A potential anticancer agent: 5-chloro-7-iodo-8-hydroxyquinolinium dichlorido(5-chloro-7-iodoquinolin-8-olato-κ2 N,O)palladium(II) dihydrate
The title Pd(II) coordination compound, (C(9)H(6)ClINO)[PdCl(2)(C(9)H(4)ClINO)]·2H(2)O, was prepared as a potential anti-cancer agent. Its structure is ionic and consists of a square-planar [PdCl(2)(CQ)](-) complex anion (CQ is 5-chloro-7-iodo-quinolin-8-olate), with the Pd(II) atom surrounded by two chloride ligands in a cis configuration and one N,O-bidentate CQ mol-ecule, a protonated anion ...
متن کاملSpectrophotometric Determination of Tantalum(V) with 5-Iodo-8- -hydroxyquinoline-7-sulphonic Acid
Tantalum(V) reacts with 5-iodo-8-hydroxyquinoline-7-sulphonic acid to form a yellowish coloured complex having maximum absorbance at 405 nm in citric acid medium. The relatively slow reaction at room temperature is completed in 10 minutes at 40 °c. The colour is stable for at least 12 hr. Effects of heating temperature, time, pH, reagent concentration and other variables have been studied. The ...
متن کامل5-Chloro-8-hydroxyquinolinium nitrate
The 5-chloro-8-hydroxy-quinolinium cation in the the title ion pair, C(9)H(7)ClNO(+)·NO(3) (-), is approximately coplanar with the nitrate anion [dihedral angle = 16.1 (1)°]. Two ion pairs are hydrogen bonded (2 × O-H⋯O and 2 × N-H⋯O) about a center of inversion, generating an R(4) (4)(14) ring.
متن کاملThe polarographic determination of thyroxine and 3:5-diiodotyrosine.
Although biological methods are used for assessing the value of thyro-active materials, chemical methods are also available to determine the thyroxine content of such substances. These methods are mainly based on the estimation of iodine as 'thyroxine iodine' (Harington & Randall, 1929; Leland & Foster, 1932; Brand & Kassell, 1939). Polarographic analysis suggests itself as a means of simplifyi...
متن کاملAntifungal activity of 5-, 7-, and 5,7-substituted 2-methyl-8-quinolinols.
2-Methyl-8-quinolinol and sixteen 5-, 7-, and 5,7-substituted derivatives with fluoro, chloro, bromo, iodo, nitro, and amino substituents were tested for in vitro antifungal activity against five fungi, Aspergillus niger, A. oryzae, Trichoderma viride, Myrothecium verrucaria, and Trichophyton mentagrophytes. The 5,7-dichloro and 5,7-dibromo derivatives were the most fungitoxic of the compounds ...
