Methods and devices for using isoperillyl alcohol
The present invention provides for a method of treating a disease such as cancer, comprising the step of administering to a patient a therapeutically effective amount of an isomer or analog of monoterpene or sesquiterpene (or its derivative), such as an isoperillyl alcohol. The present invention also provides for a method of treating a disease comprising the step of administering to a patient a therapeutically effective amount of a derivative of an isomer or analog of monoterpene or sesquiterpene, such as an isoperillyl alcohol carbamate. The derivative may be an isoperillyl alcohol conjugated with a therapeutic agent such as a chemotherapeutic agent. The route of administration may vary, including inhalation, intranasal, oral, transdermal, intravenous, subcutaneous or intramuscular injection.
1. A method for killing malignant glioma cells, comprising treating the malignant glioma cells with an amount of (4-isopropylidene cyclohex-1-enyl)methanol, wherein the amount of (4-isopropylidene c clohex-1-eny l)methanol is less than the amount of perillyl alcohol needed to achieve the same level of killing.
2. The method of claim 1 , wherein at the amount of (4-isopropylidene cyclohex-1-enyl)methanol used, the percentage of surviving glioma cells is at least 10% lower than the percentage of surviving glioma cells treated b the same amount of perillyl alcohol.
3. The method of claim 2 , wherein at the amount of (4-isopropylidene cyclohex-1-enyl)methanol used, the percentage of surviving glioma cells is at least 20% lower than the percentage of surviving glioma cells treated by the same amount of perillyl alcohol.
4. The method of claim 1 , wherein the glioma cells are glioblastoma cells.
5. The method of claim 1 , wherein at the amount of (4-isopropylidene cyclohex-1-enyl)methanol used, the percentage of surviving glioma cells is at least 30% lower than the percentage of surviving glioma cells treated by the same amount of perillyl alcohol.
6. The method of claim 5 , wherein at the amount of (4-isopropylidene cyclohex-1-enyl)methanol used, the percentage of surviving glioma cells is at least 40% lower than the percentage of surviving glioma cells treated by the same amount of perillyl alcohol.
7. The method of claim 1 , wherein at the amount of (4-isopropylidene cyclohex-1-enyl)methanol used, the percentage of surviving glioma cells is at least 50% lower than the percentage of surviving glioma cells treated by the same amount of perillyl alcohol.
8. A method for killing malignant glioma cells in a mammal, comprising the step of administering to the mammal of an amount of (4-isopropylidene cyclohex-1-enyl)methanol using a nasal delivery device, wherein the amount of (4-isopropylidene cyclohex-1-enyl)methanol is less than the amount of perillyl alcohol needed to achieve the same level of killing.
9. The method of claim 8 , wherein the nasal delivery device is selected from the group consisting of an intranasal inhaler, an intranasal spray device, an atomizer, a nebulizer, a metered dose inhaler (MDI), a pressurized dose inhaler, an insufflator, a unit dose container, a pump, a dropper, a squeeze bottle and a bi-directional device.
