諾貝爾化學獎由兩法日學者分享

今年的諾貝爾化學獎揭曉,由95歲的法國學者卡根(Henri B. Kagan)和76歲的日本學者峽合憲三(Kenso Soai)共同分享,以表彰他們在不對稱有機合成中發現非線性效應和自催化作用。

瑞典皇家科學院讚揚兩人,破解了一個困擾化學界超過一個世紀的謎題,就是同手性是如何自發產生,對製藥反應的設計有重要貢獻。

很多生命分子都存在兩種形態,兩者相似但不完全相同,就如同人類的左右手。

在設計藥物時,科學家希望能精準地選擇所需的鏡像分子。而兩人的研究找到方法,透過控制化學反應,偏向產生所需的其中一種鏡像分子,而非兩者各佔一半。

其中卡根發現放大這種偏向的方法;峽合憲三則設計出由產物促進自身生成的反應,最終只產生其中一邊的鏡像分子。

峽合憲三表示,接獲諾貝爾委員會通知獲獎時,正在家附近購物,形容是一生最興奮的日子之一。兩人將共享1200萬元瑞典克朗、折合122萬美元的獎金。
