Patent ID: 7297700

Claim:
A bicycloheteroaryl compound capable of modulating P2X 7 receptor activity, in vivo, having a formula: wherein A is selected from CR 2a R 2b ; B and Y are independently selected from CR 2a and CR 2a R 2b ; Z is CR 4 ; L 1 is a bond, —CO—, —SO 2 — or a C 1 -C 5 alkylene group which can be optionally substituted by a substituent selected from alkyl, hydroxy, hydroxyalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, halogen, carbamoyl, and C 1 -C 6 alkoxy; n is 0, 1, 2 or 3; R 1 is selected from a 3-13 membered cycloalkyl, which can be optionally substituted with one or more substituents independently selected from halo, hydroxyl, amino, cyano, sulfo, sulfanyl, sulfinyl, amido, carboxy, ester, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, and sulfonamido; each of R 2a , R 2b , R 2′ and R 2″ is independently selected from hydrogen, substituted or unsubstituted C 1 -C 6 alkyl; or any of R 2′ and R 2″ can join together to form a cycloalkyl or cycloheteroalkyl ring of 3-7 atoms; R 3 is selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted bicycloaryl, and substituted or unsubstituted bicycloheteroaryl; provided when R 3 is hydrogen, L 1 is a bond or a C 1 -C 5 alkylene group; R 4 is selected from H, alkyl, substituted alkyl, acyl, substituted acyl, substituted or unsubstituted acylamino, substituted or unsubstituted alkylamino, substituted or unsubstituted alkythio, substituted or unsubstituted alkoxy, alkoxycarbonyl, substituted alkoxycarbonyl, substituted or unsubstituted alkylarylamino, arylalkyloxy, substituted arylalkyloxy, amino, aryl, substituted aryl, arylalkyl, substituted or unsubstituted sulfoxide, substituted or unsubstituted sulfone, substituted or unsubstituted sulfanyl, substituted or unsubstituted aminosulfonyl, substituted or unsubstituted arylsulfonyl, sulfuric acid, sulfuric acid ester, substituted or unsubstituted dihydroxyphosphoryl, substituted or unsubstituted aminodihydroxyphosphoryl, azido, carboxy, substituted or unsubstituted carbamoyl, cyano, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloheteroalkyl, substituted or unsubstituted dialkylamino, halo, heteroaryloxy, substituted or unsubstituted heteroaryl, substituted or unsubstituted heteroalkyl, hydroxy, nitro, and thio; and the dotted bond is a single or a double bond; or a pharmaceutically acceptable salt thereof; and stereoisomers and tautomers thereof.
