Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
70 words
A method of decreasing the absorption of dietary cholesterol and fats through the wall of the intestinal tract, said method comprising: administering to a mammal a small but cholesterol esterase inhibiting effective amount of a compound of the formula: ##STR6## wherein Z equals an aryl moiety selected from the group consisting of 2-naphthyl and p-acetamidophenyl, X and Y are oxygen, and R is a C 1 to C 8 alkyl.
Claim 2
Independent Claim
70 words
A method of decreasing the absorption of dietary cholesterol and fats through the wall of the intestinal tract, said method comprising: administering to a mammal a small but cholesterol esterase inhibiting effective amount of a compound of the formula: ##STR6## wherein Z equals an aryl moiety selected from the group consisting of 2-naphthyl and p-acetamidophenyl, X and Y are oxygen, and R is a C 1 to C 8 alkyl.
Claim 3
Dependent Claim
10 words
A carbamate ester of claim 1 wherein Z is 2-naphthyl.
Claim 4
Dependent Claim
39 words
A carbamate ester of claim 2 wherein an additional moiety W is attached to said 2-naphthyl, and W is selected from the group consisting of C 1 to C 8 alkyl, halides and C 1 to C 8 oxyalkyl.
Claim 5
Dependent Claim
14 words
A compound of claim 3 wherein R is C 1 to C 8 alkyl.
Claim 6
Dependent Claim
14 words
A compound of claim 3 wherein R is C 4 to C 8 alkyl.
Claim 7
Dependent Claim
57 words
A unit dosage pharmaceutical composition comprising a pharmaceutical carrier and from 0.01 mg to 1.0 mg/kg of body weight of a carbamate ester of the formula: ##STR7## wherein Z equals an aryl moiety selected from the group consisting of 2-naphthyl and p-acetamindophenyl, X and & are oxygen, and R is a C 1 to C 8 alkyl.
Claim 8
Dependent Claim
57 words
A unit dosage pharmaceutical composition comprising a pharmaceutical carrier and from 0.01 mg to 1.0 mg/kg of body weight of a carbamate ester of the formula: ##STR7## wherein Z equals an aryl moiety selected from the group consisting of 2-naphthyl and p-acetamindophenyl, X and & are oxygen, and R is a C 1 to C 8 alkyl.
Claim 9
Dependent Claim
10 words
A carbamate ester of claim 6 wherein Z is 2-naphthyl.
Claim 10
Dependent Claim
39 words
A carbamate ester of claim 7 wherein an additional moiety W is attached to said 2-naphthyl, and W is selected from the group consisting of C 1 to C 8 alkyl, halides and C 1 to C 8 oxyalkyl.
Claim 11
Dependent Claim
14 words
A compound of claim 8 wherein R is C 1 to C 8 alkyl.
Claim 12
Dependent Claim
14 words
A compound of claim 8 wherein R is C 4 to C 8 alkyl.
