting strong competition with EB for the intercalation site.

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 499-40-1 is helpful to your research., Application of 499-40-1

Variance in coordination numbers, nuclearities and architectures with metal ion templates

A mononuclear compound [Cd(dpaH)2(dca)2] (1) and a tetranuclear based 2D coordination polymer [Hg4(dpa) 4(dca)4]n (2) [dpaH = 2,2?- dipyridylamine, dpa = anion of dpaH, dca = dicyanamide] have been synthesized and characterized. X-ray structural analyses reveal that cadmium(II) center in 1 has a distorted octahedral geometry with a CdN6 chromophore ligated through two bidentate neutral dpaH units along with two nitrile N atoms of two terminally bound dca units in mutual cis orientation. Each of the four independent mercury(II) centers in 2 adopts a distorted trigonal bipyramidal environment coordinated by two pyridine N atoms of two different anionic dpa ligands, two nitrile N atoms of two mu1,5 bridged dca units and the fifth position is occupied by the amide N of one dpa.

Ruthenium(II) p-cymene complex bearing 2,2?-dipyridylamine targets caspase 3 deficient MCF-7 breast cancer cells without disruption of antitumor immune response

[Ru(eta6-p-cym)Cl{dpa(CH2)4COOEt}][PF6] (cym = cymene; dpa = 2,2?-dipyridylamine; complex 2) was prepared and characterized by elemental analysis, IR and multinuclear NMR spectroscopy, as well as ESI-MS and X-ray structural analysis. The structural analog without a side chain [Ru(eta6-p-cym)Cl(dpa)][PF6] (1) as well as 2 were investigated in vitro against 518A2, SW480, 8505C, A253 and MCF-7 cell lines. Complex 1 is active against all investigated tumor cell lines while the activity of compound 2 is limited only to caspase 3 deficient MCF-7 breast cancer cells, however, both are less active than cisplatin. As CD4+ Th cells are necessary to trigger all the immune effector mechanisms required to eliminate tumor cells, besides testing the in vitro antitumor activity of 1 and 2, the effect of ruthenium(II) complexes on the cells of the adaptive immune system have also been evaluated. Importantly, complex 1 applied in concentrations which were effective against tumor cells did not affect immune cell viability, nor did exert a general immunosuppressive effect on cytokine production. Thus, beneficial characteristics of 1 might contribute to the overall therapeutic properties of the complex.

Phyllanthoside-Phyllanthostatin Synthetic Studies. 8. Total Synthesis of (+)-Phyllanthoside. Development of the Mitsunobu Glycosyl Ester Protocol

The first total syntheses of the antineoplastic glycoside (+)-phyllanthoside (1) and the parent disaccharide (-)-phyllanthose (5) have been achieved. Stereoselective Koenigs-Knorr coupling of two 6-deoxyglucose derivatives, bromide 54 and alcohol 55, generated the uncommon 1? ? 2beta glycosidic linkage of (-)-phyllanthose. A stereochemically convergent Mitsunobu reaction of protected disaccharide 87 with aglycon carboxylic acid 80, prepared via asymmetric synthesis, then led to 1 of high enantiomeric purity. The Mitsunobu procedure comprises an efficient general method for stereospecific assembly of beta-glycosyl esters.
