Compounds and methods are disclosed that are useful for noninvasive imaging in the near-infrared spectral range. The cyanine compounds of Formula (I), are presented: wherein Q is a portion of a polymethine bridge selected from the group consisting (Formula (X)). Also included are bioconjugates of the compounds of Formula (I), methods of labeling biomolecules with the compounds, and methods of imaging.
A symmetric cyanine of the formula:
wherein:
X is selected from the group consisting of O, S and C(CH3)2;
W represents non-metal atoms required to form a benzo-condensed or a naphto-condensed ring;
R1 is selected from the group consisting of (CH2)nCH3, (CH2)nSO3- and (CH2)nSO3H, wherein n is an integer selected from 0 to 6 when R1 is (CH2)nCH3, and n is an integer selected from 3 to 6 when R1 is (CH2)nSO3- or (CH2)nSO3H;
R2 and R3 are independently selected from the group consisting of H, a sulphonic moiety and a sulphonate moiety;
Q is selected from the group consisting of:
wherein q is 0 or 1 and D is selected from the group consisting of:
-C≡C-G;
and
wherein A is O or S and G is, or contains a N, O or S nucleophile moiety or is, or contains a moiety capable of reacting with N, O or S nucleophiles.
