agent Site-directed pegylation of arginases and the use thereof as anti-cancer and anti-viral agents By www.freepatentsonline.com Published On :: Tue, 13 Aug 2013 08:00:00 EDT Mono-pegylated arginase conjugate and method producing thereof. The mono-pegylated arginase is homogeneous in molecular weight and shows therapeutic effect for treating cancers and viral infections. The method of producing such arginase conjugate has a main step of genetically modifying the gene encoding an arginase so that the PEG moiety can attach to the enzyme at a predetermined, specific intended site. This is achieved by removing the PEG attaching amino acid residues at undesirable sites while keeping (or adding, if necessary) the one at the desirable site of the enzyme. Two exemplary mono-pegylated arginase conjugates so produced are human arginase I (HAI) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys45 of the enzyme and Bacillus caldovelox arginase (BCA) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys161 of the enzyme.

agent Therapeutic agent for fibromyalgia containing etanercept By www.freepatentsonline.com Published On :: Tue, 20 May 2014 08:00:00 EDT Disclosed is a drug effective in the treatment of fibromyalgia. Basically, the disclosed therapeutic agent was created on the basis of experiments showing improvement in symptoms when etanercept was administered to patients suffering from fibromyalgia. Etanercept is known as a therapeutic agent for rheumatoid arthritis, and the JFIQ score of patients not suffering from fibromyalgia improved considerably in the preferred embodiment. In other words, a therapeutic agent for fibromyalgia is disclosed that contains etanercept as an active ingredient in an effective amount. Full Article
