Henri B. Kagan and Kenso Soai have been awarded the Nobel Prize in Chemistry by the Royal Swedish Academy of Sciences. The accolade recognizes their work for the “discovery of nonlinear effects and autocatalysis in asymmetrical organic synthesis.”
These scientists successfully solved a chemical conundrum that has puzzled chemists for over a century: the spontaneous emergence of homochirality. Homochirality refers to the characteristic found in living organisms, where only one of the two possible mirror-image versions of molecules, such as amino acids, is present. This discovery holds significant implications, particularly for the development of molecules that interact with biological systems, such as those used in pharmaceuticals.
Kagan made a crucial first step in 1986 by developing a new method to manipulate chemical reactions, allowing the creation of a greater excess of one mirror-image variant than previously thought possible. Soai built upon this progress, developing the first chemical reaction with the potential for homochirality in 1995. He ultimately presented a reaction in 2003 where only one of the two possible mirror-image variants was produced. The Academy stated that these breakthroughs are vital for chemists designing reactions to manufacture medicines.
In related news, the Karolinska Institute had previously announced that the Nobel Prize in Medicine this year will go to German researchers Peter Hegemann and Georg Nagel, along with US-American Karl Deisseroth, for their discoveries in light-controlled ion channels and optogenetics. Similarly, astrophysicist Francis Halzen, who is US-Belgian, celebrated the Nobel Prize in Physics for “crucial contributions to the IceCube neutrino observatory and the discovery of high-energy astrophysical neutrinos.”
The Academy is scheduled to announce the recipient of the Literature Nobel Prize on Thursday, while the Nobel Peace Prize will be revealed in Oslo on Friday. Following that, the Alfred Nobel Memorial Prize for Economic Sciences will be announced next week.
It is worth noting that the Nobel Prize stands as the highest recognition within its respective disciplines and is presented annually on December 10th, the anniversary of Alfred Nobel’s death. The Peace Prize is given in Oslo, but all other Nobel prizes are conferred in Stockholm.
