pneumonia cause 100,000 deaths among the elderly with weak immunity in Japan every year. The major causative bacteria of pneumonia are Staphylococcus aureus and Streptococcus pneumoniae. And both bacteria have advanced drug resistance. Therefore, in this study, we selected a DNA sequence that changes its shape into a cubic structure in the presence of monovalent ions. We also searched the DNA sequences for sequences that specifically bind to various proteins which express bacteriial surfaces. We then attempted to construct a DNA antibacterial drug that sterically inhibits the methicillin‐resistant Staphylococcus aureus antibacterial factor by binding to the DNA sequence in a monovalent ion-dependent manner.
我が国のMRSA院内感染は深刻な状況であり,現在でも年間1万人以上が死亡していると推計されている.さらに,2050年以降は世界で毎年1000万人の耐性菌による感染死者が出るとWHOが警告している.しかし,新規抗菌薬の開発は困難さから世界中で停止し,挑戦するグループは殆ど存在しない.本研究で新規のMRSA治療薬の開発研究アイデアを発信できれば,世界的な研究を誘発することもあり得る.また,MRSA治療薬の素材としてDNAを活用する着想も,国内外へ波及する可能性を秘めている.
