Definitions
- the present invention relates to an improved chemical synthesis for the preparation of biologically important compounds. More particularly, the present invention concerns an improved method for the synthesis of glycerol di- and triphosphate derivatives, preferably nucleoside di- and triphosphate esters of glycerol lipids, such as nucleoside diphosphate mono- and diglycerides.
- the glycerol monophosphate amidate intermediates of the new synthesis are novel compounds.
- nucleoside di- and triphosphate esters of glycerol and glycerol derivatives are known in the art. Among them, nucleoside diphosphate diglycerides are of particular importance due to their role in biochemical processes. The synthesis and the biological importance of a naturally- occurring liponucleotide, cytidine diphosphate diglyceride (CDP-DG) in lipid biosynthesis have been well documented since the early 1960's. In eukaryotes, CDP-DG is a precursor of phosphatidylglycerol, cardiolipin and phosphatidylinositol
- the efficacy of other clinically used anti-neoplastic pyrimidine nucleosides is limited by kinase activity. Since the release of ara-CMP from ara-CDP-DL-dipalmitin during phosphatidyl ⁇ inositol synthesis is independent of kinase activity, adminis ⁇ tration of ara-C and analogous compounds in the form of phospholipid prodrugs is expected to enhance antitumor activity, and lower toxicity.
- the nucleotides ara-C, ara-A and TTJ are known chemotherapeutic agents for treatment of various types of cancer.
- CDP-DG The chemical synthesis of CDP-DG in low yields was first described by Paulus, H. and Kennedy, E.P., J. Biol. Chem. 235, 1303 (1960) , and later by Agranoff and Suomi, Biochem. Prep. .10, 47-51 (1963) .
- CMP-morpholidate condensed cytidine- ⁇ '-monophosphate-morpholidate
- DL-diacylglycerol phosphate DL-diacylglycerol phosphate
- racemic 1-0- hexadecyl-2-0-palmitoylglycero-3-phosphate morpholidate with ara-CMP was allowed to proceed for seven days, and the yield of the desired racemic l-0-hexadecyl-2-0-palmitoylglycero-3- phosphate was reported to be 30%.
- nucleoside diphosphate diglycerides is modified such that instead of reacting a nucleoside-5'-monophosphate morpholidate with a phosphatidic acid derivative, first the phosphatidic acid derivative is converted into a corresponding amidate, for example morpholidate, which is then reacted with the free acid or salt form of the desired nucleoside-5'-monophosphate, the yields are substantially increased, and the reaction time is significantly shorter.
- a idates other phosphatidic acid derivatives in which one of the phosphate hydroxyls is replaced by a leaving group, may also be employed with similar results.
- nucleoside diphosphate diglycerides were synthesized by the improved methods of the present invention, the reaction time was reduced from several days to 3 to 10 hours, and the yield was increased to about 60 to 80%. Furthermore, the purification of the nucleoside diphosphate diglycerides is highly facilitated. When synthesizing the target compounds by the new route, phosphatidic acid is almost completely absent in the reaction mixture, which greatly simplifies and speeds up purification of the desired product. Crude reaction mixtures can easily be purified in a single HPLC procedure, resulting in faster elution, and higher yields of pure compound.
- the improved results are not limited to nucleoside diphosphate diglyceride synthesis; the synthesis route according to the present invention is generally applicable to the preparation of monoglyceride diphosphate, diglyceride diphosphate and and corresponding triphosphate derivatives of various compounds, such as nucleosides, phosphonoformates, and nucleoside phosphonoformates and analogues thereof.

- nucleoside as used throughout the specification and claims includes naturally occurring nucleosides and their analogues.
- the naturally occurring nucleoside are those nucleoside species comprising a pyrimidine or purine base e.g., adenine, guanine, cytosine, uracil, inosine, or thymine, linked to a ribose (ribonucleoside) or 2•-deoxyribose (deoxyribonucleoside) 5-carbon cyclic sugar group.
- Ribonucleosides and deoxynucleosides are phosphorylated at the 5' site and enzymatically assembled into RNA and DNA respectively in vivo.
- Nucleoside analogues may comprise a naturally occurring purine or pyrimidine base attached to an analogue of the naturally occurring ribose group, an analogue of a purine or pyrimidine base attached to a ribose or 2'-deoxyribose group which is present in naturally occurring nucleosides, or alternatively, both the base and the ribose moieties of the nucleoside analogues may be different from the moieties found in nature.
- a nucleoside analogue may also comprise either a naturally occurring base or a base analogue attached to a nonribose sugar moiety.
- Analogs of both the purine or pyrimidine base and the ribose group can differ from a corresponding naturally occurring moiety by having new substituent groups attached thereto, by having naturally occurring substituent groups deleted therefrom, or by having atoms normally present replaced by others.
- Naturally occurring nucleosides have a purine or pyrimidine base attached to ribose or a ribose residue through the nitrogen in the 9 position of the purines and through the nitrogen in the 1 position of the pyrimidines. These nitrogens are linked by a ⁇ -N-glycosyl linkage to the 1* carbon of the pentose residue.
- Nucleoside analogues may comprise a purine or pyrimidine base attached to the pentose moiety in a non-naturally occurring linkage such as, for example, through the nitrogen at the 3 position rather than the 1 position of pyrimidine.
- Nucleoside analogues are believed to have cytotoxic or antiviral effects because they inhibit DNA or RNA synthesis in the proliferation of tumor cells or in the process of viral replication. Specific classes of nucleoside analogues found to have these effects are as follows:
- Dideoxynucleosides wherein the hydroxyl groups at both the 2' and 3'-position of ribose are replaced by hydrogen for example, 2' ,3 *-dideoxycytidine (ddc) ; 2' ,3'-dideoxyinosine (ddl) ; 2' ,3 •-dideoxyadenosine (ddA) ; 3'-deoxythymidine (3dT) ; and 2' ,3'-dideoxyguanosine (ddG) ; .
- Dideoxynucleosides are particularly useful in treating retroviral infections such as AIDS, hairy cell leukemia, topical spastic paraparesis and hepatitis B, where viral replication requires the transcription of viral RNA into DNA by viral reverse transcriptase.
- Acyclic nucleosides wherein the acyclic pentose residue is a fragment of a cyclic pentose, such as an hydroxylated 2-propoxymethyl residue or an hydroxylated ethoxymethyl residue.
- Particular nucleoside residues having these structures include 2-amino-l,9-dihydro-9-[ (2-hydroxy- ethoxy)methyl]-6H-purine-6-one (acyclovir) or ganciclovir (DHPG) , pencyclovir and famcyclovir.
- the phosphate groups are generally connected to the 5' carbon of the pentoses in the nucleoside monophosphate reactants in the methods of the present invention, it is important to recognize that in analogues having pentose residues that are not complete pentoses, the phosphate groups are connected to the carbon that would have been the 5' carbon if the pentose were complete. In these pentose fragments, the 2' and/or 3' carbons may be missing; nevertheless, they are considered to be nucleoside derivatives within the meaning of present invention, and the carbon atom to which the phosphate groups are connected will be referred to herein as the 5' carbon for purposes of consistency of usage.

- suitable amidates include, but are not limited to, imid- azolidate, anisidate, piperidate and l,l'-carbonyl- diimidazole.
- the phospholipid amidates of the present invention (Formula I) are new compounds, and can be prepared by reacting a corresponding phospholipid, in free acid or salt form, with a suitable amine. The preparation of phosphatidic acid morpholidate is illustrated in the Examples hereinafter.
- the basic catalyst used in the process of the present invention serves to convert the hydroxyl of the phosphate group to O " , and may, for example, be pyridine or 4'- dimethylaminopyridine. 2. Description of Preferred Embodiments
- nucleoside diphosphate or triphosphate diglycerides are prepared by reacting corresponding phosphatidic acid morpholidates with nucleoside-5'-monophosphates or -5'- diphosphates in anhydrous pyridine.
- the phosphatidic acid morpholidates may be prepared and further reacted in a salt form, for example in the form of 4'-morpholine-N,N'- dicyclohexylcarboxamidinium salt, as shown hereinbelow, in the Example.
- the target nucleoside di- or triphosphate diglycerides can be obtained in the form of their salts, for example, as metal salts, by means of treatment with a base, preferably an inorganic base, as known to those in the art.
- Phosphatidic acid morpholidates may be prepared from "free" phosphatidic acids and morpholine, preferably in a solvent mixture of chloroform and tert-butanol.
- the resultant phosphatidic acid morpholidate is lyophilized. Thereafter, the lyophilized morpholidate and the corresponding nucleoside- 5'-monophosphate are dissolved in anhydrous pyridine, and the reaction is allowed to proceed at room temperature.
- the molar ratio of phosphatidic acid morpholidate and nucleoside-5'- monophosphate typically is between about 2:1 and 1:2, preferably between about 2:1 and 1:1.
- the progress of the reaction can be monitored by thin layer chromatography (TLC) .
- the speed of the reaction varies depending on the actual reactants. In some instances optimum conversions is reached in less than an hour. Generally, the reaction is complete within about 5 to 10 hours. The yields typically are between about 60% and about 80%.
- the obtained nucleoside di- and triphosphate diglycerides are essentially free of phosphatidic acid, which highly simplifies and speeds up their purification. Crude reaction mixtures can easily be purified in a single HPLC procedure, resulting in larger amounts of pure product and faster elution.
- phosphatidic acid morpholidates may also be synthesized directly from the disodium salt of phosphatidic acid, without prior conversion to the free acid form. This is done under the same reaction conditions as hereinabove described, except that small amounts of methanol/water (1:1 v/v) are usually added to obtain a clear solution. The yields obtained by this variant of the process do not differ significantly from the yields obtained when using free phosphatidic acid as a starting compound. Also, the morpholidate prepared this way reacts equally well with the corresponding nucleoside-5'-mono- or diphosphate.
- nucleoside diphosphate diglycerides that can be prepared in accordance with the method of the present invention is encompassed by the following formula (II)
- R x and R 2 independently are hydroxyl or aliphatic groups having from 1 to 24 carbon atoms, and 0 to 6 sites of unsaturation;
- A is oxygen, sulfur, or methylene, k is 0 or 1; n is 0 or 1; and
- Nu is a nucleoside or nucleoside analogue.
- the method of the invention can be used to prepare glycerol, monoglyceride and diglyceride derivatives of naturally occurring nucleosides, for example, adenine diphosphate, and to prepare the naturally occurring intermediate of lipid metabolism, cytidine diphosphate diglyceride.
- the methods are also useful in preparing diglyceride diphosphate derivatives of cytotoxic and antiviral nucleoside analogues. Particularly preferred are within this group: (3'-azido-3* -deoxy) thymidine-5 ' -diphosphate- ( 1, 2- dilauroyl)glycerol (AZT-DP-DLG) ;
- diacylglycerol phosphate phosphonoacids are synthesized by preparing the morpholidate of the corresponding phosphatidic acid, and coupling to the corresponding phosphonoacid, which can be phosphonoformate or phosphonoacetate.
- the new synthesis is adapted for the preparation of diacylglycerol phosphate phosphonoacids to which nucleosides including those having a cytotoxic or antiviralactivity are coupled, for example, by a carboxyl ester linkage.
- Preferred phosphonoacid derivatives are 1,2-dilauroylglycero- 3-phosphate-(pyro)-phosphonoformate; or 1,2-dimyristoylglycero-3-phosphate-(pyro)-phosphonoformate.
- the chemical reactions described above are generally disclosed in terms of their broadest application to the methods of the invention. Occasionally, the reactions may not be applicable as described to the synthesis of each compound suggested within the disclosed scope. The compounds for which this occurs will be readily recognized by those skilled in the art. In all such cases, either the reactions can be successfully performed by conventional modifications known to those skilled in the art, e.g., by appropriate protection of interfering groups, by changing to alternative conventional reagents, or by routine modification of reaction conditions. In all preparative methods, all starting materials are known or readily preparable from known starting materials.
