The phenyl boronate ester, boronamide and boronate thioester groups are represented by one of the following structural formulas: Ar in Structural Formulas (I) and (II) is substituted or unsubstituted; and each Z is —O—, —NH— or —S— and is independently selected. Pharmaceutically acceptable salts of the polymer are also included. The aryl boronate ester, boronamide or boronate thioester can be cleaved to release the corresponding aryl boronic acid. Also disclosed are pharmaceutical compositions comprising the polymers of the present invention and a pharmaceutically acceptable carrier or diluent; and methods of treating a subject for obesity with the polymers of the present invention.Type: GrantFiled: June 27, 2002Date of Patent: May 9, 2006Assignee: Genzyme CorporationInventors: Stephen Randall Holmes-Farley, W. Harry Mandeville, III, Pradeep K. Dhal, Chad Cori Huval, Xinhua Li, Steven Craig Polomoscanik

Patent number: 6956095Abstract: The invention relates to the preparation of aryl-aryl coupled compounds and materials. These materials play an important role in industry, for example as liquid crystals, pharmaceuticals and agrochemicals, to mention just a few application areas. These compounds, in particular, are also of major importance especially in the high-growth area of organic semi-conductors (for example, applications in organic or polymeric light-emitting diodes, organic solar cells, organic ICs).Type: GrantFiled: December 2, 2002Date of Patent: October 18, 2005Assignee: Covion Organic Semiconductors GmbHInventors: Kevin Treacher, Philipp Stössel, Hubert Spreitzer, Heinrich Becker, Aurelie Falcou
