Definitions
- the invention relates to the use of exogenous glycosaminoglycans, their analogs, as well as their fractions, fragments and derivatives, for the preparation of medicaments intended for the treatment of thrombocytopenia.
- Glycosaminoglycans are polysaccharides formed essentially by the regular repetition of the disaccharide sequence [uronic acid (D-glucuronic or L-iduronic) - » hexosamine (glucosamine or galactosamine)]. These products exist in several forms: heparin and heparan sulfate, chondroitin sulfate (4- S and 6-S), dermatan sulfate and hyaiuronic acid. The first three are variously substituted by sulfate groups; hyaiuronic acid does not contain a sulfate group.
- glycosidic bonds between the different osidic motifs vary according to the forms and are of types 1-4 or 1-3 (Casu B. in Advances in Carbohydrate Chemistry and Biochemistry, Académie press Inc. 1985, 43, pp 51-133; Ruoslahti & Yamaguchi, Cell, 1991, 64 pp 867-869).
- Glycosaminoglycans are components of cells and the extracellular matrix. They carry significant negative charges giving them an ability to fix a certain number of substances of cationic nature. As a result, they have multiple biological activities.
- glycosaminoglycans products such as: dextran sulfate, pentosan polysulfate, sulfated alginic acid, sulfated lactobionic acid, polyvinyl sulfate and sucralfate. These products also often have interesting pharmacological properties.
- glycosaminoglycans have been the subject of numerous studies, which have made it possible to highlight several biological activities. These activities are: anticoagulant activity, the ability to complex various proteins, activity in the complement system, activity as regulators and modulators of the development of certain types of cells, vascular or non-vascular and activity on angiogenesis.
- glycosaminoglycans Several pharmaceutical specialties contain as active ingredient glycosaminoglycans, their fragments or derivatives.
- Magnesium heparinate for example, is the active ingredient in a specialty marketed in France under the name Cutheparin®. It is an anticoagulant acting on several coagulation factors and used in the prevention and treatment of thromboembolic disease and thrombogenic states.
- Heparin fragments also known as low molecular weight heparins, are also active ingredients in drugs such as, for example, nadroparin, or dalteparin, enoxaparin, parnaparin or tinzaparin.
- Patent application EP-A-0 037 319 describes such products and their preparation process.
- Patent application EP-A-0 199 033 also describes the use of dermatan sulfate and that of heparan sulfate, alone or in combination, for the prevention or treatment of venous thrombosis or manifestations of arteriosclerosis.
- Dextran sulfate is also used as an anticoagulant (JEF Reynolds "Martindale, The extra Pharmacopeia", 1989, The Pharmaceutical Press, p 1564).
- patent application EP-A-0 270 317 describes low molecular weight dextran sulfate derivatives which exert an inhibitory activity on cell fusion and on viral adsorption, and disclose the advantage of using these products in the treatment and prophylaxis of diseases due to viral infections.
- Sodium hyaluronate is used as an adjunct in anterior chamber eye surgery. This product provides mechanical protection of the cornea and reduces the risk of synechiae formation ("Dictionnaire Vidal", 1992, Edition du Vidal, Paris). This same product is also used in the treatment of arthritis (J.E.F. Reynolds "Martindale, The extra Pharmacopeia", 1989, The Pharmaceutical Press, p 1617).
- the pentosan polysulfate active ingredient of a specialty marketed in France under the name of Hemoclar®, has anticoagulant, fibrinolytic properties and exerts an activity on the release of lipoprotein lipase ("Dictionnaire Vidal", 1992, Edition du Vidal, Paris and 'The
- Chondroitin sulfate a physiological constituent of the cornea, is used in the symptomatic treatment of hypolacrymia.
- the mucin structure of this naturally occurring mucopolysaccharide achieves prolonged adhesion to hydrophobic cells of the eyeball and thus maintains effective protection ("Dictionnaire Vidal", 1992, Edition du Vidal, Paris).
- Chondroitin sulfate also finds its application in the treatment of cardiac ischemia and osteoporosis (J.E.F. Reynolds "Martindale, The extra Pharmacopeia", 1989, The Pharmaceutical Press, p 1556).
- this product has antihyperlipoproteinemic activity ('The Merck Index ", 1989, Merck and Co INC, Rahway N.J, USA, p 344 No. 2217).
- Patent application EP-A-0 287 477 describes heparins of low molecular weight which can be used for the regulation of certain physiological systems such as the inhibition of angiogenesis, the inhibition on the proliferation of smooth muscle cells or having activity anti-complement.
- Oligosaccharides containing at least 5 monosaccharide units consistent with those present in natural heparin and having a specific affinity for cationic or anionic cell growth factors recognizing heparin, are described in patent application EP-A-0244298. These fragments are described as having regulatory activities on cell division and differentiation and find their applications in stimulating the repair of muscle tissue, heart tissue or skin tissue, accelerating the healing of injuries of traumatic origin. , and alone or in combination with steroids, in the inhibition of processes where neoangiogenesis is pathological.
- Megacaryocytopoiesis concerns the engagement of hematopoietic stem cells towards the megakaryocytic line, the proliferation of megakaryocytic progenitors and the maturation of megakaryocytes to give rise to platelets (Mazur EM., Megakaryocytopoiesis and platelet production: A review Exp Hematol., 1987, ⁇ 5, pp 340-350; Hoffman R., Regulation of megakaryocytopoiesis, Blood, 1989, 74, pp 1196-1212). Platelets play a very important role in certain physiological processes, notably blood coagulation (Caen J.P., Cronberg S. and Kubisz P., Platelet physiology and pathology, New-York, Stratton International, 1977).
- megakaryocytopoiesis is directly regulated by a number of hematopoietic growth factors such as "megakaryocyte colony-stimulating factor” (MK-CSF), interleukin-3 (IL3), interleukin-6 (IL6 ), the “granulocyte-macrophage colony-stimulating factor” (GM-CSF) and erythropoietin (Epo). It is also indirectly controlled by interleukin-1 and interleukin-11 (Mazur EM., Exp. HematoL, 1987, 15, pp 340-350; Hoffman R., Blood, 1989, 75, pp 1196- 1212).
- IL3, Epo, and GM-CSF have been used in vivo in normal subjects and patients.
- Their stimulating effects of megakaryocytopoiesis are limited, in particular in aplastic anemias and in secondary hematopoietic insufficiencies (Peters WP. The myeloid colony-stimulating factors, Introduction and overview, Seminars in Hematology, 1991, 28, pp 1-5; Ganser A. et al. , Blood, 1990, 76, pp 1287-1292; Ganser A. et al, Z6, pp 666-676).
- the hematopoietic cord is a complex system made up of cells of different types and functions. Its organization can be conceived in five cell compartments: stem cells of the entire hematopoietic line, hematopoietic progenitor cells, mature hematopoietic cells, the micro-environment and accessory cells. Stem cells by a series of differentiations and maturations give rise to progenitor cells which include megakaryocyte progenitors, the latter in turn giving rise to platelets as indicated above.
- Thrombocytopenia is a well-known condition, especially during cancer chemotherapy. At present, there is no effective and economical treatment to remedy it. It was therefore of prime interest to find a specific and economical way to combat this pathological situation.
- the invention therefore relates to the use, as specific inducers of megakaryocytopoiesis of exogenous glycosaminoglycans, of their analogs, as well as of their fractions, fragments and derivatives, for obtaining medicaments intended for the treatment of thrombocytopenia.
- heparins of porcine or bovine origin extracted from the lungs, from the intestinal mucosa or from any other organ, can be used as unfractionated heparins.
- low molecular weight heparins can be used, nadroparin calcic (DCI) and CY 222 (Laboratoires CHOAY, France; patents FR-2,440,376 and EP-0,037,319), PK 10169 known as also enoxaparin (DCI) (PHARMUKA Laboratories, France; patent application EP-0040 144), dalteparin (DCI) or KABI 2165 (KABI VITRUM, Sweden; Thrombosis Res.
