Stockholm:French scientist Henri Kagan and Japan's Kenso Soai have been awarded the 2026 Nobel Prize in Chemistry. Their groundbreaking research addressed a longstanding scientific challenge related to molecules that exist in two mirror-image forms, providing crucial tools for designing chemical reactions essential in pharmaceutical manufacturing.
According to Qatar News Agency, Kagan, aged 95, and Soai, 76, built upon the foundational discoveries of French chemist Louis Pasteur from the 19th century. Their work focused on stereoisomerism, a phenomenon where many life-essential molecules exist in two mirror-image forms, with living organisms typically utilizing one form over the other.
The Nobel Committee highlighted that the duo's discoveries have shown how chemical reactions can be manipulated to selectively produce one molecular form. This advancement is particularly significant in drug development, as different molecular forms can have distinct effects.
Kagan and Soai will share a prize of 12 million Swedish kronor, approximately $1.2 million, and will receive their medals at a ceremony in Stockholm on December 10, marking the anniversary of Alfred Nobel's death. The Nobel Prizes, dating back to 1901, are awarded in the sciences, literature, and peace, with the economic sciences prize introduced later through funding from Sweden's central bank.
