Nitro Or Nitroso Containing Patents (Class 568/76)
  • Publication number: 20150147396
    Abstract: Nanoparticles are provided that comprise S-nitrosothiol (SNO) groups covalently bonded to the nanoparticles and/or S-nitrosothiol containing molecules encapsulated within the nanoparticles, as well as methods of making and using the nanoparticles. The invention also provides methods of preparing nanoparticles comprising Snitrosothiol (SNO) groups covalently bonded to the nanoparticles, where the methods comprise a) providing a buffer solution comprising chitosan, polyethylene glycol, nitrite, glucose, and hydrolyzed 3-mercaptopropyltrimethoxysilane (MPTS); b) adding hydrolyzed tetramethoxysilane (TMOS) to the buffer solution to produce a sol-gel; and c) lyophilizing and ball milling the sol-gel to produce nanoparticles of a desired size.

  • Publication number: 20080287686
    Abstract: An 'onium salt, e.g. a quaternary ammonium salt, of an anionic dye maybe prepared by mixing an aqueous solution of a salt of the dye with a solution of a water-insoluble 'onium salt in an organic solvent, and separating a solution of the 'onium salt of the anionic dye in the organic solvent from the residual aqueous solution.

  • Patent number: 6417347
    Abstract: A method for producing a S-nitrosylated species is provided. The method comprises: (a) providing a deoxygenated, alkaline aqueous solution comprising a thiol and a nitrite-bearing species; (b) acidifying the solution by adding acid to the solution while concurrently mixing the solution (e.g., by vigorously stirring the solution) to produce the S-nitrosylated species; and (c) isolating the S-nitrosylated species. The nitrite-bearing species can be, for example, an inorganic nitrite, such as an alkali metal nitrite, or an organic nitrite, such as an alkyl nitrite (e.g., ethyl nitrite, amyl nitrite, isobutyl nitrite or t-butyl nitrite). The thiol is preferably a thiol-containing polysaccharide, a thiol-containing lipoprotein, a thiol-containing amino acid or a thiol-containing protein, and more preferably a thiol-containing polysaccharide such as thiolated cyclodextrin. In many preferred embodiments, the S-nitrosylated species is insoluble in the acidified solution, precipitating upon formation.

  • Patent number: 6255277
    Abstract: A method for preventing adverse effects associated with the use of a medical device in a patient by introducing into the patient a device of which at least a portion includes a prophylactic or therapeutic amount of a nitric oxide adduct. The nitric oxide adduct can be present in a matrix coating on a surface of the medical device; can be coated per se on a surface of the medical device; can be directly or indirectly bound to reactive sites on a surface of the medical device; or at least a portion of the medical device can be formed of a material, such as a polymer, which includes the nitric oxide adduct. Also disclosed is a method for preventing adverse effects associated with the use of a medical device in a patient by introducing the device during a medical procedure and before or during said procedure locally administering a nitric oxide adduct to the site of contact of said device with any internal tissue.
