The present invention relates to the use of pyridopyrimidine derivatives having the general formula (I) wherein X represents =NH, =N-Acyl, =O, or =S; R1 represents -NR3R4, -SR3, -SO-R3, -SO2-R3, -OR3; R2, R3, and R4 are independently of each other hydrogen, -(CH2)nPh*, heteroaryl, C3-C7-cycloalkyl, C1-C6-alkyl, C1-C6-alkanoyl, C2-C6-alkenyl, C2-C6-alkynyl; wherein the cycloalkyl, alkyl, alkanoyl, alkenyl, alkynyl residues can optionally substituted by one or more of the following groups: -NR5R6, phenyl, substituted phenyl, thioalkyl, alkyloxy, hydroxy, carboxy, halogen, cycloalkyl; R5 and R6 are independently of each other hydrogen, (CH2)nPh*, heteroaryl, C3-C7-cycloalkyl, C1-C6-alkyl, C1-C6-alkanoyl, C2-C6-alkenyl, C2-C6-alkynyl; R5 and R6 can be taken together with the nitrogen to which they are attached to complete a ring having 3 to 7 carbon atoms, optionally containing 1, 2, or 3 heteroatoms selected from nitrogen, oxygen, and sulfur; Ph* represents phenyl or substituted phenyl; n is 0, 1, 2, or 3; R4 can optionally be -CO-R3, -CO-OR3, -SO2-R3, -SO2-NR5R6, -CO-NR5R6, -CS-NR5R6, -C(=NH)-R3, -C(=NH)-NR5R6; R3 and R4 can be taken together with the nitrogen to which they are attached to complete a ring having 3 to 7 carbon atoms, optionally containing 1, 2, or 3 heteroatoms selected from nitrogen, oxygen, and sulfur; Ar represents phenyl, substituted phenyl, or heteroaryl; and pharmaceutically acceptable salts thereof for prophylaxis and/or treatment of inflammatory diseases, neurodegenerative disorders, immunological diseases, neuroimmunological diseases, autoimmune diseases, diabetes, transplant rejection, infective diseases, prion diseases, cardiovascular diseases and disorders.
