Abstract
Compounds of formula (I): ##STR1## in which: R.sub.1 or R.sub.4, which are identical or different, represent hydrogen or alkyl, PA0 R.sub.2 represents hydrogenm or alkyl, hydroxymethyl, --CH.sub.2 OPO(OH).sub.2 or --CH.sub.2 OPO(ONa).sub.2, PA0 R.sub.3 represents hydrogen, alkyl or hydroxyl or any one of the following groups: ##STR2## in which: T represents oxygen or sulfur, PA1 n represents an integer between 1 and 4, PA1 R.sub.5 represents hydrogen or alkyl, PA0 X represents nitrogen, CH or CR'.sub.3 (in which R'.sub.3 has the same meaning as R.sub.3 except in the case where R.sub.3 represents hydroxyl), PA0 A represents alkylene of formula --(CH.sub.2).sub.p -in which p represents an integer between 2 and 4, optionally substituted by one or more linear or branched (C.sub.1 -C.sub.4) alkyl, or any one of the following radicals: ##STR3## Y and Z together form oxygen or simultaneously represent two hydroxyl and in this case, the compound of formula (I) is positively charged, their isomers as well as their addition salts with a pharmaceutically acceptable acid or base.
