Abstract

The present invention relates to novel Bicyclic Heterocycle Compounds of Formula (I) and pharmaceutically acceptable salts thereof, wherein A, X, Y, Z, R1 R5, R6, and R7 are as defined herein. The present invention also relates to compositions comprising at least one Bicyclic Heterocycle Compound, and methods of using the Bicyclic Heterocycle Compounds for treating or preventing a herpesvirus infection in a patient.

First claim

What is claimed is:

X is —N— or —C(R 2 )—;
Y is —N— or —C(R 3 )—, such that only one of X and Y can be —N—;
Z is —N— or —C(R 4 )—;
R 1 is 5 to 7-membered monocyclic heterocycloalkyl or 9 or 10-membered bicyclic heterocycloalkyl, wherein said 5 to 7-membered monocyclic heterocycloalkyl group, and said 9 or 10-membered bicyclic heterocycloalkyl group can be optionally substituted with up to three R A groups, which can be the same or different, and wherein said 5 to 7-membered monocyclic heterocycloalkyl group, and said 9 or 10-membered bicyclic heterocycloalkyl group can optionally have a ring carbon atom functionalized as a carbonyl group;
R 2 is selected from H, C 1 -C 6 alkyl, —O—(C 1 -C 6 alkyl), C 1 -C 6 hydroxyalkyl, C 1 -C 6 aminoalkyl, —CN, —NH 2 , —C(O)O—(C 1 -C 6 alkyl), C 3 -C 7 cycloalkyl, C 4 -C 7 heterocycloalkyl, C 6 -C 10 aryl, 5 to 7-membered monocyclic heteroaryl, and 9 or 10-membered bicyclic heteroaryl, wherein said C 3 -C 7 cycloalkyl group, said C 6 -C 10 aryl group, said 5 to 7-membered monocyclic heteroaryl group, and said 9 or 10-membered bicyclic heteroaryl group can be optionally substituted with up to three RB groups, which can be the same or different, or where R 2 and R 3 , together with atoms to which they are attached, are joined to form a 5-membered heteroaryl group;
R 3 is selected from H, C 1 -C 6 alkyl, C 1 -C 6 hydroxyalkyl, 5 to 7-membered monocyclic heteroaryl, —O—(5 to 7-membered monocyclic heteroaryl), C 3 -C 7 cycloalkyl, wherein said C 3 -C 7 cycloalkyl group, and any of said 5 to 7-membered monocyclic heteroaryl groups, can be optionally substituted with up to three RC groups, which can be the same or different;
R 4 is selected from H, C 1 -C 6 alkyl, C 1 -C 6 hydroxyalkyl, and C 3 -C 7 cycloalkyl;
R 5 is selected from H, C 1 -C 6 alkyl, —OR 7 , —CN, —NH 2 , C 1 -C 6 hydroxyalkyl, C 1 -C 6 haloalkyl, —O—(C 1 -C 6 hydroxyalkyl), —(C 1 -C 6 alkylene)—NH—(C 1 -C 6 haloalkyl), —O—(C 1 -C 6 alkylene) m -(C 3 -C 7 cycloalkyl), —O—(C 1 -C 6 alkylene) m -(5 to 7-membered monocyclic heterocycloalkyl), and —(C 1 -C 6 alkylene) m -(5 to 7-membered monocyclic heterocycloalkyl), wherein said C 1 -C 6 alkyl group, said C 3 -C 7 cycloalkyl group, and said 5 to 7-membered monocyclic heterocycloalkyl group can each be optionally substituted with one or more substituents, each independently selected from —OH, C 1 -C 6 alkyl, and C 3 -C 7 cycloalkyl, and wherein said C 1 -C 6 haloalkyl can be optionally substituted with one —NH 2 group;
R 6 represents up to 3 phenyl ring substituents, which can be the same or different, and are each independently selected from C 1 -C 6 haloalkyl, C 1 -C 6 hydroxyalkyl, —CN, —NO 2 , —OR 7 , and halo;
each occurrence of R 7 is independently selected from H, C 1 -C 6 alkyl, and C 3 -C 7 cycloalkyl;
each occurrence of R A is independently selected from C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, C 1 -C 6 alkoxyalkyl, 5 to 7-membered monocyclic heterocycloalkyl, —C(O)—(C 1 -C 6 alkyl), and halo, wherein said 5 to 7-membered monocyclic heterocycloalkyl group can be optionally substituted with up to 3 substituents, which can be the same or different, and are each independently selected from C 1 -C 6 alkyl, 5 to 7-membered monocyclic heterocycloalkyl, and halo;
