| 摘要 |
This invention refers to new disaccharides of formula (I), (see formula I) where R1 is selected from the group consisting of hydrogen, linear or bran-ched (C1-C4)-alkyl, phenylalkyl of less than ten carbon atoms and -COCH 3; R2 is selected from the group consisting of hydrogen, -COCH3 and SO3M; R3 is selected from the group consisting of hydrogen, linear or branched (C1--C4)-alkyl, phenylalkyl of less than ten carbon atoms, -COCH3 and -COPh , where Ph is phenyl; G is selected from between -COOR4 and -COOM, whe-re R4 is selected from the group consisting of hydrogen, (C1-C2)-alkyl a nd arylalkyl of less than sixteen carbon atoms; 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; where either A or B are necessarily either -SO3H or -SO3M, and where M is an organic or me-tallic cation. These compounds can be used as anti-arthrosic or anti--inflammatory drugs or to control blood clotting.
