Claim:
A compound having the following formula (VII) (VI)-R10 wherein (VI) is the formula: wherein R a is a bicyclic aryl group having 8 to 11 ring members, which may have 1 to 3 heteroatoms selected from nitrogen, oxygen and sulfur; R b is a monocyclic aryl group having 5 to 7 ring members, which may have 1 to 2 heteroatoms selected from nitrogen, oxygen or sulfur, and aryl ring in the compound may have one or more substituents selected from a group consisting of halogen, hydroxy, cyano, lower alkyl, and lower alkoxy groups; Rc is a saturated or unsaturated C 1-6 alkyl, C 1-6 alkoxy, perfluoro C 1-6 alkyl group; and X 1 , X 2 , and X 3 may be the same or different and independently selected from hydrogen, hydroxyl, and halogen; and Wherein one of R a , R b , R c , X 1 , X 2 , and X 3 is linked to R 10 via Y, Y is (a) an oxygen, sulfur, or nitrogen atom in R a , R b , and R c , or (b) an oxygen atom in X 1 , X 2 and X 3 when X 1 , X 2 or X 3 is hydroxyl; and Y—R 10 is hemimalate, dimethylaminoalkylcarbamate, or a salt thereof; or R 10 is hydroxyalkyl, glycosyl, substituted or unsubstituted piperidine oxycarbonyl, or a salt thereof.
