Use of alkylphosphocholines in combination with antimetabolites for the treatment of benign and malignant oncoses in humans and mammals
View Patent ↗The invention relates to the use of alkylphosphocholines in combination with antimetabolites for the treatment of multiple myeloma, colon cancer or renal cancer. Preferred alkylphosphocholines are described by the Formula II. A particularly effective treatment includes administering a combination of perifosine and capecitabine.
1. A method of treating multiple myeloma, wherein the method comprises administering a therapeutically effective amount of an alkylphosphocholine compound having the structure of Formula II:
in which, independently of one another:
m, n, p, z are a whole number between 0 and 4;
X is O;
R is H, a straight-chain or branched (C 1 -C 17 )-alkyl group which may be saturated or unsaturated with one or two double and/or triple bonds;
R 1 , R 2 are, independently of one another, H or a straight-chain or branched (C 1 -C 6 )-alkyl group, preferably methyl and ethyl, a (C 3 -C 7 )-cycloalkyl group,
wherein said alkylphosphocholine is administered before and/or during treatment with at least one antimetabolite selected from the group consisting of 5-Azacytidine, 2-Mercaptopurine, 5-fluorouracil, 6-Thioguanine, Capecitabine, Cladribine, Clofarabine, Cytarabine, Decitabine, Doxifluridine, Floxuridine, Fludarabine, Forodesine, Gemcitabine, Nelarabine, Pentostatin, Sapacitabine, Thiarabine and Troxacitabine.
2. The method according to claim 1 , wherein said alkylphosphocholine is octadecyl 1,1-dimethylpiperidinium-4-yl phosphate (perifosine).
3. The method according to claim 1 , wherein said method comprises administering a pharmaceutical composition comprising a therapeutically effective amount of an alkylphosphocholine compound of the general Formula II, customary pharmaceutical carriers, excipients and/or diluents, and wherein said composition is administered before and/or during the treatment with at least one antimetabolite.
4. The method according to claim 1 , wherein said alkylphosphocholine is administered before and/or during treatment with two or more antimetabolites.
5. The method according to claim 1 , wherein said alkylphosphocholine is octadecyl 1,1-dimethylpiperidinium-4-yl phosphate (perifosine) and said antimetabolite is capecitabine.
6. A method of treating colon cancer, wherein the method comprises administering a therapeutically effective amount of an alkylphosphocholine compound having the structure of Formula II:
in which, independently of one another:
m, n, p, z are a whole number between 0 and 4;
X is O;
R is H, a straight-chain or branched (C1-C17)-alkyl group which may be saturated or unsaturated with one or two double and/or triple bonds;
R1, R2 are, independently of one another, H or a straight-chain or branched (C1-C6)-alkyl group, preferably methyl and ethyl, a (C3-C7)-cycloalkyl group,
wherein said alkylphosphocholine is administered before and/or during treatment with at least one antimetabolite selected from the group consisting of 5-Azacytidine, 2-Mercaptopurine, 5-fluorouracil, 6-Thioguanine, Cladribine, Clofarabine, Cytarabine, Decitabine, Doxifluridine, Floxuridine, Fludarabine, Forodesine, Gemcitabine, Nelarabine, Pentostatin, Sapacitabine, Thiarabine and Troxacitabine.
7. The method according to claim 6 , wherein said alkylphosphocholine is octadecyl 1,1-dimethylpiperidinium-4-yl phosphate (perifosine).
8. The method according to claim 6 , wherein said method comprises administering a pharmaceutical composition comprising a therapeutically effective amount of an alkylphosphocholine compound of the general Formula II, customary pharmaceutical carriers, excipients and/or diluents, and wherein said composition is administered before and/or during the treatment with at least one antimetabolite.
9. The method according to claim 6 , wherein said alkylphosphocholine is administered before and/or during treatment with two or more antimetabolites.
