α-Pyrones and pyrimidones are common structural motifs in natural products and bioactive compounds. They also display photochemistry that generates high-energy intermediates that may be capable of protein reactivity. A library of pyrones and pyrimidones was synthesized, and their potential to act as photoaffinity probes for nondirected affinity-based protein profiling in several crude cell lysates was evaluated. Further “proof-of-principle” experiments demonstrate that a pyrimidone tag on an appropriate scaffold is equally capable of proteome labeling as a benzophenone
