(54) PROCESS FOR THE PREPARATION OF PHOSPHOLIPIDS
(71) We, MAX-PLANCK-GESELLSCHAFT ZUR FdRDERUNG DER
WISSENSCHAFTEN e.V., of 10 Bunsenstrasse, D-3400 Göttingen, Federal
Republic of Germany, a Company of the Federal Republic of Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The present invention is concerned with a process for the preparation of phospholipids, some of which are new.
According to the present invention, there is provided a process for the preparation of phospholipids of the general formula:
in which R is a straight-chained or branched alkyl radical containing up to 5 carbon atoms which is derived from a primary alcohol and can be substituted by one, two or three hydroxyl groups, halogen atoms, amino groups, C1-C,-monoalkylamino or C1-C3 dialkylamino radicals and/or can contain a double or triple bond, A can be
in which R, or R2 is a hydrogen atom or a hydroxyl group and the other symbol R1 or R, or both symbols R1 and R2 signify a -COR11 radical, a -OR12 radical or together a radical of the general formula:
and in which R1 and R2 can be the same or different, in which R11 and R12, which can be the same or different, signify a saturated or unsaturated, straight-chained or branched aliphatic hydrocarbon radical containing up to 25 carbon atoms, which can be substituted by a cycloalkyl radical containing 4 to 8 carbon atoms or by an aromatic radical or by halogen, y is a whole number of from 5 to 32 or wherein A can be a radical of the general formula:
in which R11 has the same meaning as above and x is 0 or a whole number from 2 to 5, or a radical of the general formula:
wherein R11 has the same meaning as above, m is 0 or a whole number of from 2 to 14, p and q, which may be the same or different, are 0 or a whole riumber of from 1 to 14, the sum of p and q giving m, but with the proviso that p+q is not 0 and p+q is not more than 14, wherein a compound of the general formula:
wherein Z can be a hydrogen atom or a methyl radical and w can have a value of from 1 to 6 and preferably of 2, is allowed to react with phospholipase D in the presence of a compound of the general formula ROH, in which R has the same meaning as above, and possibly in the presence of a solvent, whereafter the phospholipid obtained in isolated in known manner as such or in the form of a salt.
Phospholipids and processes for the preparation thereof have been described by
H. Eibl and 0. Westphal in Chem. Phys. Lipids, 3/1939 as well as in German Patent
Specifications Nos. 2,033,357; 2,033,359; 2,033,360, 2,033,361; 2,009,343; 2,345,057; 2,345,059; 2,345,060; 2,437,832 and 2,437,833. These compounds possess valuable pharmacological properties. The lecithin-analogous compounds are strongly surfaceactive materials which possess a great influence on natural cell membranes and on the permeability behaviour of biomembranes. Because of their.excellent boundary surface activity, in the case of per oral or intraperitoneal administration of the compounds to mammals, they change the properties of cell membranes.
Some of these compounds are only available by means of complicated syntheses.
Surprisingly, however, we have now found that the corresponding phosphatidic acid esters of the general formula (I) can be prepared in a simple manner when the compounds of general formula (VIII), i.e. cephalins and phosphatidic acid alkyl esters, as well as their structural analogues, are reacted with phospholipase D.
The compounds of general formula (VIII) employed as starting materials are known and are the subject of earlier Patent Applications (see above). However, hitherto, transesterification reactions have hitheto only been carried out with lecithins and mostly with natural egg lecithin. Therefore, transesterifications with synthetic cephalins, alkyl esters of phosphatidic acid and of structural analogues are of particular interest because, according to the above-mentioned Patent Applications, alkyl esters of phosphatidic acid but also cephalins are very much easier to obtain than the corresponding lecithins. The transesterifications can be carried out preparatively in a very simple manner. Phospholipase D is a very cheap enzyme and can easily be obtained, for example, from white cabbage. With the enzyme obtained from 1 kg. of white cabbage, for example, it is possible quantitatively to convert 100 g. cephalin or phosphatidic acid ester into phosphatidic acid or the desired phosphatidic acid ester.
Phospholipase D from white cabbage does not possess any stereoselectivity; thus, phospholipids with non-natural configuration from the D series can also be reacted in a corresponding manner (see Example 48 hereinafter). In a correspondingly simple manner, it is possible to prepare marked phospholipids by reaction with deuterated or C14-marked alcohols or aminoalcohols.
For the preparation of compounds of general formula (I), in which R signifies a straight-chained or branched alkyl radical containing up to 5 carbon atoms which is derived from a primary alcohol and can possibly be substituted by hydroxyl groups, halogen atoms, for example fluorine, chlorine or bromine atoms, amino groups or CC,-monoalkylamino groups or C1-C,-dialkylamino groups, the appropriate derivatives of general formula (VIII) are reacted with the alcohol of the general formula ROH, in which R corresponds to the desired radical. As alcohols, there can be used, for example, methanol, ethanol, n-propanol, isobutanol, n-butanol and the corresponding pentanols, as well as allyl alcohol or propargyl alcohol. The reaction can only be carried out with primary alcohols which do not contain more than 5 carbon atoms. If rhe alcohols contain more than 5 carbon atoms, then the corresponding phosphatidic acid is the main product of the reaction. The alcohols used can also be substituted; for example, the reaction can also be carried out with glycol, propane1,3-diol, butane-1,4-diol, butane-1,2-diol and the corresponding pentanediols. Furthermore, the reaction can be carried out with fluoroethanol, chloroethanol, bromoethanol, the correspondingly substituted propanols, butanols and pentanols. In addition, the reaction can also make use of ethanolamine, N-methylethanolamine and N,N-dimethylethanolamine, as well as of homologous alkanolamines. The choice of the alcohol components is in no way limited so long as the above-mentioned requirements are fulfilled, i.e. that it is a primary alcohol.
By means of the process according to the present invention, it is possible to prepare a large number of phosphatidic acid derivatives and of phosphatidic acid ester derivatives from a central intermediate compound.
Since defined synthetic cephalins and alkyl esters of phosphatidic acid can be used as starting materials and the reaction gives high yields, it is possible to synthesise a large number of compounds. The reaction can also be carried out with desoxylysocephalins and with desoxylysophosphatidic acid esters, with lysocephalins and with lysophosphatidic acid esters.
When, in rhe above-given general formula (I), A possesses the meaning according to general formula (II), in a simple manner there can be prepared 1 - acyldesoxylysophospholipids ('IX), 1 - acyllysophospholipids (X), 1,2 - diacylphospholipids (XI) and cycloalkylideoketalglycerol - phospholipids (XII):
In the above-given general formulae, R11 can be a straight-chained or branched, saturated or unsaturated aliphatic hydrocarbon radical. R1l is preferably derived from natural fatty acids and signifies, for example, a stearyl, palmityl, myristyl, undecyl, caprinyl, oleoyl or linolyl radical. However, R11 can, for example, also be a heptyl, octyl, nonyl, decyl, undecyl, lauryl, crotyl, behenyl, or arachidyl radical.
In the compounds of general formula (XI), R,l radicals can be the same or different.
The transesterification of compounds of general formula (VIII) with phospholipase D takes place in known manner. For the preparation of an ester, a corresponding cephalin or phosphatidic acid alkyl ester is dissolved in the appropriate alcohol of the general formula ROH and if desired, a solvent is added to the reaction mixture which does not disturb the reaction. As solvent, there can be used, for example, water or a mixture of water and organic solvent, for example, diethyl ether, diisopropyl ether or a secondary or tertiary alcohols. If desired, a buffer, for example sodium acetate, can be added to the reaction mixture and calcium chloride, followed by the addition of the enzyme phospholipase D. Generally, the reaction is carried out at ambient temperature with stirring or shaking. In this case, the reaction is finished afterabout 12 hours. However, it is also possible to operate at lower or higher temperatures, the reaction time then being correspondingly lengthened or shortened. The course of the reaction can be monitored, for example, by thin layer chromatography.
When the reaction is finished, the reaction mixture can then be worked up in the usual manner. For example, the solvent can be distilled off on a rotary evaporator and the aqueous phase acidified in order to precipitate out the protein. The corresponding phospholipid can be isolated, for example, by extraction.
The following Examples are given for the purpose of illustrating the present invention:
Preparation of phospholipase D from white cabbage.
Leaves of white cabbage are homogenised for 5 minutes (Russel and Stoll homogeniser, U.S.A.; 250 ml. water per 1.6 kg. white cabbage at OOC.). The homogenisate is suction filtered at 0 to 50C. and the green-yellow filtrate centrifuged for 20 minutes at 25,000 g and at 0 to 5"C. The clear supernatant contains about 3 mg. protein/ml.
of solution and is used directly for the transesterification reaction. The enzyme is stored at -200C. and is stable for several months.
Example 1.

hydrolysis with phospholipase D.
In a 500 ml. Erlenmeyer flask, 1 mMol of the corresponding phospholipid (for example, 636 mg SN - 1,2 - dimyristoyl - glycerol - 3 - phosphoric - ethanolamine, 445 mg. palmitoylpropane - 1,3 - diol - phosphoric acid ethyl ester or 472 mg. cyclopentadecylideneketal of glycerol - 3 - phosphoryl - N - N - dimethyl - ethanolamine) is dissolved in 5 ml. sec.-butanol, with gentle warming. The solution is stirred with a magnetic stirrer and the solution is successively mixed with 100 ml. diethyl ether, 50 ml. 0.2M aqueous sodium acetate solution (pH 5.6), 25 ml. distilled water, 5 ml.
1M aqueous calcium chloride solution and 25 ml. phospholipase D (concentration: 3 mg. protein/ml.). As the thin layer chromatogram shews, the reaction has proceeded to completion after about 12 hours shaking at 200C.
The reaction mixture is freed from diethyl ether on a rotary evaporator and the aqueous phase is mixed with 50 ml. 1N sulphuric acid in order to precipitate the protein. By means of the addition of 120 ml. methanol and 100 ml. chloroform, followed by vigorous shaking, the phospholipid is extracted into the chloroform phase. The chloroform phase is separated off and the aqueous phase again extracted with 50 ml.

methanol and with 150 ml. 0.5M aqueous sodium ethylenediaminetetraacetate solution (pH 10) and well shaken in order also to remove traces of calcium ions. The chloroform phase is separated off, briefly dried over anhydrous sodium sulphate and then evaporated on a rotary evaporator. The white residue is pure phosphatidic acid or a corresponding analogue (sn - 1,2 - dimyristoyl - glycerol - 3 - phosphoric acid, palmitoyl - propane - 1,3 - diol - phosphate or cyclopentadecyl - ketone - glycerol - 3phosphate, for example). The residue is treated with acetone in order to remove traces of water. The residue is the chromatographically pure product. In general, the yield is 90 to 95% of theory.

compounds by transesterification of phospholipase D.
In a 500 ml. Erlenmeyer flask, 1 mMol of the corresponding phosphoryl - Nmethylethanolamine (for example 636 mg. SN - 1,2 - dimyristoyl - glycerol - 3phosphoryl - ethanolamine, 445 mg. palmitoyl - propane - 1,3 - diol - phosphoric acid ethyl ester or 472 mg. cyclopentadecylideneketal of glycerol - 3 - phosphoryl - N,Ndimethylethanolamine) is dissolved in 25 ml. methanol. While stirring, there are successively added 100 ml. diethyl ether, 50 ml. 0.2M aqueous sodium acetate solution (pH 5.6), 5 ml. 1M aqueous calcium chloride solution and 25 ml. phospholipase D (concentration 3 .mg. protein/ml.). The thin layer chromatogram shews that the reaction has proceeded to completion after 8 to 12 hours.
The reaction mixture is transferred to a separating funnel and mixed with 25 ml.
1N hydrochloric acid, 100 ml. diisopropyl ether and 50 ml. methanol. It is well shaken up and the ethereal phase then filtered through a fluted filter paper. The filtrate contains the methyl ester of the phosphatidic acid or of the analogous starting compound. -For the removal of traces of calcium ions and for the complete conversion into the sodium salt, the ethereal phases are treated with 100 ml. 0.5M aqueous sodium ethylenediamine - tetraacetate solution (pH 10). After phase separation, the ethereal phase is removed, briefly dried with anhydrous sodium sulphate and evaporated on a rotary evaporator. The The~-residue is recrysillised from acetone or methyl eiliyl ketone and consists of pure methyl ester of the corresponding starting compound. The yields amount to 90 to 95% of theory.
