  • Patent number: 10118893
    Abstract: The development of anticancer metal-based drugs was done by reacting oyelamine with selenous acid to produce a quaternary ammonium salt which consequently converted to platinum and cobalt cationic complexes via complexing the first compounds with platinum (II) or cobalt (II) ions. The surface properties studies that were conducted included critical micelle concentration (CMC), maximum surface excess (?max) and minimum surface area (Amin). Free energy of micellization (?G° mic) and adsorption (?G° ads) were calculated. Antitumor activities were tested by using Ehrlich Acites Carcinoma (EAC) as a model system of mice cell tumor. These compounds were also tested in vitro on human five monolayer tumor cell lines: MCF7 (Breast carcinoma), HEPG2 (liver carcinoma), and HCT116 (colon carcinoma), etc. FTIR spectra, elemental analysis and H1 NMR spectrum were performed to insure the purity of the prepared compounds.
