Definitions
- the invention relates to new enantiomerically pure phosphocompounds which have an inhibitory effect on the enzymatic activity of phospholipase A 2 and a process for their preparation, and also pharmaceutical preparations which contain such inhibitors.
- Phospholipase A 2 is an enzyme that cleaves the sn-2 acyl bond of phospholipids. This enzyme is therefore involved in the formation of a large number of substances which trigger biological reactions, in particular in the formation of arachidonic acid and lysophospholipids.
- a large number of biochemically active compounds are formed from arachidonic acid by enzymatic oxidation, which are summarized under the term eicosanoids, including prostagladins, tromboxanes, prostacyclins and leukotrienes. These different classes of compounds cause a large number of biochemically important reactions. For this reason, inhibitors of PLA 2 are of great interest for the development of new anti-inflammatory drugs or drugs which influence blood clotting. The aim of the invention is therefore to provide inhibitors for PLA 2 .
- R 1 is a C. * •• - to C 22 - and in particular a C ** 6 - to C * 8 -alkyl radical, with a hexadecyl radical being particularly preferred.
- R 4 is a C * -C ** 7 alkyl radical.
- the compounds according to the invention are phosphocholines, phosphoethanolamines, phospho- (methyl) ethanolamines, phospho- (N, N-dimethyl) ethanolamines, phosphoinositols (D or L), Phosphoglycerols (D or L), phosphoserines (D or L), phospho- (N-methyl) -serines (D or L), phospho- (N, N-dimethyl) -serines (D or L), phospho- (N, N, N-trimethyl) -serines (D or L), phosphoglycols, phosphatidic acids, methyl phosphates, ethyl phosphates, 1,3-propanediol phosphates and 1,2-propanediol phosphates.
- the new compounds are also drugs for combating tumors and protozoan and fungal diseases. They are also suitable for the therapy of autoimmune diseases and bone marrow damage. s
- the invention also relates to a process for the preparation of such phosphatidyl compounds by reacting
- phosphocholine-amino or phosphocholine-hydroxy product is used with an aceticating agent containing the radical R 4 to give the corresponding O-phospho-N-acyl or O-phospho-O-acyl Product implemented.
- the compounds of the invention are pure in terms of their enantiomers. Since the PLA 2 works enantioselectively, the desired enantiomer or a mixture of the enantiomers can be used for PLA 2 modulation by means of the method according to the invention. It has been shown that the substances according to the invention which have a long aliphatic chain (for example the octadecane derivatives) can penetrate very well into cells in order to develop their effect there. Compounds which have a short acyl chain are particularly suitable. Surprisingly, those substances according to the invention which have an unnatural configuration and / or which contain the free amino or hydroxyl function in the molecule have a particularly pronounced inhibitory effect.
- the substances according to the invention which have a long aliphatic chain for example the octadecane derivatives
- Compounds which have a short acyl chain are particularly suitable.
- the reaction scheme illustrates the representation of the 1-phospho-2-ester compounds. Since the introduction of the acyl group takes place in the last step of the synthesis - Ag - the polar phosphoric acid ester groups must not contain any free hydroxyl or amino groups.
- the target compounds are substances with a free 2-hydroxyl group caused by the reaction sequence Aa - Af can be obtained, then the above restriction does not apply.
- y means a number from 7 to 19
- x means a number from 0 to 19.
- the reaction scheme describes the preparation of 1 phospho-2-amide compounds. Since the introduction of the acyl group takes place in the last step of the synthesis - Bg -, the polar phosphoric acid ester groups must not contain any free hydroxyl or amino groups.
- the target compounds are substances with a free 2-amino group that can be obtained by the reaction sequence Ba - Bf, then the above restriction does not apply.
- the synthesis steps Ba) - Bc) correspond to the synthesis steps Aa) to Ac)
- the synthetic route is modified in the following way: Instead of the reaction Ae, the free hydroxyl group in the 1-position of the corresponding intermediate is replaced by the reaction sequence mesylation and substitution by ammonia in the 1- Amino compound converted, which is then acylated. By debenzylation in the 2-position and exposure of the hydroxyl group, the phosphorylation can now take place in the 2-position.
- the diagram describes the representation of the l-phospho-2-ester compounds.
- the fatty acid - Cg - is introduced before the phosphorylation - Ci.
- target compounds can be produced which have free hydroxyl or amino groups in the polar region, for example phosphoethanolamine, phosphoglycerol etc.
- the synthesis steps Ca - Cc correspond to the reactions Aa - Ac. Tr-0 OH) I
- the above synthesis route is modified in the following manner: a) instead of reaction step Cg, phosphorylation is carried out in the 2-position and the end product with free 1- Hydroyl group debenzylated; b) Instead of the reaction step Ce, the 1-hydroxyl group according to Mitsunobu (Mitsunobu 0., M. Wada and T. Sano, Stereospecific and stereoseletive reactions. I. Preparation of amines from alcohols. J. Am. Chem. Soc.
- This reaction scheme is suitable for the preparation of l-phospho-2-amide compounds.
- the amide formation - Dg - occurs before the phosphorylation -Di. It can also be used to prepare compounds which carry hydroxyl or amino groups in the polar region, for example phosphoethanolamine, phosphoglycerol etc.
- the synthesis steps Da - Dd correspond to the reactions Ba - Bd. HO NPhth
- the invention also relates to pharmaceutical preparations which contain the substances according to the invention.
