Tetrapropylammonium tetrathiomolybdate and related compounds for anti-angiogenic therapies
View Patent ↗Disclosed are copper-binding compounds with improved properties and methods of using such compounds in the prevention and treatment of angiogenic diseases, such as cancer. Advantages of the invention include the enhanced stability of the compounds, which is achieved without reduction in efficacy. Pharmaceutical compositions, therapeutic kits and combination treatment methods and uses are also provided.
1. A composition comprising a therapeutically effective amount of tetrapropylammonium tetrathiomolybdate and a pharmaceutically acceptable excipient, said amount effective to treat an angiogenic disorder, the composition further comprising a therapeutic agent different from said tetraalkylammonium tetrathiomolybdate compound.
2. The composition of claim 1 , further comprising a zinc compound.
3. The composition of claim 1 , wherein the therapeutic agent is an anti-angiogenic agent.
4. The composition of claim 3 , wherein the anti-angiogenic agent is selected from the group consisting of angiostatin, endostatin, trientine, penicillamine, and zinc.
5. The composition of claim 1 , wherein the therapeutic agent is an anti-cancer agent.
6. The composition of claim 5 , wherein the anti-cancer agent is selected from the group consisting of a chemotherapeutic agent, radiotherapeutic agent, immunotoxin, anti-angiogenic agent, apoptosis-inducing agent, a distinct agent that binds copper, and a zinc compound.
7. The composition of claim 1 , which is in a tablet or time release capsule.
8. A kit comprising, in at least one container, a therapeutically effective amount of at least one tetraalkylammonium tetrathiomolybdate compound and: (a) a therapeutically effective amount of at least one therapeutic agent that is different from said tetraalkylammonium tetrathiomolybdate compound, said therapeutic agent selected from the group consisting of an anti-cancer agent and an anti-angiogenic agent; or (b) at least one component of an ceruloplasmin oxidase assay system for determining serum ceruloplasmin levels.
9. The kit of claim 8 , wherein said at least one tetraalkylammonium tetrathiomolybdate compound is disposed in a pharmaceutically acceptable composition.
10. The kit of claim 8 , wherein said at least one tetraalkylammonium tetrathiomolybdate compound is tetrapropylammonium tetrathiomolybdate.
11. The kit of claim 8 , wherein said kit comprises said at least one tetraalkylammonium tetrathiomolybdate compound and said therapeutic agent.
12. The kit of claim 11 , wherein said therapeutic agent is a zinc compound or an anti-angiogenic agent.
13. The kit of claim 11 , wherein said therapeutic agent is an anti-cancer agent.
14. The kit of claim 11 , wherein said at least one tetraalkylammonium tetrathiomolybdate compound and said therapeutic agent are comprised within a single container.
15. The kit of claim 11 , wherein said at least one tetraalkylammonium tetrathiomolybdate compound and said therapeutic agent are comprised within distinct containers.
16. The kit of claim 8 , wherein said kit comprises said at least one tetraalkylammonium tetrathiomolybdate compound and said component of an assay system for determining serum ceruloplasmin levels.
17. The kit of claim 16 , wherein said kit further comprises all components of an assay system for determining serum ceruloplasmin levels.
