Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A method of treating atherosclerosis, reducing the cholesterol ester content of the arterial wall, inhibiting atherosclerotic lesion development and/or treating hyperlipidemia in a mammal in need of such treatment which comprises administering to said mammal an effective amount of a compound of the formula: ##STR5## wherein R 1 and R 2 are different and are independently selected from the group consisting of C 4 -C 12 alkyl, C 4 -C 12 alkenyl, C 4 -C 12 alkynyl, C 4 -C 12 cycloalkyl, C 4 -C 12 cycloalkylalkyl, C 7 -C 14 aralkyl, and C 7 -C 14 aralkyl in which an aromatic ring bears at least one substituent selected from the group consisting of C 1 -C 10 alkyl, C 1 -C 10 alkoxy, phenoxy, benzyloxy, methylenedioxy, C 1 -C 4 alkylthio, phenyl, halo, trihalomethyl, adamantyl, C 1 -C 4 carboalkoxy, and nitro.
Claim 2
Independent Claim
143 words
A method of treating atherosclerosis, reducing the cholesterol ester content of the arterial wall, inhibiting atherosclerotic lesion development and/or treating hyperlipidemia in a mammal in need of such treatment which comprises administering to said mammal an effective amount of a compound of the formula: ##STR5## wherein R 1 and R 2 are different and are independently selected from the group consisting of C 4 -C 12 alkyl, C 4 -C 12 alkenyl, C 4 -C 12 alkynyl, C 4 -C 12 cycloalkyl, C 4 -C 12 cycloalkylalkyl, C 7 -C 14 aralkyl, and C 7 -C 14 aralkyl in which an aromatic ring bears at least one substituent selected from the group consisting of C 1 -C 10 alkyl, C 1 -C 10 alkoxy, phenoxy, benzyloxy, methylenedioxy, C 1 -C 4 alkylthio, phenyl, halo, trihalomethyl, adamantyl, C 1 -C 4 carboalkoxy, and nitro.
Claim 3
Dependent Claim
25 words
A method as recited in claim 1, wherein R 1 is C 7 -C 14 aralkyl and R 2 is C 4 -C 12 alkyl.
Claim 4
Dependent Claim
21 words
A method as recited in claim 2, wherein R 1 is benzyl and R 2 is C 4 -C 12 alkyl.
Claim 5
Dependent Claim
12 words
A method as recited in claim 1, wherein the compound is 1-benzyl-1-(n-butyl)-3-(phenyl)urea.
Claim 6
Dependent Claim
30 words
A method of treating atherosclerosis in a mammal in need of such treatment which comprises administering to said mammal an antiatherosclerotic amount of a compound as recited in claim 1.
Claim 7
Dependent Claim
38 words
A method of reducing the cholesterol ester content of an arterial wall in a mammal in need of such treatment which comprises administering to said mammal a cholesterol ester-reducing amount of a compound as recited in claim 1.
Claim 8
Dependent Claim
34 words
A method of inhibiting atherosclerotic lesion development in a mammal in need of such treatment which comprises administering to said mammal an atherosclerotic lesion development-inhibiting amount of a compound as recited in claim 1.
Claim 9
Dependent Claim
31 words
A method of treating hyperlipidemia in a mammal in need of such treatment which comprises administering to said mammal an effective lipid-altering amount of a compound as recited in claim 1.
