Outline of Final Research Achievements

The biggest goal of remedy of AIDS at the moment is removal of HIV reservoir from the patients, that is cure. We already developed an inhibitor of HIV release named L-HIPPO. It was further found that this compound causes accumulation of HIV proteins causing cellular death, and we named this phenomenon “lock-in and apoptosis”. This would lead to cure of AIDS in near future. Herein we tried to improve this method. For example, we synthesized prodrug of L-HIPPO to carry a highly negatively charged compound inside of a cell. It is under the final purification now. X-ray crystallographic study of IP6, a part of L-HIPPO, and its target protein MA was also performed to understand how L-HIPPO interacts with the MA.

Academic Significance and Societal Importance of the Research Achievements

現在、世界では3000万人以上のHIV感染者がいることが知られる。適切に抗HIV剤が投与されていれば、彼らは健常人とほぼ同じように生活することができる。しかし、HIV潜伏感染細胞は残ったままで、抗HIV剤の投与を中断するとHIVはすぐに体内で増える。本研究を発展させれば、このHIV潜伏感染細胞を感染者体内から除去することに繋がるはずである。この「ウイルスを細胞内に閉じ込めて細胞を殺す」という概念は新しく、HIVのみならず様々な抗ウイルス戦略に応用できるはずである。また、L-HIPPOのような非天然型イノシトールリン脂質誘導体を薬に発展させるという考え方も新しい。
