Outline of Final Research Achievements

All-trans-retinoic acid (ATRA) and its synthetic analogues (retinoic acids, RAs) play roles in inhibiting cancer development through activating nuclear receptors. Recently, the interest of RAs has been focused on their neuroprotection in central nervus system injury. In view of the chemical and metabolic instability of ATRA, we successfully synthesized the 11C-labeling of acyclic retinoid, which has the higher stability than ATRA, based on our original Palladium(0)-mediated rapid cross-coupling. PET studies on the both rat and monkey brains demonstrated that the 11C-labeled acyclic retinoid showed the high brain permeability. These results are important findings that could lead a retinoid drug candidate potential for chemotherapy of neurodegeneration.

Academic Significance and Societal Importance of the Research Achievements

本研究は,光や酸素に不安定なポリオレフィン構造から成り,化学的にも生物学的にも取扱いの難しい天然型環式レチノイドに代わるべく安定な非環式レチノイドの11C標識化と脳移行性の評価を主課題とし,実際に,パラジム0価錯体を介する独自の高速カップリング反応により11C標識化に成功するとともに,さらにPET研究により高い脳移行性を見出した。脳移行性の発見は,非環式レチノイド類のこれまでのがん研究に,新たな脳研究分野を加え,疾患診断や治療薬の開発を助長する重要な知見であり,学術的および社会的影響は大きい。
