Publication number: 20120177592Abstract: A method of developing degradable linear poly(ethylene glycol) PEG (DPEG) with multiple functioning capacities, which can be used as drug carriers for cancer cell delivery. A DPEG may be effective in targeting cancerous tumors through an enhanced permeation and retention effect (EPR). The DPEG will then degrade in the acidic extracellular fluid of solid tumors leading to fast cellular internalizations, finally degrading in the lysosome for efficient renal clearance. These may be used in conjunction with drugs and/or targeting groups. Furthermore, DPEGs are thermoresponsive, on an as needed basis, making them useful for in vivo application.Type: ApplicationFiled: May 30, 2008Publication date: July 12, 2012Applicant: UNIVERSITY OF WYOMINGInventors: Maciej Radosz, Youqing Shen

Patent number: 7358323Abstract: A water-soluble, flame retardant polyester resin is obtained by a condensation reaction or a polycondensation reaction of a dicarboxylic-acid component, a glycol component, a water-solubility imparting component and a reactive phosphorus-containing compound such that a ratio of the water-solubility imparting component in a total of the dicarboxylic-acid component and the water-solubility imparting component is in a range of 1 to 60 mol %. Since this polyester resin can be dissolved in a solvent by allowing a halogen-free, phosphorus-containing polyester with excellent flame resistance to have water solubility, it is possible to improve applicability and eliminate problems of working environment and environmental destruction resulting from organic solvents. In addition, even when treating substrates such as fibers and PET films with the polyester resin, there is no deterioration of these substrates.Type: GrantFiled: February 10, 2003Date of Patent: April 15, 2008Assignee: Goo Chemical Co., Ltd.Inventors: Koji Maeda, Kouichi Ikegami
