Methods of decreasing or preventing pain using spicamycin derivatives
View Patent ↗Methods of providing pain relief by administering a water-soluble derivative of spicamycin. Methods of using pain mediation agents are also provided.
1. A method of providing pain relief, the method comprising
identifying a subject in need of pain relief; and
administering to the subject an amount of a compound of Formula II, or a salt thereof, effective to provide significant pain relief in the subject,
wherein R 1 and R 2 are different from each other and represent —H or —OH, and R is —COCH 2 NH 2 ;
wherein the compound of Formula II is administered in a combination formulation comprising the compound of Formula II and a second analgesic or drug.
2. The method of claim 1 , wherein the second analgesic or drug is an anti-inflammatory agent.
3. The method of claim 1 , wherein R 1 is —H and R 2 is —OH.
4. The method of claim 1 , wherein R 1 is —OH and R 2 is —H.
5. The method of claim 1 , wherein the pain is neuropathic pain.
6. The method of claim 5 wherein the pain is postherpetic neuralgia, phantom or amputation stump pain, diabetic neuropathy, acquired immune deficiency syndrome neuropathy, back pain, visceral pain, or chronic pancreatitic neuropathy.
7. The method of claim 1 , wherein the pain is opioid-resistant.
8. The method of claim 1 , wherein the subject is a mammal.
9. The method of claim 1 , wherein the subject is a human.
10. The method of claim 1 , wherein the compound of Formula II is administered systemically.
11. The method of claim 1 , wherein the compound of Formula II is administered at a site of pain in the subject.
12. The method of claim 1 , wherein the compound of Formula II is administered via an implant.
13. The method of claim 12 , wherein the implant provides slow release of the compound of Formula II.
14. The method of claim 1 , wherein the compound of Formula II is administered intravenously.
15. The method of claim 1 , wherein the amount administered is about 1 ng to 4 mg/m 2 body surface area.
16. The method of claim 1 , wherein the amount administered is about 80 ng to 1 mg/m 2 patient body surface area.
17. The method of claim 1 , wherein the amount administered is about 10 to 100 mg/kg body weight.
18. The method of claim 17 , wherein the amount administered is about 100 mg/kg body weight.
19. The method of claim 1 , wherein the compound of Formula II is administered in an aqueous solution.
20. The method of claim 1 , wherein neuropathic pain is selectively relieved over nociceptive pain.
