Patent ID: 7538114

Claim:
A compound of Formula (I): wherein: n is an integer from 1 to 3; R 1 and R 2 are independently selected from hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, aryl, heteroaryl, cycloalkyl, or heterocyclyl wherein the aforementioned rings are optionally substituted with R a , R b , or R c independently selected from alkyl, halo, haloalkyl, alkoxy, haloalkoxy, hydroxy, cyano, monosubstituted amino, or disubstituted amino; or R 1 and R 2 , when attached to the same carbon atom, can combine to form cycloalkyl or monocyclic saturated heterocyclyl to give a spiro ring wherein the cycloalkyl or monocyclic saturated heterocyclyl can be optionally substituted with R d , R e , or R f independently selected from alkyl, alkoxy, fluoro, fluoroalkyl, fluoroalkoxy, hydroxy, monosubstituted amino, or disubstituted amino; or R 1 and R 2 , when attached to carbon atoms 2 and 5 or 3 and 6 positions of the piperazine ring, can combine to form —C 1 -C 3 — alkylene chain wherein one of the carbon atoms in the alkylene chain is optionally replaced by a —NR—, —O—, —S(O)n1- (where R is hydrogen or alkyl and n1 is 0-2) and further wherein one or two hydrogen atoms in the alkylene chain can be optionally substituted with one or two alkyl; R 3 , R 4 and R 5 are independently hydrogen, alkyl, fluoro, or fluoroalkyl; and Ar 1 and Ar 2 are independently aryl, heteroaryl, cycloalkyl, or heterocyclyl where each of the aforementioned ring is optionally substituted with R g , R h or R i where R g is alkyl, —C≡C—R 6 (where R 6 is aryl or heteroaryl), halo, haloalkyl, haloalkoxy, alkylthio, cyano, alkoxy, amino, monosubstituted amino, disubstituted amino, sulfonyl, acyl, carboxy, alkoxycarbonyl, hydroxyalkyl, alkoxyalkyl, aminoalkyl, hydroxyalkoxy, alkoxyalkoxy, aminoalkoxy, aminosulfonyl, aminocarbonyl, or acylamino and R h and R i are independently selected from alkyl, halo, haloalkyl, haloalkoxy, alkylthio, cyano, alkoxy, amino, monosubstituted amino, disubstituted amino, sulfonyl, acyl, carboxy, alkoxycarbonyl, hydroxyalkyl, alkoxyalkyl, aminoalkyl, hydroxyalkoxy, alkoxyalkoxy, aminoalkoxy, aminosulfonyl, aminocarbonyl, acylamino, aryl, heteroaryl, cycloalkyl, or heterocyclyl where the aromatic or alicyclic ring in R g , R h and R i is optionally substituted with R j , R k or R l which are independently selected from alkyl, halo, haloalkyl, haloalkoxy, alkylthio, cyano, alkoxy, amino, monosubstituted amino, disubstituted amino, sulfonyl, acyl, carboxy, alkoxycarbonyl, hydroxyalkyl, alkoxyalkyl, aminoalkyl, hydroxyalkoxy, alkoxyalkoxy, aminoalkoxy, aminosulfonyl, aminocarbonyl, or acylamino; or a pharmaceutically acceptable salt thereof provided that: the compound of Formula (I) is not 2-(4-benzhydrylpiperazin-1-yl)acetic acid; or 2-(4-((4-chlorophenyl)(phenyl)methyl)piperazin-1-yl)acetic acid; or a salt thereof.
