Abstract: Vitamin PP compounds and compounds with anti-pellagra activity such as nicotinic acid and nicotinamide are useful for the reduction, elimination, and prevention of side-effects of immunosuppressive and anti-cancer chemotherapy and diagnosis, especially those induced by the use of substituted pyridine carboxamides of formula I. Combinations containing compounds of formula I and the vitamin PP compounds and compounds with anti-pellagra activity are provided for these chemotherapies and diagnoses.

Abstract: The invention relates to new pyridylalkane, alkene, and alkine acid amides substituted with an aryl and/or heteroaryl residue according to the general formula (I), with a saturated or one or several-fold unsaturated hydrocarbon residue in the carboxylic acid group, methods for the synthesis of these compounds, medicaments containing these and their production as well as their therapeutic use, especially as cytostatic agents and immunosuppressive agents, for example in the treatment or prevention of various types of tumors and control of immune reactions such as autoimmune diseases.

Abstract: The invention relates to new pyridyl alkane acid amides according to general formula (I) as well as methods for their production, medicaments containing these compounds as well as their medical use, especially in the treatment of tumors or for immunosuppression

Abstract: The invention relates to a new pyridyl alkene and pyridyl alkine acid amides according to the general formula (I) as well as methods for their production, medicaments containing these compounds as well as their medical use, especially in the treatment of tumors or for immunosuppression.

Abstract: The invention relates to new pyridylalkane, alkene, and alkine carboxamides substituted with an imide with a saturated or one or several-fold unsaturated hydrocarbon residue in the carboxylic acid group according to general formula (I), wherein the residue E is a cyclic imide, methods for the production of these compounds, medicaments containing these and their production as well as their therapeutic use, especially as cytostatic agents and immunosuppressive agents, for example in the treatment or prevention of various types of tumors, inhibition of abnormal cell growth and control of immune reactions, for example autoimmune diseases.

Abstract: The invention relates to new piperazinyl-substituted pyridylalkane, alkene, and alkine acid amides substituted with saturated or one or several-fold unsaturated hydrocarbon residue in the carboxylic acid group according to the general formula (I) as well as methods for the production of these compounds, medicaments containing these and their production as well as their therapeutic use, especially as cytostatic agents and immunosuppressive agents, for example in the treatment or prevention of various types of tumors and control of immune reactions such as autoimmune diseases.

Abstract: The invention relates to new piperidinyl-substituted pyridyl carboxamides of the general formula (I), wherein the structure element E has meanings (E1) or (E2) and whereby the heterocyclic ring can optionally have a double bond. These substances have especially high cytostatic activities and pronounced immunosuppressive properties which make them suitable for therapeutic treatment in broad tumor spectrum.

Abstract: New biologically active compounds are described which inhibit the cellular formation of niacinamide mononucleotide, and essential intermediate of the NAD(P) biosynthesis in the cell. These compounds can represent the active ingredient of a pharmaceutical composition for the treatment of cancers, leukaemias or for immunosuppression. Furthermore, screening methods are described as a tool for detecting the above active compounds, and for examination of a given cell type for its dependency on niacinamide as a precursor for NAD synthesis.

Abstract: The invention relates to the use of pharmacologically valuable pyridyl alkane, pyridyl alkene and/or pyridyl alkine acid amides according to general formula (I) in the treatment of tumors or for immunosuppression.

Abstract: The invention relates to new pyridyl alkane acid amides according to general formula (I) as well as methods for their production, medicaments containing these compounds as well as their medical use, especially in the treatment of tumors or for immunosuppression.
