  • Publication number: 20210261608
    Abstract: Methods of producing multiple protein products from blood-based materials including alpha-1-proteinase inhibitor, gamma globulin, albumin, and other proteins are described herein. The inventive methods include steps of: salt fractionation, chromatography, ultrafiltration, diafiltration, solvent-detergent treatment, and sterile filtration. Advantageously, the inventive methods are simple and produce alpha-1-proteinase inhibitor, gamma globulin, albumin, and other proteins in high yields. The sequence of process steps can be selected to obtain multiple products from various in-process materials, such as supernatants, pastes, chromatography flow-though, and chromatography washes.

  • Patent number: 6447747
    Abstract: Process for the preparation of radiohalogenated radiopharmaceuticals by an electrophillic substitution, preferably halogenodestannylation reactions, by the reaction of an organometallic substituted precursor, preferably a trialkyl tin substituted precursor, with a radioactive halogen, preferably a radioactive iodine, astatine or bromine composition, in the presence of a catalytically effective amount of an anion selected from the group consisting of bromide, chloride and nitrite anion in an acid medium with an oxidizing agent.

  • Patent number: 4035499
    Abstract: 5,10-Dihydro-imidazo(1,2b)isoquinolines substituted in the 2- and/or 3-position(s) by an aromatic group have analgesic, anti-inflammatory or anti-pyretic activity. Except for 2-phenyl-5,10-dihydroimidazo(1,2b)isoquinoline, they are believed to be novel compounds. They can be prepared in manner known per se by heating a 2-acylmethyl isoquinolinium salt with an ammonium salt of an organic acid or by reaction of a 3-amino-1,4-dihydroisoquinoline with an .alpha.-halogenocarbonyl compound.
