The reaction of the redox-active ligand, Hpyramol (4-methyl-2-N-(2-pyridylmethyl)aminophenol) with K(2)PtCl(4) yields monofunctional square-planar [Pt(pyrimol)Cl], PtL-Cl, which was structurally characterised by single-crystal X-ray diffraction and NMR spectroscopy. This compound unexpectedly cleaves supercoiled double-stranded DNA stoichiometrically and oxidatively, in a non-specific manner
The binding capability of three ruthenium polypyridyl compounds of structural formula [Ru(apy)(tpy)Ln-](ClO4)(2-n) [1a-c; apy = 2,2'-azobis(pyridine), tpy = 2,2':6',2''-terpyridine, L = Cl, H2O, CH3CN] to a fragment of DNA was studied. The interaction between each of these complexes and the

The dinuclear platinum complexes with aliphatic diamines [{cis-Pt(NH(3))(2)Cl}(2)(mu-H(2)N(CH(2))(6)NH(2))](NO(3))(2) (1,1/c,c) and [{trans-Pt(NH(3))(2)Cl}(2)(mu-H(2)N(CH(2))(4)NH(2))](NO(3))(2) (1,1/t,t), which are known to be highly active in vitro against several cancer cell lines, have been modified with a fluorogenic reporter (carboxyfluorescein diacetate, CFDA) and a hapten (dinitrophenyl
The novel steroidal conjugate 17-α-[2-phenylpyridyl-4-ethynyl]-19-nortestosterone (LEV-ppy) (1) and the steroid-C,N-chelate ruthenium(II) conjugate [Ru(η(6)-p-cymene)(LEV-ppy)Cl] (2) have been prepared. At 48 h incubation time, complex 2 is more active than cisplatin (about 8-fold) in T47D (breast cancer) and also shows an improved

Potential biological and medical applications of organometallic complexes are hampered by a lack of knowledge of their aqueous solution chemistry. We show that the hydrolytic and aqueous solution chemistry of half-sandwich OsII arene complexes of the type [(eta6-arene)Os(XY)Cl] can be
