Polynuclear Complexes of Ligands Containing in Situ Formed Oxazinane and Oxazolidine Rings with Appended Alkoxyl and Phenol Groups

In situ formation of ligands is an efficient approach to synthesizing novel complexes with unique coordinating moieties. Oxazolidines and oxazinanes are 1,3-N,O-containing five-membered and six-membered heterocycles, respectively. Metal complexes of Ligands derived from these two heterocycles are rather rare. In this work, we designed and synthesized a novel multihydoxy ligand, 2((2,3-dihydroxypropylamino)methyl)phenol (H3L1). It contains both aminoethanol and aminopropanol units, which may be employed to react with aldehydes to afford oxazolidines and oxazinanes, respectively. Thus, H3L1 was reacted with metal salts in the absence cr presence of aldehydes to afford complexes [Cu(HL1)](2) (1), [CuL2](4)center dot 4CH(3)OH (2) [Zn5Na2(L-3)(4)(DMSO)(2.65)(DMF)(1.35)]-DMF (3), and [Ni(HL4)](2) (4). Complex 1 is a dialkoxo-bridged binuclear Cu(II) complex. The coordination moieties are linked by intermolecular C-H center dot center dot center dot O hydrogen bonds to afford a 1D double-chain supramolecular structure. Interestingly, in complexes 2-4, H3L1 has been reacted with formaldehyde, salicylaldehyde, and 2,6-diformyl-4-cresol to afford novel ligands H2L2, H3L3, and H3L4, respectively. The combination of in situ formed oxazinane or oxazolidine rings with appended alkoxyl and phenol functionalities in these ligands has been demonstrated to form a rich diversity of coordination structures. Thus, 2 is a tetranuclear Cu(II) complex with a face-sharing double defective cubane core structure. In this complex, (L-2)(2-) ligands coordinate in two different bridging modes with the Harris notations of 3.1(1)2(12)2(13)1(1) and 3.1(1)3(123)1(1)1(1), respectively. Complex 3 has an interesting heptanuclear Zn5Na2 core structure. A central Zn(II) is coordinated with four alkoxo O atoms from four (L-3)(3-) ligands. Each of the O atom further bridges another Zn(II) atom, resulting in a Zn-5 moiety, which is then connected to two Na+ by phenoxo O bridges, finally affording the Zn5Na2 core. The bridging mode of (L-3)(3-) can be designated as 4.2(12)2(13)1(1)3(124)1(1). And Complex 4 is a binuclear Ni(II) complex containing di-mu(2)-phenoxo bridges. The coordination moieties are linked by intermolecular C-H center dot center dot center dot pi, C-H center dot center dot center dot O, and pi center dot center dot center dot pi interactions to afford a two-dimensional supramolecular network. These results indicate that the combination of in situ formed oxazinane and oxazolidine rings with appended phenol and alkoxyl functionalities is an efficient approach to developing novel ligands and complexes with a rich structural diversity. Variable temperature magnetic data measurements revealed that medium antiferromagnetic interaction exists between the Cu(II) centers in complex 1 with a -2J value of 278 cm(-1). And in complex 4, weak antiferromagnetic coupling occurs between the Ni(II) centers, with a -2J value of 9.36 cm(-1).

Lanthanide Complexes with a Tripodal Nitroxyl Radical Showing Strong Magnetic Coupling

A series of isomorphous mononuclear complexes of Ln(III) ions comprising one stable tripodal oxazolidine nitroxyl radical were obtained in acetonitrile media starting from nitrates. The compounds, [LnRad(NO3)(3)] (Ln = Gd, Tb, Dy, Tm, Y; Rad = 4,4-dimethyl-2,2-bis(pyridin-2-yl)-1,3-oxazolidine-3-oxyl), have a molecular structure. Their coordination polyhedron, LnO(7)N(2), can be described as a tricapped trigonal prism with symmetry not far from D-3h. The extracted value of 23 cm(-1) for the antiferromagnetic coupling of Gd-Rad established from the DC magnetic and EPR data is a record strength for the complexes of 4f elements with nitroxyl radicals. The terbium derivative displays frequency-dependent out-of-phase signals in zero field, indicating single-molecule magnetic behavior. With an applied field of 0.1 T, an effective barrier of 57 cm(-1) is found.

Depletion of M. tuberculosis GlmU from Infected Murine Lungs Effects the Clearance of the Pathogen

M. tuberculosis N-acetyl-glucosamine-1-phosphate uridyltransferase (GlmU(Mtb)) is a bifunctional enzyme engaged in the synthesis of two metabolic intermediates N-acetylglucosamine-1-phosphate (GlcNAc-1-P) and UDP-GlcNAc, catalyzed by the C- and N-terminal domains respectively. UDP-GlcNAc is a key metabolite essential for the synthesis of peptidoglycan, disaccharide linker, arabinogalactan and mycothiols. While glmU(Mtb) was predicted to be an essential gene, till date the role of GlmU(Mtb) in modulating the in vitro growth of Mtb or its role in survival of pathogen ex vivo / in vivo have not been deciphered. Here we present the results of a comprehensive study dissecting the role of GlmU(Mtb) in arbitrating the survival of the pathogen both in vitro and in vivo. We find that absence of GlmU(Mtb) leads to extensive perturbation of bacterial morphology and substantial reduction in cell wall thickness under normoxic as well as hypoxic conditions. Complementation studies show that the acetyl-and uridyl-transferase activities of GlmU(Mtb) are independently essential for bacterial survival in vitro, and GlmU(Mtb) is also found to be essential for mycobacterial survival in THP-1 cells as well as in guinea pigs. Depletion of GlmU(Mtb) from infected murine lungs, four weeks post infection, led to significant reduction in the bacillary load. The administration of Oxa33, a novel oxazolidine derivative that specifically inhibits GlmU(Mtb), to infected mice resulted in significant decrease in the bacillary load. Thus our study establishes GlmU(Mtb) as a strong candidate for intervention measures against established tuberculosis infections.

Theoretical Perspectives on Redox Non-Innocent Oxazolidine N-Oxide Iron Nitroxide Complexes

One-electron redox processes in ligands that exhibit non-innocent behaviour invariably leads to the generation of radical species, which, when coupled with redox-active metal centres, can lead to strong magnetic exchange, ambiguous electronic structures and even spin crossover (SCO). We have chosen two iron complexes [Fe-II(L-center dot)(2)](BF4)(2) (1) and [Fe-III(L-)(2)](BPh4) (2) [with L-center dot = 4-dimethyl-2,2-di(2-pyridyl)oxazolidine N-oxide] as the basis for an extensive theoretical study to determine the influence and interplay of the strong magnetic exchange, the redox non-innocent behaviour and any possible spin transitions. A series of calculations established the low-spin character of the Fe in both the complexes and gave us valuable insight into the electronic structure of 1 and 2 along with their one- and two-electron reduced species. An attempt has been made to relate the bonding features to the energy difference between different spin states and to the influence of the exchange coupling on any possible SCO properties.

1,3-Dipolar Cycloaddition-Decarboxylation Reactions of an Azomethine Ylide with Isatoic Anhydrides: Formation of Novel Benzodiazepinones

A nonstabilized azomethine ylide reacts with a wide range of substituted isatoic anhydrides to afford novel 1,3-benzodiazepin-5-one derivatives, which are generally isolated In high yield. The transformations involve 1,3-dipolar cycloaddition reactions of the ylide with the anhydrides to give transient, and in a representative case spectroscopically observable, oxazolidine Intermediates that undergo ring-opening-decarboxylation-ring-closing reaction cascades to yield the 1,3-benzodiazepin-5-one products.

Bromoacetylfluorescein monoaldehyde as a fluorescence turn-on probe for cysteine over homocysteine and glutathione

A novel fluorescent probe possessing the two different functional groups of bromoacetyl ester and aldehyde functionality was designed as a selective chemodosimeter for cysteine (Cys). The initially nonfluorescent bromoacetyl-fluorescein monoaldehyde (3) was rapidly transformed into a strongly fluorescent molecule through the first nucleophilic substitution followed by the subsequent ester bond cleavage reactions by one Cys and the second oxazolidine formation reaction with another Cys. The molecular probe exhibited a rapid response toward Cys over homocysteine or glutathione owing to the favorable kinetic processes with Cys, of which property was successfully applied for live cell imaging with tunicamycin, an inducer of cytosolic Cys.

Formation of Heterocyclic and Polycyclic Compounds from Amino Alcohols and Dialdehydes

Amino alcohols typically react with aldehydes to produce oxazolidines. It was hypothesized that the condensation of several commercially available amino alcohols with dialdehydes would produce a series of bicyclic oxazolidines containing two secondary amines. However, there were remarkable differences in the type of products formed depending on the structure of the dicarbonyl compounds and the reaction conditions. When linear aliphatic dialdehydes such as glyoxal were used, the expected bis-oxazolidines were not produced; instead, polycyclic structures or oxazines were formed. However, when cyclic dialdehydes such as 1,3/1,4 cyclohexane dicarboxaldehyde were used, they resulted in products bearing the desired oxazolidine moieties.

Effect of Tanning Agents on Collagen Structure and Response to Strain in Leather

A variety of tanning agents are used to produce leather of different mechanical performances and properties. How different tanning agents affect the structure of leather, and consequently the mechanism underlying the performance of the differently tanned leathers, is not well understood. We used small-angle X-ray scattering to investigate the structure of ovine leather tanned with chromium, zirconium, mimosa, oxazolidine or tetrakis hydroxymethyl phosphonium sulfate (THPS), or selected pairs of these agents. Leather tanned using THPS and THPS in combination with mimosa retained the most oriented collagen fibril structure. Treatment with chromium, zirconium or zirconium and mimosa resulted in the least oriented fibril structures. The effect of oxazolidine with mimosa was intermediate between these. A high natural collagen fibril orientation in a skin is normally associated with high strength while a high degree of crosslinking normally results in a lower fibril orientation. We suggest that the extent of crosslinking in the samples is reflected in their fibril orientation, with more crosslinking producing stronger leathers. This interpretation is supported by the differences in shrinkage temperatures: those leathers for which orientation index (a measure of collagen fibril alignment) changed most had a lower shrinkage temperature (which is normally interpreted as more tanning). This provides a greater understanding of the mechanism of action of tanning agents in the development of the properties of leather.
