Abstract
A novel fluorogenic alkyl diazirine photocrosslinker bearing an o-hydroxycinnamate moiety has been developed for identification of the targets of bioactive molecules. The o-hydroxycinnamate moiety can be converted to the corresponding 7-hydroxycoumarin derivative, which should be created on the interacting site within the photocaptured target protein. The label yield and fluorescence intensity have been immensely improved in comparison with our previous aromatic crosslinkers to facilitate target identification in small quantities.

Abstract
Fluorescent probes have gained profound use in biotechnology, drug discovery, medical diagnostics, molecular and cell biology. The development of methods for the translation of fluorophores into fluorescent probes continues to be a robust field for medicinal chemists and chemical biologists, alike. Access to new experimental designs has enabled molecular diversification and led to the identification of new approaches to probe discovery. This review provides a synopsis of the recent lessons in modern fluorescent probe discovery.

Abstract
A cutting-edge strategy for fluorogenic sensing of proteases (leucine aminopeptidase for the proof of concept) and based on the “covalent-assembly” principle is reported. Non-fluorescent mixed bis-aryl ethers are readily converted into a fluorescent pyronin through a domino process triggered by the peptide bond cleavage event caused by the targeted enzyme.

Abstract
High specificity has been an important feature in affinity labeling for target profiling. Especially, to label targets via rapidly progressing reactions with consumption of ligand (probe), high specificity of reaction with common functional groups of target protein should be achieved without reactions with similar groups of non-target proteins. Herein, we demonstrate the kinetic controlled affinity labeling of acyl CoA synthetase using a fatty acid analogue containing a phenylthioester linkage. High specificity was attained by accelerating the labeling rate in the binding pocket. This approach could be useful for profiling a series of target enzymes and transporters in signal transduction pathways.

Abstract
![]()
Transient
biomolecular interactions are the cornerstones of the
cellular machinery. The identification of the binding sites for low
affinity molecular encounters is essential for the development of
high affinity pharmaceuticals from weakly binding leads but is hindered
by the lack of robust methodologies for characterization of weakly
binding complexes. We introduce a paramagnetic ligand tagging approach
that enables localization of low affinity protein–ligand binding
clefts by detection and analysis of intermolecular protein NMR pseudocontact
shifts, which are invoked by the covalent attachment of a paramagnetic
lanthanoid chelating tag to the ligand of interest. The methodology
is corroborated by identification of the low millimolar volatile anesthetic
interaction site of the calcium sensor protein calmodulin. It presents
an efficient route to binding site localization for low affinity complexes
and is applicable to rapid screening of protein–ligand systems
with varying binding affinity.

Abstract
Target identification and confirmation for small molecules is often the rate limiting step in drug discovery. A robust method to identify proteins addressed by small molecules is affinity chromatography using chemical probes. These usually consist of the compound of interest equipped with a linker molecule and a proper tag. Recently, methods emerged that allow the identification of protein targets without prior functionalization of the small molecule of interest. The digest offers an update on the newest developments in the area of target identification with special focus on confirmation techniques.
