  • Patent number: 6936423
    Abstract: Lethal Toxin Neutralizing Factor has been isolated in purity from opossum serum by high pressure liquid chromatography (HPLC) fractionation. The amino acid sequence from the N-terminal for the first fifteen amino acids of LTNF-n is: Leu Lys Ala Met Asp Pro Thr Pro Pro Leu Trp Ile Lys Thr Glu. Antibodies to LTNF-n and synthetic peptides consisting of fifteen, ten and five amino acids from the N-terminal of the above sequence, designated as LTNF-15, LTNF-10 and LTNF-5 were produced by immunizing Balb/C mice to produce Anti-LTNF-n, Anti-LTNF-15, Anti-LTNF-10 and Anti-LTNF-5. The anti LTNF-n, anti-LTNF-15, anti-LTNF-10 and anti-LTNF-5 react immunologically with all types of toxins derived from animal, plant and bacteria and can be assayed by immunological in vitro test such as ELISA tests. Anti-LTNFs react roughly proportional to lethal dose of biological toxins under in vitro immunological ELISA test similar to the mouse bioassay test.

  • Patent number: 6284871
    Abstract: The present invention relates to biologically active peptides which specifically inhibit the Factor IX-dependent pathway of blood coagulation. These peptides are based on a specific motif which represents a sequence of Factor VIII (amino acid 1811-1818) involved in binding to activated Factor IX as well as to the intact Factor IX zymogen. Binding of said peptides to Factor IX or activated derivatives thereof effectively inhibits complex assembly with Factor VIII. These peptides thereby specifically interfere in the Factor IX-dependent pathway of thrombin formation, while leaving other haemostatic pathways unaffected. By virtue of this unique specificity, the peptides of this invention are particularly useful in novel pharmaceutical compositions for the treatment of thrombotic disorders.

  • Patent number: 6037450
    Abstract: Plasma EPCR has been isolated, characterized and shown to block cellular protein C activation and APC anticoagulant activity. Plasma EPCR appears to be about 43,000 daltons and circulates at approximately 100 ng/ml (98.4.+-.27.8 ng/ml, n=22). Plasma EPCR bound activated protein C with an affinity similar to that of recombinant soluble EPCR (Kd.sub.app approximately 30 nM), and inhibits both protein C activation on an endothelial cell line and APC anticoagulant activity in a one-stage factor Xa clotting assay. Soluble plasma EPCR appears to attenuate the membrane-bound EPCR augmentation of protein C activation and the anticoagulant function of activated protein C. Soluble EPCR has also been detected in urine. Levels of soluble EPCR can rise in inflammatory disease associated with vascular injury and appear to be correlated with inflammation and disease states associated with abnormal coagulation.

  • Patent number: 5837679
    Abstract: Analogs of blood factors which are transiently inactive are useful in treatment of diseases characterized by thrombosis. In addition, modified forms of activated blood factors that generate the active blood factor in serum but have extended half-lives are useful in treating hemophilic conditions. These modified forms of the blood factor may be acylated forms which are slowly deacylated in vivo.

  • Patent number: 5831026
    Abstract: A process for reducing degradation of recombinant coagulation factor VIII caused by metal-dependent proteases requiring Zn.sup.2+ for activity or containing Zn.sup.2+ as an integral part of their structure comprises adding an inhibitor of Zn.sup.2+ dependent proteases to a recombinant factor VIII solution. The recombinant factor VIII solution is obtained after harvesting a conditioned medium from a cell culture used for producing the recombinant coagulation factor VIII. The inhibitor is selected from complexing agents with a stronger affinity for the Zn.sup.2+ ion of the protease than for the ion or ions stabilizing the factor VIII molecule, and compounds structurally related to the natural substrate of the protease and containing an electronegative moiety.

  • Patent number: 5831025
    Abstract: A human Activated Protein C preparation with a high specific activity of 3500 U/mg or more and substantially free from thrombin or other proteases which can convert Protein C into Activated Protein C is provided. A process for preparing this human Activated Protein C, which involves, contacting a solution of human Activated Protein C, after activation of Protein C with thrombin or other activating protease, with a cation exchanger to allow for adsorption of both thrombin or another activating protease and Activated Protein C to the cation exchanger followed by elution of the human Activated Protein C alone.

  • Patent number: 5773417
    Abstract: The invention is directed to human serum albumin-porphyrin (HSA-P) complexes which are capable of reversible oxygen binding and their uses. These complexes may be used in applications requiring physiological oxygen carriers such as in blood substitute solutions, or in applications requiring plasma expanders. Methods for the production of these complexes are provided. In a specific example, HSA-P complexes are shown to exhibit reversible oxygen binding. In another example, the HSA-P complex does not exhibit appreciable vasoactivity.

  • Patent number: 5770199
    Abstract: The invention relates to a pharmaceutical preparation comprising a plasma protein wherein said preparation is free of infectious agents as well as essentially free of denaturation products and is obtainable by a method that encompasses the following steps:a) addition of a polyether and a chaotropic agent to a solution comprising the plasma protein, optional lyophilization of the solution;b) inactivation of infectious agents in the presence of the polyether by a physio-chemical or chemical treatment, andc) removal of the polyether and the chaotropic agent.

  • Patent number: RE38827
    Abstract: This invention is related to an adhesive composition which may be used to bond or seal tissue in vivo. The adhesive composition is readily formed from a two component mixture which includes a first part of a protein, preferably a serum albumin protein, in an aqueous buffer having a pH in the range of about 8.0-11.0 and a second part of a water-compatible or water-soluble bifunctional crosslinking agent. When the two parts of the mixture are combined, the mixture is initially a liquid which cures in vivo on the surface of tissue in less than about one minute to give a strong, flexible, pliant substantive composition which bonds to the tissue and is absorbed in about four to sixty days. The adhesive composition may be used either to bond tissue, to seal tissue or to prevent tissue adhesions caused by surgery.
