Abstract:
A compound of formula (I): wherein: R1 is selected from the group consisting of hydrogen, aryl, aralkyl, heterocyclyl, diarylalkyl, heterocyclyl-alkyl, and lower alkyl; wherein the alkyl, aryl or heterocyclyl moieties in the foregoing groups may be substituted with one or more substituents independently selected from halogen, hydroxy, nitro, carboxy, cyano, amino, dialkylamino, lower alkoxy, lower alkyl, tri-halomethyl, alkylamino, carboxy and alkoxycarbonyl; R2 is selected from the group consisting of aryl, aralkyl, cycloalkyl, cycloalkyl-alkyl heterocyclyl, heterocyclyl-alkyl, diarylalkyl, aminoalkyl, tri-halomethyl, arylamino and lower alkyl; wherein the alkyl, aryl, heterocyclyl-alkyl, heterocyclyl, or amino moieties in the foregoing groups may be substituted with one or more substituents independently selected from halogen, hydroxy, nitro, cyano, amino, dialkylamino, lower alkoxy, lower alkyl, tri-halomethyl, alkylamino, phenyl, carboxy, carboxyalkyl and alkoxycarbonyl; each of X1 and X4 is C(O); each of X2 and X3 is absent; A is cycloalkyl-alkyl, where, in each case, the A group may optionally be substituted with one or more substituents selected from R7; where R7 is selected from alkyl, tri-halomethyl, cycloalkyl, aryl, aralkyl, heterocyclyl, heterocyclyl-alkyl, diarylalkyl, aminoalkyl, or arylamino; wherein the alkyl, aryl, heterocyclyl-alkyl, heterocyclyl, or amino moieties in the foregoing groups may be substituted with one or more substituents independently selected from halogen, hydroxy, nitro, cyano, amino, dialkylamino, lower alkoxy, lower alkyl, tri-halomethyl, alkylamino, phenyl, carboxy and alkoxycarbonyl; R3 is selected from the group consisting of hydrogen, aryl, heterocyclyl, aralkyl, diarylalkyl, heterocyclo-alkyl, tri-halomethyl, alkylamino, arylamino and lower alkyl; wherein the aryl, heterocyclyl, aralkyl, diarylalkyl, heterocyclyl-alkyl, alkylamino, arylamino or lower alkyl group may be substituted with one or more substituents independently selected from halogen, nitro, cyano, amino, dialkylamino, lower alkoxy, lower alkyl, tri-halomethyl, carboxy and alkoxycarbonyl; Y is selected from the group consisting of â€”Oâ€”, â€”Sâ€” and â€”SO2-; n is an integer from 0 to 5; R4 is a saturated monocyclic heterocyclyl; R5 is selected from the group consisting of hydrogen, halogen, nitro, cyano, amino, alkylamino, dialkylamino, trialkylamino, lower alkoxy, lower alkyl, tri-halomethyl, carboxy and alkoxycarbonyl; and the pharmaceutically acceptable salts and esters thereof.
