Dinuclear copper(II) phosphonates containing chelating nitrogen ligands: Synthesis, structure, magnetism and nuclease activity

The reaction of Cu(ClO4)2¡¤6H2O with RPO 3H2 (R = cyclopen-tyl, isopropyl, trichloromethyl) in the presence of chelating nitrogen ligands bpya or bpy afforded dinuclear copper phosphonates. [Cu2 (mu2-C5H 9PO3) 2 (bpya) 2 (H2O) 2] (H2O) 4 (1) [Cu2 (mu2-C3H7PO3) 2 (bpya) 2 (H2O) 2] (H2O) 2 (2) and [Cu2 (mu2-CCl3PO3) 2 (bpy) 2 (MeOH) 2] (H2O) (3) [bpya = 2, 2′-bipyridyl-amine, bpy = 2, 2′-bipyridine]. The molecular structures of these complexes reveal that they are isostructural and possess two copper centres that are bridged to each other by two isobidentate phosphonate ligands generating an eight-membered Cu2O2P2 ring. Magnetic studies on 2 reveal anti-ferromagnetic behaviour at low temperatures. Dinuclear complexes 1-3 were found to be excellent nucleases and can convert supercoiled pBR322 DNA form I into nick form II in only 30 min without the need for any external oxidant through a hydrolytic pathway.

A bio-relevant supramolecular Co(ii)-complex for selective fluorescence sensing of muM range inorganic As(iii) in aqueous medium and its intracellular tracking in bacterial systems

A novel Co(ii)-complex {i.e. [Co(n-BuM)(DPA)(H2O)2]¡¤H2O} [n-BuMH2 = n-butylmalonic acid and DPA = 2,2?-dipyridylamine] was synthesized. The supramolecular feature, i.e. a metal coordinated and free guest water mediated hydrogen-bonding interaction assisted supramolecular pipi assembly, has been observed in the crystal structure of the Co(ii)-complex in the solid state. The role of different water molecules (metal coordinated and free guest water molecules) had also been scrutinized via theoretical studies. The fluorescent nature of the aqueous solution of the Co(ii)-complex has been utilized for selective muM range toxic inorganic As(iii)-sensing in aqueous medium. The Co(ii)-probe is very specific towards toxic As(OH)3 even in the presence of several ions and other arsenic sources like inorganic As(v)-oxoanions and organic arsenic species like cacodylic acid. The bio-relevant nature of the fluorescent probe of the Co(ii)-complex has also been examined. The luminous Co(ii)-probe has been employed for the intracellular tracking of As(iii) in bacterial systems including As(iii)-resistant bacteria Bacillus aryabhattai and As(iii) non-resistant bacteria Bacillus subtilis.

Novel anthracycline-spacer-beta-glucuronide, -beta-glucoside, and -beta-galactoside prodrugs for application in selective chemotherapy

A series of anthracycline prodrugs containing an immolative spacer was synthesized for application in selective chemotherapy. The prodrugs having the general structure anthracycline-spacer-beta-glycoside were designed to be activated by beta-glucuronidase or beta-galactosidase. Prodrugs with -chloro, -bromo or -n-hexyl substituents on the spacer were synthesized as well as prodrugs containing a -beta-glucuronyl, -beta-glucosyl or -beta-galactosyl carbamate specifier. The key step in the synthesis of all prodrugs is the highly beta-diastereoselective addition reaction of the anomeric hydroxyl of a glycosyl donor to a spacer isocyanate resulting in the respective beta-glycosyl carbamate pro-moieties. The resulting protected pro-moieties were coupled to an anthracycline. Prodrugs were evaluated with respect to activation rate by the appropriate enzyme and additionally, their IC50 values were determined. Optimal prodrugs in this study were at least 100- to 200-fold less toxic than their corresponding drug in vitro and were activated to the parent drug in a half-life time of approximately 2h.

Glycosyl Phosphites as Glycosylation Reagents: Scope and Mechanism

The glycosylation reactions with glycosyl phosphites in the presence of catalytic amounts of TMSOTf at low temperature have been studied with different donors and acceptors for the synthesis of several glycosides, including O-glycosides, S-glycosides, C-glycosides, and glycopeptides.Mechanistic investigations of the reactions indicate that the glycosyl phosphite is activated by either TfOH or TMSOTf, depending on how the substrates are mixed.When the acceptor is treated with TMSOTf first, the glycosyl phosphite is activated by the resulting TfOH.The glycosyl phosphite can also be activated by TMSOTf directly.The best result is, however, to mix the acceptor and TMSOTf first, followed by addition of the glycosyl phosphite.

Ni(II) complexes with 2,2-dipyridylamine and salicylaldehydes: Synthesis, crystal structure and interaction with calf-thymus DNA and albumins

The synthesis of four cationic mixed?ligand Ni(II) complexes with 2,2??dipyridylamine (dpamH) and substituted salicylaldehydes (X?saloH) was undertaken in an effort to discover new biologically active compounds. The complexes with the general formula [Ni(dpamH)2(X?salo)]Cl, 3?6, namely [Ni(dpamH)2(5?Cl?salo)]Cl, 3, [Ni(dpamH)2(5?Br?salo)]Cl, 4, [Ni(dpamH)2(5?CH3?salo)]Cl, 5, and [Ni(dpamH)2(3?OCH3?salo)]Cl¡¤CH3OH, 6, were characterized by elemental analyses, FT?IR and UV?vis spectroscopy, magnetic and conductivity measurements. In addition, two analogous nickel?salicylaldehydato complexes in the absence of dpamH were prepared and characterized as [Ni(5?Cl?salo)2(CH3OH)2], 1 and [Ni(5?Br?salo)2(CH3OH)2], 2. The structures of complexes 1?6 were determined by X?ray crystallography revealing octahedral coordination of nickel (II) and monomeric nature of the compounds. Spectroscopic (UV?vis), electrochemical (cyclic voltammetry) and physicochemical (viscosity measurements) techniques were employed in order to study the binding mode and strength of the complexes to calf?thymus (CT) DNA, while competitive studies with ethidium bromide (EB), performed by fluorescence spectroscopy, revealed the ability of the complexes to displace the DNA-bound EB. The complexes bind to DNA probably via intercalation exhibiting high DNA?binding constants. For the cationic complexes 3?6, the coexistence of an electrostatic interaction with CT DNA may be also suggested. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the determined binding constants exhibit relative high values.

Diarylamino functionalized pyrene derivatives for use in blue OLEDs and complex formation

Three new 2,2?-dipyridylamino functionalized pyrene derivatives, 1-pyrenyl-2,2?-dipyridylamine (1), 4-(1-pyrenyl)phenyl-2,2?- dipyridylamine (2), and 4-[4?-(1-pyrenyl)biphenyl]-2,2?- dipyridylamine (3) have been synthesized and fully characterized. For comparison of electronic properties, a diphenylamino functionalized molecule 4-[4?-(1-pyrenyl)biphenyl]diphenylamine (4) has also been synthesized. Compounds 1-4 are bright blue emitters in solution and in the solid state with lambdamax at ?420-460 nm and a high emission efficiency in solution. All four compounds form amorphous glasses with Tg values of 66 C, 79 C, 165 C, and 98 C, respectively. The electronic properties of the four compounds were examined by spectroscopic methods, cyclic voltammetry and Gaussian 98 molecular orbital calculations. The utilities of this class of molecules in OLEDs have been demonstrated by EL devices of compounds 3 and 4, which showed that 3 can function as a bright blue emitter and an electron transport material in a double-layer device while 4 can function as a bright blue emitter and a hole transport molecule in a triple-layer device. The dipyridylamino functional group in molecules 1-3 are capable of chelating to metal ions such as Zn(II) as demonstrated by the synthesis and structure of the complex [2-(Zn(O2CCF3) 2]2 (5). The binding of Zn(II) ions to the dipyridyl group causes a reduction of the emission efficiency of the ligand 2.
