Summary for Patent: 6,121,245
Title: Method of treating cancer using alkylglycerols in conjunction with chemotherapy
Abstract:Tumor cell kill is increased and the sensitivity of tumors to chemotherapeutic agents is increased by the administration of an alkylglycerol together with the chemotherapeutic agent.
Inventor(s): Firshein; Richard N. (New York, NY)
Assignee:
Application Number:08/791,757
Patent Claims:1. A method of treating a malignant tumor comprising of malignant tumor cells sensitive to the combination below in a subject, which comprises administering to the subject a combination consisting essentially of:

a chemotherapeutic agent; and

a shark liver oil,

wherein the combination is more effective to kill malignant tumor cells or inhibit malignant tumor cell proliferation than the chemotherapeutic agent alone.

2. The method of claim 1, wherein the subject is a human.

3. The method of claim 1, wherein the chemotherapeutic agent is doxorubicin.

4. The method of claim 1, wherein the administration of the chemotherapeutic agent follows administration of the shark liver oil.

5. The method of claim 1, wherein the chemotherapeutic agent is administered concurrently with the shark liver oil.

6. The method of claim 1, wherein the tumor is infiltrating duct carcinoma, adenocarcinoma or colon cancer.

7. The method of claim 1, wherein the effective amount of the shark liver oil is from about 1 g/Kg of body weight to 10 g/Kg of body weight.

8. The method of claim 1, wherein the effective amount of the shark liver oil is about 300 mg per day.

9. The method of claim 1, wherein the chemotherapeutic agent is an alkylating agent.

10. The method of claim 9, wherein the alkylating agent is selected from the group consisting of chloromethine, chlorambucil, melphalan, uramustine, mannomustine, extramustine phosphate, mechlor-thaminoxide, cyclophosphamide, ifosamide, trifosfamide, tretamine, thiotepa, triaziquone, mitomycin, busulfan, piposulfan, carmustine, lomustine, semustine, streptozotocine, alkylating agents of the mitobronitole, dacarbazine, cisplatin and carboplatin.

11. The method of claim 1, wherein the chemotherapeutic agent is an antimetabolite.

12. The method of claim 11, wherein the antimotabolite is selected from the group consisting of methotrexate, aminopterin, 3'-dichloromethotrexate, 5-fluorouracil, floxuridine, tegafur, cytarabine, idoxuridine, flucytosine; mercaptopurine, thioguanine, azathioprine, tiamiprine, vidarabine, pentostatin and puromycin.

13. The method of claim 1, wherein the chemotherapeutic agent is a natural product.

14. The method of claim 13, wherein the natural product is selected from the group consisting of vinca alkaloids, vinblastine, vincristine, epipodophylotoxins, etoposide, teniposide, adrimycin, daunomycin, dactinomycin, daunorubicin, doxorubicin, mithramycin, bleomycin, mitomycin, L-asparaginase, alphainterferon, camptothecin, taxol, retinoids and retinoic acid.
