  • Human herpesvirus type 6 protein p100, the corresponding DNA sequences, their preparation and use
    Patent number: 5827519
    Abstract: The invention relates to the human herpesvirus type 6 protein p100 and parts thereof having its specific immunological properties. It further relates to antibodies directed to them and to the corresponding DNA sequences. They can be used in pharmaceutical or diagnostic compositions, optionally together with other HHV-6 proteins or the corresponding DNA sequences.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: October 27, 1998
    Assignee: Behring Diagnostics GmbH
    Inventors: Frank Neipel, Bernhard Fleckenstein

  • Peptide of the structural phosphoprotein (pp 150) of human cytomegalovirus, and DNA encoding said peptide
    Patent number: 5728578
    Abstract: The phosphorylated structural protein of molecular weight about 150 kd (pp 150) of human cytomegalovirus (HCMV) is highly immunogenic and is reliably recognised by human antisera. This protein can, after assignment and sequencing of the gene, be prepared, in whole or in immunogenic sections, by gene manipulation. Proteins of this type are suitable as reagents, for example in an ELISA, and as constituents of vaccines.

  • Pharmaceutical compositions containing as active substance sulphur-containing carboxylic acids and their use in combating retroviruses
    Patent number: 5334612
    Abstract: Pharmaceutical compositions containing at least one compound of Formula I, ##STR1## where X is a hydrogen atom or both X's represent a direct link between the two sulphur atoms; Y is hydrogen or C.sub.1 -C.sub.6 alkyl and n represents a number from 1 to 10, or their pharmaceutically acceptable salts including .alpha.-lipoic acid and dihydrolipoic acid. The pharmaceutical compositions are useful for the treatment of diseases caused by retroviruses.
