Reactions of the complexes bisethylendiammine gold(III) and bisethylendiammine platinum(II) with calfthymus DNA were comparatively analysed. Both complexes bind DNA non-covalently most probably on the basis of electrostatic interactions. Binding of either complex at low ratios results into modest modifications of B-type DNA conformations, as detected by CD. Far larger CD alterations are observe...

In the title compound, (C(21)H(22)N)(2)[AuCl(4)]Cl, the Au(III) atom adopts a square-planar coordination geometry defined by four chloride ions. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the organic cations and the uncoordinated chloride ion.

The Ir(III) compound Tp(Ms'')Ir(N2), that contains a pentadentate, doubly metalated 3-mesityl substituted tris(pyrazolyl)borate ligand, induces the cleavage of C-H and C-Cl bonds of CH2Cl2 to yield a highly electrophilic chlorocarbene Ir=C(H)Cl complex.

In the neutral mononuclear iridium(III) title complex, [Ir(C(15)H(10)N)(2)Cl(C(5)H(5)N)]·H(2)O, the Ir atom is coordinated by two N atoms and two C atoms from two 2-(quinolin-2-yl)-phenyl ligands, one N atom from a pyridine ligand and one Cl atom in an octa-hedral geometry.

The centrosymmetric title cluster, hexa-aquadi-μ(3)-carbonato-hexa-cyclamhexa-μ(2)-hydroxido-dodeca-μ(2)-oxido-hexa-mang-an-ese(IV)hexa-manganese(III) octa-chloride tetra-cosa-hydrate, [Mn(12)(CO(3))(2)O(12)(OH)(6)(C(10)H(24)N(4))(6)(H(2)O)(6)]Cl(8)·24H(2)O, has two μ(3)-CO(3) groups that not only bridge octahedrally coordinated Mn(III) ions but also act as acceptors to two different kinds of h...

BACKGROUND In the present study, we examined breast (bca) and colorectal cancer (crc) incidence and mortality and stage at diagnosis for First Nations (fn) individuals and all other Manitobans (aoms). METHODS Several population-based databases were linked to determine ethnicity and to calculate age-standardized incidence and mortality rates. Logistic regression was used to compare bca and crc...

Two ruthenium(III) complexes, namely trans-indazolium[tetrachlorobis(indazole)- ruthenate(III)], HInd[RuInd(2)Cl(4)] and trans-imidazolium[tetrachlorobis(imidazole)- ruthenate(III)], HIm[RuIm(2)Cl(4)] exhibit high anticancer activity in an autochthonous colorectal carcinoma model in rats. Recently, it has been shown that both complexes bind specifically to human serum apotransferrin and the res...

By controlled Anderson type rearrangement reactions complexes of the general formula trans-[Os(IV)Cl(4)(Hazole)(2)], where Hazole = 1H-pyrazole, 2H-indazole, 1H-imidazole, and 1H-benzimidazole, have been synthesized. Note that 2H-indazole tautomer stabilization in trans-[Os(IV)Cl(4)(2H-indazole)(2)] is unprecedented in coordination chemistry of indazole. The metal ion in these compounds possess...

AIMS To determine the effects of anaerobic electron acceptors on 3-methylindole (3-MI) and 4-methylphenol (4-MP) production in swine lagoon enrichments and Clostridium scatologenes ATCC 25775. METHODS AND RESULTS Swine lagoon sediment was incubated anaerobically in tryptone-yeast extract medium with (10 mmol l(-1)) Na(2)SO(4), KNO(3), dimethyl sulfoxide or Fe(III). With Fe(III), 3-MI and 4-MP...

The crystal structure of the title compound, {[AsCl3(C5H5N)]·H2O} n , is characterized by polymeric chains consisting of alternating arsenic and chlorine atoms running parallel to the a axis. O-H⋯Cl and N-H⋯O hydrogen bonds mediated by non-coordinating water mol-ecules assemble these chains into a three-dimensional framework. The As(III) atom, the atoms of the pyridinium ring and the water O at...
