The present invention relates to opioid and opioid-like compounds, and pharmaceutical formulations containing the same and methods of use thereof. Uses of the present invention include, but are not limited to, use for the prevention and treatment of septic shock and other disorders. The compounds described herein can be water soluble and can act through mechanisms mediated through pathways other than opiate receptors.
1. A method of treating conditions selected from the group consisting of, organ damage selected from the group consisting of liver, lung and kidney damage, rheumatoid arthritis, Crohn's disease, and multiple sclerosis, comprising administering to a subject in need thereof, a pharmaceutical composition comprising a therapeutically effective amount of a compound selected from the group consisting of dextromethorphan, 3-methoxy-morphinan and 3-hydroxy-morphinan, and enantiomers, diastereoisomers, and pharmaceutically acceptable salts thereof.
2. A method of treating conditions selected from the group consisting of, organ damage, selected from the group consisting of liver, lung and kidney damage, rheumatoid arthritis, Crohn's disease, and multiple sclerosis, comprising administering to a subject in need thereof, a pharmaceutical composition comprising a therapeutically effective amount of a compound of formula R-A-X:
wherein,
R is methyl, hydroxy or alkoxy,
A has the following structure:
and
X is methyl, cyclobutyl, n-propyl, CN, or enantiomers, diastereoisomers, or pharmaceutically acceptable salts thereof.
3. The method of claim 1 , wherein the pharmaceutical composition is administered orally in an amount selected from 2 to 100 mg per unit dose and one to four times a day.
4. The method of claim 1 , wherein the pharmaceutical composition is administered parenterally in an amount selected from 2 to 100 mg per unit dose and one to four times a day.
5. The method of claim 1 , wherein the organ damage is liver damage.
6. The method of claim 1 , wherein the organ damage is lung damage.
7. The method of claim 1 , wherein the organ damage is kidney damage.
8. A method of treating conditions selected from the group consisting of inflammation, and inflammatory liver, lung or kidney damage comprising administering to a subject in need thereof, a pharmaceutical composition comprising a therapeutically effective amount, from a daily dose of 2 to 100 mg, of a compound of the formula: RAX wherein X is selected from the group consisting of hydrogen and alkyl, A is
and R is selected from the group consisting of hydroxy, alkyl and alkoxy.
