摘要： By ultrafiltration of an aqueous solution wherein there have been formerly dissolved alfa-cyclodextrin and a raw lipidic mixture, the latter characterized in that it contains monosialoganglioside (GMl) either as the sole ganglioside or otherwise in a prevailing quantity over the other associated gangliosides, and after the removal of cyclodextrin at the end of the process, it is obtained GMl with a titer of at least 95%. The present invention concerns also the intermediate complex that it is being formed between the hereabove said monosialoganglioside and alfa-cyclodextrin.

摘要： Novel derivatives are disclosed as obtained from chondroitin sulfate, dermatan sulfate and hyaluronic acid, having a molar ratio between sulfate groups and carboxylic groups like that of heparin and furthermore characterized by possessing, as the heparin, the sulfoamino group at the carbon atom at the 6 position of hexosamine.The novel compounds show a very remarkable clearing activity in comparison with the starting mucopolysaccharides, this activity being similar and for some derivatives comparable with that of heparin.Moreover, differently from what normally happens upon sulfating the sulfomucopolysaccharides, the anticoagulating activity of the novel compounds is negligible or anyhow very reduced.The compounds of the present invention find use in the therapy of arteriosclerosis.

摘要： The present invention provides a new class of compounds presenting a high compatibility with tissues and organic fluids. Such new compounds are polysaccharides essentially formed of units of uronic acid and/or hexosamine, containing nitro groups —ONO2 covalently bonded to the saccharide structure. Preferably, the polysaccharides according to the invention are prevalently formed of disaccharide repeating units formed of uronic acid and hexosamine. These compounds, in psychological conditions, selectively release NO, allowing a reduction in the amount of NO needed to achieve a determined therapeutical effect. This result has been achieved by functionalizing polysaccharides essentially formed of units of uronic acid and/or hexosamine, with subsituents containing a ONO2 ? group.
