Outline of Final Research Achievements

Although neuropathic and inflammatory pain are unbearable chronic pain by various diseases, effective analgesics with few side effects have yet to be developed. In this study, we aimed to establish the control system of neurotransmission for transporter-targeted drug discovery. We identified several selective inhibitors of vesicular neurotransmitter transporter, which were more effective for chronic pain with few side effects than existing drugs. These compounds are expected to become new drug candidates for neuropathic and inflammatory pain.

Academic Significance and Societal Importance of the Research Achievements

疼痛管理はQuality of Lifeの観点から重要であるが、副作用の少ない、効果的な鎮痛薬はこれまでにない。本研究により、化学伝達を司るトランスポーターの選択的阻害剤を同定し、既存の鎮痛薬よりも副作用なく、強力に鎮痛効果を発揮することを見出した。これら阻害剤は神経因性疼痛や炎症性疼痛の新しい創薬シーズになると期待される。
