An efficient route is reported to 5- and 6-carboxy-X-rhodamines (compounds 1 and 2) that contain multiple n-propylene or gamma,gamma-dimethylpropylene groups bridging terminal nitrogen atoms and the central xanthene core. Gram quantities of these dyes are synthesized from inexpensive starting materials. The isolated products are activated by selective transformation of the carboxylic acid group into N-hydroxysuccinimidyl esters in situ and then conjugated with an amino group of a molecule of interest.
Disclosed herein, inter alia, are compounds, compositions, and methods of synthesizing labeled nucleosides.

Novel cannabinoid ligands represented by the general formulas I, II, and III and methods for preparation and use within which one or more of a fluorescent ligand, nitroxide spin label, metal chelate, biotin moiety, or group with enhanced polarity may be incorporated. The compounds can bind to and modulate the cannabinoid CB1 and CB2 receptors and thereby considered specific ligands for these receptors. Some of the disclosed compounds that bind to cannabinoid CB1 and CB2 receptors can exhibit tight or irreversible binding characteristics for these receptors. Due to the presence of the imaging/diagnostic and/or therapeutic functional groups including fluorescent groups, nitroxide spin labels, metal chelates, biotin moieties, and groups with enhanced polarity, the disclosed compounds may be useful as imaging/diagnostic tools and/or therapeutic agents.

The presently disclosed subject matter provides compositions that selectively bind cyclooxygenase-2 and comprise a therapeutic and/or diagnostic moiety. Also provided are methods for using the disclosed compositions for diagnosing (i.e., by imaging) a target cell and/or treating a disorder associated with a cyclooxygenase-2 biological activity.
