Claim:
A compound represented by the formula: or a racemate, enantiomer, regioisomer, salt, ester or prodrug thereof, wherein A and B are independently selected from the group consisting of hydrogen, deuterium, halogen, R 1 , OR 1 , S(O) n R 1 , —NR 1 C(O)R 2 , —NR 1 C(O)NR 3 R 4 , —NHS(O) n R 1 , —CONR 3 R 4 , and NR 3 R 4 ; R 1 and R 2 is independently selected from the group consisting of hydrogen, acyl, silane, a substituted or unsubstituted, saturated or unsaturated aliphatic group, a substituted or unsubstituted, saturated or unsaturated alicyclic group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group, saturated or unsaturated heterocyclic group; R 3 and R 4 is independently selected from the group consisting of hydrogen, acyl, a substituted or unsubstituted, saturated or unsaturated aliphatic group, a substituted or unsubstituted, saturated or unsaturated alicyclic group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group, saturated or unsaturated heterocyclic group; or can be taken together with the nitrogen atom to which they are attached to form a substituted or unsubstituted heterocyclic or heteroaromatic ring; or A and B, taken together with the carbon atom to which they are attached, form a substituted or unsubstituted alicyclic, aromatic, heterocyclic or heteroaromatic ring; or A and B, taken together with the carbon atom to which they are attached, are selected from the group consisting of CO, C═CHR 1 , C═NR 1 , C═NOR 1 , C═NO(CH 2 ) m R 1 , C═NNHR 1 , C═NNHCOR 1 , C═NNHCONR 1 R 2 , C═NNHS(O) n R 1 , or C═N—N═CHR 1 ; X and Y are independently selected from the group consisting of hydrogen, deuterium, halogen, R 1 , OR 1 , S(O) n R 1 , —NR 1 C(O)R 2 , —NR 1 C(O)NR 3 R 4 , —NR 1 S(O) n R 1 , —CONR 3 R 4 , and NR 3 R 4 ; or X and Y, taken together with the carbon atom to which they are attached, are selected from the group consisting of CO, C═CHR 1 , C═NR 1 , C═NOR 1 , C═NO(CH 2 ) m R 1 , C═NNHR 1 , C═NNHCOR 1 , C═NNHCONR 1 R 2 , C═NNHS(O) n R 1 , or C═N—N═CHR 1 ; L is selected from the group consisting of hydrogen, a substituted or unsubstituted, saturated or unsaturated aliphatic group, a substituted or unsubstituted, saturated or unsaturated alicyclic group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group, saturated or unsaturated heterocyclic group; W is NR 3 R 4 Z is hydrogen, alkyl or halogen; R 2 ′ is R 1 or a hydroxy protecting group; m is an integer; and n is 0, 1, or 2.
