Henri B. Kagan and Kenso Soai won the Nobel Prize<\/a> in chemistry Wednesday for their efforts to resolve mysterious mirror images in chemical molecules, a discovery that transformed modern medicine.<\/p>\n

Many molecules of life come in versions that look alike but aren\u2019t exactly identical, like right and left hands. One mirror image of the chemical carvone smells like mint, for example, while the other has a whiff of caraway.<\/p>\n

When designing drugs to treat diseases, scientists want to be choosy about which mirror image they\u2019re getting. They want the version of a molecule that\u2019ll treat a cold, not the kind that\u2019ll make the sniffles worse.<\/p>\n

Kagan and Soai found ways to make chemistry pick a side, designing and manipulating reactions to produce the desired mirror image.<\/p>\n

\u201cThis is probably the coolest experiment in organic chemistry,\u201d said Peter Somfai, a member of the Nobel Committee for Chemistry. \u201cTaken together, the groundbreaking discoveries by Henri Kagan and Kenso Soai have reshaped our understanding of molecular chirality \u2014 how it is created, amplified and transmitted.\u201d<\/p>\n

The discovery enabled most modern medicines<\/p>\n

Scientists paid tribute to Kagan and Soai’s groundbreaking work, which the Nobel committee described as a feat never previously achieved by anyone \u201cother than life itself.\u201d<\/p>\n

\u201cIt might be difficult to say that this drug, or that drug, was developed using this,\u201d Somfai said. \u201cI would say all of them, because we use this as a tool, we use this as an understanding, how to develop catalysts, how they function.\u201d<\/p>\n

\u201cChirality\u201d comes from the Greek word for \u201chand.\u201d<\/p>\n

In the 1980s, Kagan\u2019s work showed there might be a way to design reactions to produce one form of a molecule over the other. Years later, Soai brought that dream to life. He created the first-ever chemical reaction to produce only one of a molecule\u2019s mirror images, in what\u2019s now known as the \u201cSoai reaction.\u201d<\/p>\n

\u201cThe medicines we have today would not be possible without this chemistry,\u201d said Rigoberto Hernandez, president of the American Chemical Society.<\/p>\n

Kagan, 95 years old and born in France, is affiliated with the Universit\u00e9 Paris-Sud in Orsay, France, and Soai, born in 1950 in Japan, with the Tokyo University of Science.<\/p>\n

The French Academy of Sciences, of which Kagan is a member, congratulated the two scientists and expressed its pride in the prize.<\/p>\n

Neither the Universit\u00e9 Paris-Sud nor the Tokyo University of Science responded immediately to AP requests for comment.<\/p>\n

\u201cI\u2019m very excited to receive the very nice news,\u201d Soai told the committee and journalists by phone. \u201cOf course this is one of the most exciting days in my life.\u201d<\/p>\n

He said he was shopping near his home when he was reached by the Nobel committee.<\/p>\n

More Nobel prizes will be awarded over the next week<\/p>\n

The Royal Swedish Academy of Sciences announced the winner in Stockholm.<\/p>\n

Last year, three scientists won the chemistry Nobel<\/a> for their development of new molecular structures that can trap vast quantities of gas inside, laying the groundwork to potentially suck greenhouse gases out of the atmosphere or harvest moisture from desert environments.<\/p>\n

This year’s prizes began with the Nobel for medicine, awarded Monday to three scientists whose work led to a tool that uses light to help unravel how the brain works<\/a>. The physics award Tuesday recognized a scientist’s efforts to demystify a rare group of neutrinos<\/a>.<\/p>\n

The literature prize is set to be awarded Thursday. After Friday\u2019s peace prize is awarded, the Nobel Memorial Prize in Economic Sciences will be announced Monday.<\/p>\n

The prize money this year is 12 million Swedish kronor (about $1.2 million), whether for an individual, a small group of laureates or an organization.<\/p>\n
