Disclosed are compounds having the formula (I) wherein R2 is hydrogen, a monomeric glycoside or an oligomeric glycoside, R3 is hydrogen, a monomeric glycoside, an oligomeric glycoside, or a group having the formula (II), R is a lower alkylene, R' is selected from the group consisting of moieties having the formula (III), (IV) and (V) where X = 0 or 1, Y = 0 or 1, R1 is hydrogen or a pharmacologically active drug residue, R8 a pharmacologically active drug residue, R4, R5, and R6 are independently hydrogen, alkyl, aryl, aralkyl, and cycloalkyl or together form a nitrogen-containing ring, and R7 is hydroxyl or hydroxyalkyl.

La présente invention se rapporte à des composés représentés par la formule (I), dans laquelle R¿2? représente hydrogène, un glycoside monomère ou un glycoside oligomère, R¿3? représente hydrogène, un glycoside monomère, un glycoside oligomère ou un groupe représenté par la formule (II), R représente un alkylène inférieur, R' est sélectionné parmi les groupes caractéristiques représentés par les formules (III), (IV) et (V), dans lesquelles X = 0 ou 1, Y = 0 ou 1, R¿1? représente hydrogène ou un résidu de médicament pharmaceutiquement actif, R¿8? représente un résidu de médicament pharmaceutiquement actif, R¿4?, R¿5? et R¿6?, pris indépendamment, représentent hydrogène, alkyle, aryle, aralkyle et cycloalkyle, ou, pris conjointement, forment un cycle contenant de l'azote, et R¿7?représente hydroxyle ou hydroxyalkyle.
