Patent number: 5500212Abstract: New bile acid sequestrant polymer compositions and a process for preparing the polymers in particulate form, preferably in spherical form, are described. The polymer particles are prepared by crosslinking an amine-containing polymer with an amount of a polyfunctional amine-reactive compound sufficient to crosslink the polymer so that it is essentially water insoluble and has bile acid sequestering efficacy greater than that of cholestyramine, preferably greater than about three times the efficacy of cholestyramine. A preferred polymerization process revolves suspension polymerization of water-soluble amine-containing monomers, such as dialkylaminoalkyl (meth)acrylate esters and dialkylaminoalkyl (meth)acrylamides, in the presence of polyfunctional amine-reactive compounds, such as substituted dihaloalkanes. Pharmaceutical compositions containing the bile acid sequestrant polymer particles and a method for lowering blood cholesterol levels using the pharmaceutical compositions are also described.Type: GrantFiled: June 6, 1995Date of Patent: March 19, 1996Assignee: Rohm and Haas CompanyInventors: Paul E. Bliem, Larry W. Steffier

8-En-19 11 .beta.-bridged steroids, their production and pharmaceutical preparations containing them
Patent number: 5478956Abstract: 8-En-19,11.beta.-bridged steroids of general formula I ##STR1## that have the 8,9-double bond as a new structural feature, and a process for their production are described. The substituents R.sup.1 R.sup.4 -Y, R.sup.4' -Y.sup.', X and Z have the meaning indicated in the description. The new compounds especially have at their disposal pronounced antigestagen effectivenss and are suitable for the production of pharmaceutical preparations.Type: GrantFiled: September 28, 1993Date of Patent: December 26, 1995Assignee: Schering AktiengesellschaftInventors: Eckhardt Ottow, Gunter Neef, Walter Elger, Martin Schneider, Karl Fritzemeier -
Patent number: 5478955Abstract: The invention is drawn to cholesterol derivatives in which a cyclopentane ring has been introduced onto the 25-carbon of the side chain and to 24-epimers of these compounds. The compounds are useful intermediates in the production of 26,27-dimethylene-1.alpha.,25-dihydroxyvitamin D.sub.2 and 26,27-dimethylene-24-epi-1.alpha.,25-dihydroxyvitamin D.sub.2. These vitamin D derivatives are useful for the treatment of diseases such as osteoporosis.Type: GrantFiled: November 10, 1994Date of Patent: December 26, 1995Assignee: Wisconsin Alumni Research FoundationInventors: Hector F. DeLuca, Naoshi Nakagawa

Patent number: 5446177Abstract: Anti-inflammatory compounds, a method of treating inflamed ocular tissue and compositions of these compounds are described. The compounds are derivatives and analogues of known steroid compounds (e.g., dexamethasone) and are advantageously characterized in that they do not cause any significant increase in intraocular pressure during chronic use.Type: GrantFiled: March 4, 1994Date of Patent: August 29, 1995Assignee: Alcon Laboratories, Inc.Inventor: John J. Boltralik
