SUBSTITUTED PYRIDO[3',2':4,5]THIENO[3,2-D]PYRIMIDINE-2,4(1 H,3H)-DIONES AND -4(3H)-ONES, PYRIDO[3',2':4,5]FURO[3,2-D]PYRIMIDINE-2,4(1 H,3H)-DIONES AND -4(3H)-ONES, AND USE THEREOF AS INHIBITORS OF TNF-ALPHA RELEASE

摘要

The invention relates to novel pyrido[3',2':4,5]thieno[3,2-d]pyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=C-H, Y=S), thieno[2,3-d:4,5-d']dipyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=N, Y=S), in addition to pyrido[3',2':4,5]furo[3,2-d]pyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=C-H, Y=0) and furo[2,3-d:4,5-d']dipyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=N, Y=O) of general formulae 1a and 1b. The invention also relates to a method for the production thereof, pharmaceutical preparations containing said compounds and/or tautomers thereof and physiologically compatible salts which can be produced therefrom and/or solvates thereof, in addition to the pharmaceutical use of said compounds, tautomers thereof, salts or solvates, as inhibitors of TNFa-release.
