<p>The invention relates to novel disaccharides of formula (I), wherein R1 is selected from the group consisting of hydrogen, linear or branched (C¿1?-C4) alkyl, phenylalkyl with less than ten carbon atoms and -COCH3; R?2¿ is selected from the group consisting of hydrogen, - COCH¿3? and SO3M; R?3¿ is selected from the group consisting of hydrogen, linear or branched (C¿1?-C4) alkyl, phenylalkyl with less than ten carbon atoms, - COCH3 and y -COPh, Ph being phenyl; G is selected from amongst - COOR?4¿ and -COOM, R4 is selected from the group consisting of hydrogen, (C¿1?-C2)-alkyl and arylalkyl with less than sixteen carbon atom; A is selected from the group consisting of hydrogen, -SO3H, -SO3M and -COCH3; B is selected from the group consisting of hydrogen, -SO3H, -SO3M and -COCH3, wherein either A or B are necessarily either -SO3H or -SO3M, M being a an organic or metallic cation. Said compounds can be used as anti-arthritic agents, anti-inflammatory agents or to control blood coagulation.</p> |
