The present invention relates to photoactivatable compounds and methods of use thereof for determining binding site and other structural information about RNA transcripts. The invention also provides methods of identifying RNA transcripts that bind compounds and are thus druggable, methods of screening drug candidates, and methods of determining drug binding sites and/or accessible or reactive sites on a target RNA.

of pyrones and pyrimidones was synthesized, and their potential to act as photoaffinityprobes 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.
