Graphical representations of the database search and affinity selection strategies used to identify small molecules interacting with RNA. (a) Inforna search reveals that Targapremir-210 (TGP-210) targets the Dicer site of miRNA-210 featuring a 1 × 1 CC internal loop; (b) A 214 375-member library on polymeric microbeads was spatially segregated allowing for spatial differentiation between cyclic γ-AA peptides (surface) and a corresponding linear tag (core). The beads were incubated with the fluorescently labeled oligonucleotide containing the UPF1-binding RNA sequence. Highly fluorescent beads were isolated, the linear tag was released from the beads, and its sequence deconvoluted via tandem mass spectrometry
