Patent ID: 8299090

Claim:
A compound of Formula I: wherein: X is C 1 -C 9 alkylene, C 2 -C 9 alkenylene, or C 2 -C 9 alkynylene; Y is O or S; R 1 is hydrogen, hydroxy, or OR 7 ; R 2 , R 3 , and R 4 are independently hydrogen; R 5 and R 6 are each, independently, C 1 C 6 alkyl, wherein the alkyl is optionally substituted with one or more groups selected from hydroxy, C 1 -C 4 alkoxy, —CO 2 H, C 1 -C 6 alkoxycarbonyl, NH 2 , C 1 -C 6 mono- or dialkylamino, and halogen; or R 5 and R 6 together with the nitrogen to which they are attached form a saturated, partially unsaturated, or unsaturated 3 to 12 membered monocyclic or bicyclic heterocyclic ring optionally comprising from one to three additional ring heteroatoms selected from N, O, and S, and the remainder of the ring atoms are carbon atoms; R 7 is C 1 -C 6 alkyl, C 2 -C 6 alkenyl, or C 3 -C 7 cycloalkyl wherein the alkyl, alkenyl, and rings of the cycloalkyl are optionally substituted with one or more groups selected from hydroxy, C 1 -C 4 alkoxy, —CO 2 H, C 1 -C 6 alkoxycarbonyl, NH 2 , C 1 -C 6 mono- or dialkylamino, and halogen; or a pharmaceutically acceptable salt form thereof.
