Claims12
A compound which is a pseudotrisaccharide of the formula ##STR17## or a pharmaceutically acceptable acid addition salt thereof, in which X denotes a radical of the formulae ##STR18## Y denotes a radical of the formula ##STR19## U and V both denote hydrogen atoms, or one denotes a hydrogen atom and one denotes a hydroxyl group and
- W and Z both denote hydrogen atoms, or one denotes a hydrogen atom and one denotes a hydroxyl group, or
- Z denotes NHR.sub.6 and
- W denotes a hydrogen atom, and
- R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 independently of one another denote a hydrogen atom or an amino-polyhydroxyalkyl radical derived from an amino sugar which is optionally N-protected and optionally carries C.sub.1 -C.sub.4 -alkyl, carboxylic acid acyl or C.sub.1 -C.sub.6 -alkylidene radicals on one or more OH-groups, at least one of the radicals R.sub.1 to R.sub.5 being other than hydrogen.
