Patent ID: 8772499

Claim:
A compound according to Formula (I): or a salt thereof, wherein: R a and R b are each absent; u is 0; X 3 is CH 2 ; X 4 is (CH 2 ) m ; X 5 is (CH 2 ) n ; m and n are each 1; each Z 1 group is a substituent on the X 3 carbon atom of the ring containing X 3 , X 4 , and X 5 and is independently halogen oxo C 1 -C 4 -alkyl, or —OR c ; or two Z 1 groups that are situated on the X 3 carbon atom, together with the carbon atom to which they are attached, form a 5-membered monocyclic heterocycle ring comprising two oxygen ring atoms; R c is hydrogen C 1 -C 4 -alkyl; p is 1 or 2; X 1 is —OH and X 2 is hydrogen; G 1 is pyridinyl or pyrimidinyl; each of which is optionally substituted with 1, 2, or 3 substituents independently selected from the group consisting of halogen C 1 -C 6 -alkyl, C 1 -C 6 -haloalkyl, and N(R gc ) 2 ; R gc is hydrogen or C 1 -C 6 -alkyl; G 2 is G 2d ; G 2d is phenyl, pyridinyl, or pyrimidinyl; each of which is optionally substituted with 1, 2, or 3 substituents independently selected from the group consisting of halogen, —CN, C 1 -C 6 -alkyl, C 1 -C 6 -haloalkyl, and —OR f ; and R f is C 1 -C 6 -alkyl or C 1 -C 6 -haloalkyl.
