  • Patent number: 4591596
    Abstract: This invention relates to chemical products of general formula ##STR1## wherein R is an amino group, mono or bi-hydroxyalkyl substituted, or a thio group, mono hydroxyalkyl substituted, in which one or more of the available --OH groups have been esterified with acids containing 2 to 18 carbon atoms.It is also described a process for the preparation of said products, which comprises reacting a corresponding starting compound, N or S-hydroxyalkyl substituted, with the chloride or the anhydride of the acid concerned.
    Type: Grant
    Filed: November 17, 1983
    Date of Patent: May 27, 1986
    Assignee: E.N.I. Ente Nazionale Idrocarburi
    Inventors: Walter Marconi, Francesco Bartoli, Franco Morisi, Francesco Pittalis
  • Patent number: 4353996
    Abstract: Fibres for biological uses can be produced by adding to a spinnable solution of a polymer selected from among many of the most common polymers and copolymers, a substance selected from among anti-platelet aggregation substances, anticoagulants and substances having a similar action. The substances can also be applied as a surface outer layer to articles made with the polymeric substances.

    Filed: September 23, 1980
    Date of Patent: October 12, 1982
    Assignee: Snamprogetti, S.p.A.
    Inventors: Walter Marconi, Francesco Bartoli, Franco Morisi, Francesco Pittalis
  • Patent number: 4336357
    Abstract: Polyamide materials for the construction of protheses and surgical sundries are made biocompatible by inducing a superficial hydrolysis by treating such materials, either raw or in the form of shaped articles, with a normal multiple solution of hydrogen chloride. Thrice normal or fourfold normal solutions are preferred and the treatment time being a function of the temperature. At human body temperature (37.degree. C.) a treatment time from 30 to 60 minutes will do.

    Filed: July 28, 1980
    Date of Patent: June 22, 1982
    Assignee: Snamprogetti, S.p.A.
    Inventors: Francesco Bartoli, Walter Marconi, Franco Morisi, Francesco Pittalis
  • Patent number: 4263180
    Abstract: A method is disclosed for embedding sequestering agents in filamentary structures, the method comprising the steps of preparing an emulsion formed by an aqueous or nearly aqueous solution of the sequestering agent and a solution of the filament-forming polymer in an appropriate solvent, and spinning the emulsion in a coagulation bath.

    Filed: June 4, 1976
    Date of Patent: April 21, 1981
    Assignee: Snamprogetti S.p.A.
    Inventors: Walter Marconi, Francesco Bartoli, Silvio Gulinelli, Franco Morisi, Delio Zaccardelli
  • Patent number: 4248704
    Abstract: Phenylalanine level in blood or another medium is considerably reduced and can even be annulled by causing blood or the other medium to flow through a mass of porous fibers in which the enzyme phenylalanine ammonia lyase has been occluded: the fibers have been previously made biocompatible, if necessary.
    Type: Grant
    Filed: May 3, 1979
    Date of Patent: February 3, 1981
    Assignee: Snamprogetti S.p.A.
    Inventors: Walter Marconi, Francesco Bartoli, Roberto Gianna, Franco Morisi, Giuseppina Spotorno
  • Patent number: 4243776
    Abstract: Biocompatible articles are obtained by treating a polymeric material with a hydrolyzing agent on its surface and covalently binding thereon a biological agent, such as an anti-platelet-aggregation agent.
    Type: Grant
    Filed: June 21, 1978
    Date of Patent: January 6, 1981
    Assignee: Snamprogetti S.p.A.
    Inventors: Walter Marconi, Francesco Pittalis, Francesco Bartoli, Franco Morisi
  • Patent number: 4242461
    Abstract: For effecting enzymic reaction, a reactor is disclosed, in which the flow of the solution to be treated through the catalytic bed material takes place radially. It is preferred to have the catalytic bed in the form of coils of enzyme-occluding fibers. The coils are variously piled up within the reactor. High outputs, low pressure drops and more than satisfactory conversion rates are obtained.

    Date of Patent: December 30, 1980
    Assignee: Snamprogetti S.p.A.
    Inventors: Francesco Bartoli, Franco Morisi, Delio Zaccardelli
  • Patent number: 4100029
    Abstract: A method is disclosed for improving the activity of oxireductase enzymes, the improvement consisting in that an enzyme and a previously functionalized coenzyme are embedded in a filamentary structure, the coenzyme having previously been attached to a water-soluble, high-molecular-weight polymer.

  • Patent number: 3964970
    Abstract: A process for the preparation of only one of the two stereoisomer forms carbamyl amino acids is provided wherein certain heterocyclic compounds having an assymmetrical carbon, such as 5-substituted hydantoins, are hydrolyzed in the presence of certain enzymes, such as dihydropyrimidinase extracted from calf liver. In another embodiment of the invention, the corresponding amino acids are provided by hydrolyzing the carbamyl amino acids in the presence of these same enzymes.
