Outline of Final Research Achievements

The purpose of this study is to develop a novel screening system for exploration of Protein Kinase C (PKC) C1b-binding ligands. PKC activators can function as latency-reversing agents (LRAs) against Human Immunodeficiency Virus (HIV). In order to develop the HIV cure methods, LRAs are considered as a key player to completely eliminate the virus from the body. In this study, we developed a novel Forster resonance energy transfer (FRET)-based assay method to evaluate PKC C1b domain affinity of the test compounds. Additionally, we also conducted an SAR study of the PKC C1b-binding ligands and successfully found six novel PKC activators.

Academic Significance and Societal Importance of the Research Achievements

現在用いられている多剤併用療法 (Anti-Retroviral Therapy, ART) によるHIV治療はそのウイルス量を検出限界以下まで抑えることが可能である。しかし、HIVは投薬中、リザーバー細胞と呼ばれる細胞内で潜伏・休眠し、ARTを中止すると再び増殖を開始する。このため、HIVを完全に体内から除去する根治治療法の開発が望まれている。本研究によって見い出されたPKC活性化剤はHIV再活性化能を有しており、根治治療法開発に資することが期待される。
