Patent number: 6153220Abstract: A taste-masked micromatrix powder in which the ratio of a cationic copolymer synthesized form dimethylaminoethyl methacrylate and neutral methacrylic acid esters compared to a drug having poor organoleptic properties is greater than 2 to 1, preferably 4 to 1, most preferably 6 to 1 (wt/wt). Taste masked immediate release micromatrix powders can be formed by spray drying the drug and cationic copolymer whereas sustained release micromatrix powders can be formed by granulating controlled release powders, which can be made by spray drying the drug with a retarding polymer, with the cationic copolymer. The immediate release or sustained release taste-masked powders of this invention can be incorporated into conventional oral dosage forms such as sprinkles, suspension, fast melt tablets, chewable tablets or effervescent tablets.Type: GrantFiled: September 30, 1998Date of Patent: November 28, 2000Assignee: Elan Corporation, plcInventors: Kenneth Iain Cumming, Elaine Harris

Patent number: 6117632Abstract: A method of identifying a peptide which permits or facilitates the transport of an active agent through a human or animal tissue. A predetermined amount of phage from a random phage library or preselected phage library is plated unto or brought into contact with a first side, preferably the apical side, of a tissue sample or polarized tissue cell culture. At a predetermined time, the phage which is transported to a second side of the tissue opposite the first side, preferably the basolateral side, is harvested to select transported phage. This modified phage is amplified in a host. This cycle of events is repeated (using the transported phage produced in the most recent cycle) a predetermined number of times to obtain a selected phage library containing phage which can be transported from the first side to the second side.Type: GrantFiled: November 8, 1996Date of Patent: September 12, 2000Assignee: Elan Corporation, plcInventor: Daniel Joseph O'Mahony

Patent number: 5866396Abstract: There is provided an improved process for the biosynthetic production of indigo, the improvement comprising removing unwanted by-products such as isatin or indirubin from the broth in which such indigo is produced. Isatin can be removed by enzymatic activity using an isatin-removing enzyme such as an isatin hydrolase, or by other techniques such as process parameters (elevated temperature, pH), or by contacting the broth containing the isatin with appropriate adsorption compounds/compositions such as carbon or appropriate resins. Since isatin is the precursor of indirubin, the indirubin levels are decreased as a result of isatin removal.Type: GrantFiled: December 11, 1996Date of Patent: February 2, 1999Inventors: Walter Weyler, Timothy C. Dodge, John J. Lauff, Dan J. Wendt

Patent number: 5814501Abstract: Substantially dust-free enzyme-containing particles are prepared by spray-coating solid particulate cores with a fermentation broth containing enzymes. Fermentation broths containing from 5% to 100% total enzyme solids and 4%-55% total solids content in the broth may be used. For broths containing 4%-31% total solids, enzyme and coating agents may be spray-coated so as to achieve a weight gain of 1%-24% w/w over the initial weight of the cores. For broths with 31%-55% total solids, a corresponding weight gain of 1%-100% may be achieved. The enzyme coated cores may be further coated with coating agents. The total dry weight added to the cores ranges from 1% to 19% in the absence of coating agents and 1% to 24% in the presence of coating agents when the lower range of total solids content is used. The total dry weight added to the cores ranges from 1% to 100% when the higher range of total solids content is used.Type: GrantFiled: February 15, 1995Date of Patent: September 29, 1998Assignee: Genencor International, Inc.Inventors: Nathaniel T. Becker, Richard P. Crowley

Patent number: 5801034Abstract: This invention provides a method for killing cells in fermentation mixtures in order to prepare the fermentation mixture for processing to recover or extract a desired product from the fermentation mixture. A preferred method of this invention comprises in either order, adjusting the pH of the fermentation mixture to a value equal to or less than about two pH units below the pK.sub.a of the compatible organic acid using a mineral acid, and adding a sufficient amount of a compatible organic acid and/or organic acid salt to the mixture to effect a substantially complete cell kill. The method of this invention is useful for killing microorganisms such as yeast, bacteria or fungi in any culture or fermentation mixture and is particularly useful in systems where it is desired to kill the cells without lysing them.Type: GrantFiled: December 14, 1994Date of Patent: September 1, 1998Assignee: Genencor InternationalInventors: Virgil B.
