Abstract: T cell lymphoma is treated by administering to a patient suffering from T cell lymphoma a therapeutically effective amount of 10-propargyl-10-deazaaminopterin. Remission is observed in human patients, even with drug resistant T cell lymphoma at weekly dosages levels as low as 30 mg/m2. In general, the 10-propargyl-10-deazaaminopterin is administered in an amount of from 30 to 275 mg/m2 per dose.

Abstract: Sensitivity of a patient's cancer to treatment with 10-propargyl-10-deazaaminopterin is assessed and patients are selected for treatment of cancer with 10-propargyl-10-deazaaminopterin, by determining the amount of a selected polypeptide expressed by the cancer and comparing the amount with the amount of the selected polypeptide expressed by a reference cancer. The polypeptide includes a member of a folate pathway polypeptide within a cell and may include at least one of reduced folate carrier-1 enzyme (RFC-1), dihydrofolate reductase (DHFR), folylpoly-gamma-glutamate synthetase (FPGS), thymidylate synthase (TS), ?-glutamyl hydrolase (GGH), and glycinamide ribonucleotide formyltransferase (GARFT).

Abstract: The present invention relates to a method for assessing the sensitivity of a patient's cancer to treatment with 10-propargyl-10-deazaminopterin and a method for selecting a patient for treatment of cancer with 10-propargyl-10-deazaminopterin, by determining the amount of a selected polypeptide expressed by the cancer and comparing the amount with the amount of the selected polypeptide expressed by a reference cancer, wherein the polypeptide includes a member of folate pathways within cells and may include at least one of reduced folate carrier-1 enzyme (RFC-1), dihydrofolate reductase (DHFR), folylpoly-gamma-glutamate synthetase (FPGS), thymidylate synthase (TS), ?-glutamyl hydrolase (GGH), and glycinamide ribonucleotide formyltransferase (GARFT). The present invention also relates to the use of 10-propargyl-10-deazaminopterin in the treatment of multiple myeloma.

Abstract: Preliminary clinical studies in humans have now been done which show both the efficacy of 10-propargyl-10dAM and a preferred dosage schedule for such treatments. In addition, it has now been determined that combinations of 10-propargyl-10-deazaaminopterin (preferably highly purified forms, substantially free of 10-deazaaminopterin) with taxols exhibit synergistic effectiveness in the treatment of tumors. 10-propargyl-10-deazaaminopterin and a taxol in therapeutically effective amounts can be administered concurrently, one right after the other, or with a period of time in between.

Abstract: Highly purified 10-propargyl-10-deazaaminopterin (10-propargyl-10dAM) compositions tested in xenograft models for their efficacy against human tumors are shown to be far superior to methotrexate ("MTX") and are even superior to the newer clinical candidate edatrexate ("EDX"). Moreover, 10-propragyl-10dAM showed a surprising ability to cure tumors such that there was no evidence of tumor growth several weeks after the cessation of therapy. Thus, highly purified compositions containing 10-propargyl-10dAM can be used to treat human tumors, particularly human mammary tumors and human lung cancer.

Abstract: Pharmaceutical compositions for the modulation of the immune reaction of warm blooded animals that are derivatives of the 2-oxindole-3-acetic acid or the 2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid are described, and whereby the derivatives can optionally be in an equilibrium with each other.The derivatives included in the pharmaceutical compositions comprise those compounds which are already described in the literature and also new compounds.Furthermore, new derivatives of the the 2-oxindole-3-acetic acid and the 2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid are described, particularly also the the pure antipodes of the mixture of enantiomeres of the 2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid.

Abstract: What are described are new glucosides and their sugar-free decomposition products, as well as synthetically produced derivatives, which can be used as active components of pharmaceutical compositions. The novel glucosides have been isolated from aqueous extracts of vegetable pollen. These novel glucosides, sugar-free decomposition products and their derivatives have the effectiveness to modulate the immune system of warm blooded animals and they can be used as active components in pharmaceutical compositions for the treatment of tumors and virus-related diseases.
