Abstract
Abstract Substituted naphthalenyloxy- or naphthalenylthiooxyamides of trans-1,2-diaminocyclohexanes possess selective kappa opioid receptor site binding activity and are thus useful as analgesic or diuretic agents. Methods of preparing the compounds, pharmaceutical compositions, and a method for their use as analgesic agents are also disclosed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A compound having structural formula 1 ##STR13## wherein R 1 and R 2 taken together with the nitrogen atom to which they are attached form a pyrrolidinyl ring; and where A is ##STR14## where n is an integer of from one to six; X is oxygen or sulfur; and R 6 and R 7 are independently hydrogen, fluorine, chlorine, bromine, nitro, alkyl of from one to four carbon atoms, alkoxy of from one to four carbon atoms, or acetoxy; or an N-oxide of the pyrrolidinyl nitrogen atom or pharmaceutically acceptable acid addition salts thereof.
Claim 2
Dependent Claim
94 words
A compound having structural formula 1 ##STR13## wherein R 1 and R 2 taken together with the nitrogen atom to which they are attached form a pyrrolidinyl ring; and where A is ##STR14## where n is an integer of from one to six; X is oxygen or sulfur; and R 6 and R 7 are independently hydrogen, fluorine, chlorine, bromine, nitro, alkyl of from one to four carbon atoms, alkoxy of from one to four carbon atoms, or acetoxy; or an N-oxide of the pyrrolidinyl nitrogen atom or pharmaceutically acceptable acid addition salts thereof.
