Claim:
A compound represented by formula I: or a geometric isomer, enantiomer, diastereomer, racemate, pharmaceutically acceptable salt, or prodrug thereof, wherein X 1 is N, CR 4 ; where R 4 is hydrogen or aliphatic; L is absent or NH; Cy is aryl, substituted aryl, heteroaryl, or substituted heteroaryl; G is O or S; B is a linker; C is selected from: where W is O or S; Y is absent, N, or CH; Z is N or CH; R 7 and R 9 are independently hydrogen, OR′ or aliphatic group, wherein R′ is hydrogen, aliphatic, substituted aliphatic or acyl; provided that if R 7 and R 9 are both present, one of R 7 or R 9 must be OR′ and if Y is absent, R 9 must be OR′; and R 8 is hydrogen, acyl, aliphatic, or substituted aliphatic; where W is O or S; J is O, NH or NCH 3 ; and R 10 is hydrogen or lower alkyl; where W is O or S; Y 1 and Z 1 are independently N, C or CH; and where Z, Y, and W are as previously defined; R 11 and R 12 are independently selected from hydrogen or aliphatic; R 1 , R 2 and R 3 are independently selected from hydrogen, hydroxy, amino, halogen, alkoxy, substituted alkoxy, alkylamino, substituted alkylamino, dialkylamino, substituted dialkylamino, substituted or unsubstituted alkylthio, substituted or unsubstituted alkylsulfonyl, CF 3 , CN, N 3 , NO 2 , sulfonyl, acyl, aliphatic, substituted aliphatic, aryl, substituted aryl, heteroaryl, substituted heteroaryl, heterocyclic, and substituted heterocyclic; R 20 , R 21 and R 22 are independently selected from R 1 ; and R 23 is hydrogen, acyl, aliphatic or substituted aliphatic.
