Outline of Final Research Achievements

We hypothesized that conjugation of a hydrogen bonding module to the coumarin chromophore would be effective to modulate the electronic spectra upon binding to RNA, and may provide useful molecular indicators for structure-activity studies on small molecule-RNA interaction. the coumarin-naphthyridine conjugate TT7 showed marked absorption shift upon binding to the secondary structure of RNA. TT7-binding to the int-loop RNA was a good candidate of further study on the ligand-bound structure due to a clear 1:1 binding stoichiometry, a high affinity, and competitive binding to rev peptide. In addition, TT7 can be a potentially useful fluorescence indicator for FID assay of ligand binding to RNA of interests.
