The presently disclosed subject matter provides dyes having an improved photostability, biosensors comprising such dyes, and methods of use thereof, including methods for detecting target molecules in a sample under test and for live-cell imaging. The dyes can include a binding member, including a biomolecule or fragments thereof, which can interact with target molecules of interest and can be specific to a given conformational state or covalent modification, e.g., phosphorylation, of the target molecule. The presently disclosed dyes can be used for detecting changes in the binding, conformational change, or posttranslational modification of the target molecule.

Covalent, irreversible small-molecule inhibitors that modify the sulfenyl form (i.e., sulfenic acid, RSOH and sulfenamide, RSNR′2) of therapeutically important proteins (particularly kinases and phosphatases) are disclosed, where the compositions include a compound having a substituted aryl or heterocyclic core structure that promotes binding interactions with a specific protein, and a nucleophilic reaction center (carbon, nitrogen, sulfur, or phosphorous) that is capable of forming a covalent bond with a sulfenic acid- or sulfenamide-modified cysteine residue in the protein. Methods for synthesizing these compounds are also disclosed, as well as methods of using them for determining the bioactivity of a chemical composition comprising an active compound toward a specific protein and for determining the potency of an inhibitor against a specific protein.
