2-(4-pyridyl)-5-aryloxazoles and certain quaternary salts of these compounds are useful as visible-wavelength lasing dyes. These dyes are used in solution with non-interferring polar solvents, such as low molecular weight alcohols, H.sub.2 O, and D.sub.2 O, to form lasing media useful in dye lasers. Such lasers generally include a reservoir for containing the laser dye solution and a pumping energy source operably coupled therewith for producing stimulated emission of the dye solution.

The invention relates to a method for identifying the function of a ligand L using chromophore-assisted laser inactivation (CALI), characterized by the stages:
a) selecting a ligand binding partner (LBP) with specificity for the ligand L,
b) coupling the LBP to a laser-activatable marker (tag) to form LBP-tag, where appropriate after previous modification of the LBP with the aim of more efficient binding to the marker,
c) bringing the ligand L into contact with at least one LBP-tag to form an L/LBP-tag complex, and
d) irradiating the L/LBP-tag complex with a laser beam, whereupon the irradiated LBP-tag selectively modifies the bound ligand, it being possible to interchange the sequence of stages b) and c).
The invention also relates to an apparatus for carrying out the method according to the invention.

We have developed a combinatorial method for the fast and effective synthesis of a library based on a known fluorescent dye, Dapoxyl(TM) using parallel solution-phase chemistry. By screening the 140 new compounds using fluorescence-based assays, we identified three new fluorescent dyes with novel properties. (C) 2002 Elsevier Science Ltd. All rights reserved.
