Abstract: Disclosed are uracil derivatives of the formula (I): wherein R1, R2, R3, and X are as defined herein, and use thereof as therapeutic agents. The uracil derivatives are used in particular together with a cytostatic agent for suppressing or reducing resistance building up on cytostatic treatment.

Abstract: The invention relates to special nucleosides, for example, a nucleoside of the formula I, wherein R1-R5 are as described herein, and also to drugs which contain these nucleosides. Furthermore, the invention relates to the use of such nucleosides in a method for suppressing or reducing the formation of resistance in the case of cytotstatic treatment of a cancer patient.

Abstract: Disclosed are uracil derivatives of the formula (I): wherein R1, R2, R3, and X are as defined herein, and use thereof as therapeutic agents. The uracil derivatives are used in particular together with a cytostatic agent for suppressing or reducing resistance building up on cytostatic treatment.

Abstract: The invention relates to the use of at least one overexpression inhibitor of DNA repair genes and oncogenes for producing a drug to increase the apoptotic effect of cytostatics after chemotherapy.

Abstract: The invention relates to methods of administration of at least one overexpression inhibitor of DNA repair genes and/or oncogenes (e.g., (E)-5-(2-bromovinyl)-2?-deoxyuridine (BVDU), or a prodrug, or salt thereof) to increase the cytotoxic effect of a cytostatic or cytotoxic chemotherapeutic agent during and/or after chemotherapy, e.g., in the treatment of cancer.

Abstract: The present invention relates to the use of 5-substituted nucleosides and/or the prodrugs thereof together with at least one active substance in order to produce a drug or combination preparation for resistance-free therapy of infectious diseases caused by bacteria or protozoa.

Abstract: The invention relates to a method of producing a composition and to a composition for preventing or reducing formation of resistance in cytostatic treatment comprising combining BVDU, a salt thereof or BVDU in protected form or in prodrug form with at least one cytostatic agent in order to prevent or reduce the formation of resistance during cytostatic treatment. The present invention is also directed to a method of reducing resistance in cytostatic treatment comprising delivering therapeutically-effective amount of at least one cytostatic agent and a therapeutically effective amount of BVDU, a salt thereof, or BVDU in protected form or in prodrug form.
