Patent ID: 7605265

Claim:
A compound of Formula I comprising a tetrahydroquinolinone moiety having an amino connecting substituent: wherein X 1 , X 2 are independently selected from H, alkyl, halo, alkoxy; L 1 , L 2 , L 3 , L 4 are bonds independently selected from bivalent C 1-5 alkylene; 1,4-cyclohexylene, 1,4-phenylene, —CO—, —O—, —S— and —NR—; R is selected from hydrogen, an unsubstituted or substituted alkyl, an unsubstituted or substituted cycloalkyl, unsubstituted or substituted alkenyl, or unsubstituted or substituted aryl; and the amino connecting substituent is in either the 5 or 6 position of the tetrahydroquinolinone moiety; with the proviso that if the amino connecting substituent of the tetrahydroquinolinone moiety is in the 5 position, and L 1 -L 2 -L 3 -L 4 is a C 3-12 methylene linker, then one of X 1 or X 2 is not H.
