where:

(a) A 2 and A 3 are C or N;

(b) R 3 is hydrogen, alkyl, aralky, heteroaralkyl, alkenyl, aralkenyl, heteroaralkenyl, aryl, heteroaryl, or does not exist when A 3 is N;

(c) R 6 is hydrogen, alkyl, aralkyl, heteroaralkyl, aryl or heteroaryl;

(d) R 6 is hydrogen unless R 6 is alkyl, in which case R 6 is hydrogen or the same alkyl as R 6 ;

(e) L is a linker group; and

(f) B has the following formula:

where:

(i) R2 is hydrogen, alkyl, hydroxy, halo, alkoxy, cyano, methylthio;

(ii) R3 is hydrogen, alkyl, hydroxy, methoxy, halo, alkoxy, perfluoroalkyl, nitro, amino, aminocarbonyl, aminosulfonyl;

(iii) R2 and R3 can be taken together to form a 5 or 6 member aromatic or non-aromatic ring, which can contain from 0 to 3 heteroatoms selected from the group of N, O, or S;

(iv) R 4 is hydrogen, alkyl, halo, alkoxy, perfluoroalkyl, perfluoroalkoky, or nitro; and

(v) R 3 and R 4 when taken together can form a 5 or 6 membered ring and can contain one or more heteroatoms;

and pharmaceutically acceptable salts and esters thereof.
