Abstract

Abstract The invention relates to fluorescent and/or reactive derivatives of 1,2-bis-(2-aminophenoxyethane)-N,N,N',N'-tetraacetic acid (BAPTA) according to the formula: ##STR1## where at least one of W and X is a functional group, with or without a spacer, that terminates in an alcohol or phenol, a thiol, a haloacetamide, an alkyl halide, an amine or aniline, a carboxylic acid, an anhydride, an isocyanate, an isothiocyanate, a maleimide, or an activated ester. The BAPTA-like molecule may be further substituted, one or more times, by additional functional groups with or without spacers or by CH 3 , NO 2 , CF 3 , F, Cl, Br, I, or carboxylic acid derivatives or pharmaceutically acceptable salts thereof, or by indolyl or benzofuran fluorophores. The functional groups allow for subsequent covalent attachment of one or more oxygen heterocycle fluorophores (e.g. fluorescein, coumarin, rhodamine); or polymolecular assemblies (e.g. gel and resin polymers, polysaccharides, polypeptides, nucleic acids, and liposomes); or combinations thereof.
