METAL ORGANIC FRAMEWORKS AS CATALYSTS AND HYDROCARBON OXIDATION METHODS THEREOF
A metal organic framework comprising zinc (II) ions and second metal ions, such as iron (II) ions, cobalt (II) ions, and copper (II) ions as nodes or clusters and coordinated 1,3,5-benzenetricarboxylic acid struts or linkers between them forming a porous coordination network in the form of polyhedral crystals that are isostructural to HKUST-1. Transmetallation processes for producing the metal organic frameworks, as well as methods for applications of the metal organic frameworks as catalysts, specifically catalysts for the oxidation of cyclic hydrocarbons, such as toluene, cyclohexane, and methylcyclohexane.
Compounds for use as iron(III) MRI contrast agents
Provided are macrocyclic compounds and compounds with two or more macrocyclic groups, iron coordinated macrocyclic compounds, and iron coordinated compounds with two or more macrocyclic groups. The iron is high-spin iron(III). The iron coordinated compounds may exhibit a negative redox potential (e.g., relative to a normal hydrogen electrode at a biologically relevant pH, for example, a pH of 6.5-7.5). The compounds can be used as MRI contrast agents.
Derivatization of carbon
Chemical modification of the surface of elemental carbon comprises a first stage of attaching a compound with an azo group to the elemental carbon and then a second stage of decomposing the azo group in the presence of one or more compounds with an olefinic group so that decomposition of the azo group forms radicals attached to the carbon surface and a said radical forms a covalent bond to a said olefinic group. The second stage may proceed as a polymerization of a vinyl monomer with a redox active group such as ferrocene, anthracene or anthraquinone. The resulting polymer-modified carbon may be used in an electrochemical sensor.

COMBINATION OF HER2/NEU ANTIBODY WITH HEME FOR TREATING CANCER
The present invention relates to a method of treating HER2/NEU overexpressing cancers. The inventors discovered that the heme-mediated formation of dimers and in general oligomers of Trastuzumab is associated with an improved complement-mediated cytotoxicity on breast cancer cells. The present data highlight that the sensitivity to heme of Trastuzumab, may have major repercussion on its therapeutic activity. Thus the invention relates to the combination of an HER2/neu antibody with a heme and/or of its oligomers and its therapeutic composition in the HER2/NEU characteristic cancer treatment.

ANTI-CANCER AGENT AND CANCER CELL KILLING METHOD
[Object] An anticancer agent capable of continuously killing cancer cells in a plurality of phases is provided.
[Solution] An anticancer agent contains a complex produced by making a metal-salen complex compound, which includes a central metal and (N, N, O, O) as a quadridentate ligand and is magnetic, bind to taxane molecules which are anticancerous; and the anticancer agent is to kill cancer cells regarding which phase transition of its cell cycle occurs between phases including Gap1, Synthesis, Gap2, and Mitosis and Cytokinesis. The present disclosure is suited for use to kill cancer cells of breast cancer and, particularly, cancer cells of triple-negative breast cancer. The present disclosure is designed to make the anticancer agent contact the cancer cells in two or more continuous phases selected from a group consisting of Gap1, Synthesis, Gap2, and Mitosis and Cytokinesis and kill the cancer cells.
