Synthetic lactone formulations and method of use
View Patent ↗Natural and synthetic compounds having a lactone structure methods for alleviation of pain, especially pain associated with disorders such as melanoma, leukemia, breast cancer, lung cancer, ovarian cancer, colon cancer, esophagus cancer, liver cancer, and lymphatic cancer. Initial studies have shown that patients can be taken off of morphine when the preferred alpha-methylene-gamma-butyrolactone is administered in a dosage of between 60 and 120 mg/day intramuscularly.
1. A method of treating pain in a patient having a proliferation disorder comprising administering to an animal an effective amount of a composition comprising a compound or a pharmaceutically acceptable salt in a pharmaceutically acceptable carrier, to alleviate pain associated with cancer, wherein the compound has the following structure:
wherein R 1 -R 6 taken independently are a hydrogen atom or a group or grouping selected from the group consisting of alkyl, substituted alkyl, ally, substituted allyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, phenyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, halo, hydroxyl, alkoxy, substituted alkoxy, alkoxy, phenoxy, substituted phenoxy, aroxy, substituted aroxy, alkylthio, substituted alkylthio, phenylthio, substituted phenylthio, arylthio, substituted arylthio, cyano, isocyano, substituted isocyano, carbonyl, substituted carbonyl, carboxyl, substituted carboxyl, amino, substituted amino, amido, substituted amido, sulfonyl, substituted sulfonyl, sulfonic acid, phosphoryl, substituted phosphoryl, phosphonyl, substituted phosphonyl, polyaryl, substituted polyaryl, C1-C20 cyclic, substituted C1-C20 cyclic, heterocyclic, substituted heterocyclic, aminoacid, peptide, and polypeptide groups;
Z is a heteroatom selected from the group consisting of oxygen, sulfur, and nitrogen groupings in linear, branched, or cyclic structural formats; and
X is a heteroatom selected from the group consisting of oxygen, sulfur, and nitrogen groupings in linear, branched, or cyclic structural formats.
2. The method of claim 1 wherein the compound is α-methylene-γ-butyrolactone (Securolide).
3. The method of claim 1 wherein the proliferation disorder is a cancer selected from the group consisting of melanoma, leukemia, breast cancer, lung cancer, ovarian cancer, colon cancer, esophagus cancer, liver cancer, and lymphatic cancer.
4. The method of claim 1 wherein the dosage of the compound is equivalent to 60 to 120 mg/day given intramuscularly.
5. The method of claim 1 wherein the dosage is up to 400 mg/day.
6. The method of claim 1 wherein the compound is administered in an ointment or cream applied to the skin or mucosal surface.
7. The method of claim 1 wherein the compound is administered by injection.
8. The method of claim 7 wherein the compound is in an oil or cremophor based carrier.
9. The method of claim 1 wherein the compound is enteric coated for oral administration.
10. The method of claim 1 wherein the compound is in a syrup.
