  • Patent number: 5122458
    Abstract: The present invention relates to the use of the polyadenylation signal from the gene for bovine growth hormone to achieve a high level of expression of peptides in eukaryotic cells. Accordingly, the present invention provides a recombinant DNA compound comprising: a first nucleotide sequence which contains a promoter capable of initiating transcription of a gene; a second nucleotide sequence which encodes a gene for a polypeptide other than bovine growth hormone, including genomic and other intron containing forms thereof; a third nucleotide sequence which contains a bovine growth hormone polyadenylation signal; and a fourth nucleotide sequence which optionally contains a selectable marker. The first, second and third sequences are operably linked in sequence to form a functional genetic unit capable of being expressed. The fourth sequence, which is optionally provided, is useful for determining whether or not the DNA of the present invention has been incorporated into a living cell.

  • Patent number: 4465639
    Abstract: Addition of controlled amounts of water to the reaction mixture produced by phosgenation of a mixture of polymethylene polyphenyl polyamines (and like polyamines produced by condensation of formaldehyde and aromatic amines) prior to complete removal of excess phosgene gives rise to the corresponding polymethylene polyphenyl polyisocyanates having significantly improved properties. Not only is the color of the product, and of polyurethane foams prepared therefrom, significantly lighter but the proportion of higher molecular weight products is significantly less and the viscosity is less. No undesirable by-products are introduced into the polyisocyanate as a result of the process.

  • Patent number: 4459420
    Abstract: The present invention provides a total synthesis of known intermediates useful in the synthesis of khellin and antiatherosclerotic analogs thereof from pyrogallol. Pyrogallol is converted to 3,6,7-benzofurantriol triacetate using zinc chloride and chloracetanitrile, then catalytically reduced and deactoxylated at the 3 position to yield the corresponding 2,3-dihydrofuran. This substance is subjected to a Fries rearrangement to the corresponding diol, the phenolic hydroxyl group of which is then selectively alkylated. This yields 6-hydroxy-7-alkoxy-5-benzofuranyl methyl ketone, a known intermediate for the production of 4-desmethoxy khellin and analogs thereof. This compound is then selectively alkoxylated at the 4 position using lead tetraacetate or thallium (III) nitrate in an alkanol solvent to yield known chemical intermediates in the preparation of khellin and analogs thereof.

  • Patent number: 4448816
    Abstract: Described are compounds characterized by the following formula: ##STR1## wherein C.sub.n H.sub.2n is alkylene from 2 to 12 carbon atoms and C.sub.m H.sub.2m is alkylene from 2 to 20 carbon atoms. Each of the alkylene groups can, optionally, be substituted by inert substituents. The compounds contain a free isocyanato group and a masked isocyanate group, namely, the cyclic urea moiety, which, when the compounds are heated, preferably in the presence of a catalyst, opens to give the group OCN--C.sub.n H.sub.2n --. Thus, the compounds can be reacted via the free isocyanate group with active hydrogen-containing monomers or polymers to form storage stable compositions which, upon heating, are curable via reaction with the cyclic urea group.

  • Patent number: RE31671
    Abstract: Polyurethane polyether-based elastomers are described which are thermoplastic, recyclable and have increased high temperature resistance which permits fabrication by injection molding. The elastomers are the product of reaction of 4,4'-methylenebis(phenyl isocyanate), a particular group of polypropylene oxide-polyethylene oxide block copolymers and an extender [straight chain aliphatic diols C.sub.2-6 or the bis(2-hydroxyethyl ether) of hydroquinone or resorcinol]. The block copolymers have at least 50 percent primary hydroxyl groups, a pH in the range of 4.5 to 9, a content of alkali metal ion less than 25 ppm and a molecular weight of 1000 to 3000. The minimum ethylene oxide (E.O.) residue content (percent by weight) of the polyether for any molecular weight (M.W.) is governed by the equation: ##EQU1## In a particularly preferred embodiment the elastomers are prepared by replacing up to 25 percent by equivalents of the extender by certain diols (polyethylene glycols up to 1500 M.W. preferred).
