Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 142 words
A method for alleviating hypertension in hypertensive mammals which comprises administering an effective dose of a compound having the formula ##STR15## or salt thereof, wherein R is hydrogen or lower alkoxy R 1 is hydrogen, lower alkanoyl or amino(imino)methyl; R 2 is hydrogen, lower alkyl or phenyl-lower alkylene; R 3 is hydrogen; lower alkanoyl, benzoyl or ##STR16## A is hydrogen, lower alkyl or hydroxy-lower alkylene; B is hydrogen, lower alkyl, phenyl, phenyl-lower alkylene, hydroxy-lower alkylene, hydroxyphenyl-lower alkylene, amino-lower alkylene, guanidino-lower alkylene, imidazolyl-lower alkylene, indolyl-lower alkylene, mercapto-lower alkylene, lower alkylthio-lower alkylene, carbamoyl-lower alkylene or carboxy lower alkylene; or A and B together from a (CH 2 ) p bridge which completes an unsubstituted ring of 5 or 6 atoms with the nitrogen and carbon to which they are joined or said ring substituted with a hydroxy group; and p is 3 or 4.
Claim 2
Independent Claim 142 words
A method for alleviating hypertension in hypertensive mammals which comprises administering an effective dose of a compound having the formula ##STR15## or salt thereof, wherein R is hydrogen or lower alkoxy R 1 is hydrogen, lower alkanoyl or amino(imino)methyl; R 2 is hydrogen, lower alkyl or phenyl-lower alkylene; R 3 is hydrogen; lower alkanoyl, benzoyl or ##STR16## A is hydrogen, lower alkyl or hydroxy-lower alkylene; B is hydrogen, lower alkyl, phenyl, phenyl-lower alkylene, hydroxy-lower alkylene, hydroxyphenyl-lower alkylene, amino-lower alkylene, guanidino-lower alkylene, imidazolyl-lower alkylene, indolyl-lower alkylene, mercapto-lower alkylene, lower alkylthio-lower alkylene, carbamoyl-lower alkylene or carboxy lower alkylene; or A and B together from a (CH 2 ) p bridge which completes an unsubstituted ring of 5 or 6 atoms with the nitrogen and carbon to which they are joined or said ring substituted with a hydroxy group; and p is 3 or 4.
Claim 3
Dependent Claim 19 words
A method as in claim 1 wherein the compound has the L-configuration with respect to the carbon bearing B.
Claim 4
Dependent Claim 38 words
A method as in claim 1 wherein ##STR17## in the formula is the radical of glycine, alanine, leucine, threonine, phenylalanine, lysine, arginine, glutamine, histidine, methionine, serine, cysteine, tyrosine, valine, asparagine, glutamic acid, proline, hydroxyproline, phenylglycine, tryptophane or N-methylphenylalanine.
Claim 5
Dependent Claim 49 words
A method for alleviating hypertension in hypertensive mammals which comprises administering an effective dose of a compound having the formula ##STR18## or salt thereof, wherein R, R 1 , R 2 and R 3 have the same meaning as in claim 1, and R 4 is hydrogen or hydroxy.
Claim 6
Dependent Claim 27 words
A method as in claim 1 wherein the compound in the formula has A and B together as --(CH 2 ) 4 -- completing a six-membered ring.
Claim 7
Dependent Claim 55 words
A method as in claim 1 wherein the compound in the formula has R as hydroxy; R 1 as hydrogen; lower alkanoyl, or amino(imino)methyl; R 2 as hydrogen, lower alkyl or phenyl-lower alkylene; R 3 as hydrogen, lower alkanoyl or benzoyl; A as hydrogen; B as lower alkyl, guanidino-lower alkylene, amino-lower alkylene or phenyl-lower alkylene.
Claim 8
Dependent Claim 17 words
A method as in claim 1 wherein the compound in the formula has R 3 as ##STR19##
Claim 9
Dependent Claim 16 words
A method as in claim 1 wherein the compound in the formula has R as hydroxy.
Claim 10
Dependent Claim 21 words
A method as in claim 4 wherein the compound in the formula has R as hydroxy and R 4 as hydrogen.
Claim 11
Dependent Claim 31 words

Claim 13
Dependent Claim 16 words
A method as in claim 4 wherein the compound is cysteinylproline or acid addition salt thereof.
Claim 14
Dependent Claim 11 words

Claim 15
Dependent Claim 42 words
A method as in claim 4 wherein the compound in the formula has R as hydroxy; R 1 as hydrogen, lower alkanoyl or amino(imino)methyl; R 2 as hydrogen, lower alkyl or phenyl-lower alkylene; and R 3 as hydrogen, lower alkanoyl or benzoyl.
Claim 16
Dependent Claim 57 words
A method as in claim 1 wherein the compound in the formula has R as hydroxy; R 1 as hydrogen, lower alkanoyl or amino(imino)methyl; R 1 as hydrogen, lower alkyl or phenyl-lower alkylene; R 3 as hydrogen, lower alkanoyl or benzoyl; A as hydrogen; and B as methyl, propyl, isopropyl, butyl, isobutyl, guanidinopropyl, aminopropyl, aminobutyl or phenylmethyl.
