Patent number: 7687646Abstract: The present invention provides a novel polymorphic form of olopatadine hydrochloride ([(Z)-3-(dimethylamino)propylidene]-6,11-dihydrodibenz[b,e]oxepin-2-acetic acid hydrochloride), a selective histamine H1-receptor antagonist that is used for the treatment of ocular symptoms of seasonal allergic conjunctivitis. The present invention also provides novel methods for producing olopatadine on a large scale, and in a manner that is cost effective, provides a low level of impurities and eliminates the need to use the costly and dangerous base, butyllithium, which is used in prior art reactions for making olopatadine. The present invention further provides novel processes for carrying out a large scale production of 3-dimethylaminopropyltriphenylphosphonium bromide and its corresponding hydrobromide salt, which are employed in the production of olopatadine, and pharmaceutically acceptable salts of olopatadine.Type: GrantFiled: March 28, 2006Date of Patent: March 30, 2010Assignees: Azad Pharmaceutical Ingredients, AG, Universität ZürichInventors: Thomas Bader, Hans-Ulrich Bichsel, Bruno Gilomen, Imelda Meyer-Wilmes, Mark Sundermeier

Patent number: 7601685Abstract: Proteins are incorporated into protein or polysaccharide matrices for use in tissue repair, regeneration and/or remodeling and/or drug delivery. The proteins can be incorporated so that they are released by degradation of the matrix, by enzymatic action and/or diffusion. As demonstrated by the examples, one method is to bind heparin to the matrix by either covalent or non-covalent methods, to form a heparin-matrix. The heparin then non-covalently binds heparin-binding growth factors to the protein matrix. Alternatively, a fusion protein can be constructed which contains a crosslinking region such as a factor XIIIa substrate and the native protein sequence. Incorporation of degradable linkages between the matrix and the bioactive factors can be particularly useful when long-term drug delivery is desired, for example in the case of nerve regeneration, where it is desirable to vary the rate of drug release spatially as a function of regeneration, e.g.Type: GrantFiled: December 17, 2002Date of Patent: October 13, 2009Assignees: Eidgenossische Technische Hochschule Zurich, Universitat ZurichInventors: Jeffrey A.

Patent number: 7550648Abstract: The present invention discloses a method and an in-vivo assay system useful for the identification and testing of modulating agents as well as for the validation of therapies of neurodegenerative diseases associated with the formation of neurofibrillary tangles, in particular Alzheimer's disease. The present invention is based on the surprising finding that injection of ?-amyloid A?42 fibrils into brains of P301L mutant tau transgenic mice caused several-fold increases in the numbers and an accelerated production of neurofibrillary tangles in cell bodies predominantly within the amygdala. The induced neurofibrillary tangles occurred as early as 18 days after A?42 injections and displayed striking features of neurofibrillary tangles of several human neurodegenerative diseases, particularly Alzheimer's disease.Type: GrantFiled: October 23, 2007Date of Patent: June 23, 2009Assignee: Universitat ZurichInventors: Jürgen Götz, Roger Nitsch, Feng Chen

Publication number: 20090131862Abstract: A device and a method for accurate and remote dispensing of a radioactive liquid are disclosed. A source of a radioactive liquid (1) and a source of a flushing liquid (5) are selectively connected to a fluid delivery path (7, 8, 10) by way of valve means (V1). An activity metering unit (9) is operable to determine a level of radioactivity in a metering section (8) of the fluid delivery path downstream from the valve means (V1). The device is operated by transporting a first amount of radioactive liquid (1) to the metering section (8), using the activity metering unit (9) to measure a reference level of radioactivity, calculating a second amount of the radioactive liquid still to be delivered such that the first and second amounts of radioactive liquid together have some predetermined level of radioactivity, and delivering the first and second amounts of radioactive liquid to the destination (11).Type: ApplicationFiled: July 14, 2005Publication date: May 21, 2009Applicant: UNIVERSITAT ZURICHInventors: Alfred Buck, Bruno Weber
