摘要:
Novel heterocyclic compounds, which are represented by the following general formula, useful as anticancer drug potentiaters having a potentiating effect on the incorporation of anticancer drugs into cancer cells, the compounds each synthesized by, for example, reacting a epoxy compound obtained by reacting a heterocyclic compound with an epihalogenohydrin, with an amine derivative.

The present invention relates to an anthranilic acid derivative expressed by the following formula (1) or the following formula (2), or its pharmacologically permissible salt or solvate.
摘要:
Monoclonal antibodies are disclosed that may be produced by hybridomas obtained by fusing a mouse spleen cell immunized with an ADRIAMYCIN.RTM.-resistant human tumor cell and a mouse myeloma cell and which inhibit selectively the growth of cancer cells possessing pleiotropic drug resistance or enhance their sensitivity to said drug.
摘要:
The present invention provides a preventative/therapeutic agent for cancer capable of selectively and effectively killing cancer cells. A medicament of the present invention prepared by combining at least one selected from a substance that inhibits the activity of an enzyme belonging to the acyl-CoA synthase family and a substance that inhibits expression of a gene for an enzyme belonging to the acyl-CoA synthase family, with at least one selected from a substance that inhibits the activity of fatty acid synthase and a substance that inhibits expression of a fatty acid synthase gene and the like can be used as a preventative/therapeutic agent for cancer capable of selectively and effectively killing cancer cells.
摘要:
An agent for enhancing antitumor activity of antitumor agents comprising as the active ingredient diltiazem or a pharmaceutically acceptable acid addition salt thereof, an antitumor composition comprising the diltiazem or an acid addition salt thereof and a conventional antitumor agent, and further a method for treating tumors by administering diltiazem or an acid addition salt thereof together with a conventional antitumor agent in oral or parenteral route to patients suffering from various tumors. Said active diltiazem or a salt thereof is effective for enhancing the antitumor activity of antitumor agents because it can enhance sensitivity of tumor cells to antitumor agents regardless the tumor cells have resistance to the antitumor agents or not.
摘要:
A method of judging whether a patient is sensitive to imatinib or not, in case where the patient is suffering from a disease such as CML to be treated by administration of imatinib, that is, a method for judging whether the administration of imatinib is effective for the therapy of the disease or not, is disclosed. Amounts of a plurality of genes selected from the group consisting of the specific 77 genes in sample cells separated from body are measured; and the measured amounts are compared with those of responders and non-responders to imatinib or a derivative thereof or a pharmaceutically acceptable salt thereof:
摘要:

摘要:
The present inventors intended to search for substances that can regulate the expression of a molecular chaperone, GRP78, using the expression of GRP78 as an indicator. As a result, a novel tetronic acid derivative, versipelostatin compound (also known as JL68) shown in formula (I) having the activity of suppressing GRP78 expression was isolated from the metabolite of Streptomyces versipellis strain 4083-SVS6. Versipelostatin can be obtained from the culture supernatant by culturing the above-mentioned Streptomyces versipellis strain 4083-SVS6.
