摘要:
The invention relates to synthetic polysaccharides in an acid form and their pharmaceutically acceptable salts, the anionic form of which complies with one of the formulas (I) to (V) described in claim 1. Said polysaccharides can be used in the treatment of diseases linked to coagulation disorders.
摘要:
The invention relates to a pentasaccharide in an acid form and its pharmaceutically acceptable salts, the anionic form of which is described by formula (I), in which R1 is (C1-C3) alkyl; R is hydrogen, an -SO3- group, (C¿1?-C3) alkyl or (C2-C3) acyl; T is hydrogen or an ethyl group; and n is 1 or 2.
摘要:
The invention concerns novel synthetic polysaccharides, with antithrombotic activity, having at least a covalent bond with biotin or a biotin derivative and a method using avidin or streptavidin for neutralising said polysaccharides.
摘要:
The invention relates to a carbohydrate derivative having formula (I) wherein R1 is (1-4C)alkoxy; R?2, R3 and R4¿ are independently (1-4C)alkoxy or OSO¿3?-; the total number of sulfate groups is 4, 5 or 6; and the twisted lines represent bonds either above or below the plane of the six-membered ring to which they are attached; or a pharmaceutically acceptable salt thereof. The compounds of the invention have antithrombotic activity and may be used for treating or preventing thrombosis and for inhibiting smooth muscle cell proliferation.
摘要:
Synthetic polysaccharides are disclosed containing 8-24 monosaccharide units made up of a concatenation of disaccharides consisting of a uronic acid and a hexose, wherein the hydroxyl groups of the polysaccharides are etherified with a C1-6 alkyl group or esterified in the form of a sulpho group, each disaccharide being at least monoetherified; and salts thereof, are disclosed.

摘要:
The invention concerns the use of direct or indirect selective inhibitors of the Xa factor acting via antithrombin III, on their own or combined with one or several compounds with platelet antiaggregating activity, for preparing medicines for preventing or treating arterial thromboembolism. The invention also concerns pharmaceutical compositions containing one or several direct or indirect selective inhibitors of Xa factor acting via antithrombin III in association with one or several compounds with platelet antiaggregating activity, and, optionally one or several pharmaceutically acceptable carriers.

摘要:
A synthetic polysaccharide including an antithrombin III binding domain consisting of a concatenation of five monosaccharides supporting a total of two carboxylic acid functions and at least four sulpho groups, said domain being directly bound at the non-reducing end by a thrombin binding domain including a concatenation of 10-25 monosaccharide units selected from hexoses, pentoses or deoxy sugars of which all the hydroxyl groups are etherified by a C1-6 alkyl group or esterified in the form of sulpho groups, as well as salts and particularly pharmaceutically acceptable salts thereof, are disclosed.
