摘要:
The present invention has as its objects a new derivative of the aminoglycoside family, namely N.sub.1 [L-(-)2-hydroxy-4-amino butyroyl]4-0[2',6'-diamino 2',6'-didesoxya, D glucopyranosyl]6-0[3"-methylamino 3",4",6"-tridesoxy .alpha., D-xylohexopyranosyl]2-desoxy streptamine, as well as its mineral or organic acid addition salts, its process of preparation and methods of treatment using the same.
摘要:
The present invention relates, by way of new industrial products, to the benzylphenyl osides of the formula ##STR1## in which: X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5, which are identical or different, each represent a hydrogen atom, a halogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 alkyl group substituted by one or more halogen atoms (in particular a CF.sub.3 group), an OH group, a C.sub.1 -C.sub.4 alkoxy group, a C.sub.1 -C.sub.4 alkoxy group substituted by one or more halogen atoms, a nitro group, a group NR'R" (in which R' and R", which are identical or different, each represent the hydrogen atom, a C.sub.1 -C.sub.4 alkyl group or an acetyl group), a methylthio group, a methylsulfinyl group or a mesyl group, andR represents an ose radical chosen from the group comprising(a) the .alpha.-L-rhamnosyl radical,(b) non-hydrolyzable monosaccharide radicals and(c) non-hydrolyzable monosaccharide radicals in which the hydroxyl group on the carbon atom in the 2-position is replaced with an amine group, the hydroxyl and amine groups of the group R being capable of acetylation, and their addition salts in cases where at least one of the groups X.sub.1, X.sub.2, X.sub.3, X.sub.4, X.sub.5 and R comprises a basic radical.These new products are useful in therapy. They can be prepared by reducing the corresponding benzoylphenyl and .alpha.-hydroxybenzylphenyl osides.
