  • Patent number: 6057123
    Abstract: Proteinaceous molecules with stem cell inhibition activity are analogues of LD78 or MIP-1.alpha. which have mutations to prevent or reduce multimer formation beyond certain stages (for example a dodecamer). Aggregate formation is therefore inhibited, and the resulting low molecular weight monomers (or oligomers) have improved solution properties leading to enhanced productivity and greater therapeutic utility as stem cell protective agents, which are useful in tumour therapy.
    Type: Grant
    Filed: March 8, 1993
    Date of Patent: May 2, 2000
    Assignee: British Biotech Pharmaceuticals Limited

  • Patent number: 5965697
    Abstract: This invention relates to mutants of human RANTES (hRANTES) which, relative to the wild-type molecule, have a reduced tendency to aggregate into large multimeric complexes at physiological ionic strength and pH, and are less pro-inflammatory.
    Type: Grant
    Filed: September 25, 1997
    Date of Patent: October 12, 1999
    Assignee: British Biotech Pharmaceuticals Limited
    Inventors: Lloyd George Czaplewski, Michael George Hunter, Richard Mark Edwards, Keith Martyn Dawson
  • Patent number: 5925568
    Abstract: Stem cell inhibitors such as murine and human macrophage inflammatory protein-1alpha (muMIP-1alpha and huMIP-1alpha/LD78) and their analogues and variants enhance the release and mobilization of haematopoietic cells. This property makes them useful in enhancing responses against infection and in cell harvesting.

  • Patent number: 5688664
    Abstract: A plasminogen analogue activatable by thrombin to have plasmin activity which contains the cleavage site sequence (SEQ ID NO: 23): ##STR1## where Xaa at position 1 represents P4; Xaa at position 2 represents P3; Xaa at position 5 represents P1'; and Xaa at position 6 represents P2' where P3 is a basic amino acid residue, P4 is a hydrophobic amino acid residue and each of P1' and P2' is independently a non-acidic amino acid residue, said site being cleavable by thrombin between Arg and P1'.
