Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 85 words
The method for the treatment and control of diarrhea which comprises administering to a mammal suffering from diarrhea a therapeutically effective quantity of an N-aryl-anthranilic acid of the formula: ##STR9## and the pharmaceutically acceptable salts thereof, wherein Y represents trifluoromethyl, difluoromethyl, or nitro, X represents hydrogen, bromo, chloro or nitro, and R represents OH, -O-lower alkyl, O-CH 2 CHOHCH 2 OH, O-alkyl-NR 1 R 2 , NHOH or NR 1 NR 2 , wherein R 1 and R 2 are each hydrogen or lower alkyl.
Claim 2
Independent Claim 85 words
The method for the treatment and control of diarrhea which comprises administering to a mammal suffering from diarrhea a therapeutically effective quantity of an N-aryl-anthranilic acid of the formula: ##STR9## and the pharmaceutically acceptable salts thereof, wherein Y represents trifluoromethyl, difluoromethyl, or nitro, X represents hydrogen, bromo, chloro or nitro, and R represents OH, -O-lower alkyl, O-CH 2 CHOHCH 2 OH, O-alkyl-NR 1 R 2 , NHOH or NR 1 NR 2 , wherein R 1 and R 2 are each hydrogen or lower alkyl.
Claim 3
Dependent Claim 9 words
The method of claim 1 wherein R is OH.
Claim 4
Dependent Claim 10 words

Claim 13
Dependent Claim 72 words
The compounds of the formula: ##STR10## and the pharmaceutically acceptable salts thereof, wherein X' is H, chloro, bromo or nitro, Y is trifluoromethyl, difluoromethyl, or nitro, and R represents OH,-O-lower alkyl O-CH 2 CHOHCH 2 OH, NHOH, -0-alkyl NR 1 R 2 , or NR 1 NR 2 , wherein R 1 and R 2 are each hydrogen or lower alkyl, with the proviso that when X' is hydrogen, Y is difluoromethyl.
Claim 14
Dependent Claim 11 words
