Substituted quinolinyl- and naphthalenylbenzamides or benzylamines and related compounds useful as analgesics

Abstract

This invention relates to novel quinolinyl- and naphthalenylbenzamides or benylamines and related disclosed compounds of the formula ##STR1## wherein X is nitrogen, NO or CR.sup.1 ; Y is C(R.sup.1)(R.sup.2)O, OC(R.sup.1)(R.sup.2), C(R.sup.1)(R.sup.2)N(R.sup.3), N(R.sup.3)C(R.sup.1)(R.sup.2) or C(R.sup.1).dbd.C(R.sup.2); wherein R.sup.1, R.sup.2, and R.sup.3 are independently hydrogen or lower alkyl containing 1 to 10 carbon atoms; Z is oxygen or (R.sup.1)(R.sup.2); R.sup.4 is R.sup.1, benzyl, benzyl ring substituted with R.sup.5, benzyl alpha monosubstituted with R.sup.1, benzyl ring substituted with R.sup.5 and alpha monosubstituted with R.sup.1, phenyl, phenylalkyl containing 2 to 10 carbon atoms in the alkyl group or phenylalkyl ring substituted with R.sup.5 and containing 2 to 10 carbon atoms in the alkyl group; wherein R.sup.5 is R.sup.1, lower alkoxy containing 1 to 10 carbon atoms, halogen, trihalomethyl, NO.sub.2, N(R.sup.1)(R.sup.2) or C(O)N(R.sup.1)(R.sup.2); R.sup.6 is R.sup.1 or R.sup.6 is C(O)(R.sup.7) with the proviso that Z is not oxygen; and wherein R.sup.7 is R.sup.1, phenyl, perfluoroalkyl containing 1 to 10 carbon atoms, phenylalkyl containing 1 to 10 carbon atoms in the alkyl group; or a pharmaceutically acceptable acid addition salt thereof, and their use in the treatment of pain mediated by the biological peptide, bradykinin. In particular, the preferred compounds are where X is nitrogen, and Y is CH.sub.2 O of the above structure.
