Abstract

The present invention provides phospholipids of the general formula: ##STR1## wherein X is a valency bond, an oxygen or sulphur atom or a sulfonyl, sulfinyl, phenylene, cycloaklylene, carbonylamino, aminocarbonyl, ureido or carbonyl group, R.sub.1 is a hydrogen atom or a straight-chained or branched, saturated or unsaturated aliphatic hydrocarbon radical containing up to 18 carbon atoms, which is optionally substituted one or more times by halogen, alkoxy, alkylthio, alkanesulfinyl, alkanesulfonyl, carbalkoxy or phenyl, R.sub.2 is a straight-chained or branched, saturated or unsaturated divalent aliphatic hydrocarbon radical containing up to 18 carbon atoms, which is optionally substituted one or more times by halogen, alkoxy, alkylthio, alkanesulphinyl, alkanesulphonyl, carbalkoxy or phenyl, Y is an oxygen atom or a --O--CO--O--, --O--CO--NH-- or --O--CS--NH-- group, R.sub.3 is a straight-chained or branched, saturated or unsaturated divalent aliphatic hydrocarbon radical containing 2 to 8 carbon atoms, which can also be part of a cycloalkane ring system and is optionally substituted one or more times by hydroxyl, halogen, alkylthio, alkanesulphinyl, alkanesulfonyl, nitrile, alkox…
