The gadolinium(III) chelates Gd(dtpaH2), Gd(hfac)3, Gd(tta)3 and Gd(qu)3 with dtpa1⁄4 1,1,4,7,7-diethylenetriaminepentaacetate, hfac1⁄4 hexafluoroacetylacetonate, tta1⁄4 thenoyltrifluoroacetonate and qu1⁄4 8-quinolinolate (or oxinate) show a phosphorescence under ambient conditions. While the UV emission of Gd(dtpaH2) at kmax 1⁄4 312 nm comes from a metal-centered ff state, the bluish (kmax 1⁄4...
background: the incorporation of thallium-201 into 8-hydroxyquinoline was targeted for cell labeling due to interesting physical properties and wide availability of this nuclide as a single photon emission computed tomography (spect) radionuclide. materials and methods: thallium-201 (t1/2=3.04 d) in tl+ form was converted to tl3+ cation in presence of o3/6m hcl and di-isopropyl ether, controlle...
DNA interactions of monofunctional organometallic osmium(II) antitumor complexes in cell-free media.
This work is the first in-depth study of osmium binding to DNA and confirms the pharmacological activity of a new class of anticancer metallodrugs. We investigated the interactions between the potential biological target DNA and four osmium(II) arene complexes, of the type [(eta 6-arene)Os(LL)Cl]n+, where arene = biphenyl or p-cymene and LL = ethylenediamine, picolinate, or oxinate in an effort...
