  • Patent number: 6610655
    Abstract: Cyclic pentapeptides are disclosed having the following formula (I)-Cyclo(-A1-A2-A3-A4-A5-)-wherein A1, A2, A3, A4 and A5 are amino acid residues. The pentapeptide has amino acid residues in positions 1-2-3 to form a &ggr;-turn, and amino acid residues in positions 3-4-5-1 to form a &bgr;-turn in combination with the &ggr;-turn. D-&agr;-amino acid residues are selected for A1, A3, and A5 and L-&agr;-amino acid residues are selected for A2 and A4. Compounds having &ggr;-turns and &bgr;-turns can be synthesized, regardless of the kinds of amino acid residues, and it is possible to synthesize compounds in which desired amino acid residues are introduced into sites of &bgr;-turn and &ggr;-turn based on their importance from the viewpoint of biological activity.

  • Patent number: 5958716
    Abstract: The present invention provides a method for indicating von Willebrand factor deficiency in a blood sample or platelet-rich plasma sample which exhibits abnormal platelet function comprising (a) adding a von Willebrand factor preparation to the sample, and (b) testing the sample for platelet function. In this method, the von Willebrand factor preparation restores normal platelet function and indicates that the sample initially lacked the von Willebrand factor. The von Willebrand factor preparation comprises purified von Willebrand factor. The invention also discloses a method which further comprises separating the blood sample into a plasma layer and cellular component layer and removing the plasma layer, prior to the step of adding a von Willebrand factor preparation to the sample. In this embodiment the von Willebrand factor preparation comprises platelet-poor plasma containing a normal level of von Willebrand factor.
