  • Patent number: 9562062
    Abstract: The present invention relates to a ligand compound, a catalyst system for ethylene oligomerization, and a method for ethylene oligomerization using the same. The catalyst system for ethylene oligomerization according to the present invention not only has excellent catalytic activity but also shows more improved liquid olefin selectivity, and enables more effective preparation of an alpha-olefin through the oligomerization of ethylene because it is particularly possible to control the selectivity to 1-hexene or 1-octene.

  • Patent number: 9012669
    Abstract: An efficient process for synthesizing phosphaplatins in large quantities is disclosed by adding platinum complex to a concentrated pyrophosphate solution at pH from between about 6.0 to 8.5. After stirring, the temperature and pH are lowered to precipitate out desired phosphaplatins. Particularly, the disclosed processes reduce the need to use large volumes of starting materials, and shorten the reaction time. In addition, disclosed is a process for recycling un-reacted materials from a first phosphaplatins synthesis.

  • Patent number: 8653132
    Abstract: The present invention provides pharmaceutical compositions comprising phosphaplatins, stable isolated monomeric phosphato complexes of platinum (II) and (IV). In some embodiments, such compositions may be useful for treating cancers, including cisplatin- and carboplatin-resistant cancers. The provided phosphaplatin complexes do not readily undergo hydrolysis and are quite soluble and stable in aqueous solutions. Moreover, these complexes—unlike cisplatin, carboplatin, and related platinum-based agents—do not bind DNA. Rather, data suggests that phosphaplatins trigger overexpression of fas and fas-related transcription factors and some proapoptotic genes such as Bak and Bax. Nevertheless, the complexes exhibit tremendous cytotoxicity towards cancer cells. Thus, the present invention provides novel platinum agents that have a different molecular target than those in the art.

They are prepared from solventless metal aliphatic acryl alkoxides. The metal acryl alkoxides are synthesized from exchanging acryl alcohol with metal alkoxides, and are hydrolyzed into metal oxide nanoparticles and are well dispersed in the acrylate matrix. Then they are polymerized into organic/inorganic hybrid materials containing metal oxide in polyacrylate.
