8-(Benzo[c]thiadiazolyl, benzo[c]furazanyl, or 2-methyl-2H-benzo[d]triazolyl)-quinolines, in free or N-oxide or acid addition or ammonium salt form, are novel and found to be useful as pharmaceuticals, e.g., as PDEIV inhibitors, for example in the treatment of asthma. Novel methods of treatment using the compounds, processes for making the compounds, and pharmaceutical compositions comprising the compounds are also provided. For example, compounds of formula (1), wherein X is -O-, -S-, or -N(CH3)-, R1 is hydrogen or (C1-4)alkyl, and R2 is (C1-4)alkyl or pyridyl, in free or N-oxide or pharmaceutically acceptable acid addition or ammonium salt form. |
