Outline of Final Research Achievements

In order to develop new therapeutic agents against genetic diseases, I have performed structural studies of the ribosomal RNA molecular switches of several different organisms/cells by X-ray analysis and have designed and synthesized new drug compounds based on the obtained structural data. We have succeeded to design and synthesize several compounds possessing high readthrough, antiprotozoal or antibacterial activity and less toxicity against human. Especially, one of the designed/synthesized fluorinated aminoglycosides specifically binds to the RNA molecular switches of eukaryote and antibiotic-resistant bacteria. This compound can be a potent therapeutic agent against genetic diseases caused by nonsense mutations.
