An in vivo highly antitumor-active tetrazolato-bridged dinuclear platinum(II) complex largely circumvents in vitro cisplatin resistance: two linkage isomers yield the same product upon reaction with 9-ethylguanine but exhibit different cytotoxic profiles.
Cytotoxicity assays of azolato-bridged dinuclear Pt(II) complexes, [{cis-Pt(NH(3))(2)}(2)(μ-OH)(μ-azolato)](2+), where the azolato was pyrazolato (1), 1,2,3-triazolato-N1,N2 (2), tetrazolato-N1,N2 (3), or tetrazolato-N2,N3 (4), were performed in cisplatin-sensitive and -resistant human non-small-cell lung cancer cell lines (PC-9 and PC-14). These complexes largely circumvented the cisplatin res...

The Dinuclear Cu (II) complex [{CuCl}2(μ – tppz)](PF6)2, where tppz represents tetra-2-pyridinylpyrazine, has been prepared and characterized by elemental analysis, 1H-NMR, IR and UV-vis spectroscopies. A crystal structure of the complex showed the Cu (II) are surrounded by three N atoms of tppz bridging ligand and one Cl atom. Crystal structure data are as follows: crystal system monoclinic, s...
متن کاملHighly efficient uptake into cisplatin-resistant cells and the isomerization upon coordinative DNA binding of anticancer tetrazolato-bridged dinuclear platinum(II) complexes.
We examined the cytotoxicity and cellular uptake in L1210 murine leukemia cells, as well as the coordinative reaction with the guanine derivative 9-ethylguanine (9EtG), of a series of μ-hydroxo-μ-tetrazolato dinuclear platinum(II) complexes (tetrazolato-bridged complexes), [{cis-Pt(NH3)2}2(μ-OH)(μ-tetrazolato-N1,N2)](2+) (5-H-X) and [{cis-Pt(NH3)2}2(μ-OH)(μ-5-R-tetrazolato-N2,N3)](n+), where R ...

Copper complexes of [Cu(phen)(tda)].2H2O(1) and [(phen)2Cu(µ-tda) Cu(phen)](ClO4)2.1.5H2O (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. Both complexes were characterized by elemental analysis, IR, UV–Vis spectroscopy and cyclic voltammetry. Their solid state struct...
متن کاملCucurbit[10]uril binding of dinuclear platinum(II) and ruthenium(II) complexes: association/dissociation rates from seconds to hours.
A simpler method for the purification of cucurbit[10]uril (Q[10]) from the Q[10].Q[5] inclusion complex is reported. 1,12-Diaminododecane was used to displace Q[5], as opposed to the synthetic melamine derivative currently used. The binding of trans-[{PtCl(NH(3))(2)}(2)(micro-NH(2)(CH(2))(8)NH(2))](2+) (CT008) and [{Ru(phen)(2)}(2)(micro-bb(5))](4+) {phen = 1,10-phenanthroline; bb(5) = 1,5-bis[...
