  • Patent number: 4461894
    Abstract: Naphth[1,2-d]imidazoles and naphth[2,1-d]oxazoles of formula ##STR1## wherein R and R.sub.1 are hydrogen, halogen, alkyl or alkoxy, R.sub.2 is hydrogen or halogen and A is one of the following moieties ##STR2## wherein R.sub.3 is alkyl, cycloalkyl, or a --(CH.sub.2).sub.n NR.sub.5 R.sub.6 group in which n is 1, 2 or 3, R.sub.5 is hydrogen or alkyl, R.sub.6 is alkyl or R.sub.5 and R.sub.6 taken together with the adjacent nitrogen atom are a 4- to 7-membered saturated hetero ring which may contain a further hetero atom and optionally may be substituted, e.g., with phenyl or substituted phenyl, R.sub.4 is hydrogen, alkyl, cycloalkyl or a --(CH.sub.2).sub.n NR.sub.5 R.sub.6 group, provided that one of R.sub.3 and R.sub.4 is a --(CH.sub.2).sub.n --NR.sub.5 R.sub.6 group, and R.sub.7 is --(CH.sub.2).sub.n --NR.sub.5 R.sub.6, or a pharmaceutically-acceptable acid addition salt thereof. They are made by contacting a corresponding naphth[1,2-d]imidazole or a naphth[2,1-d]oxazole wherein one of R.sub.3 and R.sub.

  • Patent number: 4411907
    Abstract: 3H-naphth[1,2-d]imidazole derivatives of formula ##STR1## wherein R stands for hydrogen, methyl or ethyl, R.sub.1 represents hydrogen, methyl or ethyl, R.sub.2 represents hydrogen, methyl, ethyl, phenyl or substituted phenyl, the symbol R.sub.3 stands for a phenyl radical optionally substituted and R.sub.4 and R.sub.5, each independently, may represent hydrogen, halogen, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkylthio, (C.sub.1 -C.sub.4)alkoxy or halo-(C.sub.1 -C.sub.4)alkoxy, are described. Also described is the process for preparing the novel compounds, their use as antiinflammatory agents and the pharmaceutical compositions containing them.
