Therapeutics for cancer using 3-bromopyruvate and other selective inhibitors of ATP production
The present invention relates to methods of treating a cancerous tumor using selective inhibitors of ATP production. The present invention also relates to pharmaceutical preparations comprising such inhibitors and methods for administering them intraarterially directly to a tumor, as well as methods for identifying compositions that selectively inhibitor ATP production for use in the invention.
1. A method of treating primary or secondary liver cancer in a subject comprising administering to a subject having a primary or secondary liver tumor an effective amount of a 3-halopyruvate or a salt thereof delivered by transcatheter hepatic intraarterial injection into the liver.
2. The method of claim 1 , wherein the 3-halopyruvate is 3-bromopyruvate.
3. A method of treating primary or secondary liver cancer in a subject comprising administering to a subject having a primary or secondary liver tumor a therapeutically effective amount of a 3-halopyruvate or a salt thereof and fluorouracil delivered by transcatheter hepatic intraarterial injection into the liver.
4. The method of claim 1 , wherein the 3-halopyruvate or salt thereof is provided in a sustained-release formulation.
5. The method of claim 3 , wherein the 3-halopyruvate is 3-bromopyruvate.
6. A method of treating primary or secondary liver cancer in a subject comprising administering to a subject having a primary or secondary liver tumor delivered by transcatheter hepatic intraarterial injection into the liver an effective amount of a compound represented by formula:
wherein, independently of each occurrence:
X represents a halide;
R 1 represents OR, H, N(R″)2, C1-C6 alkyl, C6-C12 aryl, C1-C6 heteroalkyl, or C6-C12 heteroaryl;
R″ represents H, C1-C6 alkyl, or C6-C12 aryl;
R represents H, alkali metal, C1-C6 alkyl, C6-C12 aryl or C(O)R′; and
R′ represents H, C1-C20 alkyl or C6-C12 aryl, or a salt thereof.
7. The method of claim 6 , wherein the halide is bromide.
8. A method of treating primary or secondary liver cancer in a subject comprising administering to a subject having a primary or secondary liver tumor delivered by transcatheter hepatic intraarterial injection into the liver an effective amount of a compound represented by formula:
wherein, independently of each occurrence:
X represents a halide;
R 1 represents OR, H, N(R″)2, C1-C6 alkyl, C6-C12 aryl, C1-C6 heteroalkyl, or C6-C12 heteroaryl;
R″ represents H, C1-C6 alkyl, or C6-C12 aryl;
R represents H, alkali metal, C1-C6 alkyl, C6-C12 aryl or C(O)R′; and
R′ represents H, C1-C20 alkyl or C6-C12 aryl, or a salt thereof and administering fluorouracil to said subject.
9. The method of claim 8 , wherein the halide is bromide.
10. A method of treating a liver tumor that has metastasized within the liver of a subject an effective amount of a 3-halopyruvate or a salt thereof delivered by transcatheter hepatic intraarterial injection into the liver.
11. The method of claim 10 , wherein the 3-halopyruvate is 3-bromopyruvate.
12. The method of claim 1 , wherein the 3-halopyruvate is administered directly to the blood supply of the tumor without embolization of the tumor.
13. The method of claim 1 , consisting of administering to a subject having a liver tumor an effective amount of a 3-halopyruvate or a salt thereof delivered by transcatheter hepatic intraarterial injection into the liver.
