Patent number: 5756540Abstract: In accordance with the present invention, there are provided methods for the in vivo reduction of nitric oxide levels in a mammalian subject. In contrast to the inhibitory approach described in the prior art (i.e., wherein the function of the enzymes responsible for nitric oxide production is inhibited), the present invention employs a scavenging approach whereby overproduced nitric oxide is bound in vivo to a suitable nitric oxide scavenger. The resulting complex renders the nitric oxide harmless, and is eventually excreted in the urine of the host. Further in accordance with the present invention, there are provided compositions and formulations useful for carrying out the above-described methods. An exemplary nitric oxide scavenger contemplated for use in the practice of the present invention is a dithiocarbamate-ferrous iron complex. The present invention relates to methods for reducing in vivo levels of .multidot.NO as a means of treating subjects afflicted with inflammatory and/or infectious disease.Type: GrantFiled: June 2, 1995Date of Patent: May 26, 1998Assignee: MCW Research Foundation, Inc.Inventor: Ching-San Lai

Patent number: 5413786Abstract: Blood coagulation is accelerated by contacting blood with an accelerator of hydrolase activity. The activation of the precursors of serine protease including Factor XII and the enzyme activity of serine protease is accelerated. The accelerator is a metal complex containing a ligand which is a cyclic compound having a five- or six-membered ring containing carbonyl groups adjacent to each other. Examples of such ligands are oxidized alkylgallate, partially or totally oxidized ellagic acid, partially or completely oxidized 1,4- di(3,4-dihydroxyphenyl) 2,3-dimethylbutane, 1,2,3-triketohydroindene and isatin. The metal of the complex is preferably Fe, Co, Ni, or Al. The complex may be combined with a hydrolase as a co-accelerator of coagulation, an organic acid having an amino salt and/or a quaternary nitrogen or an antifibrinolysis agent and/or an anti-plasmin agent.Type: GrantFiled: October 13, 1993Date of Patent: May 9, 1995Assignee: Sekisui Kagaku Kogyo Kabushiki KaishaInventor: Hideo Anraku

Patent number: 5407660Abstract: Nuclear magnetic resonance (NMR) imaging of body organs and tissues is enhanced by administering to a living animal body a diagnostic composition comprising a diagnostically effective amount of a substantially nontoxic paramagnetic image altering agent containing a chelate of a paramagnetic element such as magnesium, gadolinium or iron, carried by a liposome. The chelate is carried by or within or outside the external surface of the liposome in such a manner that after arrival at or delivery to the desired organ or tissue site, the paramagnetic image altering agent is released in a diagnostically useful fashion.Type: GrantFiled: November 12, 1993Date of Patent: April 18, 1995Assignee: Mallinckrodt Medical, Inc.Inventors: Mark E. Bosworth, Ronald M. Hopkins

Patent number: 5393777Abstract: Methods for removing ferric iron from aqueous liquids and for performing deferration therapy are disclosed, involving the use of a novel siderophore, termed anguibactin. Anguibactin is isolated from a marine pathogen, Vibrio anguillarum, containing the pMJ1 plasmid. Anguibactin inhibits iron uptake by living cells, wrests iron from vertebrate tissues, removes iron from other siderophores and ferric hydroxide, and removes ferric iron from aqueous solutions, including cell-culture media. For deferration therapy, anguibactin from which bound iron has been removed is administered by dissolving in water or other liquid aqueous pharmaceutical carrier at a dosage typical for other siderophores. Anguibactin is preferably administered intramuscularly or subcutaneously, but can be given intravenously.Type: GrantFiled: November 15, 1990Date of Patent: February 28, 1995Assignee: State of Oregon Acting by and through the State Board of Higher Education on behalf of Oregon Health Sciences UniversityInventor: Jorge H.
