## Abstract

The invention concerns new substituted aminoalkanol phospholipids of the general Formula I ##STR1## and methods for the treatment of humans suffering from high blood-pressure (hypertension), from inflammatory illnesses, from tumors and/or atherosclerosis by administering medicaments containing such a compound as well as methods for plant protections.

## Background
The present invention concerns new substituted aminoalkanol phospholipids and methods for using the same.

The compounds of the invention correspond to the general formula I ##STR2## wherein X represents an oxygen or a sulphur atom and Y represents the radical --NR.sup.1 R.sup.2 or --OR.sup.3, wherein R.sup.1, R.sup.2 can be the same or can be different from each other and represent a saturated or unsaturated, straight-chained or branched alkyl radical having 1 to 20 carbon atoms, a benzyl radical, a phenyl radical or hydrogen; and R.sup.3 stands for phenyl, benzyl or C.sub.1-4 -alkyl; R.sup.4, R.sup.5, R.sup.6 can be the same or can be different from each other and stand for hydrogen or a low alkyl radical having 1 to 4 carbon atoms; 1 represents an integer from 0 to 19, m represents an integer from 2 to 6, and n an integer from 2 to 4.

Compounds according to the invention are, for example:

The compounds according to the invention are biologically very active and can be used, for example, in medicaments and plant protective preparations. The new compounds exhibit a strong pharmacological action. In particular, they exhibit a blood pressure reducing and immuno-regulating action. They can be used, therefor, for treating in particular hypertension, but also for treating inflammatory illnesses and for the therapy of atherosclerosis.

For producing the new ureidoalkyl phospholipids wherein l and m are as in Formula I, are reacted in an inert organic solvent, such as for example, ether, tetrahydrofuran, dioxane, acetone, chloroform, dimethylformamide, with a benzyl halide or chloroformic acid benzyl ester preferably in the presence of an auxiliary base, such as, for example, pyridine, dimethyl-aminopyridine, triethylamine, an alkali metal hydroxide, or alkaline earth metal oxide, to form compounds of the general Formula III.

The reaction may also be performed in two phases, possibly with the use of a phase-transfer catalyst. The compounds III wherein R.sup.7 is benzyl and m is 2, can also be produced from N-benzylalkyl amines and ethylene oxide. The compounds II are obtainable either by the reaction of the appropriate amines with ethylene oxide or by the reduction of N-acyl-W-aminoalkanols.

The compounds of the general Formula III ##STR3## wherein l and m are the same as in Formula I and R.sup.7 represents a radical separable by hydrogenation, such as, for example, benzyl or benzyloxycarbonyl, are converted according to methods known per se to the phospholipids of the general Formula IV ##STR4## wherein R.sup.4, R.sup.5, R.sup.6, l, m and n are the same as in Formula I and R.sup.7 is the same as in Formula III. Compounds of Formula IV wherein R.sup.7 is benzyloxycarbonyl correspond to compounds of Formula I wherein R.sup.3 is benzyl. For example, the compounds III can be phosphonylated with dichlorophosphoric acid-.omega.-alkyl halide esters of Formula V ##STR5## wherein n is the same as in Formula I and Hal is a chlorine or bromine atom, in an inert organic solvent, possibly, using an auxiliary base, and the product can subsequently be reacted with an amine of Formula VI ##STR6## wherein R.sup.4, R.sup.5, R.sup.6 are the same as in Formula I, in an inert organic solvent, possibly, under pressure, to form the compounds of Formula IV (see H. K. Mangold, Angew.Chem.. 91, 550-560 (1979); H. Eibl, Chem. and Phys. of Lipids, 26, 405-429 (1980).

The compounds of Formula IV can also be produced by reacting compounds of Formula III with phosphorus oxytrichloride and then with an alkane diol of Formula VII

in which n is the same as in Formula I, possibly with the introduction of auxiliary bases, such as, for example, triethyl amine, and using inert solvents, such as, for example, tetrahydrofuran, to form cyclic intermediate products of Formula VIII ##STR7## wherein l, m, n and R.sup.7 are the same as in Formula IV (see H. Eibl, `Phospholipid Synthesis` in Knight (publisher), Liposomes, Elsevier 1981, pages 19-50).

The intermediate products of Formula VIII can also be prepared by reacting compounds of Formula III with a cyclic phosphor compound of Formula IX ##STR8## wherein n is the same as in Formula I, in an inert organic solvent with the addition of an auxiliary base [N. S. Chandrakumar et al., Tetrahedron Lett. 23, 1043-46, (1982); Biochim. Biophys. Acta 711, 357-360 (1982)].

The intermediate products VIII can be converted in a simple manner, for example, by treating with an amine of Formula VI in an organic solvent, possibly under pressure, to compounds of Formula IV (N. T. Thuong and P. Chabrier, Bull. Soc. Chim. Fr. 1974, 667-671).

The compounds of the Formula IV are hydrogenated with hydrogen in a suitable organic solvent, such as, eg, methanol, ethanol, ether dioxane or mixtures thereof and with water accompanied by separation of the benzyl group in the presence of a conventional hydrogenation catalyst, such as, for example, palladium/active carbon, whereby the compounds of the general Formula X ##STR9## wherein R.sup.4, R.sup.5, R.sup.6, l, m and n are the same as in Formula I, develop.

The compounds of Formula X are reacted with carbonic acid derivatives of Formula XI or XII ##STR10## wherein R.sup.1, R.sup.2 and X are the same as in Formula I, either in substance or in an inert organic solvent, such as, eg, dimethylformamide, chloroform, N-methylacetamide, possibly with the addition of a catalyst, such as, eg, dimethylaminopyridine or of a base, such as, eg, pyridine, triethylamine, in particular when compounds of Formula XII are used, to form the compounds of Formula I of the invention.

The compounds of Formula I wherein R.sup.1 .dbd.R.sup.2 .dbd.H, can be produced suitably in aqueous or aqueous-organic media, such as, eg, water/dioxane, with the use of alkalicyanates, possibly with the addition of an organic or inorganic acid, preferably acetic acid, analogously to the known urea syntheses (see, eg, Weygand-Hilgetag, Org. Chem. Experimentierkunst, publishing house J. A. Barth-Leipzig, 1970, p.420) from compounds of Formula X.

The compounds of Formula I in which R.sup.1 =benzyl and R.sub.2 =H, and X=O can also be hydrogenated with hydrogen in a suitable organic solvent, such as, eg, methanol, ethanol, ether, dioxane or mixtures thereof and with water, accompanied by the separation of the benzyl group in the presence of a conventional hydrogenation catalyst, such as, eg, palladium/active carbon, whereby compounds of Formula I in which R.sup.1 .dbd.R.sup.2 .dbd.H develop.

For producing the new (aryl)alkyloxy carbonyl aminoalkanol phospholipids of Formula I, N-alkyl-amino alcohols of Formula II are reacted in an inert organic solvent, such as, eg, ether, tetrahydrofuran, dioxane, acetone, chloroform, dimethyl formamide, with chloroformic acid benzyl ester, chloroformic acid phenyl ester or chloroformic acid alkyl ester, preferably in the presence of an auxiliary base, such as, eg, pyridine, dimethyl amino pyridine, triethyl amine, alkali hydroxide, alkaline earth oxide, to form compounds of the general Formula XIII ##STR11##

The compounds of Formula XIII wherein R.sup.3, l and m are the same as in Formula I, are converted according to methods known per se to the phospholipids of the general Formula I.

The compounds of Formula XIII can be phosphorylated, eg, with dichlorophosphoric acid-.omega.-alkyl halide esters of Formula V in an indifferent organic solvent, possibly using an auxiliary base, and subsequently converted to compounds of Formula I by reacting with an amine of Formula VI in an indifferent organic solvent, possibly under pressure.

The compounds of formula I can also be prepared by phosphorylating compounds of Formula XIII with phosphorus oxytrichloride and subsequently converting the product with an alkane diol of Formula VII, possibly with the introduction of auxiliary bases, such as, eg, triethyl amine, and with the use of inert solvents, such as, eg, hydrofuran, and with the use of indert solvents, such as, eg, tetrahydrofuran, to cyclic intermediate products of Formula XIV ##STR12## wherein l, m, n and R.sup.3 are the same as in Formula I.

The intermediate products XIV can be converted to the compounds of Formula I in a simple manner, eg, by treating with an amine of Formula VI, in an organic solvent, possibly under pressure. The Compounds of Formula I can also be prepared by reacting compounds of of Formula X with chloroformic acid esters in inert solvents, such as, eg. chloroform, dimethyl formamide, possibly with the addition of an auxiliary base, such as, eg, pyridine, triethyl amine.
