研究機関	広島大学
研究代表者	木村榮一広島大学, 医学部, 教授 (30034010)
キーワード	大環状ポリアミン / 二核亜鉛錯体 / 抗HIV活性 / 核酸塩基認識 / 神経毒ガス / 解毒 / 亜鉛蛍光試薬 / ダンシルペンダント
研究概要	1.大環状テトラアミンの金属錯体を適当でスペーサーでつなげた二核錯体を各種合成し、それらが強い抗HIV活性を有することを発見した。これらは、次世代の抗エイズ薬のリ-ド化合物として大きな展開が期待される。 2.上記錯体や、新たに合成された機能性ペンダントをもつ大環状化合物が水中、生理pHで、ポリヌクレオチド(1本鎖および2本鎖)中のチミンまたはウラシルを選択的に認識し、それらに強く結合すること、および2本鎖(polyU-polyA、poly (dT) -poly (dA) )を1本鎖に解離させることを融点(Tm)、UV測定法などで明らかにした。 3.脂溶性アルキル基を大環状テトラアミンにつけた新規亜鉛錯体を合成した。それが特に農薬や神経毒ガスサリンなどのリン酸トリエステルの最もすぐれた加水分解(解毒)触媒として働くことを見出した。 4.ダンシル基をペンダントにもつ新規大環状テトラアミンを合成。それが亜鉛選択的蛍光試薬として、極めてすぐれていることを発見した。細胞内微量亜鉛の蛍光分析に用いた。
