20110313182 | PHOSPHAPLATINS AND THEIR USE IN THE TREATMENT OF CANCERS RESISTANT TO CISPLATIN AND CARBOPLATIN - The present invention provides phosphaplatins, stable isolated monomeric phosphato complexes of platinum (II) and (IV), and methods of use thereof for treating cancers, including cisplatin- and carboplatin-resistant cancers. Unlike cisplatin, these 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 anti-cancer 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 anticancer agents that have a different molecular target than those in the art. | 12-22-2011 |
20130165680 | Efficient Processes for Large Scale Preparation of Phosphaplatins Antitumor Agents - 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. | 06-27-2013 |

20150361118 | LIGAND COMPOUND, CATALYST SYSTEM FOR OLEFIN OLIGOMERIZATION, AND METHOD FOR OLEFIN OLIGOMERIZATION USING THE SAME - 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. | 12-17-2015 |
