    • This invention relates to novel biologically active molecules which bind to and inhibit thrombin. These molecules comprise a catalytic site directed moiety (CSDM) of formula (I), wherein X is hydrogen or is characterized by a backbone chain consisting of from 1 to 100 atoms; R1 is selected from the group consisting of unsubstituted, mono-substituted, di-substituted and tri-substituted saturated ring structures; R2 is a bond or is characterized by a backbone chain consisting of from 1 to 5 atoms; R3 is a bond or is characterized by a backbone chain consisting of from 1 to 3 atoms; R4 is any amino acid; R5 is any L-amino acid which comprises a guanidinium- or amino-containing side chain group; R6 is a non-amide bond; and Y is characterized by a backbone chain consisting of from 1 to 9 atoms; or the formula (II), wherein R1' is selected from the group consisting of unsubstituted, mono-substituted, di-substituted and tri-substituted ring structures; R4' is any amino acid comprising a side chain group characterized by the capacity to accept a hydrogen bond at a pH of between about 5.5 and 9.5; and X, R2, R3, R5, R6 and Y are defined as above. Preferred thrombin inhibitors are further characterized by an anion binding exosite associating domain (ABEAM) and a linker portion of between 18 ANGSTROM and 42 ANGSTROM in length which connects the Y to the ABEAM. This invention also relates to compositions, combinations and methods which employ these molecules for therapeutic, prophylactic and diagnostic purposes.

    • This invention relates to novel, biologically active peptide derivatives which inhibit the fibrinolytic, but not the amidolytic activity of thrombin. The peptide derivatives, which display partial homology to the carboxy terminal portion of hirudin, are characterized by a modified tyrosine or cysteine residue at a predetermined site in the molecule. This invention also relates to compositions and methods employing such peptide derivatives for therapeutic, prophylactic or diagnostic purposes. This invention also relates to platelet and endothelial cell inhibitory compositions and methods characterized by the above-described peptide derivatives or similar peptide derivatives which do not contain a modified cysteine or tyrosine residue at a corresponding locus in the molecule. These methods and compositions are advantageously useful for decreasing or preventing platelet aggregation and platelet activation in a patient or in extracorporeal blood, especially in patients who have a history of heparin-induced thrombocytopenia.
    • 本发明涉及抑制纤维蛋白溶解而不是凝血酶的酰胺分解活性的新型生物活性肽衍生物。 与水蛭素的羧基末端部分显示部分同源性的肽衍生物的特征在于分子中预定位点处的修饰的酪氨酸或半胱氨酸残基。 本发明还涉及使用这些肽衍生物用于治疗,预防或诊断目的的组合物和方法。 本发明还涉及血小板和内皮细胞抑制组合物和方法,其特征在于在分子中相应基因座处不含修饰的半胱氨酸或酪氨酸残基的上述肽衍生物或相似的肽衍生物。 这些方法和组合物有利于减少或预防患者或体外血液中的血小板聚集和血小板活化,特别是在具有肝素诱导的血小板减少症史的患者中。

    • This invention relates to novel, biologically active peptides which display the anticoagulant activity of hirudin. More specifically, it relates to peptides which are homologous to at least a portion of the carboxy terminal 26 amino acids of hirudin. Such peptides may also be characterized by a modified tyrosine residue. This invention further relates to covalent and peptidomimetic analogs of these peptides which display anticoagulant activity. This invention also relates to compositions, combinations and methods using such peptides or analogs for therapeutic, prophylactic or diagnostic purposes. And this invention relates to novel methods for sulfating tyrosine residues contained within the peptide or polypeptide.
