Method of using adenosine receptor blockers during tissue ablation
A mammal undergoing an ablation procedure is treated for symptoms associated with adenosine by administering one or more adenosine receptor antagonists to the mammal prior to or during the procedure.
1. A method for promoting blocking of an adenosine receptor in a mammalian subject undergoing an energy-based ablation procedure by administering adenosine receptor antagonists selected from 8SPT, MRS1754, MRS1220, MRE3008F20, MRS1523, ATL146e, or combinations thereof to the mammalian subject.
2. A method according to claim 1 , wherein in vivo, the agent binds to one or more adenosine receptors.
3. A method according to claim 1 , wherein the agent is administered in a pharmaceutical composition that includes a pharmaceutically acceptable carrier or diluent.
4. A method according to claim 1 , wherein the mammalian subject is human.
5. A method according to claim 1 , wherein the adenosine receptor antagonists is one or more A1 adenosine receptor antagonists.
6. A method according to claim 5 , wherein the A1 adenosine receptor antagonists is selected from the group consisting of 1,3-dipropyl-8-cyclopentylxanthine, 8-(4-[({[(2-aminoethyl)amino]carbonyl)oxy]-phenyl}-1,3-dipropylxanthine, N(6)-Endonorbornan-2-yl-9-methyladenine, ((S)-(−)-8-(3-Oxocyclopentyl)-1,3-dipropyl-7H-purine-2,6-dione), (3-[(4-amino)phenethyl]-8-cyclopentylexanthine, 1,3-dipropyl-8-(dicyclopropylmethyl)xanthine, and combinations thereof.
7. A method according to claim 1 , wherein the adenosine receptor antagonist is one or more A2 adenosine receptor antagonists.
8. A method according to claim 7 , wherein the A2 adenosine receptor antagonists is selected from the group consisting of 1,3-diallyl-8-(3,4,5-trimethoxystyryl)-7-methylxanthine, 8-(3,4,5-trimethoxystyryl)-1,3,7-trimethylxanthine, 7-(2-phenylethyl)-5-amino-2-(2-furyl)-pyrazolo-[4,3-e]-1,2,4-triazolo[1,5- -c]pyrimidine, 4-(2-[7-amino-2-(2-furyl[1,2,4]-triazolo[2,3-a[1,3,5]triazin-5-yl-)phenol-), 8-(3-Chlorostyryl)caffeine, E)-1,3-dipropyl-7-methyl-8-(3,4-dimethoxystyryl)xanthine, enprofylline, 3-isobutyl-8-pyrrolidinoxanthine, [N-(4-cyanophenyl)-2-[4-(2,3,6,7-tetrahydro-2,6-dioxo-1,3-dipropyl-1H-pur-in-8-yl)-phenoxy]acetamide], and combinations thereof.
9. A method according to claim 1 , wherein the adenosine receptor antagonist is one or more A3 adenosine receptor antagonists.
10. A method according to claim 9 , wherein the agent is selected from the group consisting of 3,6-dichloro-2′-(isopropoxy)4′-methylflavone, 6-phenyl-1,4-dihydropyridines, 6-carboxy-methyl-5,9-dihydro-9-methyl-2-phenyl-[1,2,4]-triazolo[5,1-a][2,-7]naphthyridine, (3-(4-methoxyphenyl)-5-amino-7-oxo-thiazolo[3,2]pyrimidine), 9-chloro-2-(2-furanyl)[1,2,4]triazolo[1,5-c]quinazolin-5-amine, (2-(4-bromophenyl)-7,8-dihydro-4-propyl-1H-imidazo[2,1-i]purin-5(4H)-one dihydrochloride), and combinations thereof.
11. A method according to claim 1 , wherein the ablation procedure is radiofrequency of a cancer tumor.
