1-AZA-DIBENZOAZULENES AS INHIBITORS OF TUMOUR NECROSIS FACTOR PRODUCTION AND INTERMEDIATES FOR THE PREPARATION THEREOF

摘要

The present invention relates to 1-aza-dibenzoazulene derivatives of formula I, to their pharmacologically acceptable salts and solvates, to process and intermediates for the preparation thereof as well as to their antiinflammatory effects, especially to the inhibition of tumour necrosis factor-? (TNF-?) production and the inhibition of interleukin-1 (IL-1) production as well as to their analgetic action. Wherein X may be CH2 or a hetero atom such as 0, S, S(=0), S(=0)2, or NRa, wherein Ra is hydrogen or a protecting group; RI may be hydrogen, halogen, an optionally substituted C1-C7 alkyl or C2-C7 alkenyl, C2-C7 alkinyl, an optionally substituted aryl or heteroaryl and a heterocycle, hydroxy, hydroxy-C2-C7 alkenyl, hydroxy-C2-C7 alkinyl, C1-C7 alkoxy, thiol, thio-C2-C7 alkenyl, thio- C2-C7 alkinyl, C1-C7 alkylthio, amino, N-(C1---C7)alkylamino, N,N-di(C1-C7-a1kyl)amino, (C1-C7-alkyl)amino, amino-C2-C7 alkenyl, amino-C2-C7 alkinyl, amino-C1,-C7 alkoxy, C1-C7 alkanoyl, aroyl, oxo--C1-C7 alkyl, C1-C7 alkanoyloxy, carboxy, an optionally substituted C1-C7 alkyloxycarbonyl or aryloxycarbonyl, carbamoyl, N-(C1-C7-alkyl)carbamoyl, N,N-di(C1-C7-alkyl)carbamoyl, cyano, cyano-C1-C7 alkyl, sulfonyl, C1-C7 alkylsulfonyl, sulfinyl, C1-C7 alkylsulfinyl, nitro, or a substituent of the formula II.
