Patent number: 11846640Abstract: The present invention is directed to a novel method of determining inhibitors of proteolytically active coagulation factors, referred to herein as anticoagulants, in a sample, in particular the qualitative detection of direct thrombin and factor Xa inhibitors in a sample. The method of the present invention allows a qualitative determination of the nature anticoagulants present in a sample. This can be achieved with only one coagulation-based test. The method can be used in a test kit, including a point-of-care (POC) system.Type: GrantFiled: April 9, 2019Date of Patent: December 19, 2023Assignee: PENTAPHARM AGInventors: Abel Ferrandez, Anne Brisset

Patent number: 6994984Abstract: A hematological assay is described in which the blood coagulation potential of a body fluid is assessed by reacting a sample of the body fluid with an amount of an activator reagent comprising: (a) a predetermined amount of factor Xa or a hematologically equivalent mutant thereof, and (b) a predetermined amount of factor Va, a hematologically equivalent mutant thereof or an enzyme activating endogenous factor V, (c) (optionally) phospholipids. The reagent may be dry (e.g. lyophilised) or in an aqueous solution preferably buffered to a pH from 6 to 10 (preferably 7 to 8), if desired incubating, if necessary inducing coagulation by the addition of one or more coagulation accelerants such as calcium chloride, and establishing a value indicative of the coagulation potential, e.g. by measuring the time to clotting on an optical coagulometer or through use of a chromogenic substrate. It is preferred to use at (b) factor V activator from purified Russell's Viper venom (RVV-V).Type: GrantFiled: December 14, 2000Date of Patent: February 7, 2006Assignee: Pentapharm AGInventors: Patrizia Maria Gempeler, Andreas Calatzis

Patent number: 6495336Abstract: The invention relates to oligopeptide derivatives whose C-terminal amino acid is arginine which is linked to the remainder of an electroactive aniline or aminoquinoline derivative by an amide bond. The oligopeptide derivatives are split by enzymes of the class of peptide hydrolases, especially proteinases and their inhibitors, of the coagulation system, the fibrinolytic system and the complement system. These oligopeptide derivatives serve as substrates for quantitatively determining such enzymes, especially thrombin, in complex sample liquids, especially capillary blood. This determination is carried out by measuring the increase in the water-soluble amperogenic aniline or aminoquinoline compound. The oligopeptide derivatives and their salts can be produced according to usual methods in peptide chemistry.Type: GrantFiled: November 21, 2001Date of Patent: December 17, 2002Assignee: Pentapharm AGInventors: Christian Ludin, Peter Wikstroem, Lars G.
