Title:
PHOSPHOLIPID, MANUFACTURE AND ANTICANCER CONTAINING SAME
Document Type and Number:
Japanese Patent JPS5810592
Kind Code:
A
Abstract:
The present invention provides phospholipids of the general formula: wherein X is a valency bond, an oxygen or sulphur atom or a sulfonyl, sulfinyl, phenylene, cycloaklylene, carbonylamino, aminocarbonyl, ureido or carbonyl group, R1 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, R2 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, R3 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, alkoxycarbonyl, carboxamido optionally substituted by alkyl radicals, cycoalkyl, optionally substituted phenyl or alkoxy, which in turn is optionally substituted by phenyl, hydroxyl, alkoxy, alkylthio, alkanesulfinyl, alkanesulfonyl, optionally acylated amino, alkoxycarbonyl, nitrile or carboxamido optionally substituted by alkyl radicals, Z is an oxygen or sulfur atom, R4 is a straight-chained or branched alkylene radical containing 2 to 5 carbon atoms and R5 is a hydrogen atom or a lower alkyl radical, with the proviso that when X is a valency bond, R1 and R2 together represent an unsubstituted, straight-chained or branched, saturated or unsaturated divalent aliphatic hydrocarbon chain containing up to 18 carbon atoms, Y, R4 and R5 have the above-given meanings and Z is an oxygen atom, R3 cannot be a propylene or 2-methylpropylene chain optionally substituted by hydroxyl, alkoxy or benzyloxy and with the proviso that when X is a valency bond, R1 and R2 together signify an alkyl radical containing up to 18 carbon atoms and substituted by halogen or phenyl, Y and Z are oxygen atoms and R4 and R5 have the above-given meanings, R3 cannot be a propylene or 2-hydroxypropylene chain; and the pharmacologically acceptable salts thereof. The invention also provides pharmaceutical compositions containing such compounds, having cancerostatic action without inducing thrombocyte aggregation.
