2026 Nobel Prize in chemistry awarded for ‘mirror image’ molecule research, with impact on pharmacology

Henri B. Kagan, 95, and Kenso Soai, 76, were awarded the 2026 Nobel Prize in Chemistry on Wednesday for their research into asymmetric organic synthesis. The scientists were recognized for their discovery of non-linear effects and autocatalysis, which helped resolve a long-standing scientific mystery regarding how to form specific, single mirror-image molecules.

Many biological molecules exist in two versions that are mirror images of one another, similar to left and right hands. The ability to isolate or synthesize a single version of these molecules is considered a significant advancement with substantial implications for pharmaceutical manufacturing and the broader field of pharmacology.
