Irradiation initiated 1,2-photo Brook rearrangement of acyl silanes generated α-siloxycarbene intermediates that were used for photoaffinity labeling. Optimization of the acyl silane group produced a probe capable of capturing small molecule–protein interactions.
The clickable and photoreactive amino acid is prepared in 11 steps from 3-(4-bromophenyl)-1-propanol.
We report the synthesis and biological profiling of photoreactive chemical probes based on an established plasmepsin X inhibitor scaffold. Maintained antimalarial and recombinant enzyme activity support their use in future chemical proteomic studies.
S-Adenosylmethionine (SAM) serves as an important substrate in a variety of biochemical reactions. We developed three SAM photoaffinity probes to label, enrich and identify SAM-binding proteins.
This study introduces new photoaffinity-based probes to identify mono-ADP-ribose readers. Using human cell extracts, it detects both known and potential readers, thereby improving our understanding of mono-ADP-ribosylation.
