Henri Kagan And Kenso Soai Awarded 2026 Nobel Prize In Chemistry
Henri B. Kagan and Kenso Soai were awarded the 2026 Nobel Prize in Chemistry for work explaining how molecular handedness can arise and for reaction designs that produce one molecular hand at scale.[1]
Kagan's discovery of non-linear effects and Soai's development of autocatalytic systems transformed how chemists design asymmetric catalysts and enabled reactions now used in pharmaceutical research.[1] Science described the prize as resolving chemistry's longstanding "asymmetry mystery" by linking lab-level chirality amplification to why biological molecules on Earth are one-handed.[1]
Kagan showed that small imbalances in catalyst-substrate interactions can be amplified through non-linear effects, while Soai demonstrated that certain reactions can self-amplify chirality through autocatalysis.[1] Those laboratory mechanisms gave chemists a practical toolkit to design reactions that reliably favor one enantiomer, a requirement for producing safe chiral drugs at scale.[1]
The announcement was reported across news outlets, including NPR.[2] Science's feature emphasized specific reaction examples and technical context that directly link the laureates' lab work to tools now used in pharmaceutical research.[1]
