Patent ID: 7053103

Claim:
A compound of Formula I or Formula II: wherein: R 1 is —NR a R b ; R 2 is hydrogen, C 1-6 alkyl, C 3-6 cycloalkyl, C 3-6 cycloalkylalkyl, C 1-6 alkylcarbonyl, C 1-6 alkylsulfonyl, aryl, or arylalkyl, wherein said aryl or arylalkyl is optionally substituted with one or more substituents independently selected from C 1-6 alkyl, haloalkyl, C 1-6 alkoxy, and halogen; R 3 and R 4 are each independently selected from hydrogen and C 1-6 alkyl, or R 3 and R 4 are taken together with the carbon to which they are attached to form a C 3-6 cycloalkyl ring; Ar is aryl optionally substituted with one or more substituents independently selected from the group consisting of C 1-6 alkyl, C 1-6 alkoxy, C 1-6 alkylthio, C 1-6 alkylsulfonyl, aminosulfonyl, monoalkylaminosulfonyl, dialkylaminosulfonyl, halogen, haloalkyl, cyano, nitro, and —NR a″ R b″ , where R a″ and R b″ are each independently selected from the group consisting of hydrogen, C 1-6 alkyl, and C 1-6 alkylcarbonyl; R a is C 1-6 alkyl, C 1-6 alkoxyalkyl, C 1-6 alkylthioalkyl; and R b is heteroarylalkyl; n is 1; a is a single bond; or individual isomers, racemic or non-racemic mixtures of isomers, or pharmaceutically acceptable salts thereof.
