This invention relates to tricyclic non-peptide vasopressin antagonists which are useful in treating conditions where decreased vasopressin levels are desired, such as in congestive heart failure, in disease conditions with excess renal water reabsorption and in conditions with increased vascular resistance and coronary vasoconstriction, the compounds having the general structure: ##STR1##

3-Carboxamide derivatives of 5H-pyrrolo�2,1-c!�1,4!-benzodiazepines

Derivatives of 4-anilinoquinoline having the formula: ##STR1## where X is O or H.sub.2 and Z is 1-substituted-4-piperidinylamino or diloweralkylaminoloweralkyl inhibit binding of tritiated bradykinin to guinea pig ileum and inhibit bradykinin-induced writhing in mice. Bradykinin is a nonapeptide formed in plasma as a result of inflammation or injury and produces pain when it binds with pain receptors. A drug which inhibits the binding of bradykinin therefore has analgetic properties.

Derivatives of 4-anilinoquinoline-3-carboxamide as analgesic agents

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.
