Compounds having particular interest as labels and various novel uses in diagnostics and therapeutics are provided which have structure (1)
1
wherein R
1
is a binding partner, a linker or H;
a and b are 0 or 1, provided that the total of a and b is 0 or 1;
A is N or C;
X is S, O, —C(O)—, NH or NCH
2
R

;
Y is —C(O)—;
Z is taken together with A to form an aryl or heteroaryl ring structure comprising 5 or 6 ring atoms wherein the heteroaryl ring comprises a single O ring heteroatom, a single N ring heteroatom, a single S ring heteroatom, a single O and a single N ring heteroatom separated by a carbon atom, a single S and a single N ring heteroatom separated by a carbon atom, 2 N ring heteroatoms separated by a carbon atom, or 3 N ring heteroatoms at least two of which are separated by a carbon atom, and wherein the aryl or heteroaryl ring carbon atoms are unsubstituted with other than H or at least 1 nonbridging ring carbon atom is substituted with R

or ═O;
R

, C≡N or halo, or an R
6
is taken together with an adjacent R
6
to complete a ring containing 5 or 6 ring atoms;
R
3
is a protecting group or H; and tautomers, solvates and salts thereof; and provided that where a is 0, b is 1, and R

is H or OH;
then Z is not unsubstituted phenyl.
Also provided are novel intermediates and methods for the preparation and use of the structure (1) compounds.
