Patent ID: 7674809

Claim:
A compound of formula (I): wherein: one of G 1 or G 2 is an amidine substituent of formula Q, and the other of G 1 or G 2 is independently selected from hydrogen, halogen, hydroxyl, C 1 -C 4 alkoxy and C 1 -C 4 alkyl; the amidine substituent of formula Q is represented by the structure given below, in which R is C 1 -C 4 alkyl or cycloalkyl; W independently represents a bond, Y is ═N—; X is —S—; R 1 and R 2 are independently selected from hydrogen, C 1 -C 4 alkyl, C 2 -C 4 alkenyl and C 1 -C 4 alkoxy; R 3 and R 4 are independently selected from hydrogen, halogen, hydroxyl, C 1 -C 4 alkoxy, C 1 -C 4 alkyl and C 2 -C 4 alkenyl; z is an aryl group, heteroaryl group, a linear or branched C 1 -C 6 alkyl or C 2 -C 6 alkenyl chain, C 1 -C 4 alkylene-aryl group, C 1 -C 4 alkylene-heteroaryl group, wherein, the aryl group is a phenyl which is unsubstituted or substituted with one or more substituents independently selected from halogen, trifluoromethyl, hydroxyl, nitro, cyano, carboxyl, carboxamido, carbonyl, thio, methylthio, methanesulfonyl, methanesulfinyl, sulfonamido, trifluoromethoxy, C 1 -C 6 alkoxy and C 1 -C 6 alkyl, and the heteroaryl group is a 5- or 6-atom heterocyclic aromatic ring containing one or more hetero atoms, which is unsubstituted or substituted with one or more substituents independently selected from halogen, trifluoromethyl, hydroxyl, nitro, cyano, carboxyl, carbonyl, thio, methylthio, methanesulfonyl, methanesulfinyl, trifluoromethoxy, C 1 -C 6 alkoxy and C 1 -C 6 alkyl; the C 1 -C 4 alkylene-aryl group is a linear or branched, saturated or unsaturated alkylene chain substituted with an aryl group provided that when the C 1 -C 4 alkylene chain is unsaturated, it has only one substituted or an unsubstituted double bond; substituents for the aryl group are independently selected from the groups defined above as substituents for the aryl group; the C 1 -C 4 alkylene-heteroaryl group is a linear or branched, saturated or unsaturated alkylene chain substituted with a substituted or an unsubstituted heteroaryl group; provided that when the C 1 -C 4 alkylene chain is unsaturated, it has only one substituted or unsubstituted double bond; and or pharmaceutically acceptable salts thereof.
