    摘要: Applicant has isolated a Factor X a inhibiting substance from the salivary gland extract of the leech H. ghilianii . The extract is subjected to separation using both DEAE-cellulose and heparin-agarose chromatography resins eluting with an increasing salt gradient. The extract is subjected to affinity chromatography using Factor X a bound to an Affi-Gel-15 resin eluting with HEPES containing benzamidine. Reverse phase chromatography yields several purified peptides or proteins having Factor X a inhibiting activity. The properties and clinical compositions of these FX a inhibitors are described.

    摘要: Novel peptides having a fragment containing 2 or 3 Arg or Lys residues and having a fragment containing 2 or 3 Gly, Leu, Ile, or Thr residues adjacent to the carboxy end of the first fragment and having amino and carboxy tails consisting of chains made up of any amino acids are immunosuppressant agents and can suppress the lymphocyte system by suppressing lymphocyte proliferation.
    The formula is as follows:
          Tn-A-B-C-D-Tc
    wherein
          Tn is an amino terminal residue selected from hydrogen, one or two alkyl groups of from 1 to 6 carbon atoms, one or two acyl groups of from 2 to 10 carbon atoms, carbobenzyloxy, and t -butyloxy­carbonyl;
          A is a peptide fragment containing from 3 to 12 residues of any amino acid;
          B is a peptide fragment containing 2 or 3 amino acid residues selected from Arg and Lys;
          C is a peptide fragment containing 2 or 3 amino acid residues selected from Gly, Leu, Ile, and Thr;
          D is a peptide fragment containing from 1 to 12 residues of any amino acid; and
          Tc is a carboxy terminal residue selected from OH, (C₁-C₆)alkoxy, amino, mono- or di-(C₁-C₄)alkyl substituted amino, and benzylamino.
