7-aminocephalosporanic acid derivative as inhibitor of IL15 and IL-2 activity
The invention relates to a 7-aminocephalosporanic acid derivative, Cefazolin, for use as an inhibitor of IL-15 and IL-2 receptors in the prevention and treatment of diseases related to IL-15 and IL-2 overproduction.
1. A method of treating psoriasis in a patient comprising:
(1) a step of identifying a patient having elevated levels of one or more selected from the group consisting of IL-2, IL-15, IL-17, and TNF-α; and
(2) a step of treating the patient by administering to the patient in need thereof a therapeutically effective dose Cefazolin or pharmaceutically acceptable salts thereof or pharmaceutically acceptable composition thereof wherein the pharmaceutically acceptable compositions comprise a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof and a pharmaceutically acceptable excipient, carrier or diluent.
2. The method according to claim 1 , wherein the pharmaceutically acceptable compositions are administered intravenously or intramuscularly.
3. The method of claim 1 wherein the therapeutically effective dose of Cefazolin administered is sufficient to provide a serum concentration between 20 μm and 300 μm.
4. The method of claim 1 wherein the therapeutically effective dose of Cefazolin initially administered is between 250 and 500 mg followed by administration of a therapeutically effective dose between 250 and 500 mg of Cefazolin after an interval of between 8 to 12 hours.
5. The method of claim 1 , wherein the method comprises either:
i) administering to the patient in need thereof the therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient, or
ii) administering to the patient in need thereof the pharmaceutically acceptable composition, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient.
6. A method of reducing the amount of IL-15 and/or IL-2 in a patient having psoriasis comprising:
(1) a step of identifying a patient having elevated levels of one or more selected from the group consisting of IL-2 and IL-15: and
(2) a step of treating the patient by administering to the patient in need thereof a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof or pharmaceutically acceptable compositions thereof wherein the pharmaceutically acceptable compositions comprise a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof and a pharmaceutically acceptable excipient, carrier or diluent.
7. The method of claim 6 wherein the therapeutically effective dose of Cefazolin is administered intravenously or intramuscularly.
8. The method of claim 6 wherein the therapeutically effective dose of Cefazolin administered is sufficient to provide a serum concentration between 20 μM and 300 μM.
9. The method of claim 6 , wherein the method comprises either:
i) administering to the patient in need thereof the therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient, or
ii) administering to the patient in need thereof the pharmaceutically acceptable composition, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient.
10. A method for reducing synthesis of TNF-α and/or IL-17 in a patient having psoriasis comprising:
(1) a step of identifying a patient having elevated levels of one or more selected from the group consisting of IL-17 and TNF-α; and
(2) a step of treating the patient by parenterally administering to the patient in need thereof a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof or pharmaceutically acceptable compositions thereof wherein the pharmaceutically acceptable compositions comprise a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof and a pharmaceutically acceptable excipient, carrier or diluent.
11. The method of claim 10 , wherein the method comprises either:
i) administering to the patient in need thereof the therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient, or
ii) administering to the patient in need thereof the pharmaceutically acceptable composition, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient.
12. A method for preventing overproduction of IL-15 and/or IL-2 in a patient having psoriasis comprising:
(1) a step of identifying a patient having psoriasis associated with overproduction of one or more selected from the group consisting of IL-2 and IL-15; and
(2) a step of treating the patient by administering to the patient in need thereof a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof or pharmaceutically acceptable compositions thereof wherein the pharmaceutically acceptable compositions comprise a therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof and a pharmaceutically acceptable excipient, carrier or diluent.
13. The method of claim 12 , wherein the method comprises either:
i) administering to the patient in need thereof the therapeutically effective dose of Cefazolin or pharmaceutically acceptable salts thereof, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient, or
ii) administering to the patient in need thereof the pharmaceutically acceptable composition, wherein the Cefazolin or pharmaceutically acceptable salts thereof is the sole active ingredient.
